docker run --name registry-browser -it -p 8080:8080 -e DOCKER_REGISTRY_URL=http://your-registry:5000 klausmeyer/docker-registry-browser

Manual setup

  1. Install ruby e.g. using RVM (see .ruby-version file for required version).
  2. Execute gem install bundler && bundle install --without development test inside your local clone of this repository
  3. Run the application using DOCKER_REGISTRY_URL=http://your-registry:5000 bundle exec bundle exec puma -C config/puma.rb


The configuration is done by environment variables.

Option Required Type Example Description
DOCKER_REGISTRY_URL yes String http://your-registry:5000 URL to the Docker Registry which should be browsed
NO_SSL_VERIFICATION no Bool true Enable to skip SSL verification (default false)
BASIC_AUTH_USER no String joe Username for basic-auth against registry
BASIC_AUTH_PASSWORD no String supersecretpassw0rd Password for basic-auth against registry
ENABLE_DELETE_IMAGES no Bool true Allow deletion of tags (default false)
PUBLIC_REGISTRY_URL no String your-registry:5000 The public URL to the Docker Registry to do docker pull

You can also set BASIC_AUTH_USER and BASIC_AUTH_PASSWORD as Docker Swarm secrets.


If you're using a reverse-proxy setup with SSL termination in front of this application in combination with ENABLE_DELETE_IMAGES=true you must make sure that the application knows about this fact (by sending X-Forwarded-Proto: https in the HTTP headers). Otherwise the application would throw errors like "HTTP Origin header [...] didn't match request.base_url [...]" when you're trying to delete image-tags.
