Description

When deploying the Docker stack, the status is displayed as "Exited" because one of the containers, which is designed to run only once during startup (e.g., a migration job), is not running.
This PR adds a check to list exited containers, and verify if they exited with error code 0 (OK) or something else (NOT OK)
