Bitbucket Runner Autoscaler

This module deploys a Helm chart for the Bitbucket runner autoscaler and supports deploying Bitbucket runner groups, as well as the AWS IAM components needed for Bitbucket runners to authenticate against AWS resources.

Deployment methods

Helm

Deploy Helm chart via Helm resource (default method, set enabled = true)

Argo Kubernetes

Deploy Helm chart as ArgoCD Application via Kubernetes manifest resource (set enabled = true and argo_enabled = true)

Warning

When deploying with ArgoCD application, Kubernetes terraform provider requires access to Kubernetes cluster API during plan time. This introduces potential issue when you want to deploy the cluster with this addon at the same time, during the same Terraform run.

To overcome this issue, the module deploys the ArgoCD application object using the Helm provider, which does not require API access during plan. If you want to deploy the application using this workaround, you can set the argo_helm_enabled variable to true.

Argo Helm

Deploy Helm chart as ArgoCD Application via Helm resource (set enabled = true, argo_enabled = true and argo_helm_enabled = true)

Examples

See basic example for further information. Refer to the IAM example for guidance on creating an assume role policy for IAM roles with a more limited scope.
