About

Katello is a systems life cycle management plugin to Foreman. Katello allows you to manage thousands of machines with one click. Katello can pull content from remote repositories into isolated environments, and make subscriptions management a breeze.

Currently, it is able to handle Fedora and Red Hat Enterprise Linux based systems.

Development

The most common way to set up Katello for development is to use katello-deploy. This will set up a Vagrant instance with the Katello codebase checked out. You can also run setup.rb directly with katello-deploy if you prefer to not use Vagrant.

There is also katello-devel-installer if you would like to use that.

If you have questions or issues with any of the above methods, feel free to ask for assistance on #theforeman-dev IRC channel or via the foreman-dev mailing list.

Test Run

At this point, the development environment should be completely setup and the Katello engine functionality available. To verify this, go to your Foreman checkout:

1. Start the development server

   cd $GITDIR/foreman
   
   rails s

2. Access Foreman in your browser (e.g. https://<hostname>/). Note that while Rails will listen on port 3000, the dev installer will set up a reverse proxy so HTTPS on port 443 will work.

3. Login to Foreman (default: admin and changeme)

4. If you go to https://<hostname>/about and view the "Plugins" tab, you should see a "Katello" plugin listed.

Reset Development Environment

In order to reset the development environment, all backend data and the database needs to be reset. To reiterate, the following will destroy all data in Pulp, Candlepin and your Foreman/Katello database. From the Foreman checkout run:

rake katello:reset

Found a bug?

That's rather unfortunate. But don't worry! We can help. Just file a bug in our project tracker.
