Change required for newer installations
by adlerweb, February 28, 2021

Small and easy to use plugin to give a generic overview over a docker system without requiring any additional dependencies besides bash and docker. For newer docker installations line 13 must be changed to avoid spurious warnings: mkdir -p /tmp/.docker ; touch /tmp/.docker/config.json
