k8s - livenessProve - httpGet 存活性探測

[root@k8s-master01 k8s-test]# cat livenessProbe-httpget.yaml 
apiVersion: v1
kind: Pod
metadata:
  name: liveness-httpget-pod
  namespace: default
spec:
  containers:
  - name: liveness-httpget-container
    image: kone.com/library/nginx
    imagePullPolicy: IfNotPresent
    ports:
    - name: http
      containerPort: 80
    livenessProbe:
      httpGet:
        port: http

      initialDelaySeconds: 1
      periodSeconds: 3

[root@k8s-master01 k8s-test]# 

創建kubectl create -f livenessProbe-httpget.yaml
查看此時重啓次數爲0

[root@k8s-master01 k8s-test]# kubectl get pod
NAME                               READY   STATUS             RESTARTS   AGE
liveness-httpget-pod               1/1     Running            0          4m31s

進入容器刪除/usr/share/nginx/html/index.htm
kubectl exec -it liveness-httpget-pod -- rm -f /usr/share/nginx/html/index.html
然後看容器的重啓次數爲1

[root@k8s-master01 k8s-test]# kubectl get pod -w
NAME                               READY   STATUS    RESTARTS   AGE
liveness-httpget-pod               1/1     Running   1          7m25s
