我有一个pod，它发出指标，它有多个出口相关联，如-
1.身份验证端点（tcp/443）
1.域名系统（UDP/53）
1.示例元数据（tcp/80）
1.其他pod（全部）

为上述所有内容定义策略的好做法是什么-

1 -单个网络策略中的所有出口
示例（所有出口采用相同策略）

apiVersion: networking.k8s.io/v1
    kind: NetworkPolicy
    metadata:
      name: metrics-emitter-egress-to-multiple-points
    spec:
      podSelector:
        matchLabels:
          name: metrics-emitter
      policyTypes:
      - Egress
      egress:
      - to:
        - ipBlock:
            cidr: 0.0.0.0/0
        ports:
        - protocol: TCP
          port: 443
      - to:
        ports:
        - protocol: UDP
          port: 53
      - to:
        - ipBlock:
            cidr: 0.0.0.0/0
        ports:
        - protocol: TCP
          port: 9443

或
2 -每个出口使用不同的NetworkPolicy
示例（每个NetPol不同）-

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: metrics-emitter-egress-to-auth-endpoint
spec:
  podSelector:
    matchLabels:
      name: metrics-emitter
  policyTypes:
  - Egress
  egress:
  - to:
    - ipBlock:
        cidr: 0.0.0.0/0
    ports:
    - protocol: TCP
      port: 443
