# Create host with disko-install # Create host with nixos-anywhere
How to use disko-install is described here: https://github.com/nix-community/disko/blob/master/docs/disko-install.md We use a nixos-anywhere wrapper script to deploy new hosts.
--- The wrapper script takes care of copying persistent host keys before calling nixos-anywhere.
Here are the exact steps to get bakunin running:
First create machines/hostname/configuration.nix To accomplish that boot the host from a nixos image and setup a root password.
Add hosts nixosConfiguration in machines/configurations.nix
Boot nixos installer on the Machine.
``` bash ``` bash
# establish network connection sudo su
wpa_passphrase "network" "password" > wpa.conf passwd
wpa_supplicant -B -i wlp3s0 -c wpa.conf ```
ping 8.8.8.8
# if that works continue
# generate a base hardware config After that get the hosts ip using `ip a` and start deployment from your own machine:
nixos-generate-config --root /tmp/config --no-filesystems
# get the infra repo ``` bash
nix-shell -p git # from infrastrucutre repository root dir:
git clone https://git.dynamicdiscord.de/kalipso/infrastructure nix develop .#
cd infrastructure remote-install hostname 10.0.42.23
# add the new generated hardware config (and import in hosts configuration.nix)
cp /tmp/config/etc/nixos/hardware-configuration.nix machines/bakunin/
# check which harddrive we want to install the system on
lsblk #choose harddrive, in this case /dev/sda
# run nixos-install on that harddrive
sudo nix --extra-experimental-features flakes --extra-experimental-features nix-command run 'github:nix-community/disko/latest#disko-install' -- --flake .#bakunin --disk main /dev/sda
# this failed with out of memory
# running again showed: no disk left on device
# it seems the usb stick i used for flashing is way to small
# it is only
# with a bigger one (more than 8 gig i guess) it should work
# instead the disko-install tool i try the old method - first partitioning using disko and then installing the system
# for that i needed to adjust ./machines/modules/disko/btrfs-laptop.nix and set the disk to "/dev/sda"
sudo nix --extra-experimental-features "flakes nix-command" run 'github:nix-community/disko/latest' -- --mode format --flake .#bakunin
# failed with no space left on device.
# problem is lots of data is written to the local /nix/store which is mounted on tmpfs in ram
# it seems that a workaround could be modifying the bootable stick to contain a swap partition to extend tmpfs storage
