Configmap — Certified Kubernetes App Developer (CKAD) Practice Questions
A ConfigMap is a Kubernetes object that stores non-sensitive configuration data as key-value pairs, allowing application configuration to be separated from container images. The CKAD exam tests creating ConfigMaps imperatively from literal values or files, and consuming them inside pods as environment variables, individual mounted files, or entire directory mounts. Candidates must understand that changes to a mounted ConfigMap are eventually reflected in the pod without a restart, while environment variable sourcing requires a pod restart to pick up updates. ConfigMaps are a core building block for twelve-factor application design in Kubernetes and appear heavily throughout the exam.
