Container for Oracle 19.3.0 fails upon docker-compose up

[ArminBeda]

I have more than 24 GB of free memory:

docker info:

Still I receive this error message upon docker-compose up:

Any ideas?

Without the compose specification, it's going to be hard to tell for sure, but I suspect you're mounting /opt/oracle/oradata to a directory on a Linux system, and permissions are not correct on the directory. The mounted filesystem/directory must be owned by the oinstall (or 54321) group or oracle (or 54321) user, else the oracle process running inside the container cannot mkdir -p /opt/oracle/oradata/ORCLCDB (or any other files).

I have a free chapter available here that covers persistence that may help further.
