Coding withPuppet
Modules:• Units of Puppet DSL code that perform specific Infrastructure
actions :
• Manipulate files, users, packages and services
• Basic setup: templates, manifests, files
• http://forge.puppet.com
• Custom
• Combination of both
Module sources:
SampleModule
Install Apache:
class { 'apache': }
Add page:
file { ‘/var/www/html/index.html':
ensure => file, content => template('profiles/index.html.erb'),
}
SampleModule
Install Apache:
class { 'apache': }
What happens:
• Puppet determines how to install
• If it is installed…do nothing!
• Will install again if removed
