For an overview of the operator, why W\&B uses it, and how configuration hierarchy works, see [Self-Managed](/platform/hosting/hosting-options/self-managed#about-the-wb-kubernetes-operator). ## Before you begin Before deploying W\&B with the Kubernetes Operator, ensure your infrastructure meets all requirements: 1. **Review infrastructure requirements**: See the [Self-Managed infrastructure requirements](/platform/hosting/self-managed/requirements/) page for comprehensive details on: * Software version requirements (Kubernetes, MySQL, Redis, Helm) * Hardware requirements (CPU architecture, sizing recommendations) * Kubernetes cluster configuration * Networking, SSL/TLS, and DNS requirements 2. **Obtain a W\&B Server license**: See the [License](/platform/hosting/self-managed/requirements#license) section on the Requirements page. 3. **Provision external services**: Set up MySQL, Redis, and object storage before deployment. For additional context, see the [reference architecture](/platform/hosting/self-managed/ref-arch/) page. ### MySQL Database W\&B requires an external MySQL database. For production, W\&B strongly recommends using managed database services: * [AWS RDS Aurora MySQL](https://aws.amazon.com/rds/aurora/) * [Google Cloud SQL for MySQL](https://cloud.google.com/sql/mysql) * [Azure Database for MySQL](https://azure.microsoft.com/en-us/products/mysql/) Managed database services provide automated backups, monitoring, high availability, patching, and reduce operational overhead. See the [reference architecture](/platform/hosting/self-managed/ref-arch/#mysql) for complete MySQL requirements, including sizing recommendations and configuration parameters. For database creation SQL, see the [bare-metal guide](/platform/hosting/self-managed/operator/#mysql-database). For questions about your deployment's database configuration, contact [support](mailto:support@wandb.com) or your AISE. For complete MySQL setup instructions including configuration parameters and database creation, see the [MySQL section in the requirements page](/platform/hosting/self-managed/requirements/#mysql-database). ### Redis W\&B depends on a single-node Redis 7.x deployment used by W\&B's components for job queuing and data caching. For convenience during testing and development of proofs of concept, W\&B Self-Managed includes a local Redis deployment that is not appropriate for production deployments. For production deployments, W\&B can connect to a Redis instance in the following environments: * [AWS Elasticache](https://aws.amazon.com/elasticache/) * [Google Cloud Memory Store](https://cloud.google.com/memorystore?hl=en) * [Azure Cache for Redis](https://azure.microsoft.com/en-us/products/cache) * Redis deployment hosted in your cloud or on-premise infrastructure See the [External Redis configuration section](#external-redis) for details on how to configure an external Redis instance in Helm values. ### Object storage W\&B requires object storage with pre-signed URL and CORS support. **Recommended storage providers:** * [Amazon S3](https://aws.amazon.com/s3/): Object storage service offering industry-leading scalability, data availability, security, and performance. * [Google Cloud Storage](https://cloud.google.com/storage): Managed service for storing unstructured data at scale. * [Azure Blob Storage](https://azure.microsoft.com/en-us/products/storage/blobs): Cloud-based object storage solution for storing massive amounts of unstructured data. * [CoreWeave AI Object Storage](https://docs.coreweave.com/products/storage/object-storage): High-performance, S3-compatible object storage service optimized for AI workloads. * Enterprise S3-compatible storage: [MinIO Enterprise (AIStor)](https://www.min.io/product/aistor), [NetApp StorageGRID](https://www.netapp.com/data-storage/storagegrid/), or other enterprise-grade solutions MinIO Open Source is in [maintenance mode](https://github.com/minio/minio) with no active development or pre-compiled binaries. For production deployments, W\&B recommends using managed object storage services or enterprise S3-compatible solutions such as MinIO Enterprise (AIStor). For detailed bucket provisioning instructions including IAM policies, CORS configuration, and access setup, see the [Bring Your Own Bucket (BYOB) guide](/platform/hosting/data-security/secure-storage-connector). See the [reference architecture object storage section](/platform/hosting/self-managed/ref-arch/#object-storage) for complete requirements. ### Provision your storage bucket Before configuring W\&B, provision your object storage bucket with proper IAM policies, CORS configuration, and access credentials. **See the [Bring Your Own Bucket (BYOB) guide](/platform/hosting/data-security/secure-storage-connector) for detailed step-by-step provisioning instructions for:** * Amazon S3 (including IAM policies and bucket policies) * Google Cloud Storage (including PubSub notifications) * Azure Blob Storage (including managed identities) * CoreWeave AI Object Storage * S3-compatible storage (MinIO Enterprise, NetApp StorageGRID, and other enterprise solutions) See the [Object storage configuration section](#object-storage-bucket) for details on how to configure object storage in Helm values. ### OpenShift Kubernetes clusters W\&B supports deployment on [OpenShift Kubernetes clusters](https://www.redhat.com/en/technologies/cloud-computing/openshift) in cloud, on-premises, and air-gapped environments. W\&B recommends you install with the official W\&B Helm chart. #### Run the container as an un-privileged user By default, containers use a `$UID` of 999. Specify `$UID` >= 100000 and a `$GID` of 0 if your orchestrator requires the container run with a non-root user. W\&B must start as the root group (`$GID=0`) for file system permissions to function properly. Configure security contexts for each W\&B component. For example, to configure the API component: ```yaml theme={null} api: install: true image: repository: wandb/megabinary tag: 0.74.1 # Replace with your actual version pod: securityContext: fsGroup: 10001 fsGroupChangePolicy: Always runAsGroup: 0 runAsNonRoot: true runAsUser: 10001 seccompProfile: type: RuntimeDefault container: securityContext: allowPrivilegeEscalation: false capabilities: drop: - ALL privileged: false readOnlyRootFilesystem: false ``` If needed, configure a custom security context for other components like `app` or `console`. For details, see [Custom security context](#custom-security-context). ## Deploy W\&B Server application **The W\&B Kubernetes Operator with Helm is the recommended installation method** for all W\&B Self-Managed deployments, including cloud, on-premises, and air-gapped environments. Choose your deployment method: W\&B provides a Helm Chart to deploy the W\&B Kubernetes operator to a Kubernetes cluster. This approach allows you to deploy W\&B Server with Helm CLI or a continuous delivery tool like ArgoCD. For deployment-specific considerations, see [Environment-specific considerations](#environment-specific-considerations) and [Deploy with Terraform on public cloud](#deploy-with-terraform-on-public-cloud). For disconnected environments, see [Deploy on Air-Gapped Kubernetes](/platform/hosting/self-managed/on-premises-deployments/kubernetes-airgapped/). Follow these steps to install the W\&B Kubernetes Operator with Helm CLI: 1. Add the W\&B Helm repository. The W\&B Helm chart is available in the W\&B Helm repository: ```shell theme={null} helm repo add wandb https://charts.wandb.ai helm repo update ``` 2. Install the Operator on a Kubernetes cluster: ```shell theme={null} helm upgrade --install operator wandb/operator -n wandb-cr --create-namespace ``` 3. Configure the W\&B operator custom resource to trigger the W\&B Server installation. Create a file named `operator.yaml` with your W\&B deployment configuration. Refer to [Configuration Reference](#configuration-reference-for-wb-server) for all available options. Here's a minimal example configuration: ```yaml theme={null} apiVersion: apps.wandb.com/v1 kind: WeightsAndBiases metadata: labels: app.kubernetes.io/name: weightsandbiases app.kubernetes.io/instance: wandb name: wandb namespace: default spec: values: global: host: https:// license: eyJhbGnUzaH...j9ZieKQ2x5GGfw bucket:
