Some points for discussion:

• At 2 places in the compute worker code logger.debug(...) is used withtout checking if LOG_LEVEL is set to debug. Should this be fixed?
• Do you think the following 3 constants are ok to be placed in the new Settings class or should they be placed somewhere else?

 # Constants
  DOCKER = "docker"
  PODMAN = "podman"
  LOG_LEVEL_DEBUG = "debug"
