With this PR, we introduce the concept of image handlers. They support walking a tree of image resource descriptors for doing various tasks related to processing them. Handlers can be dispatched sequentially or in parallel and can be stacked for various effects. The main functionality we introduce here is parameterized fetch without coupling format resolution to the process itself. Two important handlers, `remotes.FetchHandler` and `image.ChildrenHandler` can be composed to implement recursive fetch with full status reporting. The approach can also be modified to filter based on platform or other constraints, unlocking a lot of possibilities. This also includes some light refactoring in the fetch command, in preparation for submission of end to end pull. Signed-off-by: Stephen J Day <stephen.day@docker.com> |
