Docker

These days almost every software developer has come to know about Docker. In fact, most people use it in their software development journey. Almost everyone knows about Docker—how to write a Dockerfile, how to write a Docker Compose file, how to push or pull images, how to reduce image size, how to configure Docker networks, persistent volumes, Docker commands, etc.

Docker networking enables containers to communicate with each other, the host machine, and external networks while maintaining isolation. Each container runs in its own network namespace, which includes separate IP addresses, routing tables, and interfaces, preventing conflicts with the host or other containers.

To operate Docker workloads reliably, you need resource visibility and data persistence. This setup adds:

Shipping applications in Docker is easy — but shipping lightweight, secure, and optimized images is where the real DevOps skills shine. That’s exactly what Multi-Stage Dockerfiles help you achieve.

Modern infrastructure generates thousands of data points every second—metrics, logs, traces, events, service health, and user activity. For DevOps teams, monitoring all of this in real time is crucial.

Docker is a powerful tool that allows you to encapsulate your application and its dependencies into a standardized unit for software development. One common scenario when using Docker is the need to invoke APIs running on one Docker container from another Docker container. This article will guide you through the process step by step.

Before diving into setting up a reverse proxy with Nginx, it's essential to first understand what a reverse proxy is. To effectively use Nginx as a reverse proxy, we need to clear any confusion around the concept of reverse proxies.
