Deployment of updated services or layers on demand through containers

A computer system comprising:

• at least one computing device;
• a set of one or more computer-readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer-readable storage media, for causing the at least one computing device to perform computer operations to automatically generate and deploy applications on-demand through container images, the computer operations including:
• obtaining a first container comprising image layers, wherein the image layers include a base image layer and one or more image layers;
• generating dependencies between the image layers, wherein the dependencies comprise, for each layer of the one or more layers, a submissive sequence and a dependent sequence, wherein the submissive sequence for each layer is based on determining if at least one layer of the one or more layers was committed after the layer, and wherein the dependent sequence for each layer is based on based on determining if at least one layer of the one or more layers modifies a common file with the layer;
• obtaining a request for an application, wherein at least one image layer of the one or more image layers comprises features of the application;
• identifying based on the dependencies, at least one additional image layer related to the at least one image layer;
• and
• generating and deploying a second container, wherein image layers of the second container consist of the at least one image layer, the at least one additional image layer related to the at least one image layer, and the base layer.
