Adding CONTAINER_COMMANDS_ENABLE variable for container-shell to add support for allowing certain container commands for a specific container-shell invocation only.
Use case: Allow some people (via their SSH key) to only execute some but not all commands, e.g. container start and container-stop but not container create and container remove. Signed-off-by: Daniel Baumann <daniel.baumann@open-infrastructure.net>
