    # docker compose run redirects the stderr of any invoked executables to
    # stdout. The only messages that will appear on stderr are issued by
    # docker compose run itself. This appears to be an undocumented "feature":
    # https://docs.docker.com/engine/reference/commandline/compose_run/
    #
    # The "2>/dev/null" below silences the messages from docker compose run.
    # For example, the output like the following will not be visible:
    #     [+] Creating 2/0
    #      ✔ Container cc-wordpress-db  Running                          0.0s
    #      ✔ Container cc-web           Running                          0.0s
