Copy link

Container failed to start when running as non-root (user 1000:1000) because copied directories had restrictive 770 permissions, likely due to different umask in persistent BuildKit. Non-root users couldn't access /usr/lib to load required dynamic libraries.

Adds --chmod=755 to all COPY commands to explicitly set permissions and improves library extraction with robust lddtree processing. Also fixes workflow syntax error and removes docker/** from paths-ignore to ensure Docker changes trigger CI builds.

Copy link

It was fun resolving this permission issue... COPY --chmod in Docker apparently only modifies the files, not the directories, so I've added a little prepper stage between the builder and the scratch output so it can organise the files into "layers" and set the mode correctly before copying the layers into the final scratch for export.

I can confirm this has resolved the permissions issue for me, either way!
