Jenkins CI/CD pipeline

This basic Django application was containerized with Docker and deployed to Kubernetes via minikube. Also implements a Jenkins CI/CD pipeline to handle autodeployments.

Requirements

  • Ubuntu Host System
  • Minikube (latest)
  • Virtualbox
  • Helm
  • Dockerhub account
  • Github account

Project Setup Instructions

  • Install minikube and enable the following addons:
    • helm-tiller
    • ingress-dns
  • Install the official jenkins chart named stable/jenkins using helm install command.
  • Install Kubernetes, Docker jenkins plugins from within the Jenkins dashboard.
  • Check that you can connect to Kubernetes from jenkins system settings section.
  • Generate an access token in Dockerhub and add it as a jenkins security credential.
  • Use the fabric8-rbac.yaml to create a cluster role and bind the default user to that role, adjust to meet your permission targets.
  • Run minikube tunnel to allow the created service to get an external ip address when created.

Deployment

  • Use the guide provided in the jenkinsfile to test that the pipeline runs a docker image build and handles deployment correctly. Switch values and credentials.

  • The following files should also be adjusted to your workflow:

    • deployment.yaml & service.yaml. These files create a deployment and creates the service which exposes the deployment.

  • In dashboard, check the allocated external ip for the created service and click to see your app.
