$ make devcluster
This command creates a kraken-agent image containing an agent binary and a kraken-herd image containing build-index, origin, proxy, and tracker binaries.
It starts 2 agent docker containers and 1 herd container. Docker-for-Mac is required for devcluster to work, because the development config files use host.docker.internal for address of all components.
A simple registry storage backend is provided for read-only access to Docker registry. A library image can be pulled from agent.
$ docker pull localhost:16000/library/golang:1.14
Note, this backend is used for all library/.* repositories. library is the default namespace for Docker Hub's standard public repositories.
For all the other repositories, a testfs storage backend is included in the kraken-herd image, which is a simple http server that supports file uploading and downloading via port 14000. Testfs simply stores blobs and tags on filesystem.
A test image can be pushed to the herd instance
$ docker push localhost:15000/<repo>:<tag>
Pull the test image from agent:
$ docker pull localhost:16000/<repo>:<tag>
