Docker-compose mount postgress database for tests
I'm trying to put together a compose file for my development environment, but I'm having problems finding some convinient way to setup a database filled with test data. I tried mounting directory from my project as a data folder for postgres container, but it mounts as root and postgres throws:
data directory “/var/lib/postgresql/data/pgdata” has wrong ownership
Named volume works, but it would be problematic to use it with a git repo.
I could also just copy data directly into a docker image, but then I'd have to rebuild it whenever data changes.
Is there any other way around this?

Change the owner/group of the file (chown)?

@ChrisStryczynski I created Dockerfile for postgres and addedRUN mkdir -p "$PGDATA" && chown postgres "$PGDATA"(PGDATA set to/var/lib/postgresql/data) I still getFATAL: data directory "/var/lib/postgresql/data" has wrong ownershipI guess ownership changes when compose mounts volume.

You need to do the chown on the directory you mount - not the directory within the container (dockerfile). The mounted directory overrides whatever is in the container.

You'll need to determine the userid of the postgresql user, this can be done with id -u postgres (within the container).
Replace 1234 with the id you get from the above.
Then on the volume that you mount, from the host you need to do chown -R 1234:1234 path/to/volume/that/you/are/mounting.

Not possible since container is stopped after fatal is rised. I could theorethically write bash script to switch ownership and use it as entrypoint, but thats starting to get messy.
