Docker swarm 获取service的container信息
我们可以通过docker service create创建服务，例如：
docker service create --name mysql mysql:latest
服务创建好后，如何来获取该service包含的容器信息呢？比如获取刚才创建的mysql服务的容器。我们可以通过docker service ps命令来获取，
命令行方式
~# docker service ps mysql
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
lvskmv1lkhz6 mysql.1 mysql:latest docker86-9 Running Running 3 days ago
遗憾的是返回的数据不包含containerId，只有serviceId, 可以通过docker inspect来获取service详情
~# docker inspect lvskmv1lkhz6

返回的json中，NodeID是所在节点ID，Status.ContainerStatus 是容器的状态信息，.Status.ContainerStatus.ContainerID 是容器ID，比如这里的是2cf128f77797f08419f50a057973388f15753efb16134ed05370ded495d0ac08。
拿到容器ID就能获取容器详情了，也可以获取container的统计信息：

然后就可以通过stats来获取资源占用情况：
~#docker stats 2cf128f77797f08419f50a057973388f15753efb16134ed05370ded495d0ac08 --all --no-stream

coding方式
除了命令行，我们还可以通过docker api来获取，可以参见 docker-java Docker的java API
获取containerID
System.out.println(client.listTasksCmd().withNameFilter("mysql").exec());
结果：

可以看到containerID：2cf128f77797f08419f50a057973388f15753efb16134ed05370ded495d0ac08 和命令行一直。
然后获取容器详情：
System.out.println(client.inspectContainerCmd("2cf128f77797f08419f50a057973388f15753efb16134ed05370ded495d0ac08").exec());
获取容器统计信息：
