如何使用 kubectl 查看 CronJob 的 restartPolicy？

Question

有没有办法查看使用 kubectl 的 CronJob 的 restartPolicy？

这是我的 Kubernetes 版本信息：

Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.4", GitCommit:"d360454c9bcd1634cf4cc52d1867af5491dc9c5f", GitTreeState:"clean", BuildDate:"2020-11-12T01:09:16Z", GoVersion:"go1.15.4", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"18+", GitVersion:"v1.18.9-eks-d1db3c", GitCommit:"d1db3c46e55f95d6a7d3e5578689371318f95ff9", GitTreeState:"clean", BuildDate:"2020-10-20T22:18:07Z", GoVersion:"go1.13.15", Compiler:"gc", Platform:"linux/amd64"}

这就是我在运行 kubectl describe cronjob -n default example-job:

时看到的

你为什么不试试这样的东西 -

kubectl -n {namespace-name-here} get cronjob

这将为您提供该命名空间中的所有 cronjobs

kubectl -n {namespace-name-here} get cronjob {cronjob-name} -o yaml

这将显示用于创建 cronjob 的 yaml
