Foreman Docker Plugin

This plugin has been discontinued. The latest release only helps with its removal. If you're interested in taking over the maintanance, let us know.

In order to remove the plugin from you Foreman installation, following steps need to be taken

  1. make a backup
  2. upgrade to last version of foreman-docker 5.0 (and Katello if you're using it)
  3. run foreman-rake db:migrate (if you have Katello, this will erase docker data)
  4. run foreman-rake foreman_docker:cleanup (cleans up all data that this plugin introduced)
  5. yum remove tfm-rubygem-foreman_docker or apt remove ruby-foreman-docker
  6. yum remove tfm-rubygem-hammer_cli_foreman_docker or apt remove ruby-hammer-cli-foreman-docker unless you still use katello commands from it
  7. update apipie cache foreman-rake apipie:cache
  8. service httpd restart

foreman_docker enables provisioning and managing of Docker containers and images in Foreman, all of that under the GPL v3+ license.


  • Special view with logs and processes of Foreman managed containers
  • Wizard for container creation and cgroups configuration Select a docker image Cgroups configuration
  • Commit and upload containers: creates an image with the status of your current container Commit and upload to the docker hub
  • Container listing and basic CRUD operations



Please see the Foreman manual for appropriate instructions:

Red Hat, CentOS, Fedora, Scientific Linux (rpm)

Set up the repo as explained in the link above, then run

# yum install ruby193-rubygem-foreman_docker

Debian, Ubuntu (deb)

Set up the repo as explained in the link above, then run

# apt-get install ruby-foreman-docker

Bundle (gem)

Add the following to bundler.d/Gemfile.local.rb in your Foreman installation directory (/usr/share/foreman by default)

$ gem 'foreman_docker'

Then run bundle install and foreman-rake db:migrate from the same directory

To verify that the installation was successful, go to Foreman, top bar Administer > About and check 'foreman_docker' shows up in the System Status menu under the Plugins tab. You should also see a 'Containers' button show up in the top bar, similar to this


Go to Infrastructure > Compute Resources and click on "New Compute Resource".

Choose the Docker provider, and fill in all the fields. User name, password, and email are used so that Docker clients such as Foreman can make the host download images from the Docker hub. Your password will be encrypted in the database.

That's it. You're now ready to create and manage containers in your new Docker compute resource.

How to contribute?

Generally, follow the Foreman guidelines. For code-related contributions, fork this project and send a pull request with all changes. Some things to keep in mind:

  • Code from the master branch can contain features only present in Fog's master branch, we commit to wait for the next Fog release to put that code in a foreman-docker release.
  • Follow the rules about commit message style and create a Redmine issue. Doing this right will help reviewers to get your contribution merged faster.
  • Rubocop will analyze your code, you can run it locally with rake rubocop.
  • All of our pull requests run the full test suite in our Jenkins CI system. Please include tests in your pull requests for any additions or changes in functionality


Run rake test:docker from your Foreman directory to run the test suite.
