Docker Certified Associate Certification Training Course - Demo – Docker Networks

The video tutorial covers the use of Docker network drivers, including bridge, host, and none. It explains how to inspect these drivers using Docker commands and view their configurations in JSON format. The tutorial also demonstrates creating a custom Docker network with a specific driver. Key commands and outputs are highlighted to help users understand Docker networking.

What is the primary purpose of the bridge driver in Docker networking?

• To provide a default network for Docker containers

• To enable communication between Docker containers on the same host

• To connect Docker containers to external networks

• To isolate Docker containers from each other

When inspecting a Docker network driver, what format is the output typically in?

• XML

• YAML

• JSON

• CSV

What is a key difference between the host and none drivers in Docker?

• Host driver allows external access, none driver does not

• None driver is the default, host driver is not

• None driver supports IPv6, host driver does not

• Host driver isolates containers, none driver connects them

Which command is used to create a custom network in Docker?

• docker network build

• docker network setup

• docker network create

• docker network init

What driver is used when creating a MySQL network in the example provided?

• Overlay

• None

• Bridge

• Host
