CKA study material · question 608 of 1000

A static Pod manifest on a node references a ConfigMap, and the value never arrives. Why?

  1. The kubelet reads static Pod manifests before the API server is available
  2. Static Pods cannot use ConfigMaps or Secrets at all
  3. The mirror Pod hides the volume from kubectl but the data is present
  4. Static Pods may only use ConfigMaps in the kube-system namespace
Show the answer

Answer: B. Static Pods cannot use ConfigMaps or Secrets at all

Nothing fetches API objects on a static Pod's behalf, so ConfigMaps and Secrets are unavailable to them and the configuration has to arrive another way, such as a host path.
