2、docker swarm joib --token *** 192.168.1.17
3、docker network ls
4、docker node ls
5、docker node promote server02
docker node promote server03
6、docker node ls
7、docker service create --name test1 apline ping www.baidu.com
8、docker service ls
9、docker service inspect test1
10、docker service ls
11、docker service logs test1
12、docker service create --name nginx --detach=false nginx
13、docker service ls
14、docker service update --publish-add 8080:80 --detach=false nginx
15、docker service scale nginx=3
16、docker service ls
17、docker service ps nginx
18、docker ps
19、docker exec -it 749 sh
ping nginx

二、自定义网络
1、docker network ls
2、docker network create -d overlay drunk-overlay
3、docker network ls
4、docker service ls
5、docker service rm nginx test1
6、docker service create --network drunk-overlay --name nginx -p 8080:80 --detach=false nginx
7、docker service create --network drunk-overlay --name test --detach=false mycentos:1.0 ping www.baidu.com
docker service create --network drunk-overlay --name test --detach=false mycentos:1.0 ping 192.168.192.111
8、docker service ls
9、docker ps
10、docker exec -it f68 sh
ping nginx
11、docker service ls
12、docker service ps apline
13、docker service create --name nginx-b --endpoint-mode dnsrr --detach=false nginx
13、docker service ps apline
14、docker service update --network-add drunk-overlay --detach=false nginx-b
15、docker service ls
16、docker service rm apline nginx nginx-b

三、docker stack
1、service.yml
version: “3.4”
services:
mycentos:
image: registry.cn-qingdao.aliyuncs.com/dqdocker/mycentos:1.0
command:

• “ping”
• “www.baidu.com”
  networks:
• “drunk-overlay”
  deploy:
  endpoint_mode: dnsrr
  replicas: 2
  restart_policy:
  condition: on-failure
  resources:
  limits:
  cpu: “0.1”
  memory: 50M
  depends_on:
• nginx
  nginx:
  image: nginx
  networks:
• “drunk-overlay”
  ports:
• “8080:80”
  networks:
  drunk-overlay:
  external: true
  2、docker stack deploy -c service.yml test
  3、docker service ls
  4、docker service ps test_apline
  5、docker ps
  6、docker exec -it 3fa sh

7、docker service
8、docker service scale ms_api-gateway=3
10、docker service update ms_api-gateway --limits-cpu 0.5 --detach=false
