Using Test Kitchen With Puppet

From the kitchen.ci homepage:

Your infrastructure deserves tests too.

So lets write some integration test for our puppet code. We will use a super simple puppet manifest just deploying ntp as a hello world example focusing on test-kitchen instead.

Prerequisites

You need git (you should use it ;-) , ruby (use > 2.0) and bundler installed

Cover Your Bases

So let us start by creating a directory and a github repo for our project:

1mkdir puppet-kitchen-example
2cd puppet-kitchen-example
3git init
4hub create # this is optional

Next up we want to leverage bundler so lets create a Gemfile

bundle init
Writing new Gemfile to puppet-kitchen-example/Gemfile

We want to use test-kitchen and the kitchen-puppet gem. Until the patch gets pulled in we use a fork here:

echo 'gem "test-kitchen"' >> Gemfile
echo 'gem "kitchen-puppet"' >> Gemfile

bundle install

No we are able to initialize test-kitchen

1kitchen init
2      create  .kitchen.yml
3      create  test/integration/default
4      create  .gitignore
5      append  .gitignore
6      append  .gitignore
7      append  Gemfile
8You must run `bundle install' to fetch any new gems.

So lets do as advised and install the new dependencies

bundle install

Now we have to update the kitchen.yml file with puppet specific options from the kitchen-puppet gem See kitchen-puppet and provisioner options for details

cat > .kitchen.yml <<YAML

With this configuration in place we should be able to create the instances:

This looks very promising. Lets verify the current state kitchen list

Add Puppet and librarian-puppet To The Mix

Since we are trying to test a puppet-apply run we have to add puppet to the mix. Unfortunately the librarian-puppet integration with kitchen-puppet got me some errors. Let us use it anyways to fetch the puppet modules and move it out of the way afterwards.

echo 'gem "puppet"' >> Gemfile
echo 'gem "librarian-puppet"' >> Gemfile
bundle install

Now we can use librarian-puppet to create our Puppetfile

± librarian-puppet init
      create  Puppetfile

We want to use the Puppetlabs ntp module. lets change the Puppetfile to fetch it.

# OSX/BSD
sed -i '' 's#modulefile#mod "puppetlabs/ntp"#' Puppetfile

# Linux
sed -i 's#modulefile#mod "puppetlabs/ntp"#' Puppetfile

cat Puppetfile
#!/usr/bin/env ruby
#^syntax detection

forge "http://forge.puppetlabs.com"

# use dependencies defined in Modulefile
mod "puppetlabs/ntp"

# mod 'puppetlabs/stdlib'

# mod 'ntp',
#   :git => 'git://github.com/puppetlabs/puppetlabs-ntp.git'

# mod 'apt',
#   :git => 'https://github.com/puppetlabs/puppetlabs-apt.git',
#   :ref => 'feature/master/dans_refactor'

run

librarian-puppet install

and it will fetch the needed modules

ls modules
ntp    stdlib

to actually install ntp we have to create a manifest. Our test suite will run site.pp so let us create a simple one.

mkdir manifests
cat > manifests/site.pp << SITE

class { '::ntp':
  servers => [ '0.pool.ntp.org', '1.pool.ntp.org' ],
}

SITE

First Step To Success: Convergence

The infrastructure code is in place. The infrastructure itself is ready (read created), so we can do our operations work and install ntp on the nodes.

I have truncated the output a little bit.

This is the first part. Converge on Ubuntu. An interesting point: the testing code we are about to add needs a ruby on the system. test-kitchen started as a community project around chef. So test-kitchen leverages the ruby which comes with chef. That's why chef gets installed alongside puppet.

And the same command shines a light on test-kitchens beauty. We run it on as many OS as we put in the yml. How cool is that :-)

But this feels manual. It actually is. So lets automate the tests!

Create Some Integration Tests: Here Comes Bats

First we need a place for the testing code. Test kitchen creates a default location, so lets use that.

1ls test/integration/default

This is empty and has to be filled with our testing code. Lets start simple and add our manual test. A very interesting testing framework for this kind of tests is Bats: Bash Automated Testing System

mkdir test/integration/default/bats

cat > test/integration/default/bats/verify_installed.bats <<TEST

@test 'ntp is up and running' {
  pgrep ntp
}

@test 'ntp.conf contains correct servers' {
  grep 0.pool.ntp.org /etc/ntp.conf
}

TEST

Verify What We Have Got

Test kitchen uses busser to automate the heavy lifting. It will sync the local test folder to the nodes, install the test dependencies, and invoke the test on the node.

Very cool. But we knew that already. And the coolest part of it: It will run on all the OS flavors specified. Hook this up to a CI/CB system and have some extra productive time back :-)

Add Some More Tests. Serverspec To The Rescue

 1mkdir test/integration/default/serverspec
 2
 3cat > test/integration/default/serverspec/ntp_spec.rb <<TEST
 4require 'serverspec'
 5
 6include Serverspec::Helper::Exec
 7include Serverspec::Helper::DetectOS
 8
 9RSpec.configure do |c|
10  c.before :all do
11    c.path = '/sbin:/usr/sbin'
12  end
13end
14
15describe package('ntp') do
16  it { should be_installed }
17end
18
19describe service('ntp') do
20  it { should be_running }
21end
22TEST

Running kitchen verify now will not do the right thing. It will copy the serverspec but not run it. Run a kitchen converge first and kitchen will pick up the serverspec tests.

Ouch. Nasty error. This is the librarian puppet integration not working for me on osx. So let us move it out of the way for now as we already have installed the modules.
