uid and gid mismatch when using 'ADD --chown' in Dockerfile #36349
Description
Description
Using ADD --chown results in files being owned by some other uid/gid than provided in chown.
Steps to reproduce the issue:
- Use ADD with --chown flag in Dockerfile:
ADD --chown=www-data:www-data build_artifact.tar.gz /var/www RUN chown www-data:www-data /var/www- Build image from this Dockerfile
- Create and run container from built image
- Run
ls -la /var/www/
Describe the results you received:
Files and directories owned by uid 1001 and gid 1002. Both uid and gid is not assigned to any user in container and host machine. What's interesting, /var/www (.) is owned by www-data:www-data.
drwxr-xr-x 1 www-data www-data 6 Feb 19 10:32 .
drwxr-xr-x 1 root root 16 Jan 22 09:40 ..
drwxr-xr-x 3 1001 1002 4096 Feb 12 11:35 .ebextensions
-rw-r--r-- 1 1001 1002 722 Feb 19 10:31 .env
Describe the results you expected:
Files and directories are owned by provider www-data user:
drwxr-xr-x 1 www-data www-data 6 Feb 19 10:32 .
drwxr-xr-x 1 root root 16 Jan 22 09:40 ..
drwxr-xr-x 3 www-data www-data 4096 Feb 12 11:35 .ebextensions
-rw-r--r-- 1 www-data www-data 722 Feb 19 10:31 .env

Reformat the filesystem with ftype=1 to enable d_type support.
Running without d_type support will not be supported in future releases.
