Small Docker v2 registry auth server in Go.
It exists mostly as a project to learn Go, the Vagrant Docker provider, and to understand the protocol Portus implements.
- Authentication is only supported using htpasswd files
- Once authenticated, it provides push and pull access to the /$user namespace
Garita is inspired in Portus, which is a full featured auth server and registry index.
Garita uses HTTPS by default. If you want to run over plain http (eg. for development purposes) you need to pass the option -http. Then you don't need to supply --tlscert and --tlskey options.
garita --key path/to/server.key --htpasswd path/to/htpasswd --tlskey path/to/server.key --tlscert path/to/server.crt
You can pass a configuration file in toml format with -c or --config. Any other configuration from the command line overrides the configuration file.
At the same time you need to configure the registry
auth: token: realm: https://garita.yourdomain.com/v2/token service: registry.yourdomain.com issuer: garita.yourdomain.com rootcertbundle: /path/to/server.crt
If you use a self signed certificate, add the CA certificate to the system trusted anchors on the docker daemon host or add the certificate to:
The environment creates 3 containers:
- a Docker daemon (dockerd, dockerd.test.lan)
- a Registry (registry, registry.test.lan)
- garita (garita, garita.test.lan)
While the images are based on opensuse:13.2, the dockerd container requires a host kernel with overlayfs support. (eg. openSUSE Tumbleweed or another distribution supporting overlayfs). The dockerd container is already privileged but I don't want to mess with the loop devices of the host.
go install github.com/dmacvicar/garita
- Start the environment
vagrant up --no-parallel
- Everytime you rebuild
vagrant reload garita
- To see the logs
vagrant docker-logs -f garita
Run docker against the docker daemon running inside the container
docker -H tcp://localhost:23750 images
The typical testcase, pull busybox, tag it, and push it to the registry
docker -H tcp://localhost:23750 pull busybox docker -H tcp://localhost:23750 tag busybox registry.test.lan/duncan/busybox docker login registry.test.lan docker -H tcp://localhost:23750 push registry.test.lan/duncan/busybox
The specification does not go into every detail. If I missed something please open an issue.
