Error: unknown flag: --blocking-pod-selector

[yosbeleg89]

I have configured a Flag: --blocking-pod-selector=runtime=long to prevent kured to reboot some pods when running (according to the documentation), now Kured pods are in a CrashLoopBackOff status and the logs are:

Error: unknown flag: --blocking-pod-selector
Usage:
  kured [flags]

Flags:
      --alert-filter-regexp regexp.Regexp   alert names to ignore when checking for active alerts
      --ds-name string                      name of daemonset on which to place lock (default "kured")
      --ds-namespace string                 namespace containing daemonset on which to place lock (default "kube-system")
  -h, --help                                help for kured
      --lock-annotation string              annotation in which to record locking node (default "weave.works/kured-node-lock")
      --period duration                     reboot check period (default 1h0m0s)
      --prometheus-url string               Prometheus instance to probe for active alerts
      --reboot-sentinel string              path to file whose existence signals need to reboot (default "/var/run/reboot-required")

time="2019-03-07T16:57:24Z" level=fatal msg="unknown flag: --blocking-pod-selector"

Which shows like the flag isn't supported. I'm using version 1.1.0 of kured.

If you check out the source and compare the 1.1.0 tag to master you will notice that the selector isn't supported. To be able to use that flag you will need to build source and create your own container image. I just hit the same problem in my setup and stumbled on your issue trying to troubleshoot. Hope this helps!

Thanks @tbauers for let me know that. I will go with that option if there is no plan to release soon an oficial updated release of kured.

@awh is there an estimated date for a next official release of kured? Thanks
