K8s-Pod重启策略

以下是一些常见的Kubernetes Pod重启策略示例

一、Always
无论何时容器退出，Kubernetes都会自动重启该容器。

apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
restartPolicy: Always
containers:

• name: my-container
  image: my-image
  command: ["my-command"]

二、OnFailure
当容器以非零状态退出时，Kubernetes将重启该容器

apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
restartPolicy: OnFailure
containers:

• name: my-container
  image: my-image
  command: ["my-command"]

三、Never
当容器退出时，Kubernetes将不会自动重启该容器

apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
restartPolicy: Never
containers:

• name: my-container
  image: my-image
  command: ["my-command"]

四、在deployment文件指定容器的重启策略
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-deployment
spec:
replicas: 3
selector:

matchLabels:
  app: my-app

template:

metadata:
  labels:
    app: my-app
spec:
  restartPolicy: Always
  containers:
  - name: my-container
    image: my-image
    command: ["my-command"]
