🐳 Docker Networking & Volumes — Explained Simply

Docker doesn’t just run containers.

It also handles how containers talk and where data lives.

Two key concepts:

👉 Networking

👉 Volumes

🌐 Docker Networking (How containers communicate)

By default, containers are isolated.

Docker networks allow containers to talk to each other and the outside world.

🔹 Common Docker Network Types

1️⃣ Bridge (default)

• Containers on same host
• Can communicate via container name
• Most commonly used

docker networkls

2️⃣ Host

• Container shares host’s network
• Faster, but less isolation
