配置BCI Pod访问集群内Service
更新时间：2025-02-26
概述
BCI支持从BCI实例中访问K8S ClusterIP类型Service。如果您需要在BCI实例中访问集群中ClusterIP, 您需要在Pod Spec Yaml中添加如下Annotation，用于开启功能:
bci.virtual-kubelet.io/kube-proxy-enabled: true
Annotation 请添加在Pod的metadata下，例如：创建Deployment时，Annotation需添加在spec>template>metadata下。 仅支持在创建BCI Pod时添加BCI相关Annotation来生效BCI功能，已成功的BCI Pod只能重建来生效。
配置示例
以创建一个简单的Nginx为例，Nginx的Pod 会调度到VNode上：
