I’ve no problem with the same docker-comppose.yml file  
Who’s the user that runs your ‘docker-compose up’ command? Did you followed the docker-ce post installation steps [here](https://docs.docker.com/install/linux/linux-postinstall/) to “Manage Docker as a non-root user”

I was running the docker-compose up command as a non-root user.

> sudo docker-compose up

The security warnings listed in the docker-ce post installation steps made me not want to add the non-root user to the docker group.

I went and added the non-root user to the docker group, as instructed in the post-installation doc.

> sudo usermod -aG docker $USER

Same errors.

If I comment-out the “user: root” lines in the docker-compose file, the errors change to  
django.db.utils.OperationalError: FATAL: role “awx” does not exist
