Kubernetes CronJob - 多个 CronJob 配置不起作用

Question

我必须运行 Kubernetes (AWS-EKS) 中的两个 CronJobs，并且我有以下配置。当我应用模板时，只会创建一个 CronJob。被创建的总是第二个。所以看起来第一个被第二个覆盖了。我无法弄清楚我做错了什么。

kubectl apply -f multicron.yaml
cronjob.batch/my-app-addl created

(期望：创建两个CronJob。实际：只创建了一个，也就是第二个)

kubectl get cronjob -n commercial
NAME            SCHEDULE        SUSPEND   ACTIVE   LAST SCHEDULE   AGE
my-app-addl     15/30 * * * *   False     0        <none>          9s

我可以通过在 CronJob 条目之间使用 --- 分隔文档来解决这个问题
