k 8 s nginx健康診断機能の導入(生存プローブ)

1、k 8 sはnginxのyamlファイル1.1を配備し、nginx健康診断はtcpSocketを使用する:方式

[root@k8s-node1 yaml_file]# cat nginx_lp.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mynginx
spec:
  replicas: 1

          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 80
          livenessProbe:
            tcpSocket:
              port: 80
            initialDelaySeconds: 45   #pod   45s        
            periodSeconds: 15       #        15s

          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 80
          livenessProbe:
            httpGet:
              path: /
              port: 80
            initialDelaySeconds: 10
