Weights & Biases AWS Module

IMPORTANT: You are viewing a beta version of the official module to install Weights & Biases. This new version is incompatible with earlier versions, and it is not currently meant for production use. Please contact your Customer Success Manager for details before using.

This is a Terraform module for provisioning a Weights & Biases Cluster on AWS. Weights & Biases Local is our self-hosted distribution of wandb.ai. It offers enterprises a private instance of the Weights & Biases application, with no resource limits and with additional enterprise-grade architectural features like audit logging and SAML single sign-on.

About This Module

Pre-requisites

This module is intended to run in an AWS account with minimal preparation, however it does have the following pre-requisites:

Terrafom version >= 1

Credentials / Permissions

AWS Services Used

• 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 Loadbalancing (ALB)
• Amazon Secrets Manager

Public Hosted Zone

If you are managing DNS via AWS Route53 the hosted zone entry is created automatically as part of your domain management.

If you're managing DNS outside of Route53, you will need to:

1. Create a Route53 zone name {subdomain}.{domain} (e.g test.wandb.ai)
2. Create a NS record in your parent system and point it to the newly created Route53
3. Enable the external_dns option in this module

You can learn more about creating a hosted zone for a subdomain, which you will need to do for the subdomain you are planning to use for your Weights & Biases installation. To create this hosted zone with Terraform, use the aws_route53_zone resource.

ACM Certificate

While this is not required, it is recommend to already have an existing ACM certification. Certificate validation can take up two hours, causing timeouts during module apply if the cert is generated as one of the resources contained in the module.

How to Use This Module

• Ensure account meets module pre-requisites from above.

• Please note that while some resources are individually and uniquely tagged, all common tags are expected to be configured within the AWS provider as shown in the example code snippet below.

• Create a Terraform configuration that pulls in this module and specifies values of the required variables:

provider "aws" {
  region = "<your AWS region>"
  default_tags {
    tags = var.common_tags
  }
}

module "wandb" {
  source    = "<filepath to cloned module directory>"
  namespace = "<prefix for naming AWS resources>"
}

• Run terraform init and terraform apply

Examples

We have included documentation and reference examples for additional common installation scenarios for Weights & Biases, as well as examples for supporting resources that lack official modules.

• Private Access Only
• Private Existing Network
• Public External DNS
• Public Route 53 DNS

A note on updating EKS cluster version

Users can update the EKS cluster version to the latest version offered by AWS. This can be done using the environment variable eks_cluster_version. Note that, cluster and nodegroup version updates can only be done in increments of one version at a time. For example, if your current cluster version is 1.21 and the latest version available is 1.25 - you'd need to:

1. update the cluster version in the app_eks module from 1.21 to 1.22
2. run terraform apply
3. update the cluster version to 1.23
4. run terraform apply
5. update the cluster version to 1.24 ...and so on and so forth.

Upgrades must be executed in step-wise fashion from one version to the next. You cannot skip versions when upgrading EKS.
