  --service=NAME                            Name of the service for which to print logs, eg. haf, hivemind-server,
                                            hafah-postgrest-1; if empty print logs for all the services (default: empty string)
  --tail=NUMBER                             Number of last lines of the log to print per service, if empty print all (default: empty string)
  --since=TIMESTAMP or RELATIVE             Show logs since timestamp  (e.g. 2013-01-02T13:23:37Z) or relative (e.g. 42m for
                                            42 minutes) (default: empty string)
  --until=TIMESTAMP or RELATIVE             Show logs before a timestamp (e.g. 2013-01-02T13:23:37Z) or relative (e.g. 42m for
                                            42 minutes) (default: empty string)
  --timestamps                              Show timestamps
  --no-color                                Print logs without color (useful if redirecting to file)
  --profiles=P1,P2,P3                       Profile(s) to use, must be the same as when the stack was started
  --project-name=NAME                       Name of the Compose project, must be the same as when the stack was started
                                            (default: defined at the top of stack/compose.yml)
  --env-files=1.env,2.env                   Specify a file to use to start the stack, uses ${SRC_DIR}/stack/.env 
                                            when empty, must be the same as when the stack was started (default: empty)
