roryqi opened a new pull request, #11533: URL: https://github.com/apache/gravitino/pull/11533
### What changes were proposed in this pull request? Replace the post-COPY `RUN chmod -R g+rwX <dir>` step with `COPY --chmod=775` in three Dockerfiles: - `dev/docker/gravitino/Dockerfile` - `dev/docker/iceberg-rest-server/Dockerfile` - `dev/docker/lance-rest-server/Dockerfile` ### Why are the changes needed? `chmod -R` after `COPY` rewrites the mode of every file. With OverlayFS each modified file is copied up into the `RUN` layer, so the whole application tree (~1.9GB for the gravitino image) is stored twice, roughly doubling the image size. `COPY --chmod` sets the mode as the files are written, so there is only one copy. Measured on the gravitino image (`docker history`): | layer | before | after | |-------|--------|-------| | COPY app tree | 1.89 GB | 1.89 GB | | permission step | `chmod -R` = **1.89 GB** | `chmod +x`+`useradd` = **369 kB** | Fix: #11532 ### Does this PR introduce _any_ user-facing change? No API change. Published Docker images are ~1.9GB smaller. Note: files are now mode 775 instead of the previous `g+rwX` (which preserved existing execute bits); this only adds the execute bit to regular files and does not affect runtime behavior. ### How was this patch tested? Built the fixed image and verified with `docker history` that the duplicate ~1.9GB chmod layer is gone (replaced by a 369kB permission layer). Ran the image as the non-root user (uid 1000): the server starts and serves the Gravitino REST (`/api/version`, metalake CRUD), Iceberg REST (`/iceberg/v1/config`) and Lance REST endpoints successfully. 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
