k8s-on-raspbian: Failed to find subsystem mount for required subsystem: pids

Expected Behaviour

kubernetes master node starts and kubectl get pods shows Ready status.

Current Behaviour

kubernetes master node starts, and kubectl get pods shows NotReady status

kubectl describe nodes shows this error in the event log: Failed to update Node Allocatable Limits [“kubepods”]: failed to set supported cgroup subsystems for cgroup [kubepods]: Failed to find subsystem mount for required subsystem: pids

Possible Solution

not sure - disable whatever requires this cgroup? is it something new in 1.14? or enable that cgroup in rasberian lite somewhere? (I’m not cgroup expert, so I don’t know how to even start)

Steps to Reproduce (for bugs)

(follow the guide in this repo, I get these results at the “Check everything worked:” step of the guide)

Context

Can’t schedule pods / nodes not ready.
