简单记录kubernetes 新增的startup Probe

一旦启动探针探测成功之后，就会被livenessProbe接管，以下是1.17支持的三种probe example

apiVersion: v1
kind: Pod
metadata:
  name: goproxy
  labels:
    app: goproxy
spec:
  containers:
  - name: goproxy
    image: nginx:1.9
    ports:
    - containerPort: 8080
    readinessProbe:
      tcpSocket:
        port: 8080
      initialDelaySeconds: 5
      periodSeconds: 10
    livenessProbe:
      exec:
        command:
        - cat
        - /tmp/healthy
    livenessProbe:
      tcpSocket:
        port: 8080
      initialDelaySeconds: 15
      periodSeconds: 20
    livenessProbe:
      httpGet:
        path: /healthz
        port: liveness-port
      failureThreshold: 1
      periodSeconds: 10
    ports:
    - name: liveness-port
      containerPort: 8080
      hostPort: 8080
    startupProbe:
      httpGet:
        path: /healthz
        port: liveness-port
      failureThreshold: 30
      periodSeconds: 10
