我已经使用 minukube 制作了我的集群。
据我所知，索引作业功能是在 kubernetes 版本1.21中添加的。
但是当我完成工作时，似乎没有 $JOB_COMPLETION_INDEX 环境变量。
这是我的 yaml
apiVersion: batch/v1
kind: Job
metadata:
name: my-job
spec:
parallelism: 2
completions: 2
completionMode: Indexed
template:
spec:
restartPolicy: Never
containers:
- name: 'my-container'
image: 'busybox'
command: [
"sh",
"-c",
"echo My Index is $JOB_COMPLETION_INDEX && sleep 3600",
]
$ job.batch/my-job created
但正如我之前提到的，看起来这份工作不是索引工作
下面是我的豆荚的日志（由我的工作控制）
$ kubectl logs pod/my-job-wxhh6
My Index is
$ kubectl logs pod/my-job-nbxkr
My Index is
$JOB_COMPLETION_INDEX环境变量似乎为空。
我将跳过它以使其简短，但是当我直接访问容器时，也没有 $JOB_COMPLETION_INDEX。
以下是kubectl describe job.batch/my-job 命令的结果
Name: my-job

没有注释。作为文档，batch.kubernetes.io/job-completion-index注释必须存在。
我的版本高于 kubernetes 1.21，其中引入了 Indexed-Job 功能。

我应该怎么办？
