[FR] Formally deprecate gcr.io/cloud-builders/go

[nathanperkins]

Detailed Feature Information

Which builder is relevant to this request?

gcr.io/cloud-builders/go

Is your feature request related to a problem? Please describe.

Yes, the latest go builder image available is 1.22, which is unsupported since 2025-02-04. It should not be used to build anything due to CVEs.

The current version of golang is 1.25.3 and the oldest supported minor version is 1.24.9, so the cloud-builders images are 2-3 versions behind.

Describe the solution you'd like

Formally deprecate gcr.io/cloud-builders/go images and recommend the use of the official golang image from Docker Hub.

• GCP's own docs for Build and test Go applications use the official golang image.
• Having these obsolete / insecure images around only contributes to confusion and security issues in the ecosystem.
• Endlessly building these images also wastes resources if they provide no value beyond the official image.

Describe alternatives you've considered

Update the script to build the current supported versions and remove the old unsupported versions.

However, there were attempts to update the version to 1.23 a year ago in #1029, but there was no response.