mysql: ingress: annotations: ``` 4. Start the Operator with your custom configuration so that it can install, configure, and manage the W\&B Server application: ```shell theme={null} kubectl apply -f operator.yaml ``` Wait until the deployment completes. This takes a few minutes. 5. To verify the installation using the web UI, create the first admin user account, then follow the verification steps outlined in [Verify the installation](#verify-the-installation). Deploy W\&B using Terraform for infrastructure-as-code deployments. Choose between: * **Helm Terraform Module**: Deploys the operator to existing Kubernetes infrastructure * **Cloud Terraform Modules**: Complete infrastructure + application deployment for AWS, Google Cloud, and Azure For deployment-specific considerations, see [Environment-specific considerations](#environment-specific-considerations) and [Deploy with Terraform on public cloud](#deploy-with-terraform-on-public-cloud). For disconnected environments, see [Deploy on Air-Gapped Kubernetes](/platform/hosting/self-managed/on-premises-deployments/kubernetes-airgapped/). #### Helm Terraform Module This method allows for customized deployments tailored to specific requirements, leveraging Terraform's infrastructure-as-code approach for consistency and repeatability. The official W\&B Helm-based Terraform Module is located [here](https://registry.terraform.io/modules/wandb/wandb/helm/latest). Use the following code as a starting point. It includes all necessary configuration options for a production grade deployment: ```hcl theme={null} module "wandb" { source = "wandb/wandb/helm" spec = { values = { global = { host = "https://" license = "eyJhbGnUzaH...j9ZieKQ2x5GGfw" bucket = {
} mysql = { } } ingress = { annotations = { "a" = "b" "x" = "y" } } } } } ``` Note that the configuration options are the same as described in [Configuration Reference](#configuration-reference-for-wb-server), but that the syntax has to follow the HashiCorp Configuration Language (HCL). The Terraform module creates the W\&B custom resource definition (CRD). To see how W\&B themselves use the Helm Terraform module to deploy Dedicated Cloud installations for customers, follow these links: * [AWS](https://github.com/wandb/terraform-aws-wandb/blob/45e1d746f53e78e73e68f911a1f8cad5408e74b6/main.tf#L225) * [Azure](https://github.com/wandb/terraform-azurerm-wandb/blob/170e03136b6b6fc758102d59dacda99768854045/main.tf#L155) * [Google Cloud](https://github.com/wandb/terraform-google-wandb/blob/49ddc3383df4cefc04337a2ae784f57ce2a2c699/main.tf#L189) #### Cloud Terraform Modules W\&B provides a set of Terraform Modules for AWS, Google Cloud and Azure. These modules deploy entire infrastructures including Kubernetes clusters, load balancers, MySQL databases and so on as well as the W\&B Server application. The W\&B Kubernetes Operator is already pre-baked with these official W\&B cloud-specific Terraform Modules with the following versions: | Terraform Registry | Source Code | Version | | ------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- | ------- | | [AWS](https://registry.terraform.io/modules/wandb/wandb/aws/latest) | [https://github.com/wandb/terraform-aws-wandb](https://github.com/wandb/terraform-aws-wandb) | v4.0.0+ | | [Azure](https://github.com/wandb/terraform-azurerm-wandb) | [https://github.com/wandb/terraform-azurerm-wandb](https://github.com/wandb/terraform-azurerm-wandb) | v2.0.0+ | | [Google Cloud](https://github.com/wandb/terraform-google-wandb) | [https://github.com/wandb/terraform-google-wandb](https://github.com/wandb/terraform-google-wandb) | v2.0.0+ | This integration ensures that W\&B Kubernetes Operator is ready to use for your instance with minimal setup, providing a streamlined path to deploying and managing W\&B Server in your cloud environment. For detailed instructions on using these cloud-specific modules, see [Deploy with Terraform on public cloud](#deploy-with-terraform-on-public-cloud) below. ### Verify the installation To verify the installation, W\&B recommends using the [W\&B CLI](/models/ref/cli/). The verify command executes several tests that verify all components and configurations. This step assumes that the first admin user account is created with the browser. Follow these steps to verify the installation: 1. Install the W\&B CLI: ```bash theme={null} pip install wandb ``` 2. Log in to W\&B: ```bash theme={null} wandb login --host=https://YOUR_DNS_DOMAIN ``` For example: ```bash theme={null} wandb login --host=https://wandb.company-name.com ``` 3. Verify the installation: ```bash theme={null} wandb verify ``` A successful installation and fully working W\&B deployment shows the following output: ```console theme={null} Default host selected: https://wandb.company-name.com Find detailed logs for this test at: /var/folders/pn/b3g3gnc11_sbsykqkm3tx5rh0000gp/T/tmpdtdjbxua/wandb Checking if logged in...................................................✅ Checking signed URL upload..............................................✅ Checking ability to send large payloads through proxy...................✅ Checking requests to base url...........................................✅ Checking requests made over signed URLs.................................✅ Checking CORs configuration of the bucket...............................✅ Checking wandb package version is up to date............................✅ Checking logged metrics, saving and downloading a file..................✅ Checking artifact save and download workflows...........................✅ ``` Contact W\&B Support if you encounter errors. ## Environment-specific considerations Kubernetes is the same whether it runs on-premises or in the cloud. The main differences are in naming and managed services (for example, MySQL vs RDS, or S3 vs on-premises object storage). This section covers considerations that vary by environment. ### On-premises and bare metal When deploying on on-premises or bare-metal Kubernetes, pay attention to the following. #### Load balancer configuration On-premises Kubernetes clusters typically require manual load balancer configuration. Options include: * **External load balancer**: Configure an existing hardware or software load balancer (F5, HAProxy, etc.) * **Nginx Ingress Controller**: Deploy nginx-ingress-controller with NodePort or host networking * **MetalLB**: For bare-metal Kubernetes clusters, MetalLB provides load balancer services For detailed load balancer configuration examples, see the [Reference Architecture networking section](/platform/hosting/self-managed/ref-arch#networking). #### Persistent storage Ensure your Kubernetes cluster has a StorageClass configured for persistent volumes. W\&B components may require persistent storage for caching and temporary data. Common on-premises