Remiser tous les containers inutilisés
Remiser tous les containers inutilisés
Souvent quand on veut supprimer une image Docker, on obtient le message suivant :
➜ kawa ~/Documents/Docker.io/jekyll docker rmi 1a844a4ef377
Error response from daemon: Conflict, cannot delete 1a844a4ef377 because the container 96f6b66c031b is using it, use -f to force
2014/11/22 13:24:18 Error: failed to remove one or more images
En clair on a un ou un « tas » de container Docker toujours liés à l’image. En faisant docker ps, on remarque qu’il n’y a pas de container en cours d’exécution. En lançant la commande docker ps -a, on obtient l’ensemble des containers terminés ou pas :
➜ kawa ~/Documents/Docker.io/jekyll docker ps -a

Les containers terminés ont le status Exited. Pour se débarrasser de ces encombrants, voici la ligne de commande de nettoyage :
➜ kawa ~/Documents/Docker.io/jekyll docker ps -a | awk '/Exited/ { print "docker rm " $1 }' | sh
96f6b66c031b
a85d5ada2c1f

98a8be0a11ad
7b7bf19f472c
3c8a9694c5ca
98be4012d120
Enfin, nous allons pouvoir faire ce que l’on souhaitait faire initialement : supprimer une image Docker.
