puppet - instant data center

Instant Data

CenterA Data Center on your Laptop

Bryan Belanger bbelanger@azcender.com

Why Developing in Your Data

Center is a Bad Idea

• Virtual Machines / Nodes tend to be expensive

• You’ll break your nodes… lots

• You can break your Puppet Master

Do It All on your Local Box

• Easy way to test and run your Puppet architecture

• No overhead in maintaining dev nodes

• Tear down and rebuild nodes quickly and easily

• If you break the Puppet Master who cares

The Basic Blocks

http://git-scm.com

http://ruby-lang.orghttp://vagrantup.com

http://virtualbox.org

Other Requirements

• vagrant-oscar:

vagrant plugin install oscar

• vagrant-vbguest:

vagrant plugin install vagrant-vbguest

• librarian-puppet gem:

gem install librarian-puppet

• nokogiri gem:

gem install --install-dir ~/.vagrant.d/gems nokogiri -v '1.6.4.1'

• vagrant-centos7_fix:

vagrant plugin install vagrant-centos7_fix

• puppet gem:

gem install puppet

Other Considerations

• You’ll need an i5 or better processor

• You need a minimum of 8 GB

• 16 GB is recommended

Using the Oscar Plugin

• boxes.yaml

• Hash of boxes and their location

• pe_build.yaml

• Specifies location and version of

Puppet Enterprise

• roles.yaml

• Virtual machine configuration

details

• vms.yaml

• Ties boxes and configuration

together