storage options: * NFS-based storage classes * Ceph/Rook storage * Local persistent volumes * Enterprise storage solutions (NetApp, Pure Storage, etc.) #### DNS and certificate management For on-premises deployments: * Configure internal DNS records to point to your W\&B hostname * Provision SSL/TLS certificates from your internal Certificate Authority (CA) * If using self-signed certificates, configure the operator to trust your CA certificate See the [SSL/TLS requirements](/platform/hosting/self-managed/requirements#ssl-tls) for certificate configuration details. #### OpenShift deployments W\&B fully supports deployment on OpenShift Kubernetes clusters. OpenShift deployments require additional security context configurations due to OpenShift's stricter security policies. For OpenShift-specific configuration details, see [OpenShift Kubernetes clusters](#openshift-kubernetes-clusters) above. For comprehensive OpenShift examples in air-gapped environments, see [Deploy on Air-Gapped Kubernetes](/platform/hosting/self-managed/on-premises-deployments/kubernetes-airgapped#openshift-configuration). #### Object storage for on-premises and S3-compatible After provisioning your object storage bucket (see [Object storage provisioning](/platform/hosting/data-security/secure-storage-connector)), configure it in your W\&B Custom Resource. **AWS S3 (on-premises)** For on-premises AWS S3 (via Outposts or compatible storage): ```yaml theme={null} bucket: kmsKey: # Optional KMS key for encryption name: # Example: wandb path: "" # Keep as empty string provider: s3 region: # Example: us-east-1 ``` **S3-compatible storage (MinIO, Ceph, NetApp, etc.)** For S3-compatible storage systems: ```yaml theme={null} bucket: kmsKey: null name: # Example: s3.example.com:9000 path: # Example: wandb provider: s3 region: # Example: us-east-1 ``` To enable TLS for S3-compatible storage, append `?tls=true` to the bucket path: ```yaml theme={null} bucket: path: "wandb?tls=true" ``` The certificate must be trusted. Self-signed certificates require additional configuration. See the [SSL/TLS requirements](/platform/hosting/self-managed/requirements#ssl-tls) for details. **Important considerations for on-premises object storage** When running your own object storage, consider: 1. **Storage capacity and performance**: Monitor disk capacity carefully. Average W\&B usage results in tens to hundreds of gigabytes. Heavy usage could result in petabytes of storage consumption. 2. **Fault tolerance**: At minimum, use RAID arrays for physical disks. For S3-compatible storage, use distributed or highly available configurations. 3. **Availability**: Configure monitoring to ensure the storage remains available. **MinIO considerations** MinIO Open Source is in [maintenance mode](https://github.com/minio/minio) with no active development. Pre-compiled binaries are no longer provided, and only critical security fixes are considered case-by-case. For production deployments, W\&B recommends using managed object storage services or [MinIO Enterprise (AIStor)](https://min.io/product/aistor). Enterprise alternatives for on-premises object storage include: * [Amazon S3 on Outposts](https://aws.amazon.com/s3/outposts/) * [NetApp StorageGRID](https://www.netapp.com/data-storage/storagegrid/) * MinIO Enterprise (AIStor) * [Dell ObjectScale](https://www.dell.com/en-us/shop/cty/sf/objectscale) If you are using an existing MinIO deployment or MinIO Enterprise, you can create a bucket using the MinIO client: ```bash theme={null} mc config host add local http://$MINIO_HOST:$MINIO_PORT "$MINIO_ACCESS_KEY" "$MINIO_SECRET_KEY" --api s3v4 mc mb --region=us-east-1 local/wandb-files ``` ### Public cloud with Terraform For full infrastructure-plus-application deployment on AWS, Google Cloud, or Azure, see [Deploy with Terraform on public cloud](#deploy-with-terraform-on-public-cloud) below. ## Deploy with Terraform on public cloud W\&B recommends fully managed deployment options such as [W\&B Multi-tenant Cloud](/platform/hosting/hosting-options/multi_tenant_cloud) or [W\&B Dedicated Cloud](/platform/hosting/hosting-options/dedicated-cloud) deployment types. W\&B fully managed services are simple and secure to use, with minimum to no configuration required. W\&B provides Terraform modules for deploying the platform on public cloud providers. These modules automate the provisioning of infrastructure and installation of W\&B Server. Before you start, W\&B recommends that you choose one of the [remote backends](https://developer.hashicorp.com/terraform/language/backend) available for Terraform to store the [State File](https://developer.hashicorp.com/terraform/language/state). The State File is the necessary resource to roll out upgrades or make changes in your deployment without recreating all components. Select your cloud provider: W\&B recommends using the [W\&B Server AWS Terraform Module](https://registry.terraform.io/modules/wandb/wandb/aws/latest) to deploy the platform on AWS. The Terraform Module deploys the following mandatory components: * Load Balancer * AWS Identity & Access Management (IAM) * AWS Key Management System (KMS) * Amazon Aurora MySQL * Amazon VPC * Amazon S3 * Amazon Route53 * Amazon Certificate Manager (ACM) * Amazon Elastic Load Balancing (ALB) * Amazon Secrets Manager Optional components include: * Elastic Cache for Redis * SQS ### Pre-requisite permissions The account that runs Terraform needs to be able to create all components described above and permission to create **IAM Policies** and **IAM Roles** and assign roles to resources. ### General steps The steps in this section are common for any deployment option. 1. Prepare the development environment. * Install [Terraform](https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli) * W\&B recommend creating a Git repository for version control. 2. Create the `terraform.tfvars` file. The `tvfars` file content can be customized according to the installation type, but the minimum recommended will look like the example below. ```bash theme={null} namespace = "wandb" license = "xxxxxxxxxxyyyyyyyyyyyzzzzzzz" subdomain = "wandb-aws" domain_name = "wandb.ml" zone_id = "xxxxxxxxxxxxxxxx" allowed_inbound_cidr = ["0.0.0.0/0"] allowed_inbound_ipv6_cidr = ["::/0"] eks_cluster_version = "1.29" ``` Ensure to define variables in your `tvfars` file before you deploy because the `namespace` variable is a string that prefixes all resources created by Terraform. The combination of `subdomain` and `domain` forms the FQDN for your W\&B instance. In the example above, the W\&B FQDN will be `wandb-aws.wandb.ml` and the DNS `zone_id` where the FQDN record will be created. Both `allowed_inbound_cidr` and `allowed_inbound_ipv6_cidr` also require setting. In the module, this is a mandatory input. The following example permits access from any source to the W\&B installation. 3. Create the file `versions.tf` This file will contain the Terraform and Terraform provider versions required to deploy W\&B in AWS: ```bash theme={null} provider "aws" { region = "eu-central-1" default_tags { tags = { GithubRepo = "terraform-aws-wandb" GithubOrg = "wandb" Enviroment = "Example" Example = "PublicDnsExternal" } } } ``` Refer to the [Terraform Official Documentation](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#provider-configuration) to configure the AWS provider. Optionally, but highly recommended, add the [remote backend configuration](https://developer.hashicorp.com/terraform/language/backend) mentioned at the beginning of this documentation. 