This is a post about mounting a ssh drive and a test post first i have published in a couple of years with the new WP. Also sshfs is now sadly unmaintained
Login to the share1 VM and create a folder to share and set the permissions to share it. We already have the user c0mputerking king created on the share1 VM and the webhost so fairly easy harder if you have to create a user as well with matching UID and GID should probably add that here too.
mkdir -p /zones/dataset-share1/fileshare/c0mputerking
chown c0mputerking:c0mputerking /zones/dataset-share1/fileshare/c0mputerking
Next login to the webhost to test with this command
sshfs email@example.com:/zones/dataset-share1/fileshare/c0mputerking /mnt/zones/dataset-share1/fileshare/c0mputerking
Generate some credentials on the client which is the webhost machine and the user you will be using c0mputerking in this case. Next copy the credentials to the share1 VM you need this to you can add a line to fstab on the client for mounting at boot time.
c0mputerking@webhost$ ssh-copy-id firstname.lastname@example.org
Add this to fstab on webhost
email@example.com:/zones/dataset-share1/fileshare/c0mputerking /mnt/zonesf/fileshare/c0mputerking fuse.sshfs allow_other,reconnect,IdentityFile=/home/c0mputerking/.ssh/id_rsa 0 0
