The registry plugin accepted `registry:set <app> image-repo-template <value>` and persisted the per-app file, but only ever read the global value when rendering the image repository, so per-app overrides were silently dropped. The property now follows the same per-app to global to default fallback chain used by `push-on-release` and `server`, and `registry:report` exposes the raw per-app value alongside the existing global and computed flags. The `push-extra-tags` report flags were extended for the same reason: the runtime already honored per-app and global values, but the report only surfaced the raw per-app entry.
- Replace boolean return values with proper error handling in dockerTag and dockerPush functions
- Add detailed error context including Docker command exit codes and stderr output
- Remove TODO comments and improve error messages for better debugging
- Fix error message formatting in defer function
This addresses the TODO comments for better error handling and provides
users with actionable error information when Docker registry operations fail.
Closes: #XXXX
When upgrading from an older install of Dokku with the old community registry plugin, newlines could be available in the properties set on disk. Trim them so any usage of the properties continues to work as expected by users.
This changes restarts to drop the 'release' part that currently gets triggered, which also helps reduce the possibility that a new image layer will be added due to predeploy deploy triggers.
Note that the old method essentially halfway-rebuilt the app (which was what added the extra layer). This refactor removes that, which is a bc-break.
Additionally, scaling processes will result in deploying _only_ restarting the processes being scaled.
Closes#2184
