部署使用

shell 复制代码 
# 重新初始化集群，都要操作
root@133:~# systemctl stop docker
root@133:~# rm -rf /var/lib/docker/swarm/
root@133:~# docker swarm init --advertise-addr 10.1.0.133 --default-addr-pool 192.20.0.0/16

root@133:~# docker swarm join-token manager
    docker swarm join --token SWMTKN-1-54wnqxi04uwboi3h 10.1.0.133:2377

root@133:~# docker network create -d overlay --subnet=192.20.100.0/24 --attachable my_external_network

root@133:~# docker node ls
ID                            HOSTNAME   STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
zbag3oxp2jlkv7f8xdintn7kr *   133        Ready     Active         Leader           27.5.1
vglj81ajcdco23d3995rgrm7t     134        Ready     Active         Reachable        27.5.1

使用yaml部署

创建时，服务名生成格式 {默认stack名}_{service名}

shell 复制代码 
root@133:~# cat nginx1.yaml
services:
  app:
    image: nginx
    deploy:
      replicas: 2
      resources:
        limits:
          cpus: '0.5'
          memory: 512M
      update_config:
        parallelism: 1
        delay: 10s
        failure_action: pause
        order: start-first
    ports:
      - "18080:80"
    networks:
      - my_external_network
networks:
  my_external_network:
    external: true

root@133:~# docker stack deploy -d -c nginx1.yaml web1
Creating service web1_app

root@133:~# docker service ls

gwkltslf7f3b   web1_app   replicated   2/2        nginx:latest   *:18080->80/tcp

yaml示例2

shell 复制代码 
root@133:~# cat nginx2.yaml
services:
  app:
    image: nginx
    ports:
      - "28080:80"
    volumes:

    environment:

    extra_hosts:
      - "www.byd.com:10.1.0.133"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost"]
      interval: 1m
      timeout: 10s
      retries: 3
      start_period: 40s
    deploy:
      replicas: 2
      resources:
        limits:
          cpus: '0.5'
          memory: 512M
      update_config:
        parallelism: 1
        delay: 10s
        failure_action: pause
        order: start-first
    networks:
      - my_external_network
networks:
  my_external_network:
    external: true

root@133:~# docker service rm web2_app
web2_app
root@133:~# docker stack deploy -d -c nginx2.yaml web2
Creating service web2_app

# 创建时，服务名生成格式 {默认stack名}_{service名}

多次启动失败后，容器会自动更换节点

shell 复制代码 
# 因为134为创建 /mnt/test1/目录，挂载报错，不会自动创建

网络访问

shell 复制代码 
root@133:~# docker ps |grep 28080 #不显示的
root@133:~# curl localhost:28080
hello test1
root@133:~# curl 10.1.0.134:28080
hello test1

历史版本保存与清理

shell 复制代码 
# 更新镜像，旧的镜像会以Exited存在，这里测试，默认保留了五个，暂时没查到保留的参数

#  直接删除stack会清理相关的 Exited容器
root@133:~# docker service rm web2_app
web2_app
root@133:~# docker ps -a |grep web2_app # 会自动删除
shell 复制代码 
##   拉取私有镜像 --with-registry-auth
root@133:~# docker service update --image  my.docker.com/ubuntu:22.04ssh --with-registry-auth web2_app

portainer-ce管理工具使用

shell 复制代码 
portainer/portainer-ce:2.33.2
portainer/agent:2.33.2

root@133:~# docker run -d -p 9000:9000   --name portainer --restart=always   -v /var/run/docker.sock:/var/run/docker.sock -v ./portainer_data:/data  portainer/portainer-ce:2.33.2

docker service create \
  --name portainer_agent \
  --network my_external_network \
  -p 9001:9001/tcp \
  --mode global \
  --constraint 'node.platform.os == linux' \
  --mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock \
  --mount type=bind,src=//var/lib/docker/volumes,dst=/var/lib/docker/volumes \
  --mount type=bind,src=//,dst=/host \
  portainer/agent:2.33.2
  
在Environment-related选项  add Environment -->docker swarm --start wizard--> agent/api-2375访问，也可portainer/agent。
添加多个2375时，多swarm集群，在home页可以看到多个swarm集群
