Deploy to Cloud Build

This document describes how to use GCR Cleaner in Cloud Build with Artifact Registry

1. Grant a role roles/artifactregistry.repoAdmin to the Cloud Build service account because it need artifactregistry.repositories.deleteArtifacts permission.

2. Export your project ID as an environment variable.

   export PROJECT_ID="my-project"

3. Create a YAML file named cloudbuild.yaml which will always keep three images:

   steps:
     - name: asia-docker.pkg.dev/gcr-cleaner/gcr-cleaner/gcr-cleaner-cli:latest
       args:
         - -repo
         - "asia-docker.pkg.dev/my-project/my-repo/my-image"
         - -keep
         - "3"
         - -tag-filter-any
         - ".*"

4. Manual trigger Cloud Build using gcloud CLI to check it:

   gcloud builds submit \
     --project "${PROJECT_ID}" \
     --config cloudbuild.yaml .
