18、k8s-pod的生命周期-重启策略（Always、OnFailure、Nerver）

 

实例：容器如果探测、获取不到http地址的话、让容器不再尝试重启（Nerver）

1、新建yaml文件：vim pod-restartpolicy.yaml
==========================
apiVersion: v1
kind: Pod
metadata:
 name: pod-restartpolicy
 namespace: dev

spec:
 containers:
 - name: nginx
   image: nginx:1.17.1
   ports:
   - name: nginx-port
     containerPort: 80
   livenessProbe:
     httpGet:
      scheme: HTTP
      port: 80
      path: /hello
 restartPolicy: Never    #设置重启策略为nerver    与containers同级
===================================
2、执行文件创建pod：kubectl create -f pod-restartpolicy.yaml
3、动态查看pod状态：kubectl get pod pod-restartpolicy -ndev -w

4、kubectl describe pod pod-restartpolicy -ndev
