## Puppet
|
|
|
|
### What is Puppet
|
|
|
|
Puppet is a configuration management tool where a developer describes the target state of a number of resources using a declarative language.
|
|
In simple words, Puppet is a system for automating system administration tasks.
|
|
|
|
Here are a few resources that will help in introduction to Puppet:

### Where to start
|
|
|
|
- Play around with Puppet. You might want to use <a href="https://learn.puppet.com/">Puppet Training</a>
|
|
- Adopt <a href="https://docs.puppet.com/hiera/">Hiera</a> as early as possible to allow you to write clean code
|
|
- Adopt the Roles and Profiles pattern as early as possible
|
|
- Once Hiera and the Roles and Profiles pattern have been adopted look into the following:
|
|
- Test Driven Development using <a href="https://github.com/rodjek/rspec-puppet/">rspec-puppet</a>
|
|
- Deployment through controlled environments with <a href="https://puppet.com/docs/pe/2019.0/r10k.html">r10k</a>
|
|
|
|
### Hiera
|
|
|
|
Use Hiera to separate your data / parameter values from your Puppet code
|
|
|
|
### eyaml
|
|
|
|
When you need to store sensitive data such as password for service accounts, use eyaml as a Hiera back-end. The secrets will become available in your puppet code as facts.
|
|
|
|
Have a look at the following article for more information: <a href="https://puppet.com/blog/encrypt-your-data-using-hiera-eyaml">Encrypt Your Data Using Hiera-Eyaml</a>
