Docker Swarm 入门示例4: 检视swarm服务信息

1. 打开manager1服务器 shell

2. 查看服务详细信息 命令： docker service inspect --pretty <SERVICE-ID>

   $ docker service inspect --pretty helloworld
   
   ID:             fqfl3lzv87dikpys0cuek7u72
   Name:           helloworld
   Service Mode:   Replicated
    Replicas:      1
   Placement:
   UpdateConfig:
    Parallelism:   1
    On failure:    pause
    Monitoring Period: 5s
    Max failure ratio: 0
    Update order:      stop-first
   RollbackConfig:
    Parallelism:   1
    On failure:    pause
    Monitoring Period: 5s
    Max failure ratio: 0
    Rollback order:    stop-first
   ContainerSpec:
    Image:         alpine:latest@sha256:ccba511b1d6b5f1d83825a94f9d5b05528db456d9cf14a1ea1db892c939cda64
    Args:          ping baidu.com
   Resources:
   Endpoint Mode:  vip
   
   

   如果需要返回json结果则去掉 --pretty

3. 查看服务运行节点 命令： docker service ps <SERVICE-ID>

   $ docker service ps helloworld
   ID                  NAME                IMAGE               NODE                DESIRED STATE       CURRENT STATE            ERROR                       PORTS
   i55lyst49m5t        helloworld.1        alpine:latest       ubuntu-1604-001     Running             Running 10 minutes ago
   b1h5uai64w51         \_ helloworld.1    alpine:latest       ubuntu-1604-003     Shutdown            Failed 10 minutes ago    "task: non-zero exit (1)"
   

4. 查看容器运行详情 打开对应节点shell 命令： docker ps

   $ docker ps
   CONTAINER ID        IMAGE                                                                 COMMAND                  CREATED             STATUS                          PORTS                    NAMES
   5d2d0a2d73c9        alpine:latest                                                         "ping baidu.com"         13 minutes ago      Up 13 minutes                                            helloworld.1.i55lyst49m5tsca49qicalc3m
