US Patent 11934811 Container image building using dependency container images

Container image building using dependency container images. First dependency information that identifies a first set of dependencies necessary to generate a first application container image is accessed. A dependency container image index that identifies dependencies contained in one or more dependency container images is accessed. A first dependency container image of the one or more dependency container images is selected based on the dependency container image index and the first dependency information. The first dependency container image lacks at least one dependency identified in the first set of dependencies. A new dependency container image is generated using the first dependency container image and the at least one dependency. A new entry is stored in the dependency container image index that identifies the new dependency container image and each dependency contained in the new dependency container image.
