- Ensure the directory is created with 0700 via a new function called CreateDataDirectory(). - Call this function in the init phases instead of the manual call to MkdirAll. - Call this function when joining control-plane nodes with local etcd. If the directory creation is left to the kubelet via the static Pod hostPath mounts, it will end up with 0755 which is not desired.
