DCA Question #90: Real Exam Question with Answer & Explanation

Question

You want to provide a configuration file to a container at runtime. Does this set of Kubernetes tools and steps accomplish this? Solution: Turn the configuration file into a configMap object and mount it directly into the appropriate pod and container using the .spec.containers.configMounts key.

Options

• AYes
• BNo

Explanation

While using a ConfigMap is the correct approach to provide configuration files, the .spec.containers.configMounts key is an incorrect and non-existent method for mounting them into a container.

Common mistakes.

• A. The method for mounting ConfigMaps into containers is via volumes and volume mounts (.spec.volumes and .spec.containers.volumeMounts), not through a non-existent key like .spec.containers.configMounts.
