Claim 10:
11. The method of claim 8, wherein:
a first performance of the container instantiation method comprises receiving the layer mount which provides access to the registry-resident form of the content of the layer identified in a first layer mount request without also providing access to all content of all of the layers that collectively constitute a first container image, creating a first union file system which spans the layers that collectively constitute the first container image, and launching a container-A process at a first instantiation location based on the first union file system;
a second performance of the container instantiation method comprises receiving the same layer mount which provides access to the same registry-resident form of the same content of the same layer identified in a second layer mount request without also providing access to all content of all of the layers that collectively constitute a second container image, creating a second union file system which spans the layers that collectively constitute the second container image, and launching a container-B process at a second instantiation location based on the second union file system;
wherein the first union file system is further characterized in that it is also based on a layer mount of a layer denoted here as layer-A that is not part of container-B, and wherein the second union file system is further characterized in that it is also based on a layer mount of a layer denoted here as layer-B that is not part of container-A;
thereby sharing a single instance of layer content between two containers while also furnishing each of the two containers with layer content that is not part of the other container.
