pulet

Enhanced Puppet Control Repo and Tools.

Upstream Projekt auf Github

What

• Combination of control_repo and masterless Puppet localsetup
• One single repository with
  • hieradata
  • Puppetfile for librarian-puppet
  • Gemfile for tool installation with bundler
  • pulet script with various subcommands for setup, package and apply config
• Can be used without Puppetmaster
• Can be used as control repo on a Puppet master
• Package useful Tools and Rake Tasks to manage and check your Puppet Environment
• One-Command setup with all-in-one puppet-agent package from puppet collection repo.
• Alternative: Install Puppet using bundler and Gemfile to a separate path from system gems

Why?

• Small flexible system to puppetize servers for example in a home setup environment.
• Test/Develop Puppet on ephemeral systems without having them to register on a Puppetmaster.
• All the configuration and scripts in one git repository.

Bootstrap

Workspace Setup

To write and test the configuration on your laptop.

• clone repository
• configure pulet locally to use bundle as source for puppet
• install puppet and modules

git clone <repourl>
cd pulet
echo "installmethod='bundle'" >> ./pulet.conf.local
./pulet install

Bootstrap a Server

• VM with Ubuntu 14.04+ or EL 7+ Server.
• Git to clone the repo

Run the following commands to setup your server.

yum install git -y
git clone <repourl>
cd pulet
./pulet setup

Customization

• hieradata in data/
• Puppet Modules in Puppetfile
• profile manifests in site/profiles
• hierarchy in hiera.yaml
• pulet configuration and extensions in pulet.conf

How it works

First run:

installmethod=collection

• Install puppet-agent package from puppet collection repo
• Install bundler as gem using the ruby & gem from puppet-agent in /opt/puppetlabs/
• Install necessary missing gems with bundler

installmethod=bundler

• Install sytem packages ruby, ruby-dev and make
• Install bundler as gem
• Install puppet and dependencies with bundle to a local path

populate environment and puppet apply

• librarian-puppet installs the modules using the Puppetfile
• puppet apply with hieradata and modules

Commands

• ./pulet help: show all commands
• ./pulet install: install development environment with tools, without apply
• ./pulet apply: apply the current configuation, can be used as long as there are no changes in external modules.
• ./pulet setup: install & apply
• ./pulet facts: dump facts using custom facts in modules
• ./pulet check: validate and lint puppet code

Package and deploy configuration as rpm

The complete configuration incl. hieradata and modules can be packaged and deployed as rpm.

The configuration can then be directly applied without installing dependencies or modules on a node.

• ./pulet package: package modules and configuration to rpm in ./build/.
• Install pulet rpm and puppet-agent on a system
• /opt/pulet/pulet apply: Apply the configuration
