CKA study material · question 520 of 1000

An operator starts a container directly through the container runtime on a node, outside Kubernetes. How does the scheduler account for the resources it consumes?

  1. It subtracts them from the node's allocatable capacity automatically
  2. It counts them once the kubelet next reports node status
  3. It does not count them at all
  4. It refuses to schedule to that node until the container is removed
Show the answer

Answer: C. It does not count them at all

The scheduler sums the requests of containers the kubelet manages, and explicitly excludes containers the runtime was told to start directly and processes outside the kubelet's control. Reserving for those needs system-reserved settings.
