1、创建一个 Docker service

$ docker service create --replicas 1 --name myhelloworld alpine ping docker.com

 

--replicas: 标识运行实例个数

--name： service 的名称

alpine ping docker.com: 运行参数，表明service将运行一个Alpine Linux container，并且执行 ping docker.com 的命令。

 

 

2、审视 Docker service

$ docker service inspect --pretty myhelloworld

--pretty: 指定返回为简约格式，否则，讲义JSON格式返回

 

3、查看 service 上运行 node 的情况

$ docker service ps myhelloworld

 

 

4、查看容器详细信息

$ docker ps

 

 

5、修改service 规模

$ docker service scale myhelloworld=5

 

6、删除 service

$ docker service rm myhelloworld

 

7、轮询更新

$ docker service create \

--replicas 3 \ --name redis \ --update-delay 10s \ redis:3.0.6

 

 

 查看 service 状态

$ docker service inspect --pretty myredis

 

 

8、更新 service

更新节点

$ #docker service update --image redis:3.0.6 myredis

指定service的某个节点排满状态

$ docker node update --availability drain worker1

此后，将不会再在worker1 上面分派任务

9、查看swarm的存在的service列表

[root@node1 docker-compose]# docker service listID            NAME                MODE        REPLICAS  IMAGE6yv909v5mja6  eureka_peer3        replicated  1/1       192.168.6.132:5000/jacky/microservice-discovery-eureka-ha:1.0-SNAPSHOTm6wc4dcl0vts  eureka_peer1        replicated  1/1       192.168.6.132:5000/jacky/microservice-discovery-eureka-ha:1.0-SNAPSHOTun42g3kd94en  eureka_userService  replicated  1/1       192.168.6.132:5000/jacky/microservice-provider-user:1.0-SNAPSHOTy8gyq056nm3f  portainer           replicated  1/1       portainer/portainer:latestzg53vjcj4noa  eureka_peer2        replicated  1/1       192.168.6.132:5000/jacky/microservice-discovery-eureka-ha:1.0-SNAPSHOT

 10、删除swarm中的服务

[root@node1 docker-compose]# docker service rm eureka_userServiceeureka_userService[root@node1 docker-compose]# docker service lsID            NAME          MODE        REPLICAS  IMAGE6yv909v5mja6  eureka_peer3  replicated  1/1       192.168.6.132:5000/jacky/microservice-discovery-eureka-ha:1.0-SNAPSHOTm6wc4dcl0vts  eureka_peer1  replicated  1/1       192.168.6.132:5000/jacky/microservice-discovery-eureka-ha:1.0-SNAPSHOTy8gyq056nm3f  portainer     replicated  1/1       portainer/portainer:latestzg53vjcj4noa  eureka_peer2  replicated  1/1       192.168.6.132:5000/jacky/microservice-discovery-eureka-ha:1.0-SNAPSHOT

注意：正在运行中的swarm 服务也是可以删除的
