From 9b8f4ba8d31febfdfb9fcb75b15c2b6f4d575fde Mon Sep 17 00:00:00 2001 From: Daniel Baumann Date: Tue, 27 Jun 2017 09:54:18 +0200 Subject: 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.
