Overview

Docker networking enables containers to communicate with each other and external systems. Understanding network types and configurations is crucial for containerized applications.

<aside> ℹ️ Why It Matters: Understanding Docker Networking is essential for building robust, scalable, and secure modern applications.

Key Concepts

• [x] Bridge Network - Default network driver
• [x] Host Network - Use host's network directly
• [x] Overlay Network - Multi-host networking
• [x] Macvlan Network - Assign MAC addresses
• [x] None Network - No networking
• [x] Custom Networks - User-defined networks
• [x] Network Aliases - Service discovery
• [x] Port Mapping - Expose container ports

Common Use Cases

<aside> 💡 Where to Apply Docker Networking

                        Container-to-container communication
                        Microservices networking
                        Load balancing
                        Service discovery
                        Isolating application tiers
                        Connecting to external services

Best Practices

• [x] Use custom bridge networks instead of default
• [x] Name containers for easy discovery
• [x] Use network aliases for service names
• [x] Implement network segmentation for security
