🐳 Docker Level 3 - Day 1: Create a Custom Docker Network | Docker Series

Welcome to Day 1 of the Docker Level 3 Series! In this lab, you'll learn how to create custom Docker networks using the bridge driver and configure network addressing for container communication.

📌 Lab Objective:
Create a custom Docker bridge network with a specific subnet and IP range to provide isolated networking for future containerized applications.

🛠️ Task Requirements:

Docker Host:
🔹 App Server 2 (stapp02)

Network Details:
🔹 Network Name: news
🔹 Driver: bridge

Network Configuration:
🔹 Subnet: 10.10.1.0/24
🔹 IP Range: 10.10.1.0/24

💻 What You’ll Configure & Verify:

🔹 Create custom Docker networks
🔹 Configure bridge network drivers
🔹 Define custom subnet ranges
🔹 Configure IP allocation ranges
🔹 Inspect Docker network settings
🔹 Verify network creation
🔹 Understand container network isolation

📚 What You’ll Learn:

Docker Networking
Bridge Networks
Custom Network Creation
Subnet Configuration
IP Address Management
Container Communication
Docker Network Inspection
Infrastructure Networking Basics

🌟 Why This Lab Matters:
Custom Docker networks provide better control over container communication, security, and IP management. They are widely used in production environments to isolate applications and create predictable networking configurations.

🎯 Series: Docker Level 3 Series
