Hotfix 0.1.1#9
Conversation
Ensure that the non-root application user ($APP_UID) has full permissions to the published files in the final stage of the Docker image. - Add `chown -R $APP_UID:$APP_UID /app` prior to switching to the `$APP_UID` user.
📝 WalkthroughWalkthroughThe Dockerfile's final build stage adds a single RUN instruction that recursively changes ownership of the /app directory to $APP_UID:$APP_UID, placed before the existing USER and ENTRYPOINT instructions. ChangesDocker image ownership

COPY --chownoverRUN chown -Rto avoid layer bloat.The fix is functionally correct —
$APP_UIDis set by the aspnet base image, so ownership resolves as intended beforeUSER $APP_UID. However,RUN chown -Ron a directory already populated by a priorCOPYlayer causes the overlay filesystem to duplicate every file into a new layer, inflating the final image size (this is a well-documented Docker chown/COW pitfall). Setting ownership at copy time avoids the extra layer entirely.♻️ Proposed refactor

In `@Dockerfile` at line 14, The Dockerfile currently uses a separate ownership-changing step after copying files into /app, which causes unnecessary layer bloat. Update the image build flow to set ownership at copy time by using the COPY instruction with chown for the app contents, and remove the standalone RUN chown -R step.
