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.
