The docker GUI tool Kitematic has a panel which allows changing environmental variables for a running container. Upon change (and save), the container restarts with the environmental variables changed.
Is there a way to do this via a command line tool to do the same on a remote server?
I know that the containers can be deleted and re-run with new environmental variables, but that doesn't preserve the contents.
I have other containers which do DNS proxying via the variables, but I'm trying to not recreate a slow starting container.
