Question
Does container registry support image retention

- DigitalOcean Container Registry (DOCR)
Asked by robinAngler
Hello guys,
we just started using digital ocean container registry to store our images builded by our CI/CD pipeline. We build image on every push to repository for every branch, and then push the image to container registry. When we finish our work on some branch and merge the code to master, we also want to get rid of the images for that branch. I’m wondering, is there a way how to configure container registry to automatically delete images which are 2 days old does not match some patter like “master” for example? I was searching through the documentation but could not find anything related to it.
Thank you very much for your response

Hello!
We don’t currently offer retention policies and automatic deletion in DOCR, but that is on our roadmap.
You can list and delete images through the DigitalOcean API, so it would be possible to add automatic image deletion to your CI pipeline. Of course, you would still need to run garbage collection to reclaim space after deleting the images.
