使用docker swarm init 命令初始化node1为管理节点。请根据你的IP地址调整这条命令。
docker@node1:~$ docker swarm init --advertise-addr 192.168.99.100
Swarm initialized: current node (7fkc9gml325pekzmemtfflp6s) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-3p6af6uy6aqlghj1zb1lwx8dw20kxcivdnwdjy4qmvsttc4jmf-7bimj049k2w5qqlqnkp1s1nq3 \
192.168.99.100:2377
To add a manager to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-3p6af6uy6aqlghj1zb1lwx8dw20kxcivdnwdjy4qmvsttc4jmf-4ybuxkzczpsmysmj7p8rq64ln \
192.168.99.100:2377
docker@node1:~$
返回结果是两条命令，一条用于添加manager节点，一条用于添加worker节点。
