This change adds support for specifying an initial version to use when a release channel is being used. The new logic sets the min_master_version variable to the value of the locally defined master_version when release_channel is null or "UNSPECIFIED". When a release channel is specified, min_master_version is set to the value of kubernetes_version if it is defined, and falls back to the value of master_version otherwise.

Fixes #1460

This change adds support for specifying an initial version to use when a release channel is being used.
The new logic sets the `min_master_version` variable to the value of the
locally defined `master_version` when `release_channel` is `null` or `"UNSPECIFIED"`.
When a release channel is specified, `min_master_version` is set to the value of `initial_version`
if it is defined, and falls back to the value of `master_version` otherwise.

Thanks for the contribution @slimatic!

If we don't have one already, please include one of the test fixtures setting kubernetes_version = "latest" so this new functionally is covered by the Integration tests.

Thanks @slimatic, I'll re-run the CI. Per merge timeline, what are the potential impacts to existing clusters? Just need to determine if this is OK for immediate minor release now, or if it will need to be a major release with migration documentation.

@apeabody were the following questions were directed to me?

  • "Per merge timeline, what are the potential impacts to existing clusters? "
  • "OK for immediate minor release now, or if it will need to be a major release "

Hi @slimatic - Thanks, yes, do you have any insight on the potential impacts to existing clusters?

Hi @slimatic - Thanks, yes, do you have any insight on the potential impacts to existing clusters?

Yes, based on my tests, making this change will have minimal impact on existing clusters. If the Kubernetes version is modified and applied to an existing cluster, Terraform will upgrade the cluster only if the specified version is greater than the current version. If the version is smaller than the existing version, the terraform apply command will complete successfully without upgrading the cluster version.

Thanks @slimatic and @apeabody. I did a quick test to validate and observed similar behavior as noted by @slimatic so it looks okay to release as minor.
