In the documentation, it seems that we can set the expire-in to several days or weeks. But I cannot decide an accurate fixed date. Is it possible to always keep the 'lastest' artifact, and remove the old one when a new one is successfully built?
Okey. I found a solution here :
With this help, it can be easily reached. The question should be closed.
Here's the instruction given by gitlab official.
Keeping the latest artifacts can use a large amount of storage space in projects with a lot of jobs or large artifacts. If the latest artifacts are not needed in a project, you can disable this behavior to save space:
- On the top bar, select Menu > Projects and find your project.
- On the left sidebar, select Settings > CI/CD.
- Expand Artifacts.
- Clear the Keep artifacts from most recent successful jobs checkbox.
You can disable this behavior for all projects on a self-managed instance in the instance’s CI/CD settings.