4. Create the file `variables.tf` For every option configured in the `terraform.tfvars` Terraform requires a correspondent variable declaration. ``` variable "namespace" { type = string description = "Name prefix used for resources" } variable "domain_name" { type = string description = "Domain name used to access instance." } variable "subdomain" { type = string default = null description = "Subdomain for accessing the Weights & Biases UI." } variable "license" { type = string } variable "zone_id" { type = string description = "Domain for creating the Weights & Biases subdomain on." } variable "allowed_inbound_cidr" { description = "CIDRs allowed to access wandb-server." nullable = false type = list(string) } variable "allowed_inbound_ipv6_cidr" { description = "CIDRs allowed to access wandb-server." nullable = false type = list(string) } variable "eks_cluster_version" { description = "EKS cluster kubernetes version" nullable = false type = string } ``` ### Recommended deployment This is the most straightforward deployment option configuration that creates all mandatory components and installs in the Kubernetes Cluster the latest version of W\&B. 1. Create the `main.tf` In the same directory where you created the files in the General Steps, create a file `main.tf` with the following content: ``` module "wandb_infra" { source = "wandb/wandb/aws" version = "~>7.0" namespace = var.namespace domain_name = var.domain_name license = var.license subdomain = var.subdomain zone_id = var.zone_id allowed_inbound_cidr = var.allowed_inbound_cidr allowed_inbound_ipv6_cidr = var.allowed_inbound_ipv6_cidr public_access = true external_dns = true kubernetes_public_access = true kubernetes_public_access_cidrs = ["0.0.0.0/0"] eks_cluster_version = var.eks_cluster_version } data "aws_eks_cluster" "eks_cluster_id" { name = module.wandb_infra.cluster_name } data "aws_eks_cluster_auth" "eks_cluster_auth" { name = module.wandb_infra.cluster_name } provider "kubernetes" { host = data.aws_eks_cluster.eks_cluster_id.endpoint cluster_ca_certificate = base64decode(data.aws_eks_cluster.eks_cluster_id.certificate_authority.0.data) token = data.aws_eks_cluster_auth.eks_cluster_auth.token } provider "helm" { kubernetes { host = data.aws_eks_cluster.eks_cluster_id.endpoint cluster_ca_certificate = base64decode(data.aws_eks_cluster.eks_cluster_id.certificate_authority.0.data) token = data.aws_eks_cluster_auth.eks_cluster_auth.token } } output "url" { value = module.wandb_infra.url } output "bucket" { value = module.wandb_infra.bucket_name } ``` 2. Deploy W\&B To deploy W\&B, execute the following commands: ``` terraform init terraform apply -var-file=terraform.tfvars ``` ### Enable Redis To use Redis to cache SQL queries and speed up the application response when loading metrics, add the option `create_elasticache_subnet = true` to the `main.tf` file: ``` module "wandb_infra" { source = "wandb/wandb/aws" version = "~>7.0" namespace = var.namespace domain_name = var.domain_name subdomain = var.subdomain zone_id = var.zone_id create_elasticache_subnet = true } [...] ``` ### Enable message broker (queue) To enable an external message broker using SQS, add the option `use_internal_queue = false` to the `main.tf` file: This is optional because W\&B includes an embedded broker. This option does not bring a performance improvement. ``` module "wandb_infra" { source = "wandb/wandb/aws" version = "~>7.0" namespace = var.namespace domain_name = var.domain_name subdomain = var.subdomain zone_id = var.zone_id use_internal_queue = false [...] } ``` ### Additional resources * [AWS Terraform Module documentation](https://registry.terraform.io/modules/wandb/wandb/aws/latest) * [AWS Terraform Module source code](https://github.com/wandb/terraform-aws-wandb) * [Migrate to operator-based AWS Terraform modules](#migrate-to-operator-based-aws-terraform-modules) W\&B recommends using the [W\&B Server Google Cloud Terraform Module](https://registry.terraform.io/modules/wandb/wandb/google/latest) to deploy the platform on Google Cloud. The module documentation is extensive and contains all available options that can be used. Before you start, W\&B recommends that you choose one of the [remote backends](https://developer.hashicorp.com/terraform/language/backend/remote) available for Terraform to store the [State File](https://developer.hashicorp.com/terraform/language/state). The State File is the necessary resource to roll out upgrades or make changes in your deployment without recreating all components. The Terraform Module deploys the following mandatory components: * VPC * Cloud SQL for MySQL * Cloud Storage Bucket * Google Kubernetes Engine * Memorystore for Redis * KMS Crypto Key * Load Balancer Optional components include: * Pub/Sub messages system ### Prerequisite permissions The account that will run Terraform needs to have the role `roles/owner` in the Google Cloud project used. ### General steps The steps in this section are common for any deployment option. 1. Prepare the development environment. * Install [Terraform](https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli). * W\&B recommends creating a Git repository with the code that will be used, but you can keep your files locally. * Create a project in [Google Cloud Console](https://console.cloud.google.com/). * Authenticate with Google Cloud (make sure to [install gcloud](https://cloud.google.com/sdk/docs/install) before) using `gcloud auth application-default login`. 2. Create the `terraform.tfvars` file. The `tvfars` file content can be customized according to the installation type, but the minimum recommended will look like the example below. ```bash theme={null} project_id = "wandb-project" region = "europe-west2" zone = "europe-west2-a" namespace = "wandb" license = "xxxxxxxxxxyyyyyyyyyyyzzzzzzz" subdomain = "wandb-gcp" domain_name = "wandb.ml" ``` The variables defined here need to be decided before the deployment. The `namespace` variable will be a string that will prefix all resources created by Terraform. The combination of `subdomain` and `domain` will form the FQDN that W\&B will be configured. In the example above, the W\&B FQDN will be `wandb-gcp.wandb.ml`. 3. Create the file `variables.tf`. For every option configured in the `terraform.tfvars` Terraform requires a correspondent variable declaration. ``` variable "project_id" { type = string description = "Project ID" } variable "region" { type = string description = "Google region" } variable "zone" { type = string description = "Google zone" } variable "namespace" { type = string description = "Namespace prefix used for resources" } variable "domain_name" { type = string description = "Domain name for accessing the Weights & Biases UI." } variable "subdomain" { type = string description = "Subdomain for access the Weights & Biases UI." } variable "license" { type = string description = "W&B License" } ``` ### Recommended deployment This is the most straightforward deployment option configuration that creates all mandatory components and installs in the Kubernetes Cluster the latest version of W\&B. 1. Create the `main.tf` In the same directory where you created the files in the General Steps, create a file `main.tf` with the following content: ``` provider "google" { project = var.project_id region = var.region zone = var.zone } provider "google-beta" { project = var.project_id region = var.region zone = var.zone } data "google_client_config" "current" {} provider "kubernetes" { host = "https://${module.wandb.cluster_endpoint}" cluster_ca_certificate = base64decode(module.wandb.cluster_ca_certificate) token = data.google_client_config.current.access_token } provider "helm" { kubernetes { host = "https://${module.wandb.cluster_endpoint}" cluster_ca_certificate = base64decode(module.wandb.cluster_ca_certificate) token = data.google_client_config.current.access_token } } # Spin up all required services module "wandb" { source = "wandb/wandb/google" version = "~> 10.0" namespace = var.namespace license = var.license domain_name = var.domain_name subdomain = var.subdomain } # You'll want to update your DNS with the provisioned IP address output "url" { value = module.wandb.url } output "address" { value = module.wandb.address } output "bucket_name" { value = module.wandb.bucket_name } ``` 2. Deploy W\&B. To deploy W\&B, execute the following commands: ``` terraform init terraform apply -var-file=terraform.tfvars ``` ### Enable Redis To use Redis to cache SQL queries and speed up the application response when loading metrics, add the option `create_redis = true` to the `main.tf` file: ``` [...] module "wandb" { source = "wandb/wandb/google" version = "~> 10.0" namespace = var.namespace license = var.license domain_name = var.domain_name subdomain = var.subdomain create_redis = true } [...] ``` ### Enable message broker (queue) To enable an external message broker using Pub/Sub, add the option `use_internal_queue = false` to the `main.tf` file: This is optional because W\&B includes an embedded broker. This option does not bring a performance improvement. ``` [...] module "wandb" { source = "wandb/wandb/google" version = "~> 10.0" namespace = var.namespace license = var.license domain_name = var.domain_name subdomain = var.subdomain use_internal_queue = false } [...] ``` ### Additional resources * [Google Cloud Terraform Module documentation](https://registry.terraform.io/modules/wandb/wandb/google/latest) * [Google Cloud Terraform Module source code](https://github.com/wandb/terraform-google-wandb) W\&B recommends using the [W\&B Server Azure Terraform Module](https://registry.terraform.io/modules/wandb/wandb/azurerm/latest) to deploy the platform on Azure. The module documentation is extensive and contains all available options that can be used. The Terraform Module deploys the following mandatory components: * Azure Resource Group * Azure Virtual Network (VPC) * Azure MySQL Flexible Server * Azure Storage Account & Blob Storage * Azure Kubernetes Service * Azure Application Gateway Optional components include: * Azure Cache for Redis * Azure Event Grid ### Pre-requisite permissions The simplest way to get the AzureRM provider configured is via [Azure CLI](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/guides/azure_cli) but in case of automation using [Azure Service Principal](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/guides/service_principal_client_secret) can also be useful. Regardless of the authentication method used, the account that will run Terraform needs to be able to create all components described above. ### General steps The steps in this section are common for any deployment option. 1. Prepare the development environment. * Install [Terraform](https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli) * W\&B recommends creating a Git repository with the code that will be used, but you can keep your files locally. 2. Create the `terraform.tfvars` file. The `tvfars` file content can be customized according to the installation type, but the minimum recommended will look like the example below. ```bash theme={null} namespace = "wandb" wandb_license = "xxxxxxxxxxyyyyyyyyyyyzzzzzzz" subdomain = "wandb-azure" domain_name = "wandb.ml" location = "westeurope" ``` The variables defined here need to be decided before the deployment. The `namespace` variable will be a string that will prefix all resources created by Terraform. The combination of `subdomain` and `domain` will form the FQDN that W\&B will be configured. In the example above, the W\&B FQDN will be `wandb-azure.wandb.ml`. 3. Create the file `versions.tf` This file will contain the Terraform and Terraform provider versions required to deploy W\&B in Azure: ```bash theme={null} terraform { required_version = "~> 1.3" required_providers { azurerm = { source = "hashicorp/azurerm" version = "~> 3.17" } } } ``` Refer to the [Terraform Official Documentation](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs) to configure the Azure provider. Optionally, but highly recommended, add the [remote backend configuration](https://developer.hashicorp.com/terraform/language/backend) mentioned at the beginning of this documentation. 4. Create the file `variables.tf` For every option configured in the `terraform.tfvars` Terraform requires a correspondent variable declaration. ```bash theme={null} variable "namespace" { type = string description = "String used for prefix resources." } variable "location" { type = string description = "Azure Resource Group location" } variable "domain_name" { type = string description = "Domain for accessing the Weights & Biases UI." } variable "subdomain" { type = string default = null description = "Subdomain for accessing the Weights & Biases UI. Default creates record at Route53 Route." } variable "license" { type = string description = "Your wandb/local license" } ``` ### Recommended deployment This is the most straightforward deployment option configuration that creates all mandatory components and installs in the Kubernetes Cluster the latest version of W\&B. 1. Create the `main.tf` In the same directory where you created the files in the General Steps, create a file `main.tf` with the following content: ```bash theme={null} provider "azurerm" { features {} } provider "kubernetes" { host = module.wandb.cluster_host cluster_ca_certificate = base64decode(module.wandb.cluster_ca_certificate) client_key = base64decode(module.wandb.cluster_client_key) client_certificate = base64decode(module.wandb.cluster_client_certificate) } provider "helm" { kubernetes { host = module.wandb.cluster_host cluster_ca_certificate = base64decode(module.wandb.cluster_ca_certificate) client_key = base64decode(module.wandb.cluster_client_key) client_certificate = base64decode(module.wandb.cluster_client_certificate) } } # Spin up all required services module "wandb" { source = "wandb/wandb/azurerm" version = "~> 1.2" namespace = var.namespace location = var.location license = var.license domain_name = var.domain_name subdomain = var.subdomain deletion_protection = false tags = { "Example" : "PublicDns" } } output "address" { value = module.wandb.address } output "url" { value = module.wandb.url } ``` 2. Deploy W\&B To deploy W\&B, execute the following commands: ``` terraform init terraform apply -var-file=terraform.tfvars ``` ### Enable Redis To use Redis to cache SQL queries and speed up the application response when loading metrics, add the option `create_redis = true` to the `main.tf` file: ```bash theme={null} # Spin up all required services module "wandb" { source = "wandb/wandb/azurerm" version = "~> 1.2" namespace = var.namespace location = var.location license = var.license domain_name = var.domain_name subdomain = var.subdomain create_redis = true [...] } ``` ### Enable message broker (queue) To enable an external message broker using Azure Event Grid, add the option `use_internal_queue = false` to the `main.tf` file: This is optional because W\&B includes an embedded broker. This option does not bring a performance improvement. ```bash