Docker Networking

Pick the right network driver, publish ports safely, manage user-defined bridges and know when to use host, overlay, macvlan and none.

Practice interactively →

What you will learn

• Choose the bridge, host, overlay, macvlan or none driver for a situation
• Publish ports with -p and limit the listening interface
• Create user-defined bridges and attach or detach running containers
• Explain how host, overlay, macvlan and none networks behave

Lessons

1. Network drivers and when to use them

   Docker ships bridge, host, none, overlay and macvlan; pick a driver by who the container needs to talk to.

2. Bridge networks and port mapping

   Containers on a bridge have private IPs; publish ports with -p so the host and the outside world can reach them.

3. Managing user-defined bridges

   Create networks, attach containers at creation or while running, detach them and remove networks in the right order.

4. Host, overlay, macvlan and none

   Four special drivers — share the host network, span several hosts, plug straight into the LAN, or switch networking off.
