| # Clawsiecats | ||
|
|
||
| A configuration optimized for limited compute availability, supposed to be deployed on VPS machines. | ||
| It hosts routing services, tailscale, some other useful stuff. It has impermanence enabled. | ||
|
|
||
| Uncomment the disko partioning configuration that should be used in [flake.nix](/flake.nix) under the | ||
| variant before deployment. Supports MBR, GPT, GPT+LUKS. I haven't gotten MBR+LUKS working yet. | ||
|
|
||
|
|
||
| ## Vultr (GPT, GPT+LUKS) | ||
|
|
||
| The configuration looks to work fine on the most minimal [Vultr](https://www.vultr.com/) configuration. | ||
|
|
||
| | CPU | Memory | Disk Space | | ||
| |-------|----------|------------| | ||
| | 1 vCPU | 0.5 GB | 10 GB SSD | | ||
|
|
||
| **Deployment Steps** | ||
|
|
||
| 1. Replace your SSH public keys in [/generators/minimal.nix](/generators/minimal.nix). | ||
|
|
||
| 2. Build the minimal ISO: | ||
| ```bash | ||
| $ nix build '.#minimal-iso' | ||
| $ ls ./result/iso/nixos.iso | ||
| ``` | ||
|
|
||
| 3. Deploy a new machine on Vultr (any OS). | ||
|
|
||
| 4. Update the machine settings on Vultr to boot from the generated ISO. | ||
| Vultr takes in the ISO URL, so I'll need to host this ISO somewhere first. | ||
|
|
||
| 5. Replace the SSH public keys in [/machines/clawsiecats/minimal.nix](/machines/clawsiecats/minimal.nix). | ||
|
|
||
| 6. Deploy the configuration using nixos-anywhere: | ||
| ```bash | ||
| # For GPT+LUKS | ||
| $ ./machines/clawsiecats/anywhere.sh '.#clawsiecats-luks' root@vps.machine.ip.address --luks | ||
|
|
||
| # For GPT | ||
| $ ./machines/clawsiecats/anywhere.sh '.#clawsiecats' root@vps.machine.ip.address | ||
| ``` | ||
| The installation succeeds hopefully. | ||
|
|
||
| 7. Remove the ISO from Vultr machine settings and let the machine reboot. | ||
|
|
||
| 8. (GPT+LUKS only) Decrypt the drive in dropbear: | ||
| ``` | ||
| $ ssh vps.machine.ip.address -p 2222 | ||
| ``` | ||
|
|
||
| 9. Log in to the freshy installed NixOS: | ||
| ``` | ||
| $ ssh vps.machine.ip.address | ||
| ``` | ||
|
|
||
|
|
||
| ## HostVDS (MBR) | ||
|
|
||
| The configuration goes tortoise after a while on the most minimal [HostVDS](https://hostvds.com/) configuration. | ||
|
|
||
| | CPU | Memory | Disk Space | | ||
| |-------|----------|------------| | ||
| | 1 vCPU | 1.0 GB | 10 GB SSD | | ||
|
|
||
| This, however, seems like HostVDS issue to me more than configuration overloading the machine. | ||
|
|
||
| The very next tier machine looks to work fine. | ||
|
|
||
| | CPU | Memory | Disk Space | | ||
| |-------|----------|------------| | ||
| | 1 vCPU | 2.0 GB | 20 GB SSD | | ||
|
|
||
| **Deployment Steps** | ||
|
|
||
| 1. Replace your SSH public keys in [/generators/minimal.nix](/generators/minimal.nix). | ||
|
|
||
| 2. Create a new instance on HostVDS and choose Debian 12 as the OS. | ||
|
|
||
| 3. Deploy the configuration using nixos-anywhere: | ||
| ```bash | ||
| $ ./machines/clawsiecats/anywhere.sh '.#clawsiecats' root@vps.machine.ip.address | ||
| ``` | ||
| The installation succeeds hopefully. | ||
|
|
||
| 4. Let the machine reboot. | ||
|
|
||
| 5. Log in to the freshy installed NixOS: | ||
| ``` | ||
| $ ssh vps.machine.ip.address | ||
| ``` | ||
|
|
||
|
|
||
| ## Minimal configuration (for testing purpose): | ||
|
|
||
| ```bash | ||
| $ ./machines/clawsiecats/anywhere.sh '.#clawsiecats-minimal' root@vps.machine.ip.address | ||
| ``` |

| - Update machine specific values in `environment.nix`. | ||
| - Setup Intel/AMD/Nvidia graphics in `graphics.nix`. If I want to use Intel graphics, then comment out | ||
| `graphics.nix` entirely. If I want to be using Nvidia graphics, then leave `graphics.nix` unmodified. | ||
| - Rebuild config: | ||
| ```sh | ||
| # Create a machine specific `hardware-configuration.nix`. | ||
| $ sudo nixos-generate-config | ||
|
|
||
| $ cd /etc/nixos/ | ||
| $ nix flake update | ||
|
|
||
| $ sudo nixos-rebuild boot --flake '.#mishy' | ||
| $ sudo shutdown -r now | ||
