Kubernetes：如何创建入口类型网络策略以仅允许访问带标签的 pod

问题描述

我有以下@H_502_1@deployment

@H_502_1@apiVersion: apps/v1
kind: Deployment
Metadata:
  creationTimestamp: null
  labels:
    app: redis
  name: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  strategy: {}
  template:
    Metadata:
      creationTimestamp: null
      labels:
        app: redis
    spec:
      containers:
      - image: redis:alpine
        name: redis
        resources: {}
status: {}

问题 1：您如何通过端口 8080 上的 @H_502_1@ClusterIP 服务公开此部署。

问题 2 ：我将如何创建新的入口类型 @H_502_1@NetworkPolicy 以仅允许带有标签 @H_502_1@access=redis 的 Pod 访问部署。

解决方法

服务

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  selector:
    app: redis
  ports:
    - protocol: TCP
      port: 8080
      targetPort: 6379

网络政策

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: test-network-policy
spec:
  podSelector:
    matchLabels:
      app: redis
  policyTypes:
  - Ingress
  ingress:
  - from:
    - podSelector:
        matchLabels:
          access: redis
    ports:
    - protocol: TCP
      port: 6379
