### 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

## Configuration

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.

| Foreman | Plugin |

| >= 1.5         | 0.0.1 - 0.0.3   |

| >= 1.6         | 0.1.0 - 0.2.0   |

## Known bugs

* Unsaved new containers leave a dangling container object in the database

* Power operations redirect to compute resource container view even for managed container

## How to contribute?
