Standard image capabilities

[lucernae]

In order to support container-based deployment, we would like to have certain scripts that provides these capabilities to the GeoNode docker image:

• Microservice-based. The image should do one thing only, which is to run GeoNode either in Django mode or Celery mode
  • The official image does too much (it includes cron and memcached). So this implies we have to cut those responsibilities
• The GeoNode image should be able to run GeoNode code and there are 3 use cases. These use cases must be supported by
  entrypoint scripts, or as ready-to-use scripts in the image.
  • As Django service run using uwsgi or manage.py server
  • As Celery service running as worker or scheduler (beat)
  • As Django management command runner (ad hoc command or cron-based job)
• Application logs must go into stdout/stderr of the container, not to file
• Support for rootless container
• Support for randomized superadmin credentials (if superadmin credentials were not supplied)
