Canceling jobs does not stop containers #4
Description
Currently, canceling jobs via mlex_utils does not properly stop the associated Docker/Podman containers. This is because mlex_utils cancels the flow run itself, but the containers are launched from within a bash script. As a result, stopping the main process does not propagate to the child Docker/Podman processes, which continue running in the background.
Expected behavior: Canceling a job should also stop any containers it started.
Potential solutions:
- Implement a cleanup routine that explicitly stops the containers when the job is canceled.
- Consider launching containers in a way that ties their lifecycle more directly to the parent process.
