Autofs: mounting the Hetzner Storage Box automatically

Requirements

Besides having a Linux server and a Hetzner Storage Box, you will need to set up SSH keys for the storage box.

This tutorial is based on Debian/Ubuntu. It works the same on SUSE or RedHat based distros, though the package names could differ.

Install packages

sudo apt install fuse3 sshfs autofs

Prepare folders

sudo /mnt/hetzner/

Setup ssh key to box storage

cat ~/.ssh/id_ed25519.pub | ssh -p23 [email protected] install-ssh-key

Setup autofs

sudo nano /etc/auto.master

Adding this:

/mnt/hetzner /etc/auto.hetzner --timeout=60 --ghost

sudo nano /etc/auto.hetzner

Adding this and adapt:

backup-storage -fstype=fuse,rw,allow_other,IdentityFile=/root/.ssh/hetzner_backup,StrictHostKeyChecking=no,ServerAliveInterval=15,ServerAliveCountMax=3,reconnect,uid=0,gid=0,umask=022 :sshfs\#[email protected]\:/

Stating and enabling autofs

sudo systemctl enable autofs
sudo systemctl start autofs
sudo systemctl status autofs
sudo systemctl restart autofs

Testing

sudo ls -lah /mnt/hetzner
mkdir -p /mnt/hetzner/backup-storage/test
sudo ls -lah /mnt/hetzner/backup-storage/
