Repo for project "CI/CD with Jenkins and Beaker" in IMT3005 - Infrastructure as Code

Introduction

The goal of the project is to experiment with CI/CD using OpenStack, Jenkins and Beaker. I'm trying to accomplish an infrastructure with a Puppet Master, a Jenkins server and an application server that runs CI/CD on any changes made, and ultimately deploys them into production.

Please see the report for more details about the project itself. It was created from the LaTeX found in report/.

Structure

This repository is mainly a control repository based on this template, but it also contains an infrastructure definition in OpenStack Heat that brings up a stack running the control-repo. The original README from the template is stored here.

Here's a visual representation of the structure of this repository:

Usage

The Vagrant environment described in the above section includes everything you need in terms of tools. You do however need access to an Openstack cloud environment to deploy the stack in.

To create the stack

  1. (Either fork this repository and make r10k clone your forked repository, or alter the boot script of manager to pull using HTTPS, not SSH. This is because you need my private Github key to clone the repository with ssh. This is an unfortunate barrier of entry, but I have not had time to fix it.)
  2. Provide your own environment file based on infrastructure/topology_env_example.yaml. (e.g. cp infrastructure/topology_env_example.yaml infrastructure/topology_env.yaml, and fill it with your environment specific settings).
  3. Create the stack defined in infrastructure/topology.yaml, and provide the environment file you made earlier. (e.g. openstack create -t infrastructure/topology.yaml -e infrastructure/topology_env.yaml cicd_stack)
  4. Profit! The stack should configure itself. Find the floating IP address of the Jenkins server and browse to it on port 8080. When the stack is fully provisioned you will see a Jenkins server running here with a few jobs. The admin username/password is insecureAdmin/insecurePassword.

TODO

(WONTFIX, as project is finished)

  • Configure Blue Ocean plugin for Jenkins.
  • Include security groups in infrastructure definition.
  • Separate out general installation in own boot script (to be used with CI).
  • Implement missing functionality described in report.
