无法将 Vagrant 机器连接到桥接网络答案

【问题标题】：Unable to connect Vagrant machine to bridged network无法将 Vagrant 机器连接到桥接网络

【问题描述】：

我的主机上运行了多个 docker 容器，默认情况下，所有这些容器都可以通过 Docker 自动创建的名为 docker0 的桥接网络中的主机名（即容器名称）访问。

除了 docker 容器，我还有两个使用 Vagrant 创建的虚拟机。我想将这两个虚拟机添加到 docker 中，这样它们就可以在没有端口转发的情况下与 docker 容器通信。

这是我为一台虚拟机配置的 Vagrant：

  config.vm.define :master1 do |m1|
    m1.vm.hostname = "master1.mycluster"
    # m1.vm.network :private_network, ip: "192.168.0.12"
    m1.vm.network :public_network, bridge:"docker0"
    m1.vm.provider :virtualbox do |vb|
      vb.memory = "4596"
    end
  end

这是 vagrant up 的输出：

==> master1: Attempting graceful shutdown of VM...
==> master1: Checking if box 'bento/centos-6.7' is up to date...
==> master1: Clearing any previously set forwarded ports...
==> master1: Fixed port collision for 22 => 2222. Now on port 2201.
==> master1: Clearing any previously set network interfaces...
==> master1: Preparing network interfaces based on configuration...
    master1: Adapter 1: nat
    master1: Adapter 2: bridged
==> master1: Forwarding ports...
    master1: 22 (guest) => 2201 (host) (adapter 1)
==> master1: Running 'pre-boot' VM customizations...
==> master1: Booting VM...
==> master1: Waiting for machine to boot. This may take a few minutes...
    master1: SSH address: 127.0.0.1:2201
    master1: SSH username: vagrant
    master1: SSH auth method: private key
    master1: Warning: Remote connection disconnect. Retrying...
    master1: Warning: Remote connection disconnect. Retrying...
    master1: Warning: Remote connection disconnect. Retrying...
    master1: Warning: Remote connection disconnect. Retrying...

    master1: Warning: Remote connection disconnect. Retrying...
==> master1: Machine booted and ready!
==> master1: Checking for guest additions in VM...
==> master1: Setting hostname...
==> master1: Configuring and enabling network interfaces...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

ARPCHECK=no /sbin/ifup eth1 2> /dev/null

Stdout from the command:


Determining IP information for eth1... failed.


Stderr from the command:

有关信息，这是我主机上的 ifconfig：

docker0   Link encap:Ethernet  HWaddr 02:42:68:a8:70:ec  
          inet addr:172.17.0.1  Bcast:0.0.0.0  Mask:255.255.0.0

你能解释一下是什么问题吗？谢谢。

【解决方案1】：

172.17.0.1 始终被归类为私有内部 IP 地址。这就像在您的 VM 中点击 localhost/127.0.0.1 并期望点击主机。

你可以做任何你想做的事，this 链接非常清楚。
