在kubernetes中使用weave虚拟网络，在nat后面使用weave pod

我想在NAT后面的节点中部署带有编织虚拟网络的kubernetes集群 . （例如，在openstack中使用浮动IP）

这是一个例子：

Kube Master：编织pod在这里运行

  • 内部IP：192.168.0.10

  • 外部IP：172.10.0.10

Kube节点（ Worker ）

  • 内部IP：172.10.0.11

在kube节点（worker）上运行的pod中的日志如下所示：

kubernetes集群已正确配置，广告地址为：172.10.0.10

kubernetes nat weave

    我目前的解决方法是修复编织配置文件中节点的IP：

    wget https://git.io/weave-kube-1.6      
vim weave-kube-1.6

    并使用您的IP修改它

    containers:
    - name: weave
      env:
      - name: KUBE_PEERS
        value: "172.10.0.10 172.10.0.11"
