Migration to Github Container Registry

How to migrate your images from gcr.io to ghcr.io and why we migrated
By Stanislav Jakuschevskij, IBM |

Why and How

Dear Tekton users and contributors, to reduce costs, we’ve migrated all our releases to the free tier on ghcr.io/tektoncd.

All new Tekton releases are exclusively on ghcr.io/tektoncd. Old releases are also now available on ghcr.io/tektoncd.

Please migrate your old releases to ghcr.io immediately since we have limited funding to allocate to gcr.io egress.

To migrate you need to replace gcr.io/tekton-releases with ghcr.io/tektoncd in all your images. e.g.

# old
gcr.io/tekton-releases/github/tektoncd/pipeline/cmd/entrypoint:v0.9.2

# new
ghcr.io/tektoncd/github.com/tektoncd/pipeline/cmd/entrypoint:v0.9.2

You could run:

sed -e 's,gcr.io/tekton-releases,ghcr.io/tektoncd,g'

End of Life Releases

We started enforcing the download of Tekton images from ghcr.io.

Here are the details of what changed:

  • Tekton LTS releases originally released to gcr.io will remain available on gcr.io until the EOL date.
  • The same images are available on ghcr.io, so we ask users to please update their manifests and download images from ghcr.io to save egress bandwidth costs.
  • Any EOL Tekton release will only be available on ghcr.io.
  • Images on gcr.io will be removed from public access over the next few days.
  • New releases will only be made on ghcr.io, so no action is required.
