This cli-tool lets you query your private docker registry for different things and delete them. **docker_registry_cli is yet build/tested on osx only **

1. List/Delete images and/or tags
2. Supports Basic Auth and Bearer Token Auth which are used by projects like Docker-Auth or Portus
3. Supports credential helper (preferred) and config.json auth (plain text auth, so will be removed in the future)

gem install docker_registry_cli

For help see

docker_registry_cli --help

List all repositories:

docker_registry_cli delete_image someimage

To ease up your usage, you can add some configuration

1. If you did yet not do so (you will have..), login into your registry using your local docker. docker login <yourdomain> This creates a ~/.docker/config.json. From docker 1.11 it will be automatically using the credential helper:

In any way you should always use the credential helper, see here

Be aware, unless you use a credentials helper, your user/password is saved plain-text!

Alternatively (not recommended): Provide user and password on each cli call

2. optionally, define a default domain echo "domain: <yourdomain>\n" > ~/.docker_registry.yml This defines the default domain to query for

Deleting images

If you want to delete images, be sure to enable storage->delete->true in your registry-installation config.yml, see https://github.com/docker/distribution/blob/master/docs/configuration.md

• HTTPS only (i consider HTTP to be a bug)
