Puppet Control Repo

This is project developed for our Infrastructure as Code project. It automates the deployment of a Golang REST API, which uses a PostgreSQL database. Changes to the Golang repository triggers automatic rebuilds and redeploys the API. It uses this example Golang REST API to demonstrate connectivity, aswell as read and write access to the database. This can be changed in Hiera.

The repository automatically used by IaC-Heat on deployment.

The project is based on this puppet control repo by Erik Hjelmås, which in turn is based on this puppet control repo template by puppetlabs.

Brief structure

Each of the nodes are assigned a role (see manifests/site.pp). Each role consists of several profiles which provide various functionality.

A Telegraf, InfluxDB, Grafana stack is used for monitoring.

Testing

For unit testing we use rspec-puppet. For acceptance testing we use Serverspec.

Unit testing

To run the unit tests, simply cd into site-modules/profile/ and run rake.

cd site-module/profile
rake spec

Acceptance testing

To run the acceptance tests you will have to add some lines to your ssh configuration file.

vi ~/.ssh/config

And add the following (note that the Host-field should match the hosts variable in the Rakefile):

Host balancer01.iac
     HostName <ip to machine>
     User ubuntu
     Port 22
     IdentityFile <path to private key>
Host database01.iac
     HostName <ip to machine>
     User ubuntu
     Port 22
     IdentityFile <path to private key>
Host frontend00.iac
     HostName <ip to machine>
     User ubuntu
     Port 22     
     IdentityFile <path to private key>

When the ssh-config is ready, simply cd into the root directory of the control repo and run rake.

rake spec
