Kubernetes kubelets can be run with a specific set of options (https://kubernetes.io/docs/admin/kubelet/). Is there a way to see, through kubectl or similar way, the options that kubelet was run with?
I basically want to know if --allow-privileged was passed in, but see no way of checking that.
Use ps x | grep kubelet or cat /proc/$(pidof kubelet)/cmdline to get commandline.
If kubelet is installed by apt or yum, mostly it's working as a systemd service.
Take a look at files in /etc/systemd/system/kubelet.service.d/ folder, where the arguments kubelet running with.
