Docker - A Complete Hands-On Guide - Make Connection Between Containers Running on Different Networks

The video tutorial demonstrates how to establish communication between two containers on different networks using Docker. It covers creating containers C1 and C2, connecting them to the default bridge network and a custom test network, and troubleshooting communication issues. The tutorial also explains how to inspect containers to find their IP addresses and how to connect a container to multiple networks to enable communication.

What is the primary goal of creating containers C1 and C2 in different networks?

• To enable communication between different networks

• To test network speed

• To test container performance

• To create isolated environments

Which network is container C1 initially connected to?

• Test network

• Bridge network

• Host network

• None

What command is used to inspect a container's IP address?

• docker list

• docker check

• docker inspect

• docker view

Why was the ping command initially unavailable in the container?

• The IP address was incorrect

• The necessary package was not installed

• The network was down

• The container was not running

What is the solution to enable communication between C1 and C2?

• Use a different port

• Change the IP address of C2

• Connect C1 to the test network

• Restart both containers

What does connecting C1 to the test network demonstrate?

• Containers cannot communicate across networks

• Network drivers are not important

• A container can have multiple IP addresses

• A container can only have one IP address

What command is used to connect a container to a network?

• docker attach

• docker link

• docker join

• docker network connect
