Easy to use demo of Flapjack managed with Vagrant


  • Vagrant
  • VirtualBox or VMware Fusion
  • (optional) vagrant-cachier - vagrant plugin install vagrant-cachier
    • caches packages so any subsequent vagrant up will use cached packages, and therefore be much faster if you're not on a super fast internet link.


git clone
cd vagrant-flapjack

Flapjack Vagrant currently supports the following Linux distro releases:

  • precise - Ubuntu 12.04
  • trusty - Ubuntu 14.04 (default)
  • wheezy - Debian 7.7
  • centos-6 - CentOS 6

To choose the distro & release version, use one of the following to export the distro_release environment variable.

export distro_release='precise'
export distro_release='trusty'
export distro_release='wheezy'
export distro_release='centos-6'

Flapjack Vagrant can install either the latest main (default) or experimental package from a given major series. To choose your component and major release export the following variables. The default is the v1 main release.

export flapjack_component='experimental'
export flapjack_major_version='v1'

# Or if you want to use the 0.9 series:
export flapjack_major_version='0.9'

Then, start the vagrant instance:

vagrant up

If you get some errors during package installation that look like corrupt package files or similar, you may want to disable the caching by running vagrant up with the DISABLE_VAGRANT_CACHE environment variable set:


Optional Extras

  • Tutorial Mode *
export tutorial_mode="true"

This installs the Flapjack Diner Ruby gem. It could be useful for running through tutorials. FIXME: is it useful / required for any published tutorials?

  • With Sensu *
export with_sensu="true"

This will also install and configure Sensu along with its dependencies (RabbitMQ, OS's Redis).

If you already created your vm you can add Sensu by doing a provision, eg:

with_sensu="true" vagrant provision




Flapjack, Redis, Icinga and Nagios should all be running after vagrant up completes, you can access their web interfaces with the links above. To poke around further, ssh into the VM:

vagrant ssh

Icinga is configured to feed its events to Flapjack using flapjackfeeder. If you want to also enable Nagios to feed its events to Flapjack, you can enable the flapjackfeeder event broker module like so:

vagrant-flapjack$ vagrant ssh
vagrant@flapjack:~$ sudo sed -i 's!#broker_module=/usr/local/lib/flapjackfeeder!broker_module=/usr/local/lib/flapjackfeeder!' /etc/nagios3/nagios.cfg
vagrant@flapjack:~$ sudo service nagios3 restart


Flapjack packages now have testing, using both serverspec and capybara. The serverspec tests will bring up the vagrant image if it isn't already up.

To run all the tests, run:


To run the serverspec or capybara tests separately, run:

rake serverspec
rake capybara

NOTE: for some reason you cannot use bundle exec with these commands. Not sure why. You get lots of errors like this one:

  1) Package "flapjack"
     On host ``
     Failure/Error: Unable to find matching line from backtrace
     NoMethodError: undefined method `source_location' for nil:NilClass

       undefined method `source_location' for nil:NilClass
     # ./spec/serverspec_spec_helper.rb:20:in `block (2 levels) in <top (required)>'
