| + | Quand un nœud est actif, il est capable de recevoir de nouvelles tâches à partir du manager : | ||
| + | |||
| + | * pendant un scale-up, | ||
| + | * pendant une une mise à jour progressive, | ||
| + | * quand un autre nœud reçois une instruction de se mettre en indisponibilité, | ||
| + | * quand un service se mets en échec sur un autre nœud | ||
| + | |||
| + | Rappelez-vous que la swarm contient 6 VM Docker : | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | ID HOSTNAME | ||
| + | y0war0lijmwhnexrfhfflulsd * | ||

| + | mo0dd5ech6ifdgd8pa6cjz896 | ||
| + | 5am2vd39pybytu1nd3oooabtq | ||
| + | </ | ||
| + | |||
| + | et que sur les 6 VM Docker, il y a 8 conteneurs, | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | ID NAME IMAGE | ||
| + | son0vgc73drb | ||

| + | yj0kexdcuo5u | ||
| + | 93jtbxqj2dyz | ||
| + | </ | ||
| + | |||
| + | dont deux se trouvent sur worker1 : | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | ID NAME IMAGE | ||
| + | pui4dnkepu27 | ||
| + | 93jtbxqj2dyz | ||
| + | </ | ||
| + | |||
| + | Mettez worker1 en mode d' | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | worker1 | ||
| + | </ | ||
| + | |||
| + | Constatez que le service web a été déplacé sur deux autres noeuds, **manager1** et **worker4** : | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | ID NAME IMAGE | ||
| + | son0vgc73drb | ||
| + | ojqyweuo65jw | ||

| + | </ | ||
| + | |||
| + | ====3.10 - Supprimer un Service=== | ||
| + | |||
| + | Pour supprimer un service il convient d' | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | web | ||
| + | |||
| + | docker@manager1: | ||
| + | ID NAME MODE REPLICAS | ||
| + | |||
| + | docker@manager1: | ||
| + | [] | ||
| + | Status: Error: no such service: web, Code: 1 | ||
| + | </ | ||
| + | |||
| + | ====3.11 - Sauvegarder Docker Swarm==== | ||
| + | |||
| + | La configuration de Docker Swarm est contenue dans le répertoire **/ | ||
| + | |||
| + | < | ||
| + | docker@manager1: | ||
| + | | ||
| + | root@manager1: | ||
| + | total 20 | ||
| + | drwxr-xr-x | ||
| + | -rw------- | ||
| + | drwx------ | ||
| + | -rw------- | ||
| + | drwxr-xr-x | ||
| + | </ | ||
| + | |||
| + | Le processus de sauvegarde necéssite qu'il y ait au moins **deux** Managers dans le Swarm. Le procédure de sauvegarde est : | ||
| + | |||
| + | * arrêt du service Docker sur le Manager à sauvegarder, | ||
| + | * sauvegarde du répertoire **/ | ||
| + | * redémarrage du service Docker sur le Manager concerné. | ||
| + | |||
| + | ====3.12 - Restaurer Docker Swarm==== | ||
| + | |||
| + | Le procédure de resturation est : | ||
| + | |||
| + | * arrêt du service Docker sur un nouveau Manager, | ||
| + | * suppression du contenu du répertoire **/ | ||
| + | * restauration du répertoire **/ | ||
| + | * exécution de la commande **docker swarm init --force-new-cluster** sur le nouveau Manager, | ||
| + | * ajout des Managers et Workers à Swarm. | ||
