Docker端口转发不起作用 [英] Docker port forwarding not working

问题描述

我已经设置了Docker容器，以便将我的机器docker容器访问本地的另一台机器.

在命令下方创建一个容器:

    docker run -it -d --name containerName -h www.myhost.net -v /var/www/html -p 7000:8000 --net mynetwork --ip 172.11.0.10 --privileged myimagename bash

创建容器详细信息后:

        CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES

        1e1e5e9b74b4        myimgaename         "bash"              21 minutes ago      Up 6 minutes        0.0.0.0:7000->8000/tcp   containername

网络详细信息:

     "NetworkSettings": {
        "Bridge": "",
        "SandboxID": "fe357c54c816fff0f9d642037dc9a173be7f7e42a80776d006572f6a1395969e",
        "HairpinMode": false,
        "LinkLocalIPv6Address": "",
        "LinkLocalIPv6PrefixLen": 0,
        "Ports": {
            "8000/tcp": [
                {
                    "HostIp": "0.0.0.0",
                    "HostPort": "7000"
                }
            ]
        }

如果我在mymachine(hostmachine)中访问docker ipaddr(172.11.0.10)或主机名(www.myhost.net)，则它正常工作

但是如果我使用端口访问不起作用:主机ip:192.168.1.1

  go to the browser  192.168.1.1:7000  hostmachine and locally connected anoter machine also.

但是我的7000端口在主机中监听:

        # ps aux | grep 7000
        root     10437  0.0  0.2 194792 24572 pts/0    Sl+  12:33   0:00 docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 7000 -container-ip 172.11.0.10 -container-port 8000
        root     10941  0.0  0.0 118492  2324 pts/3    R+   12:44   0:00 grep --color=auto 7000

建议我为什么无法将我的容器访问另一台机器.如何解决这个问题

解决方案

一个很常见的问题可能是:

将您的应用绑定到Docker中的 0.0.0.0 ，而不是 127.0.0.1 地址，以使Docker到达容器内的应用. /p>

I have setup Docker container for access my machine docker container to another machine in local.

Create a container below command:

    docker run -it -d --name containerName -h www.myhost.net -v /var/www/html -p 7000:8000 --net mynetwork --ip 172.11.0.10 --privileged myimagename bash

After Create A Container Details:

        CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES

        1e1e5e9b74b4        myimgaename         "bash"              21 minutes ago      Up 6 minutes        0.0.0.0:7000->8000/tcp   containername

NetWork Details:

     "NetworkSettings": {
        "Bridge": "",
        "SandboxID": "fe357c54c816fff0f9d642037dc9a173be7f7e42a80776d006572f6a1395969e",
        "HairpinMode": false,
        "LinkLocalIPv6Address": "",
        "LinkLocalIPv6PrefixLen": 0,
        "Ports": {
            "8000/tcp": [
                {
                    "HostIp": "0.0.0.0",
                    "HostPort": "7000"
                }
            ]
        }

if I access docker ipaddr(172.11.0.10) or hostname(www.myhost.net) in mymachine(hostmachine) it working

But if I access with Port doesn't work: hostmachine ip: 192.168.1.1

  go to the browser  192.168.1.1:7000  hostmachine and locally connected anoter machine also.

But My 7000 port are listen in hostmachine:

        # ps aux | grep 7000
        root     10437  0.0  0.2 194792 24572 pts/0    Sl+  12:33   0:00 docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 7000 -container-ip 172.11.0.10 -container-port 8000
        root     10941  0.0  0.0 118492  2324 pts/3    R+   12:44   0:00 grep --color=auto 7000

update 1:

      $ docker version
        Client:
         Version:      1.11.2
         API version:  1.23

Suggest me Why Cannot access my Container to another machine. How to Resolve this Problem

解决方案

A very common problem can be this:

Bind your app inside Docker to 0.0.0.0, not to 127.0.0.1 address to let Docker reach the app inside container.
