Install RancherOS on Hetzner (or from initramfs other than RancherOS)

Notes

You may want to use the following aliases for SSH

ssh-nocare-hostkey (try public keys (RancherOS rejects after too many keypair attempts))

ssh \
  -o PubkeyAuthentication=yes \
  -o UserKnownHostsFile=/dev/null \
  -o StrictHostKeyChecking=no

ssh-nocare (do not use public key (when hetzner is in recovery/pxe-boot))

ssh \
  -o PubkeyAuthentication=no \
  -o UserKnownHostsFile=/dev/null \
  -o StrictHostKeyChecking=no

run the line below

curl https://raw.githubusercontent.com/hkeio/boot-rancheros-hetzner/master/run.sh > rancher.sh && chmod +x rancher.sh && ./rancher.sh

install rancher os http://docs.rancher.com/os/running-rancheros/server/install-to-disk/

after rebbot login with displayed credentials and run

sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server