theme={null} # Spin up all required services module "wandb" { source = "wandb/wandb/azurerm" version = "~> 1.2" namespace = var.namespace location = var.location license = var.license domain_name = var.domain_name subdomain = var.subdomain use_internal_queue = false [...] } ``` ### Additional resources * [Azure Terraform Module documentation](https://registry.terraform.io/modules/wandb/wandb/azurerm/latest) * [Azure Terraform Module source code](https://github.com/wandb/terraform-azurerm-wandb) ### Other deployment options You can combine multiple deployment options by adding all configurations to the same file. Each Terraform module provides several options that can be combined with the standard options and the minimal configuration found in the recommended deployment section. Refer to the module documentation for your cloud provider for the full list of available options: * [AWS Module documentation](https://registry.terraform.io/modules/wandb/wandb/aws/latest) * [Google Cloud Module documentation](https://registry.terraform.io/modules/wandb/wandb/google/latest) * [Azure Module documentation](https://registry.terraform.io/modules/wandb/wandb/azurerm/latest) ## Access the W\&B Management Console The W\&B Kubernetes operator comes with a management console. It is located at `${HOST_URI}/console`, for example `https://wandb.company-name.com/console`. There are two ways to log in to the management console: 1. Open the W\&B application in the browser and log in. Log in to the W\&B application with `${HOST_URI}/`, for example `https://wandb.company-name.com/` 2. Access the console. Click on the icon in the top right corner and then click **System console**. Only users with admin privileges can see the **System console** entry. System console access W\&B recommends you access the console using the following steps only if Option 1 does not work. 1. Open console application in browser. Open the above described URL, which redirects you to the login screen: Direct system console access 2. Retrieve the password from the Kubernetes secret that the installation generates: ```shell theme={null} kubectl get secret wandb-password -o jsonpath='{.data.password}' | base64 -d ``` Copy the password. 3. Log in to the console. Paste the copied password, then click **Login**. ## Update the W\&B Kubernetes operator This section describes how to update the W\&B Kubernetes operator. * Updating the W\&B Kubernetes operator does not update the W\&B server application. * See the instructions [here](#migrate-Self-Managed-instances-to-wb-operator) if you use a Helm chart that does not use the W\&B Kubernetes operator before you follow the following instructions to update the W\&B operator. Copy and paste the code snippets below into your terminal. 1. First, update the repo with [`helm repo update`](https://helm.sh/docs/helm/helm_repo_update/): ```shell theme={null} helm repo update ``` 2. Next, update the Helm chart with [`helm upgrade`](https://helm.sh/docs/helm/helm_upgrade/): ```shell theme={null} helm upgrade operator wandb/operator -n wandb-cr --reuse-values ``` ## Update the W\&B Server application You no longer need to update W\&B Server application if you use the W\&B Kubernetes operator. The operator automatically updates your W\&B Server application when a new version of the software of W\&B is released. ## Migrate Self-Managed instances to W\&B Operator The following section describes how to migrate from self-managing your own W\&B Server installation to using the W\&B Operator to do this for you. The migration process depends on how you installed W\&B Server: The W\&B Operator is the default and recommended installation method for W\&B Server. Reach out to [Customer Support](mailto:support@wandb.com) or your W\&B team if you have any questions. * If you used the official W\&B Cloud Terraform Modules, navigate to the appropriate documentation and follow the steps there: * [AWS](#migrate-to-operator-based-aws-terraform-modules) * [Google Cloud](#migrate-to-operator-based-google-cloud-terraform-modules) * [Azure](#migrate-to-operator-based-azure-terraform-modules) * If you used the [W\&B Non-Operator Helm chart](https://github.com/wandb/helm-charts/tree/main/charts/wandb), continue [here](#migrate-to-operator-based-helm-chart). * If you used the [W\&B Non-Operator Helm chart with Terraform](https://registry.terraform.io/modules/wandb/wandb/kubernetes/latest), continue [here](#migrate-to-operator-based-terraform-helm-chart). * If you created the Kubernetes resources with manifests, continue [here](#migrate-to-operator-based-helm-chart). ### Migrate to Operator-based AWS Terraform Modules For a detailed description of the migration process, continue [here](https://github.com/wandb/helm-charts/tree/main/charts/operator-wandb). ### Migrate to Operator-based Google Cloud Terraform Modules Reach out to [Customer Support](mailto:support@wandb.com) or your W\&B team if you have any questions or need assistance. ### Migrate to Operator-based Azure Terraform Modules Reach out to [Customer Support](mailto:support@wandb.com) or your W\&B team if you have any questions or need assistance. ### Migrate to Operator-based Helm chart Follow these steps to migrate to the Operator-based Helm chart: 1. Get the current W\&B configuration. If W\&B was deployed with an non-operator-based version of the Helm chart, export the values like this: ```shell theme={null} helm get values wandb ``` If W\&B was deployed with Kubernetes manifests, export the values like this: ```shell theme={null} kubectl get deployment wandb -o yaml ``` You now have all the configuration values you need for the next step. 2. Create a file called `operator.yaml`. Follow the format described in the [Configuration Reference](#configuration-reference-for-wb-operator). Use the values from step 1. 3. Scale the current deployment to 0 pods. This step is stops the current deployment. ```shell theme={null} kubectl scale --replicas=0 deployment wandb ``` 4. Update the Helm chart repo: ```shell theme={null} helm repo update ``` 5. Install the new Helm chart: ```shell theme={null} helm upgrade --install operator wandb/operator -n wandb-cr --create-namespace ``` 6. Configure the new helm chart and trigger W\&B application deployment. Apply the new configuration. ```shell theme={null} kubectl apply -f operator.yaml ``` The deployment takes a few minutes to complete. 7. Verify the installation. Make sure that everything works by following the steps in [Verify the installation](#verify-the-installation). 8. Remove to old installation. Uninstall the old helm chart or delete the resources that were created with manifests. ### Migrate to Operator-based Terraform Helm chart Follow these steps to migrate to the Operator-based Helm chart: 1. Prepare Terraform config. Replace the Terraform code from the old deployment in your Terraform config with the one that is described [here](#deploy-wb-with-helm-terraform-module). Set the same variables as before. Do not change .tfvars file if you have one. 2. Execute Terraform run. Execute terraform init, plan and apply 3. Verify the installation. Make sure that everything works by following the steps in [Verify the installation](#verify-the-installation). 4. Remove to old installation. Uninstall the old helm chart or delete the resources that were created with manifests. ## Configuration Reference for W\&B Server This section describes the configuration options for W\&B Server application. The application receives its configuration as custom resource definition named [WeightsAndBiases](#how-it-works). Some configuration options are exposed with the below configuration, some need to be set as environment variables. The documentation has two lists of environment variables: [basic](/platform/hosting/env-vars/) and [advanced](/platform/hosting/iam/advanced_env_vars/). Only use environment variables if the configuration option that you need is not exposed using the Helm Chart. ### Basic example This example defines the minimum set of values required for W\&B. For a more realistic production example, see [Complete example](#complete-example). This YAML file defines the desired state of your W\&B deployment, including the version, environment variables, external resources like databases, and other necessary settings. ```yaml theme={null} apiVersion: apps.wandb.com/v1 kind: WeightsAndBiases metadata: labels: app.kubernetes.io/name: weightsandbiases app.kubernetes.io/instance: wandb name: wandb namespace: default spec: values: global: host: https:// license: eyJhbGnUzaH...j9ZieKQ2x5GGfw bucket:
