This is an example to use NFS External Storage.

NFS server is required to be running on your LAN, refer to here.
On this example, configure [/home/nfsshare] directory on [nfs.srv.world] as a shared directory.

Podman Host must be an NFS client, refer to here for NFS client settings.
[3] Create a volume for NFS and use it.
# create [nfs-volume] volume

root@dlp:~ # podman volume create \
--opt type=nfs \
--opt o=rw \
--opt device=nfs.srv.world:/home/nfsshare nfs-volume 
nfs-volume
# display volume list

root@dlp:~ #
podman volume ls
