Installing a playground VM
I've used gnome-boxes from my current Fedora laptop for running playground vm's.
Settings: ISO: nixos-minimal Hard drive: 32GB RAM: 2GB EFI: Enable
Expose port 22 to allow ssh into vm (host port 3022, guest 22)
# set temp root passwd
sudo su
passwd
sshd is already running, so you can now ssh into the vm remotely for the rest of the setup.
ssh root@127.0.0.1 -p 3022
# Partitioning
parted /dev/sda -- mklabel gpt
parted /dev/sda -- mkpart root ext4 512MB -8GB
parted /dev/sda -- mkpart swap linux-swap -8GB 100%
parted /dev/sda -- mkpart ESP fat32 1MB 512MB
parted /dev/sda -- set 3 esp on
# Formatting
mkfs.ext4 -L nixos /dev/sda1
mkswap -L swap /dev/sda2
mkfs.fat -F 32 -n boot /dev/sda3
# Mounting disks for installation
mount /dev/disk/by-label/nixos /mnt
mkdir -p /mnt/boot
mount /dev/disk/by-label/boot /mnt/boot
swapon /dev/sda2
# Generating default configuration
nixos-generate-config --root /mnt
From this config copy the bootstrap configuration and fetch the hardware configuration.
scp -P 3022 nixos/hosts/bootstrap/configuration.nix root@127.0.0.1:/mnt/etc/nixos/configuration.nix
scp -P 3022 root@127.0.0.1:/mnt/etc/nixos/hardware-configuration.nix nixos/hosts/nixosvm/hardware-configuration.nix
Then back to the VM
nixos-install
reboot
nixos-rebuild switch
Set the password for the user that was created.
passwd truxnell
Also grab the ssh keys and re-encrypt sops
Login as user, copy nix git
mkdir .local
cd .local
git clone https://github.com/szinn/nix-config.git
cd nix-config
Apply config to bootstrapped device
First time around, MUST APPLY with name of host in ./hosts/
This is because .. --flake . looks for a nixosConfigurations key with the machines hostname
The bootstrap machine will be called 'nixos-bootstrap' so the flake by default would resolve nixosConfigurations.nixos-bootstrap
Subsequent rebuilds can be called with the default command as after first build the machines hostname will be changed to the desired machine
nixos-rebuild switch --flake .#<machinename>