mysql: ingress: annotations: ``` Find the full set of values in the [W\&B Helm repository](https://github.com/wandb/helm-charts/blob/main/charts/operator-wandb/values.yaml). **Change only those values you need to override**. ### Complete example This example configuration deploys W\&B to Google Cloud Anthos using Google Cloud Storage: ```yaml theme={null} apiVersion: apps.wandb.com/v1 kind: WeightsAndBiases metadata: labels: app.kubernetes.io/name: weightsandbiases app.kubernetes.io/instance: wandb name: wandb namespace: default spec: values: global: host: https://abc-wandb.sandbox-gcp.wandb.ml bucket: name: abc-wandb-moving-pipefish provider: gcs mysql: database: wandb_local host: 10.218.0.2 name: wandb_local password: 8wtX6cJHizAZvYScjDzZcUarK4zZGjpV port: 3306 user: wandb redis: host: redis.example.com port: 6379 password: password api: enabled: true glue: enabled: true executor: enabled: true license: eyJhbGnUzaHgyQjQyQWhEU3...ZieKQ2x5GGfw ingress: annotations: ingress.gcp.kubernetes.io/pre-shared-cert: abc-wandb-cert-creative-puma kubernetes.io/ingress.class: gce kubernetes.io/ingress.global-static-ip-name: abc-wandb-operator-address ``` ### Host ```yaml theme={null} # Provide the FQDN with protocol global: # example host name, replace with your own host: https://wandb.example.com ``` ### Object storage (bucket) **AWS** ```yaml theme={null} global: bucket: provider: "s3" name: "" kmsKey: "" region: "" ``` **Google Cloud** ```yaml theme={null} global: bucket: provider: "gcs" name: "" ``` **Azure** ```yaml theme={null} global: bucket: provider: "az" name: "" secretKey: "" ``` **Other providers (Minio, Ceph, and other S3-compatible storage)** For other S3 compatible providers, set the bucket configuration as follows: ```yaml theme={null} global: bucket: # Example values, replace with your own provider: s3 name: storage.example.com kmsKey: null path: wandb region: default accessKey: 5WOA500...P5DK7I secretKey: HDKYe4Q...JAp1YyjysnX ``` For S3-compatible storage hosted outside of AWS, `kmsKey` must be `null`. To reference `accessKey` and `secretKey` from a secret: ```yaml theme={null} global: bucket: # Example values, replace with your own provider: s3 name: storage.example.com kmsKey: null path: wandb region: default secret: secretName: bucket-secret accessKeyName: ACCESS_KEY secretKeyName: SECRET_KEY ``` ### MySQL ```yaml theme={null} global: mysql: # Example values, replace with your own host: db.example.com port: 3306 database: wandb_local user: wandb password: 8wtX6cJH...ZcUarK4zZGjpV ``` To reference the `password` from a secret: ```yaml theme={null} global: mysql: # Example values, replace with your own host: db.example.com port: 3306 database: wandb_local user: wandb passwordSecret: name: database-secret passwordKey: MYSQL_WANDB_PASSWORD ``` ### License ```yaml theme={null} global: # Example license, replace with your own license: eyJhbGnUzaHgyQjQy...VFnPS_KETXg1hi ``` To reference the `license` from a secret: ```yaml theme={null} global: licenseSecret: name: license-secret key: CUSTOMER_WANDB_LICENSE ``` ### Ingress To identify the ingress class, see this FAQ [entry](#how-to-identify-the-kubernetes-ingress-class). **Without TLS** ```yaml theme={null} global: # IMPORTANT: Ingress is on the same level in the YAML as 'global' (not a child) ingress: class: "" ``` **With TLS** Create a secret that contains the certificate ```console theme={null} kubectl create secret tls wandb-ingress-tls --key wandb-ingress-tls.key --cert wandb-ingress-tls.crt ``` Reference the secret in the ingress configuration ```yaml theme={null} global: # IMPORTANT: Ingress is on the same level in the YAML as 'global' (not a child) ingress: class: "" annotations: {} # kubernetes.io/ingress.class: nginx # kubernetes.io/tls-acme: "true" tls: - secretName: wandb-ingress-tls hosts: - ``` In case of Nginx you might have to add the following annotation: ``` ingress: annotations: nginx.ingress.kubernetes.io/proxy-body-size: 0 ``` ### Custom Kubernetes ServiceAccounts Specify custom Kubernetes service accounts to run the W\&B pods. The following snippet creates a service account as part of the deployment with the specified name: ```yaml theme={null} app: serviceAccount: name: custom-service-account create: true parquet: serviceAccount: name: custom-service-account create: true global: ... ``` The subsystems "app" and "parquet" run under the specified service account. The other subsystems run under the default service account. If the service account already exists on the cluster, set `create: false`: ```yaml theme={null} app: serviceAccount: name: custom-service-account create: false parquet: serviceAccount: name: custom-service-account create: false global: ... ``` You can specify service accounts on different subsystems such as app, parquet, console, and others: ```yaml theme={null} app: serviceAccount: name: custom-service-account create: true console: serviceAccount: name: custom-service-account create: true global: ... ``` The service accounts can be different between the subsystems: ```yaml theme={null} app: serviceAccount: name: custom-service-account create: false console: serviceAccount: name: another-custom-service-account create: true global: ... ``` ### External Redis ```yaml theme={null} redis: install: false global: redis: host: "" port: 6379 password: "" parameters: {} caCert: "" ``` To reference the `password` from a secret: ```console theme={null} kubectl create secret generic redis-secret --from-literal=redis-password=supersecret ``` Reference it in below configuration: ```yaml theme={null} redis: install: false global: redis: host: redis.example port: 9001 auth: enabled: true secret: redis-secret key: redis-password ``` ### LDAP LDAP configuration support in the current Helm chart is limited. Contact W\&B Support or your AISE for assistance configuring LDAP. Configure LDAP by setting environment variables in `global.extraEnv`: ```yaml theme={null} global: extraEnv: LDAP_ADDRESS: ldaps://ldap.company.example.com LDAP_BASE_DN: cn=accounts,dc=company,dc=example,dc=com LDAP_USER_BASE_DN: cn=users,cn=accounts,dc=company,dc=example,dc=com LDAP_GROUP_BASE_DN: cn=groups,cn=accounts,dc=company,dc=example,dc=com LDAP_BIND_DN: uid=ldapbind,cn=sysaccounts,cn=etc,dc=company,dc=example,dc=com LDAP_BIND_PW: ******************** LDAP_ATTRIBUTES: email=mail,name=cn LDAP_TLS_ENABLE: "true" LDAP_LOGIN: "true" LDAP_USER_OBJECT_CLASS: user LDAP_GROUP_OBJECT_CLASS: group ``` This legacy approach is no longer recommended. This