A Full Stack Dockerize NodeJS

Write a basic Node.js/Express application that responds to several routes and communicates with MongoDB or SQLite to save and retrieve some information (e.g. a person, a pet, a car, you choose)

Having written the application, write several unit tests (using Mocha/Chai or Jest) to ensure the application behaves as expected.

Dockerise your application, and demonstrate running it in a container locally (on your computer)

Extra 1: Ensure good code style with ESLint Extra 2: Create a basic Kubernetes Helm chart for the app and deploy (locally in Minikube or on the cloud) Extra 3: Set up TravisCI to run a unit test check every time you update your repository and build the Docker container

Your code deployment should be tracked on a public git repository (on GitHub), and should include sufficient documentation/instructions to replicate. Follow good git practice to separate the development of each unit test.

OS Requirement

• Install NodeJS
• Install Docker
• Install Kubernetes
• Install Minikube
• MongoDB

Run Locally without Docker / Kubernetes

• Edit mongodb config.js file in the root of your project to your mongodb URL
• Run npm install
• Run npm start
• Go to http://localhost:5000

Run with Docker / Kubernetes / Minikube

# Start Docker / Minikube / Kubernetes
# Modify node-controller.yaml file with docker image name e.g "<DOCKER_USERNAME>/node-image:full-stack"

# Run npm install
npm install

# Build docker image
docker image build -t node-image .

# Docker login with credentials
docker login

# To get image ID use command - `docker image ls`
# Create a tag for docker image
docker tag <IMAGE_ID> <DOCKER_USERNAME>/node-image:full-stack

# Docker push
docker push <DOCKER_USERNAME>/node-image

# Create service and pod for NodeJS and MongoDB
kubectl create -f node-service.yaml

kubectl create -f node-controller.yaml

kubectl create -f mongo-service.yaml

kubectl create -f mongo-controller.yaml

# Run services to initiate connection

- kubectl describe svc mongo

- Kubectl describe svc full-stack

# Get IP ADD | NODEPORT use  command below
- kubectl describe svc full-Stack

- minikube ip
