Cas d'utilisation du pilote r\u00e9seau None\n\nLe pilote r\u00e9seau None est le plus simple de tous les pilotes r\u00e9seau Docker. Il d\u00e9sactive compl\u00e8tement le r\u00e9seau pour le conteneur. Au sein du conteneur, seul l'interface loopback est cr\u00e9\u00e9e. Aucun interface r\u00e9seau n'est cr\u00e9\u00e9e. Aucune adresse IP n'est attribu\u00e9e. Les conteneurs utilisant ce pilote r\u00e9seau ne peuvent pas communiquer entre eux ou avec le pont Docker.\n\nLe pilote r\u00e9seau None est utile dans les cas suivants :\n\n- Lorsque vous souhaitez d\u00e9sactiver compl\u00e8tement le r\u00e9seau pour un conteneur.\n- Lorsque vous voulez un conteneur isol\u00e9 sans aucune connectivit\u00e9 r\u00e9seau.\n- Lorsque vous voulez un conteneur qui ne peut pas communiquer avec d'autres conteneurs ou avec le pont Docker.\n\nPour utiliser le pilote r\u00e9seau None, vous pouvez utiliser la commande suivante :\n\n```bash\ndocker run --network none votre_image\n```\n\nCela cr\u00e9era un conteneur utilisant le pilote r\u00e9seau None. Le conteneur n'aura aucune connectivit\u00e9 r\u00e9seau et ne pourra pas communiquer avec d'autres conteneurs ou avec le pont Docker.<\/h2>\n

Comment utiliser le pilote r\u00e9seau None\n\nLe pilote r\u00e9seau None est un pilote r\u00e9seau sp\u00e9cial qui d\u00e9sactive le r\u00e9seau. Lorsqu'il est d\u00e9fini sur none, Docker ne configure pas d'interface r\u00e9seau dans le conteneur et ne configure pas non plus le mappage de ports. Si vous souhaitez compl\u00e8tement d\u00e9sactiver le r\u00e9seau, c'est le bon choix.\n\nPar exemple, vous pouvez ex\u00e9cuter une base de donn\u00e9es simple comme MariaDB avec le pilote r\u00e9seau None :\n\n$ docker run -d --net none --name db redis\n\nDans cet exemple, le conteneur nomm\u00e9 db s'ex\u00e9cute avec le pilote r\u00e9seau None et ne peut pas communiquer avec d'autres conteneurs.\n\nLe pilote r\u00e9seau None est utile pour les conteneurs qui n'ont pas besoin de r\u00e9seau ou pour lesquels vous souhaitez d\u00e9sactiver compl\u00e8tement le r\u00e9seau pour des raisons de s\u00e9curit\u00e9.<\/h2>\n
