azure - 在 Azure 但在非 AKS Kubernetes 环境/Kubernetes Baremetal 安装中需要 Azure CNI 的问题或帮助

问题描述

我找到了这个 cni 和插件，我目前正在使用 docker 在 azure 上的 kubernetes v1.20.5 裸机安装中对其进行测试。我们不使用 aks azure 服务，因为我们想在我们的一个客户的 prem vmware 环境中学习和部署以后的 kubernetes，但是我们会在那里使用不同的 cni，比如 flannel 或 weave。flannel 和 weave 在 azure 上不起作用，这就是我使用 azure cni 插件的原因。

我的测试环境：

我下面的 ipam 配置无法正常工作。我需要添加第二个网卡

{
   "cniVersion":"0.3.0",
   "name":"azure",
   "plugins":[
      {
         "type":"azure-vnet",
         "mode":"transparent",
         "ipsToRouteViaHost":["169.254.20.10"],
         "ipam": {
           "type": "host-local",
           "subnet": "10.1.0.0/16",
           "gateway": "10.1.0.1"
         },
         "dns": {
           "nameservers": [ "10.1.0.1" ]
         }
      },
      {
         "type":"portmap",
         "capabilities":{
            "portMappings":true
         },
         "snat":true
      }
   ]
}

以下是我的问题：

  1. 我的配置在顶部吗？还是我理解错了？
  2. 这仅在我将 azure 上的多个 ip 地址添加到第二个 nic（eth1，子网 10.1.0.0/16）时才有效，但我希望有所不同。但我不想那样做！！！:-(
  3. 如果我对您的文档的理解正确，我希望该插件会在第二个 nic 上创建、添加和删除 ipadresses？

如果有人能帮助我，我将非常感激，因为我正在慢慢发疯^^

提前谢谢
