Secure Docker Deployment

Secure docker instance with basic Authentication

Nginx reverse proxy with Basic Authentication

Introduction:

Recently, I faced a challenge to deploy a docker web application with basic authentication. Instead of modifying the docker web application, I deployed the docker instance behind the Nginx reverse proxy with Basic Auth. So I want to share the process and challenges I faced in order to deploy the docker web app.

Stage 1: Setup Nginx and Basic Authentication:

sudo apt-get install apache2-utils
