Deployment commands:
$ ./inv deploy
If you want to reboot a machine, use the following command to also deploy secrets afterwards:
$ inv deploy --hosts build02 reboot --hosts build02
Install/Fix system from Hetzner recovery mode
- Copy your ssh key to the recovery system so that the kexec image can re-use it.
yourmachine> ssh-copy-id root@build0X.nix-community.org
- Download and boot into kexec-image:
$ curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-kexec-installer-x86_64-linux.tar.gz | tar -xzf- -C /root
$ /root/kexec/run
- Format and/or mount all filesystems to /mnt:
$ inv format-disks --hosts buildXX --disks /dev/nvme0n1,/dev/nvme1n1
- Setup secrets
$ inv setup-secret --hosts buildXX
- Generate configuration and download to the repo
$ nixos-generate-config --root /tmp
# optional, in most cases one can import roles/hetzner/amd.nix
$ scp buildXX.nix-community.org:/tmp/etc/nixos/hardware-configuration.nix buildXX/hardware-configuration.nix
- Build and install
$ inv install-nixos --hosts buildXX
Debug VM
You can start a vm from the rescue system in order to debug the boot:
$ nix-shell -p qemu_kvm --run 'qemu-kvm -m 10G -hda /dev/sda -hdb /dev/sdb -curses -cpu host -enable-kvm'
