Deploying a Frontend Application with Dynamic Environment Variables Using Docker, Kubernetes, and Nginx

This guide demonstrates how to deploy a frontend application using Docker and Kubernetes (k8s) with dynamic environment variables that can change across different namespaces. We will use Nginx as a web server to serve the frontend static files.

1. Create a Dockerfile

Create a Dockerfile for your frontend project:

# Use a Node.js base image
FROM node:14 AS build
