Client-aware container image optimization

Abstract

Mechanisms are provided that provide a container image to a client computing device. The mechanisms receive, from a client computing device, a pull request for a requested container image. The pull request comprises a specification of cached container layers that are stored in a local container layer store of the client computing device. The mechanisms determine, based on the specification of the cached container layers, a set of one or more of the cached container layers that can be reused to provide the container image at the client computing device, thereby generating a set of reuse container layers. The mechanisms generate, based on the determination, an output container image comprising only container layers, of the requested container image, that provide files not provided by the set of reuse container layers. The mechanisms transmit the output container image to the client computing device.
