How to Password Protect a Node Application in OpenShift Using Nginx Sidecar?

Securing your applications is crucial, and one effective way to do that is by password-protecting them. In this guide, we'll explore how to protect a Node application in OpenShift by utilizing an Nginx sidecar container.

Why Use Nginx Sidecar?

A sidecar container is a common pattern in Kubernetes and OpenShift environments where additional functionalities, like logging, monitoring, or in this case, security, are included alongside the main application container. Nginx can act as a reverse proxy and additional security layer by handling HTTP authentication before requests reach your application.

Prerequisites

OpenShift cluster: Make sure you have access to an OpenShift cluster.

Nginx knowledge: Basic understanding of Nginx configuration.

Step-by-Step Implementation

Step 1: Create the Password File

First, generate a password file for basic HTTP authentication:

Once deployed, access your Node application via the Nginx proxy. You should be prompted to enter the username and password you created earlier.

Conclusion

By using an Nginx sidecar container to password-protect your Node application in OpenShift, you ensure an extra layer of security while leveraging the robust features of both Nginx and OpenShift. This approach helps protect sensitive information and restricts access effectively to your application.
