Description

st2ctl assumes it's running in a VM environment and wasn't designed to be executed inside the Docker. We'll need to improve that.

Because listing processes or starting services is not viable in a Docker environment, where each service runs in its own Docker container, st2ctl needs a simple modification so it doesn't try to query list of processes but instead suggest to use Docker cmd.

Example commands which don't work in Docker environment:

  • st2ctl status
  • st2ctl stop
  • st2ctl start
  • st2ctl restart
  • st2ctl restart-component
  • st2ctl reopen-log-files
  • st2ctl reload lists running processes as well

Contributor guide

Research direction
Examine the st2ctl script's process management logic and add a check for Docker environment to use Docker CLI commands instead.
