Docker Swarm和私有IP [英] Docker Swarm and private IP

问题描述

当我通过docker启动应用程序时，可以在指定IP的端口上发布该应用程序。

When I launch an app via docker I can publish the app on a port specifying the IP.

假设我的服务器有两个IP（专用192.168.0.2和公用200.168.0.2），我可以使用以下命令在专用ip上公开一个应用程序：

Suppose that my server has two ip (private 192.168.0.2 and public 200.168.0.2), I can expose an app on the private ip with this command:

  docker run -it -p 192.168.0.2:80:80 nginx 

如何使用docker swarm实现类似的目标？

How can I achieve something similar with docker swarm?

我想我必须首先创建一个docker网络层，但是我不知道正确的语法是什么。

I guess I must create a docker network layer first, but I don't understand what the right syntax is.

基本上我想做类似的事情：

Basically I would like to do something similar:

    docker network create \
      --driver overlay \
      --IP 192.168.0.2 \
      --IP 192.167.0.1 \
      private_net

    docker service create --replicas 2 \ 
    --network private_net --name my-web nginx

其中192.168.0.2和192.167.0.1是群集集群服务器的IP。

Where 192.168.0.2 and 192.167.0.1 are the IPs of the swarm cluster servers.

推荐答案

Swarm不提供在特定接口上侦听的选项，默认为在所有接口上监听。这是未解决的问题。在docker内部修改覆盖网络不会更改此行为。

Swarm doesn't give the option to listen on a specific interface, it defaults to listen on all interfaces. This is an open issue. Modifying overlay networks inside of docker will not change this behavior.
