## 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)
|
|
|
|
```sh
|
|
# 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`
|
|
|
|
```sh
|
|
# 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.
|
|
|
|
```sh
|
|
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
|
|
|
|
```sh
|
|
nixos-install
|
|
reboot
|
|
nixos-rebuild switch
|
|
```
|
|
|
|
Set the password for the user that was created.
|
|
|
|
```sh
|
|
passwd truxnell
|
|
```
|
|
|
|
Also grab the ssh keys and re-encrypt sops
|
|
|
|
Login as user, copy nix git
|
|
|
|
```sh
|
|
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 <machinename> 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
|
|
|
|
```sh
|
|
nixos-rebuild switch --flake .#<machinename>
|
|
```
