No permissions to delete /var/lib/postgresql/data

[daGrevis]

This is how I run Postgres container:

docker run -d \
           -v /etc/fxz/postgres:/var/lib/postgresql/data \
           -e LC_ALL=C.UTF-8 \
           -p 5432:5432 \
           --name=postgres \
           postgres

I can see created directory:

$ ls -l /etc/fxz/
drwx------ 15  999 root 4096 Nov 12 10:59 postgres

But the problem is that I have no permissions to delete it:

$ rm -rf /etc/fxz/postgres/
rm: cannot remove '/etc/fxz/postgres/': Permission denied

If I do it as root, it works.

Are there any way to delete it as non-root user? I am in docker group already.

The problem here arises from user permissions; the files in the mounted volume get chowned to the postgres user of the container by the entrypoint script (which happens to be 999) so that postgres can access the data. So, no there is no way to give your user permission to the files.

The hack is strong with this one.

docker run --rm -v /etc/fxz:/etc/fxz postgres /bin/bash -c 'rm -rf /etc/fxz/postgres'
