Remove SGBD from image

[AR2000AR]

SGBDs like postrgesql should not be in the server image. They should be hosted in a other container. This is usually done with a docker-compose file. This would reduce the image size, and allow sys admins to reuse a existing server while giving the main image non admin credentials.

Hello @AR2000AR. Many users use the embedded database, so we don't plan to remove it from the image. But you can use a separate database, example docker-compose.yml.
