Access to files outside of pod saved by longhorn.

Hey. I have a cluster with some nodes and longhorn configured.
How can I edit files e.g. wordpress that I pull with volumeMount outside of poda (e.g. index.html). Previously I was using NFS and just went to the network share and made changes there. When I use longhorn I can’t edit files that way, due to the fact that it is block storage. I thought of creating an NFS/SMB server on kubernetes that would have access to the same PVCs as longhorn and then I could make changes as I did before. However, the problem arises when I have multiple wordpress sites in several other namespaces. Then I would have to create a separate NFS/SMB server for the namespace, which is not good.
