# 🌉 Unraveling the Mysteries of Docker Bridge Networks
[](https://github.com/TheToriqul/docker-bridge-networks)
[](https://github.com/TheToriqul/docker-bridge-networks/stargazers)
## 📋 Project Overview
As a passionate learner and technology enthusiast, I embarked on a journey to unravel the mysteries of Docker bridge networks. This project represents my hands-on exploration of creating custom bridge networks, attaching containers to multiple networks, and leveraging powerful tools like `ip` and `nmap` to examine network configurations and discover other containers.
Through this project, I aimed to gain a deep understanding of Docker networking concepts and develop the skills necessary to design and manage complex network architectures in containerized environments. By sharing my findings and experiences, I hope to inspire others to dive into the fascinating world of Docker networking and empower them to build robust and secure containerized applications.
## 🎯 Key Objectives
- Gain hands-on experience with creating and configuring custom bridge networks in Docker
- Understand the benefits and use cases of attaching containers to multiple networks
- Master the usage of `ip` command for examining network interfaces and IP addresses
- Explore the capabilities of `nmap` for network scanning and container discovery
- Develop a strong foundation in Docker networking concepts and best practices
## 🏗️ Project Architecture

## 💻 Technical Stack
-  Docker: Containerization platform
-  Alpine Linux: Lightweight container base image
-  Bash: Scripting for automation and command execution
## 🚀 Getting Started
🐳 Prerequisites
- Docker installed on your machine
- Basic understanding of Docker concepts and commands
⚙️ Installation
1. Clone the repository:
```
git clone https://github.com/TheToriqul/docker-bridge-networks.git
```
2. Navigate to the project directory:
```
cd docker-bridge-networks
```
🎮 Usage
1. Create custom bridge networks:
```
docker network create --driver bridge user-network
docker network create --driver bridge user-network2
```
2. Launch containers and attach them to networks:
```
docker run -dit --name container1 --network user-network alpine:latest
docker run -dit --name container2 --network user-network alpine:latest
docker run -dit --name container3 --network user-network2 alpine:latest
docker run -dit --name container4 --network user-network2 alpine:latest
```
3. Connect containers to additional networks:
```
docker network connect user-network2 container1
```
4. Examine network interfaces and IP addresses:
```
docker exec -it container1 ip addr
```
5. Install and use `nmap` for network scanning:
```
docker exec -it container1 apk add --no-cache nmap
docker exec -it container1 nmap -sn 172.18.0.0/16
```
For detailed commands and explanations, refer to the [reference-commands.md](reference-commands.md) file.
