红帽全球峰会6.6. networkPolicyPeers
使用 networkPolicyPeers 来配置网络策略，以限制对网络级别的监听程序的访问。以下示例显示了 普通 和 tls 侦听器的 networkPolicyPeers 配置。
在以下示例中：
-
只有与标签
app: kafka-sasl-consumer和app: kafka-sasl-producer匹配的应用程序 pod 可以连接到纯文本。应用程序 pod 必须与 Kafka 代理在同一命名空间中运行。 -
只有在与标签
project: myprojectandproject: myproject2的命名空间中运行的应用程序 pod 才可以连接到tls侦听程序。
networkPolicyPeers 属性的语法与 NetworkPolicy 资源中的 from 属性相同。
