红帽全球峰会第 5 章 保护服务网络
skupper 提供默认的内置安全性，可在集群和云中扩展。本节论述了您可以配置的其他安全性。
如需有关 为每个集群创建粒度策略的信息，请参阅使用策略保护 服务网络。
5.1. 使用 Kubernetes 网络策略限制对服务的访问

默认情况下，如果您在服务网络上公开服务，该服务也可以从集群中的其他命名空间访问。您可以使用 --create-network-policy 选项创建站点时避免这种情况。
流程
使用 Kubernetes 网络策略创建服务网络路由器：
skupper init --create-network-policy
$ skupper init --create-network-policyCopy to Clipboard Copied! Toggle word wrap Toggle overflow 检查站点状态：
skupper status
$ skupper statusCopy to Clipboard Copied! Toggle word wrap Toggle overflow 输出应类似于如下：
Skupper enabled for namespace 'west'. It is not connected to any other sites.
Skupper enabled for namespace 'west'. It is not connected to any other sites.Copy to Clipboard Copied! Toggle word wrap Toggle overflow
现在，您可以在服务网络上公开服务，这些服务无法从集群中的其他命名空间访问。
