Starting with embedded cluster version 1.15.0, bind mounts are no longer needed or recommended and the data directory can be configured using the --data-dir flag to the install command. For more information see Change the Default Data Directory in the docs. The data directory cannot be relocated after installation.
Additionally, the k0s and openebs data directories have been consolidated under /var/lib/embedded-cluster in the directories /var/lib/embedded-cluster/k0s and /var/lib/embedded-cluster/openebs-local respectively.
