Docker Exam DCA Topic 3 Question 79 Discussion

This strategy does not successfully mount the /data directory on your laptop into a container. Setting containers.mounts.hostBinding to /data in the container's specification is not a valid way to mount a host directory into a container in Kubernetes. Kubernetes does not support mounting arbitrary host directories into containers, as this would break the portability and isolation of pods across different nodes. To mount a host directory into a container in Kubernetes, you need to use one of the following methods:

Use hostPath volume, which allows you to mount a file or directory from the host node's filesystem into your pod.

Use local volume, which allows you to mount local storage devices such as disks or partitions into your pod.

Use persistentVolume and persistentVolumeClaim with hostPath or local volume as storage class, which allows you to abstract the details of how storage is provided from how it is consumed.
