инициируем кластер:
[root@swarm_master1_180~]# docker swarm init
Для добавления второй управляющей ноды, выполним команду на действующей управляющей ноде

теперь добавляем воркеры:
на мастере выполняем команду:
[root@swarm_master1_180~]# docker swarm join-token worker
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-3ce1cv9a3lh4eulgw93epia3ksv4jds8bx6sx5y4ifeooaxvid-b4hyll4eh37i9vd15zzwft0tn 192.168.1.180:2377

[root@swarm_master1_180 ~]# docker node demote 0ihuax8tievdrp3m8xjz5v1ys
Manager 0ihuax8tievdrp3m8xjz5v1ys demoted in the swarm.
после покидаем сам кластер:
[root@swarm_master1_180 ~]# docker swarm leave
Node left the swarm.
далее можем удалять ноды:
[root@swarm_master3_182 ~]# docker node rm 2u47nhxy05amaut0ljehr5hwe
