Fix renamed apps keeping stale built image tags - #2464
Conversation
Rewrite CapRover-built image names when an app is renamed so a new app with the old name cannot overwrite the shared tag. Fixes caprover#2211
📝 WalkthroughWalkthroughChangesApplication Rename Image Migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Renamed apps using legacy image naming may retain stale image tags, potentially causing the wrong image to run after the old app name is reused; push failures may also surface as unclassified API errors. The change is otherwise bounded and mergeable with explicit follow-up on these issues. Sequence Diagram(s)sequenceDiagram

Preserve legacy double-hyphen image names during app renames.
CapRover previously used img-<namespace>--<appName>. rewriteCapRoverBuiltImageName only matches img-<namespace>-<appName>, so legacy deployedImageName values are not renamed. Support both repository forms.

Thank you for digging into this and for adding thorough test coverage. I agree that #2211 describes a real bug, and this PR addresses the reported scenario. My concern is proportionality. Triggering the problem requires renaming a deployed app, reusing its old name, deploying another image under that name, and later rescheduling the renamed app. The proposed fix makes every rename migrate historical images, potentially pull and push them through a registry, and rewrite the stored deployment history. That adds several operational failure modes and a meaningful long-term maintenance cost to a rarely used path. It feels a little like taking an excavator to plant a tiny flower. I would prefer a narrower solution, such as preventing reuse of an image repository that is still referenced by another app. Another - imperfect but good enough - solution is to just retag the latest image with a local reference, and purge all the deployment history - when renaming an app. I’d like to decline this implementation and explore that smaller approach. I genuinely appreciate the work here, especially since the underlying issue is valid. |
