This is because hostPath volumes directly mount directories from the host node's filesystem, and Kubernetes does not modify the file ownership or permissions of the host's file system when doing so. Yes, you heard it right. 1 and SMB). It covers the deployment of the CSI Driver as a DaemonSet, creating new mounts, and accessing existing shares. There are different kinds of volume that you can use for different purposes, such as: populating a configuration file based on a ConfigMap or a Secret providing some temporary scratch space for a pod sharing a filesystem between two different containers in the For this solution, I need something outside Kubernetes that mounts the SMB shares automatically on each Kubernetes node; Is there a better solution that I am missing? The Kubernetes object that seems to match this approach the most closely is the Projected Volume, since it "maps existing volume sources into the same directory". 3 Installation method: kind Host OS: Debian 11 I understand that it is not KNative forum, but I really need help, and I would appreciate if you point me in the right direction. conf file made it so that files I copied to the NAS showed up correctly on both the NAS and the W10 mount.
