Docker Network Guardians

Introduction

Welcome to the world of Docker where a superhero team, consisting of elite containers, is on a mission to maintain peace and harmony in the digital universe. However, a notorious villain, known as the "Network Destroyer," has emerged with plans to disrupt the communication and connectivity of our heroic containers. The goal of this lab is to equip you with the skills to effectively manage Docker networks, thwarting the evil plans of the Network Destroyer.

Creating and Inspecting Networks

In this step, you will create and inspect Docker networks to ensure seamless communication between containers.

Introduction

To begin, let's create a custom bridge network named hero_network using the following command:

docker network create hero_network

This creates a dedicated network for our superhero team to communicate securely.

Connecting Containers to Networks

In this step, you will connect containers to the created network to establish their communication channels.

Introduction

Now, let's create a new container named super_container and connect it to the hero_network using the following command:

docker run -d --name super_container --network hero_network nginx

This will launch a container running the NGINX web server and connect it to our custom network.

Summary

In this lab, we delved into the crucial aspect of managing Docker networks. By creating custom networks and connecting containers to them, we have fortified our understanding of maintaining secure and efficient communication channels within the Docker ecosystem. Embrace these skills, for in the battle against the Network Destroyer, the prowess of network management holds significant importance.

Please note that this lab can include more steps, following the same format as above. Each step is designed to comprehensively cover fundamental network management skills in Docker.
