github-workflows

This repository contains a collection of reusable github actions workflows to be used by Cloudkite's clients

  • build-and-push-image-to-acr.yml - Build and push docker image to Azure Container Registry
  • build-docker-push-to-acr.yml - Build and push docker image to Elastic Container Registry
  • commit-to-helm-chart-cronjobs.yml - Commit and push new image tag for a cronjob (standard-app.cronjobs.$CRONJOB_NAME.tag)
  • commit-to-helm-chart.yml - Commit and push new global image tag for the whole chart (standard-app.tag)

Google Cloud container delivery

gar-build-template.yml

Builds a caller's Docker context, pushes only the caller commit SHA to Google Artifact Registry, and returns the immutable image URI and sha256 digest. The workflow builds before Google authentication so the generated gha-creds-*.json file cannot enter the Docker build context. Callers should run their language-specific tests in a preceding job and pin this reusable workflow to an exact commit SHA.

If that commit-SHA tag already exists, a rerun reuses its digest rather than overwriting it. Configure GAR with immutable Docker tags to enforce this promotion contract at the registry boundary.

Required inputs are GCP_PROJECT, GAR_REPO_DOMAIN, GAR_REPO_PATH, SERVICE_ACCOUNT, and WORKLOAD_IDENTITY_PROVIDER. Optional inputs configure runner labels, Dockerfile, context, platform, and non-secret build arguments. PROJECT_ENV remains accepted only for caller compatibility; mutable environment tags are no longer published.

cloud-run-deploy-template.yml

Deploys an existing GAR image to a Cloud Run service. It accepts exactly one immutable digest or 40-character commit-SHA tag, resolves the final digest, optionally runs a Cloud Run migration job, deploys the same digest to the service, and verifies readiness. It never builds or pushes an image.

The called job enters GITHUB_ENVIRONMENT_NAME before resolving these GitHub environment variables:

  • GCP_APPLICATION_PROJECT
  • CLOUD_RUN_REGION
  • CLOUD_RUN_SERVICE
  • CLOUD_RUN_MIGRATION_JOB (optional)
  • GCP_WORKLOAD_IDENTITY_PROVIDER
  • GCP_DEPLOYER_SERVICE_ACCOUNT

Explicit workflow inputs can override those values. Set ROLLBACK: true with an exact IMAGE_DIGEST to skip migration and update only the service. Use GitHub environment protection rules for production approval.

Run ./tests/validate-gcp-delivery-workflows.sh after changing either workflow.
