描述

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

研究方向
The issue requires modifying the `st2ctl` script to detect when it is running in a Docker environment (e.g., by checking for the presence of `/.dockerenv` or the container environment variable). Once detected, the tool should output Docker specific commands (e.g., `docker ps`, `docker restart`) instead of attempting to manage services via system commands like `supervisorctl`. The contributor should examine the current `st2ctl` script (likely a shell script in the repository) to understand how it handles process management and then add a conditional block for Docker. There are no existing PRs or comments to reference.
