Bit hyperbolic...

Now on the DEFRA CAPD project

So first up!

puppet-install-shellhttps://github.com/petems/puppet-

install-shell

· Shell (not bash!) script· Installs Puppet on (most!) Unix flavour

machines· Plan to support all platforms officially

supported by Puppet (https://docs.puppetlabs.com/guides/platforms.html)

· Currently supports EL, Fedora, Debian, Ubuntu, OSX and Arch!

A mix of various provisioner scripts I found around the

Internet

A lot oftest -f

machine=`uname -m`os=`uname -s`

if test -f "/etc/lsb-release" && grep -q DISTRIB_ID /etc/lsb-release; then platform=`grep DISTRIB_ID /etc/lsb-release | cut -d "=" -f 2 | tr '[A-Z]' '[a-z]'` platform_version=`grep DISTRIB_RELEASE /etc/lsb-release | cut -d "=" -f 2`

Quick one step to get puppet installed on a machine:

curl https://raw.github.com/petems/puppet-install-shell/master/install_puppet.sh | sudo sh

Live Demo Warning!

Its main use was for another tool:

vagrant-puppet-install

Well, making is a strong term...

Took over maintenance of!

Easy way to provision servers created with Vagrant

Works with Vagrant Cloud Providers too!

Vagrant.configure("2") do |config|

config.vm.define :ubuntu do |ubuntu| ubuntu.puppet_install.puppet_version = '3.6.1'

ubuntu.vm.box = "puppetlabs/ubuntu-14.04-64-nocm"

ubuntu.vm.provision :puppet do |puppet| puppet.manifests_path = File.expand_path('../../../support/manifests', __FILE__) puppet.manifest_file = "base.pp" end

ubuntu.vm.provision "shell", inline: "puppet --version"

end

Nice and simple...· Checks the version you've defined is valid (from

RubyGems.org...)· Rsyncs or downloads a script that installs puppet (uses puppet-install-shell script by

default!)· Standard error handling and catching

· Windows support soon!

Live Demo Warning!

And finally

Puppet-doc-lint· Tool for module maintainers

· Looks through your Puppet documentation and shows when you have undocumented

parameters· Or documentation on parameters that are now

missing

Current status: Very brittle!· New syntax breaks it!· A few false positives

· A few false negatives...

But people are using it (woo!)

Well, a few...

@electrical (Richard Pijnenburg) is my current ginea pig!

He's been using it for logstash Puppet module

It's helped him, so it's helped at least 1 person! :)

Live Demo Warning!

That's it!
