  • Registry -- the API/service you talk to to push/pull images
  • Repository -- a set of relate container images that share the same name but different tags.
  • Container Image -- a single image that can be used to launch a container. Has multiple "names"
  • Container Image Layer -- implementation detail used to speed up image push/pull/launch
