ReadinessProbe + LivenessProbe 配合使用示例

一般程序中需要设置两种探针结合使用，并且也要结合实际情况，来配置初始化检查时间和检测间隔，下面列一个简单的 SpringBoot 项目的 Deployment 例子。

apiVersion: v1
kind: Service
metadata:
  name: springboot
  labels:
    app: springboot
spec:
  type: NodePort
  ports:
  - name: server
    port: 8080
    targetPort: 8080
    nodePort: 31180
  - name: management
    port: 8081
    targetPort: 8081
    nodePort: 31181
  selector:
    app: springboot
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: springboot
  labels:
    app: springboot
spec:
  replicas: 1
  selector:
    matchLabels:
      app: springboot
  template:
    metadata:
      name: springboot
      labels:
        app: springboot
    spec:
      containers:
      - name: readiness
        image: mydlqclub/springboot-helloworld:0.0.1
        ports:
        - name: server 
          containerPort: 8080
        - name: management
          containerPort: 8081
        readinessProbe:
          initialDelaySeconds: 20 
          periodSeconds: 5      
          timeoutSeconds: 10        
          httpGet:
            scheme: HTTP
            port: 8081
            path: /actuator/health
         livenessProbe:
            initialDelaySeconds: 30 
            periodSeconds: 10 
            timeoutSeconds: 5 
            httpGet:
              scheme: HTTP
              port: 8081
              path: /actuator/health