section is provided for reference. **Without TLS** ```yaml theme={null} global: ldap: enabled: true # LDAP server address including "ldap://" or "ldaps://" host: # LDAP search base to use for finding users baseDN: # LDAP user to bind with (if not using anonymous bind) bindDN: # Secret name and key with LDAP password to bind with (if not using anonymous bind) bindPW: # LDAP attribute for email and group ID attribute names as comma separated string values. attributes: # LDAP group allow list groupAllowList: # Enable LDAP TLS tls: false ``` **With TLS** The LDAP TLS cert configuration requires a config map pre-created with the certificate content. To create the config map you can use the following command: ```console theme={null} kubectl create configmap ldap-tls-cert --from-file=certificate.crt ``` And use the config map in the YAML like the example below ```yaml theme={null} global: ldap: enabled: true # LDAP server address including "ldap://" or "ldaps://" host: # LDAP search base to use for finding users baseDN: # LDAP user to bind with (if not using anonymous bind) bindDN: # Secret name and key with LDAP password to bind with (if not using anonymous bind) bindPW: # LDAP attribute for email and group ID attribute names as comma separated string values. attributes: # LDAP group allow list groupAllowList: # Enable LDAP TLS tls: true # ConfigMap name and key with CA certificate for LDAP server tlsCert: configMap: name: "ldap-tls-cert" key: "certificate.crt" ``` ### OIDC SSO ```yaml theme={null} global: auth: sessionLengthHours: 720 oidc: clientId: "" secret: "" # Only include if your IdP requires it. authMethod: "" issuer: "" ``` `authMethod` is optional. ### SMTP ```yaml theme={null} global: email: smtp: host: "" port: 587 user: "" password: "" ``` ### Environment variables ```yaml theme={null} global: extraEnv: GLOBAL_ENV: "example" ``` ### Custom certificate authority `customCACerts` is a list and can take many certificates. Certificate authorities specified in `customCACerts` only apply to the W\&B Server application. ```yaml theme={null} global: customCACerts: - | -----BEGIN CERTIFICATE----- MIIBnDCCAUKgAwIBAg.....................fucMwCgYIKoZIzj0EAwIwLDEQ MA4GA1UEChMHSG9tZU.....................tZUxhYiBSb290IENBMB4XDTI0 MDQwMTA4MjgzMFoXDT.....................oNWYggsMo8O+0mWLYMAoGCCqG SM49BAMCA0gAMEUCIQ.....................hwuJgyQRaqMI149div72V2QIg P5GD+5I+02yEp58Cwxd5Bj2CvyQwTjTO4hiVl1Xd0M0= -----END CERTIFICATE----- - | -----BEGIN CERTIFICATE----- MIIBxTCCAWugAwIB.......................qaJcwCgYIKoZIzj0EAwIwLDEQ MA4GA1UEChMHSG9t.......................tZUxhYiBSb290IENBMB4XDTI0 MDQwMTA4MjgzMVoX.......................UK+moK4nZYvpNpqfvz/7m5wKU SAAwRQIhAIzXZMW4.......................E8UFqsCcILdXjAiA7iTluM0IU aIgJYVqKxXt25blH/VyBRzvNhViesfkNUQ== -----END CERTIFICATE----- ``` CA certificates can also be stored in a ConfigMap: ```yaml theme={null} global: caCertsConfigMap: custom-ca-certs ``` The ConfigMap must look like this: ```yaml theme={null} apiVersion: v1 kind: ConfigMap metadata: name: custom-ca-certs data: ca-cert1.crt: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ca-cert2.crt: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ``` If using a ConfigMap, each key in the ConfigMap must end with `.crt` (for example, `my-cert.crt` or `ca-cert1.crt`). This naming convention is required for `update-ca-certificates` to parse and add each certificate to the system CA store. ### Custom security context Each W\&B component supports custom security context configurations of the following form: ```yaml theme={null} pod: securityContext: runAsNonRoot: true runAsUser: 1001 runAsGroup: 0 fsGroup: 1001 fsGroupChangePolicy: Always seccompProfile: type: RuntimeDefault container: securityContext: capabilities: drop: - ALL readOnlyRootFilesystem: false allowPrivilegeEscalation: false ``` The only valid value for `runAsGroup:` is `0`. Any other value is an error. For example, to configure the application pod, add a section `app` to your configuration: ```yaml theme={null} global: ... app: pod: securityContext: runAsNonRoot: true runAsUser: 1001 runAsGroup: 0 fsGroup: 1001 fsGroupChangePolicy: Always seccompProfile: type: RuntimeDefault container: securityContext: capabilities: drop: - ALL readOnlyRootFilesystem: false allowPrivilegeEscalation: false ``` The same concept applies to `console`, `weave`, `weave-trace` and `parquet`. ## Configuration reference for W\&B Operator This section describes configuration options for W\&B Kubernetes operator (`wandb-controller-manager`). The operator receives its configuration in the form of a YAML file. By default, the W\&B Kubernetes operator does not need a configuration file. Create a configuration file if required. For example, you might need a configuration file to specify custom certificate authorities, deploy in an air gap environment and so forth. Find the full list of spec customization [in the Helm repository](https://github.com/wandb/helm-charts/blob/main/charts/operator/values.yaml). ### Custom CA A custom certificate authority (`customCACerts`), is a list and can take many certificates. Those certificate authorities when added only apply to the W\&B Kubernetes operator (`wandb-controller-manager`). ```yaml theme={null} customCACerts: - | -----BEGIN CERTIFICATE----- MIIBnDCCAUKgAwIBAg.....................fucMwCgYIKoZIzj0EAwIwLDEQ MA4GA1UEChMHSG9tZU.....................tZUxhYiBSb290IENBMB4XDTI0 MDQwMTA4MjgzMFoXDT.....................oNWYggsMo8O+0mWLYMAoGCCqG SM49BAMCA0gAMEUCIQ.....................hwuJgyQRaqMI149div72V2QIg P5GD+5I+02yEp58Cwxd5Bj2CvyQwTjTO4hiVl1Xd0M0= -----END CERTIFICATE----- - | -----BEGIN CERTIFICATE----- MIIBxTCCAWugAwIB.......................qaJcwCgYIKoZIzj0EAwIwLDEQ MA4GA1UEChMHSG9t.......................tZUxhYiBSb290IENBMB4XDTI0 MDQwMTA4MjgzMVoX.......................UK+moK4nZYvpNpqfvz/7m5wKU SAAwRQIhAIzXZMW4.......................E8UFqsCcILdXjAiA7iTluM0IU aIgJYVqKxXt25blH/VyBRzvNhViesfkNUQ== -----END CERTIFICATE----- ``` CA certificates can also be stored in a ConfigMap: ```yaml theme={null} caCertsConfigMap: custom-ca-certs ``` The ConfigMap must look like this: ```yaml theme={null} apiVersion: v1 kind: ConfigMap metadata: name: custom-ca-certs data: ca-cert1.crt: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ca-cert2.crt: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ``` Each key in the ConfigMap must end with `.crt` (for example, `my-cert.crt` or `ca-cert1.crt`). This naming convention is required for `update-ca-certificates` to parse and add each certificate to the system CA store. ## FAQ ### What is the purpose/role of each individual pod? * **`wandb-app`**: the core of W\&B, including the GraphQL API and frontend application. It powers most of our platform's functionality. * **`wandb-console`**: the administration console, accessed via `/console`. * **`wandb-otel`**: the OpenTelemetry agent, which collects metrics and logs from resources at the Kubernetes layer for display in the administration console. * **`wandb-prometheus`**: the Prometheus server, which captures metrics from various components for display in the administration console. * **`wandb-parquet`**: a backend microservice separate from the `wandb-app` pod that exports database data to object storage in Parquet format. * **`wandb-weave`**: another backend microservice that loads query tables in the UI and supports various core app features. * **`wandb-weave-trace`**: a framework for tracking, experimenting with, evaluating, deploying, and improving LLM-based applications.
