1 用法

docker swarm init [OPTIONS]

 

 在manager0节点操作

192.168.7.102

[root@manager01 testswarm]# docker swarm init --advertise-addr 192.168.7.102
Swarm initialized: current node (v1ld63hqjtm8bx9z10bbhig5x) is now a manager.

To add a worker to this swarm, run the following command:

docker swarm join --token SWMTKN-1-1znl7nt91ucwz5doyuh53k6bhwihw7ked01804r60zfz8egg5c-5ej7hfjrflos3i4d4d49lfo4h 192.168.7.102:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

将 192.168.7.102 作为管理节点

添加其他管理节点，用docker swarm join-token manager 命令获得

[root@manager01 testswarm]# docker swarm join-token manager
To add a manager to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-1znl7nt91ucwz5doyuh53k6bhwihw7ked01804r60zfz8egg5c-7kr2iheffncoz6fqcj49n4fql 192.168.7.102:2377

在其他管理节点上执行 这个节点则作为管理节点添加进来

[root@node01 ~]# docker swarm join --token SWMTKN-1-1znl7nt91ucwz5doyuh53k6bhwihw7ked01804r60zfz8egg5c-7kr2iheffncoz6fqcj49n4fql 192.168.7.102:2377
This node joined a swarm as a manager.

 

 离开集群，在要离家的集群上执行

docker swarm leave -f

 准备

其中一台机器是经理（称为manager01），其中两台是工人（node01和node02）

192.168.7.102  manager01
192.168.6.9  node01
192.168.6.17 node02

 

在manager01 执行

[root@manager01 testswarm]# docker swarm init 
Swarm initialized: current node (shd6lryp0b2frr9ypzbqofdib) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-3bfwjhrg0sjsbrx8dqxez3hdmt38hmj0x18ph0w7prafw9c6fb-5hl8g51f7uimqleq7x9li5ukw 192.168.7.102:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

 

在 node01 和node02 上分别执行

docker swarm join --token SWMTKN-1-3bfwjhrg0sjsbrx8dqxez3hdmt38hmj0x18ph0w7prafw9c6fb-5hl8g51f7uimqleq7x9li5ukw 192.168.7.102:2377

 

在 manager01 上查看

[root@manager01 testswarm]# docker node ls
ID                            HOSTNAME    STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
shd6lryp0b2frr9ypzbqofdib *   manager01   Ready     Active         Leader           20.10.11
