Installer Docker (16.04 lts)

Vers Docker, un outil de configuration, Installer Docker (16.04 lts), Docker : premiers pas (commandes de base)

Docker Community Edition (CE) pour les dev et petites équipe (sinon voir Docker Enterprise Edition = Docker EE)

https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-using-th...

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) stable"
sudo apt-get install docker-ce

ca marche ?

 sudo docker run hello-world

si oui, créer groupe et user (perso, le groupe était déja créé) : https://docs.docker.com/install/linux/linux-postinstall/

sudo groupadd docker
sudo monusermod -aG docker $USER

Fermer sa session (ou faire un sudo - USER et vérifier avec id -nG) et tenter

docker run hello-world

(on devrait avoir message d'erreur "home/user/.docker/config.json: permission denied", si 1ere install, effacer ~/.docker/)

 

systemd

docker toujours là avec   sudo systemctl enable docker

sinon faire              sudo systemctl disable docker

Gestion des logs

qui peuvent devenir volumineux voir https://docs.docker.com/config/containers/logging/configure/#configure-t...

 


Sur mon pc (archives) :

  • installé en ~/bin (/home/monusermod/bin/AppImages-master)
    coté espace disque, c'est AppImages-master/AppImageKit/.git/objects/pack qui est le plus gros 14 M. Cf  /etc/docker/key.json
    • fichiers de conf client à "/home/user/.docker"
  • et coté réseau, je vois docker0  (en 172.17.0.1) avec une mac adresse (asns oublier les vmnet1 et vmnet8).

install docker-compose

etre dans le dossier où tous ses projets docker sont :

sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
