About this Hands-on Lab

In this Live Environment, you’ve been asked by your manager to create a new network that all new Docker containers will be using. The network will be called app-bridge. After creating it, you will need to verify that it works by spinning up a nginx container that will use the new network.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Docker Network

The user will execute:

docker network create app-bridge
docker network ls to list the network

Results should look like:

f71240dce13d        app-bridge               bridge              local
Create the Docker Container

The user should be executing something like:

docker run -dt --name my-app --network app-bridge nginx:latest

docker ps should produce something like:

d5ffa729de09        nginx:latest        "nginx -g 'daemon of…"   7 seconds ago       Up 4 seconds        80/tcp              my-app

Additional Resources

  • Create a new bridge network called app-bridge.
  • Create a docker container called my-app that runs in the background.
  • It should use the latest nginx image.
  • The container should be on the app-bridge network.
