Planning

To-do

• Copy over ~/.ssh/id_ed25519 and zellij status bar plugin confirmation
• Migrate immich to apollo, point to helios
• Migrate LibreChat to apollo, maintain db
• Figure out wakapi
• Add forgejo
• Add simple blog

Versions

• 1.0.0
  • Setup desktop as hypervisor with nixos and win11
    • Spare drive as steam library
    • GPU passthrough to either system
    • Always running, VMs spun down except when in use
  • Apollo as hypervisor
    • VMs for docker host, home-assistant, bare metal or containerised services
  • Automated backups for home and state directories
  • Ability to build VMs of all systems and implement integration tests
    • Staging VMs for ad-hoc testing
  • All servers set up with following services:
    • Git server
    • Chat app
    • Network shares
    • Federation with ActivityPub
    • Wakapi
  • Add a way to define services per host and refer to them by hostname
  • helios as file and db server, apollo as services and reverse proxy
• 0.3.0
  • Integration tests for all services
  • Migrate services from helios

Modules

The nixosModules and homeModules exposed by this flake are slightly out of the norm.

Option declarations for user specific configuration are kept to:

• homeModules for CLI
• nixosModules for desktop

System configurations, to this end, should include the window manager, lockscreen, terminal etc. for that system.

These desktop programs will be configured in home-manager for each user, but those configurations consult the osConfig variable passed in by home-manager.

System Setup

The following files are required for system activation:

• /persist/home/${mainUser}/.ssh/id_ed25519

This private key will be used by sops-nix to decrypt the secrets in this encrypted file. The secrets inside the yaml file should also be set, or otherwise removed alongside their declarations , found here and references.

# On the target machine
# Boot into the NixOS installer

sudo passwd

# On the host machine
deploy --user "rafiq" --ip "10.10.0.102" --hostname "apollo"

From a Local NixOS Installer

The installation may run out of space when installing from an install ISO. In that case, use Disko to format the drives first, then create a /mnt/tmp directory and set it as TMPDIR for nixos-install.

sudo su
nix --extra-experimental-features "nix-command flakes" run github:nix-community/disko/master -- --mode destroy,format,mount --flake github:rrvsh/pantheon#<HOSTNAME>
# Copy SSH key to /persist/home/rafiq/.ssh
mkdir /mnt/tmp
TMPDIR=/mnt/tmp nixos-install --flake github:rrvsh/pantheon#<HOSTNAME> --no-root-password
reboot

Impermanence

System and user state is stored under /persist. Anything not declared under {environment,home}.persistence is deleted on system boot.
