docker swarm init [OPTIONS]

在manager0節點操作

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.

將192.168.7.102 作為管理節點

新增其他管理節點，用docker swarm join-token manager 命令獲得

[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

在其他管理節點上執行 這個節點則作為管理節點新增進來

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

離開叢集，在要離家的叢集上執行

docker swarm leave -f

準備

其中一臺機器是經理（稱為manager01），其中兩臺是工人（node01和node02）

192.168.7.102  manager01
192.168.6.9  node01
192.168.6.17 node02

在manager01 執行

[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 上分別執行

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

在manager01 上檢視

[root@manager01 testswarm]# docker node ls
ID                            HOSTNAME    STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
