CI/CD Pipeline Automation

This repository contains automation scripts and configurations to build, deploy, and harden a Node.js application in a Kubernetes environment.

Task

Build some type of automation that could eventually be run in a CI/CD pipeline that does the
following:

1. Write a shell script to build docker image with the following requirements
    a. Read the base image name and base image tag from a text file.
    b. Use github repo https://github.com/nrupendesai/debugApp for docker file. Modify
    the dockerfile as needed.
    c. Build docker image from base image using #a.

2. Deploy node application image you built in step #1 with the following requirements
    a. Build/create helm chart
    b. Expose the API using NGINX Ingress Controller
    c. Attach ephemeral storage to the container

3. Harden the container using common CIS rules
    a. Container should run as non-root user
    b. The pod filesystem should be read-only

While working on the Application you can assume that,
1. You have cluster admin access to deploy the application.
2. The nginx ingress controller is deployed. The available ingress class i `rf-nginx`
3. The cluster is also configured with storage provisioner. The available storage class is
`rf-storage-rw`

Send us this automation with some details on how you created it
