1、查看节点

bash 复制代码

root@docker-swarm-manager:~# docker node ls
ID                            HOSTNAME               STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
lzjdu37bi9uwuba2vaeoydyt5 *   docker-swarm-manager   Ready     Active         Leader           20.10.17
z80g2c41838egi2fd52dix4ga     docker-swarm-node      Ready     Active                          20.10.17

2、Node节点添加标签

bash 复制代码

docker node update --label-add my-label=tan z80g2c41838egi2fd52dix4ga

3、部署到指定work节点

bash 复制代码

docker service create --network tankesong_net --name my-nginx -p 8090:80 --replicas 2 --constraint 'node.labels.my-label==tan' nginx

4、查看部署节点

bash 复制代码

root@docker-swarm-manager:~# docker service ps my-nginx
ID             NAME             IMAGE          NODE                DESIRED STATE   CURRENT STATE            ERROR                              PORTS
