在声明网络策略的文档的基本示例中: https ://kubernetes.io/docs/concepts/services-networking/network-policies/#the-networkpolicy-resource
因此,根据文档,这设置了几条规则:
So, the example NetworkPolicy:
- isolates “role=db” pods in the “default” namespace for both ingress
and egress traffic (if they weren’t already isolated)
- allows connections to TCP port 6379 of “role=db” pods in the “default”
namespace from any pod in the “default” namespace with the
label “role=frontend”
- allows connections to TCP port 6379 of “role=db” pods
in the “default” namespace from any pod in a namespace with
the label “project=myproject”
...
这是否意味着“role=db”标签的 pod 可以从以下位置接收连接:
- 其他标签为“role=frontend”和命名空间标签为“project=myproject”的pod;或者
- 其他标签为“role=frontend”或命名空间标签为“project=myproject”的pod。
谢谢!
