Retention/expiration policy for container images
Pushing images from CI is great, but after a while, those images are going to take up a lot of space and never be referenced again. We need a project level retention policy for automatically pushed images. e.g. "store not more than 30 images for master branch and delete after 2 weeks". We also need reasonable defaults so GitLab.com and self-managed instances behave nicely.
- Keep tagged images longer? Differentiate SHA-type tags and branch tags from release-type tags, like
- Keep 3-5 recent ones longer?
- Also expire after time
- Differentiate default policy on subscriptions?
