hocker (hackage): hocker is a suite of command line utilities and a library for:  fetching a docker image  fetching a layer of an image  fetching an image's configuration  fetching a docker registry image manifest  generating nix build instructions from a registry image manifest  The motivation for this tool came from a need to fetch docker image artifacts from a docker registry without the stock docker tooling that is designed to only work with the docker daemon.  These tools only work with version 2 of the docker registry and docker version (>=) 1.10.  For a complete set of usage examples please see the project's README.md.
