If some real issue occurs with ceph, the fix would probably not be found inside the docker configuration. All my initial problems were caused by my own stupidity and not following the manuals correctly. If you know the difference between an image and a container, you know how to pull an updated image and you know how get information about images and containers. You're good to go. It won't hurt to know more. It's always the case that troubleshooting becomes easier with the augmentation of knowledge and experience. But remember. You can't know it all! That's the reason of existence of this mailing list, right? Your argumentation referencing the managing of vm's and snapshots isn't valid => you assume us readers know about managing vm's and snapshots...
