What resources are you concerned about being consumed? - There will only ever be one running kernel with docker. - The base filesystem layer, if identically hashed, will be shared as an overlay filesystem. - The memory footprint of whatever each container runs (which will generally not be a full from runlevel0 system) will not be shared, except in the sense that binaries loaded into ram from the same overlay filesystem will have some of their disk pages shared.
