容器服务ACK之前创建的集群，只添加了深圳E可用区的交换机，现在想把深圳ABCDF的交换机都加进去

在容器服务ACK（阿里云容器服务Kubernetes版）中，我们可以使用VPC网络插件来管理集群的网络，当我们创建一个集群时，可以选择一个或多个可用区，并为每个可用区选择一个交换机，如果我们在创建集群时只添加了一个可用区的交换机，那么在后续的使用过程中，我们可能会发现需要将其他可用区的交换机也加入到集群中，本文将介绍如何在容器服务ACK中将深圳ABCDF的交换机都加进之前创建的集群。

1. 了解VPC网络插件

在容器服务ACK中，VPC网络插件是一个可选的网络插件，它允许我们在创建集群时选择自定义的VPC和交换机，通过使用VPC网络插件，我们可以为集群提供更灵活的网络配置。

2. 查看当前集群的网络配置

在开始操作之前，我们需要先查看当前集群的网络配置，可以通过以下命令查看：

kubectl get svc n kubesystem

这个命令会显示当前集群中所有与网络相关的服务，包括负载均衡器、Ingress控制器等，从这些服务的输出中，我们可以了解到当前集群使用的网络插件、网络策略等信息。

3. 修改集群的网络配置

要为集群添加新的交换机，我们需要修改集群的网络配置，我们需要获取当前集群的网络配置文件：

kubectl get cm n kubesystem kubeproxyconfig oyaml > kubeproxyconfig.yaml

我们需要编辑kubeproxyconfig.yaml文件，将spec.podSubnets字段中的cidrBlocks列表更新为包含新交换机CIDR的列表，如果深圳ABCDF的交换机CIDR分别为10.0.0.0/16、10.1.0.0/16、10.2.0.0/16、10.3.0.0/16和10.4.0.0/16，那么我们需要将这些CIDR添加到spec.podSubnets字段中：
