container-config-file

#!/bin/bash

# -----------------------------------------------------------------------------
# This script extracts the path of the devcontainer config-file from
# docker-events.
#
# This helps in identifying who has started a container if the container-name
# does not itself include any indication.
#
# This can be used to determine if a container can be safely stopped/removed
#
# It takes one argument: The container-name
