Kubernetes-如何只运行一次作业 [英] Kubernetes - how to run job only once

问题描述

我有一个基于kubernetes网站上的示例的职位定义.

I have a job definition based on example from kubernetes website.

apiVersion: batch/v1
kind: Job
metadata:
  name: pi-with-timeout-6
spec:
  activeDeadlineSeconds: 30
  completions: 1
  paralleism: 1
  template:
    metadata:
      name: pi
    spec:
      containers:
      - name: pi
        image: perl
        command: ["exit", "1"]
      restartPolicy: Never

我想运行一次此作业，如果失败则不要重新启动.使用comand出口1时，kubernetes尝试运行新的pod以获得出口0代码，直到达到activeDeadlineSeconds超时.如何避免这种情况?我想在kubernetes中运行构建命令来检查编译，如果编译失败，我将获得不同于0的退出代码.我不想再次运行编译.

I would like run this job once and not restart if fails. With comand exit 1 kubernetes trying to run new pod to get exit 0 code until reach activeDeadlineSeconds timeout. How can avoid that? I would like run build commands in kubernetes to check compilation and if compilation fails I'll get exit code different than 0. I don't want run compilation again.

有可能吗?怎么样?

推荐答案

如果您希望使用一次尝试的命令运行程序，则可能应该创建裸机舱，因为该作业将尝试执行命令，直到成功或有效期限为止被满足.

If you want a one-try command runner, you probably should create bare pod, because the job will try to execute the command until it's successful or the active deadline is met.

只需从您的模板创建广告连播:

Just create the pod from your template:

apiVersion: v1
kind: Pod
metadata:
  name: pi
spec:
  containers:
  - name: pi
    image: perl
    command: ["exit", "1"]
  restartPolicy: Never
