restartPolicy：不支持的值：“从不”：支持的值：“始终”

Question

我的广告连播具有以下配置：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: my-app
  labels:
    app: my-app
spec:
  serviceName: my-app
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      restartPolicy: Never
      containers:
      - name: my-app
        image: myregistry:443/mydomain/my-app
        imagePullPolicy: Always

And it deploys fine without the restartPolicy. However, I do not want the process to be run again once finished, hence I added the 'restartPolicy: Never'. Unfortunately I get the following error when I attempt to deploy:

Error from server (Invalid): error when creating "stack.yaml": StatefulSet.apps "my-app" is invalid: spec.template.spec.restartPolicy: Unsupported value: "Never": supported values: "Always"

What am I missing?

Thanks

您应该使用作业控制器而不是 StatefulSet：

一个 Job 创建一个或多个 Pod，并确保指定数量的 Pod 成功终止。当 pod 成功完成时，Job 会跟踪成功完成情况。

查看处理 Pod 和容器故障部分，该部分解释了使用restartPolicywith 值OnFailure或Never与其他配置（例如parallelism,completions和 ）相结合的效果backoffLimit。

请参阅https://github.com/kubernetes/kubernetes/issues/24725

似乎仅支持“始终”。
