  • @typhoon@fosstodon.org

• Deprecate publishing to the Terraform Module Registry
  • Typhoon docs have always shown using Git-based module sources, not the Terraform Module Registry
  • Module usage should be source = "git::https://github.com/poseidon/typhoon/... not source = poseidon/kubernetes/...
  • Terraform's Module Registry requires subtree mirroring typhoon to special terraform-platform-kubernetes repos, only supports release versions (no commit SHAs or forks), only ever contained Flatcar Linux modules (not Fedora CoreOS) for historical reasons
  • Note, this does not affect Terraform Providers like poseidon/matchbox or poseidon/ct, the registry works well for providers
