Setup

Jenkins setup

• Install jenkins on a server
• Download the Blue Ocean and aws pipeline plugin
• Rolling deployment is implemented as per this manifest file

Kubernetes setup

Provision AWS kubernetes cluster (eks) using cloudformation scripts

# Create network infrastructure first
./create.sh udacity network
# After network stack has been created provision eks cluster
./create.sh udacity eks

Pipeline setup

The pipeline is setup using Blue Ocean and connected to the Github repository

• A Jenkinsfile describes the tasks in the pipeline
• A Linting stage checks for errors in the Dockerfile and html files
• A build stage builds the docker image and pushes to docker hub
• A deployment stage rolls out the deployment to aws kubernetes cluster

Result

• The linting stage was tested to be functional: Failing lint | Successful lint
• Deployment to kubernetes was successful: Successful Jenkins Deployment
• Update rollout was captured using kubectl describe deployments on the terminal with screenshot provided: Successful update rollout
