通过使用GNU timeout 实用程序在容器的入口点命令上设置超时。

You can self-impose timeouts on the container's entrypoint command by using GNU timeout utility.

例如，以下计算作业pi的前4000个数字将在10秒后超时：

For example the following Job that computes first 4000 digits of pi will time out after 10 seconds:

apiVersion: batch/v1
kind: Job
metadata:
  name: pi
spec:
  template:
    metadata:
      name: pi
    spec:
      containers:
      - name: pi
        image: perl
        command: ["/usr/bin/timeout", "10", "perl", "-Mbignum=bpi", "-wle", "print bpi(4000)"]
      restartPolicy: Never

您可以玩这些数字，看看是否超时。通常，计算4000位数的pi在我的工作站上大约需要23秒，因此，如果将其设置为5秒，它可能总是会失败，而如果将其设置为120秒，它将总是可以工作。

You can play with the numbers and see it timeout or not. Typically computing 4000 digits of pi takes ~23 seconds on my workstation, so if you set it to 5 seconds it'll probably always fail and if you set it to 120 seconds it will always work.
