[TP] Creating my first container


We are going to deploy a Docker container.

What you will learn in this TP :

Prerequisites

You must have a machine with Docker installed.

Deployment

In this section, we will deploy our first Docker container.
  1. Find and download the image
    We are going to deploy an Apache web server version 2.4.62. We must therefore find a ready-to-use image to download on our Apache web server.
  2. Deploy the container
    You must deploy our first container with the following characteristics:
    • Image: apache version 2.4.62
    • Port mapping: 83
    • Container name: my-first-container
  3. Container status check
    You must verify the proper functioning of your container. To do this, you must provide the docker commands for the following actions:
    • List running containers
    • List running and stopped containers
    • List only the my-first-container container
    • List containers that have the Label AUTOR:ROUSSELTM
  4. Container verification
    You must find the command to test the proper functioning of the web server container.
    WARNING: a running container is not necessarily a working container. You must check its logs and outputs.

Optimization

In this section, we will optimize our first Docker container.
  1. Build a lighter second container
    As indicated during the courses you should use official images in priority and especially the most optimal ones. You must choose another image more optimized in terms of size.
  2. Compare the disk consumption of the two containers
    You must find a command that displays only the two containers with their disk usage knowing that the two images have names containing 'my-'
