How to Give A Postgres User SuperUser Privilege Through docker-compose?

This is my docker-compose file section for postgres container. These settings are fine, but my django app requires this user to have superuser privileges through this command inside postgresql.

ALTER ROLE project_admin SUPERUSER;

How can this be accomodated inside this docker-compose file?

 db:
  image: postgres:latest
  container_name: project-db
  environment:
   - POSTGRES_USER='project_admin'
   - POSTGRES_PASS='projectpass'
   - POSTGRES_DB='project'
Solution

  • You need to save your command as a script say ./scripts/01_users.sql:

    ALTER ROLE project_admin SUPERUSER;

    Then your docker-compose:

    ...
 db:
  image: postgres:latest
  container_name: project-db
  environment:
   - POSTGRES_USER='project_admin'
   - POSTGRES_PASS='projectpass'
   - POSTGRES_DB='project'
  volumes:
   - ./scripts/:/docker-entrypoint-initdb.d/

    This will run the script at startup and alter your user's privileges.
