Misdeleted the heartbeat cronjob

[ywtung]

I was trying to disable the heartbeat by editing the ConfigMap of Linkerd but after I finished it the heartbeat seems not to be disabled, after that I misdeleted the heartbeat cronjob, is there any way to recover the cronjob? Or is it effected to the whole Linkerd system?

Environment: EKS
Version: Stable 2.11.1
Kubernetes Version: 1.22.4

I would greatly appreciate it if who knows the answer and helps.

You can just perform a linkerd upgrade, even if it's to the same version you already have installed. Either through the CLI or Helm. That should reestablish the erased CronJob.
