Introduction

  • Docker engine : Docker engine est un logiciel qui permet de créer, de déployer et de gérer des conteneurs. Les conteneurs sont des environnements isolés qui contiennent tout le nécessaire pour exécuter une application, y compris le code, les bibliothèques système, les outils système et les fichiers système.
  • Docker desktop : Docker desktop est une interface graphique optionnel pour Docker engine. Lors de l'installation de docker desktop docker engine est automatiquement installée.

Installation de Docker engine sur Ubuntu 24.XX

  • Pour commencer désinstaller les anciennes versions de Docker

    for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

  • Mettre à jour le gestionnaire de paquet

    sudo apt update

  • Installer curl et ca-certificates

    sudo apt install curl ca-certificates

  • Créer le répertoire /etc/apt/keyrings avec les permissions 0755

    sudo install -m 0755 -d /etc/apt/keyrings

  • Télécharger la clé GPG de Docker

    sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc

  • Changer les permissions de la clé GPG

    sudo chmod a+r /etc/apt/keyrings/docker.asc

  • Ajouter le dépôt Docker à Apt sources

    echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

  • Installer Docker engine

    sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

  • Créer un groupe docker

    sudo groupadd docker

  • Ajouter votre utilisateur au groupe docker

    sudo usermod -aG docker $USER

  • Mettre à jour les permissions du groupe docker

    newgrp docker

  • Tester l'installation de Docker engine

    docker run hello-world

    • Réponse attendue :

      Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
        (amd64)
3. The Docker daemon created a new container from that image which runs the
        executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
        to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
