篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了docker swarm service服务端口的问题相关的知识，希望对你有一定的参考价值。
参考技术A docker swarm service服务端口的问题当我们使用 docker service create --publish <PUBLISHED-PORT>:<SERVICE-PORT> 创建服务的时候，端口会监听在哪里？
答案是会监听在swarm网络上的所有node上。
举例来说：
假如我们有5台主机：vm1, vm2, vm3,vm4,和vm5
其中manager是vm1，vm2，vm3
worker是vm4，和vm5
当我们在任何一台manager主机上创建service时，假设--replicas=2，例如：
这样swarm会在5台vm上任选两台主机，创建两个continers，他们可能在manager节点上，也可能在worker节点上，随机分配。
但是published的8080端口会监听在所有的5台vm上，可以使用任意vm[1-5]:8080地方来访问nginx，例如：
达到同样的效果。
另外由于我们创建了两个container，那么具体哪一个contaier提供服务呢？docker swarm使用round robin的策略：第一个请求达到container1，第二个请求到container2，下一个再到container1，然后下下一个到contiainer2，如此轮询。
如果在my-overlay-network里面，用户也可以使用 curl http://service-name:80/ 来访问nginx，然后在container层面，还是使用轮询的方式。
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：
