Stone DevOps Challenge

Presentation

This project contains the necessary files for a CI/CD example environment.

Tools used on this project:

Jenkins
Ansible
Docker

They are installed on CentOS 7 on Google Cloud. The web server with the example app is running on docker container on port 3000.

How does the magic happens ?

The Jenkins is responsible to clone this repo, create a docker image, install the source code into this image and run the tests. All these steps are available on Jenkinsfile. Once everything works well, jenkins will call the ansible-playbook using the webserver-playbook.yml file as playbook. This playbook will stop the current image and start a new version of image created by Jenkins. To be sure which version of image the ansible should start, every image created by jenkins has label with the build ID.

The docker image is created using the Dockerfile.

Installation steps on Jenkins

That's it! Now you are able to clone, test and deploy this app using one click :)
