## Introduction
|
||
|
|
|
||
|
|
__NixOS MicroVM__ refers to a minimalistic virtual machine environment based on the NixOS Linux distribution.
|
||
|
|
The NixOS MicroVM leverages these principles to create a highly customizable and reproducible virtual machine environment. It allows users to define the entire system configuration, including packages, services, and dependencies, in a declarative manner using the Nix language. This ensures that the MicroVM is consistent, easily reproducible, and can be version-controlled.
|
||
|
|
|
||
|
|
In this guide, will learn how to make reproducible, declarative and reliable systems by deploying a NixOS MicroVM weblet in ThreeFold Dashboard.
|
||
|
|
|
||
|
|
For more information on Nix, you can read the [Nix Reference Manual](https://nixos.org/manual/nix/stable/).

## Access the ThreeFold Dashboard
|
||
|
|
|
||
|
|
* Go to the ThreeFold Dashboard website, based on the deployment network you prefer:
|
||
|
|
* [Mainnet](https://dashboard.grid.tf)
|
||
|
|
* [Testnet](https://dashboard.test.grid.tf)
|
||
|
|
* [Devnet](https://dashboard.dev.grid.tf)
|
||
|
|
* [QAnet](https://dashboard.qa.grid.tf)
|
||
|
|
|
||
|
|
* Make sure you have a [wallet](../wallet_connector.md)
|
||
|
|
* From the sidebar click on **Solutions**
|
||
|
|
* Click on **Micro Virtual Machine** to start your NixOS MicroVM Deployment

## Deploy a NixOS MicroVM
|
||
|
|
|
||
|
|
We now present the main steps to properly configure your NixOS MicroVM running on the TFGrid.
|
||
|
|
|
||
|
|
* In the section `Config`, make sure to select `Nixos` as the `VM Image`. You can choose different parameters (CPU, Memory, etc.) for your deployment depending on your workload needs.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
* In the section `Environment Variables`, you can add the default configurations for Nix. Here's an example:
|
||
|
|
* ```
|
||
|
|
{ pkgs ? import <nixpkgs> { } }:
|
||
|
|
let pythonEnv = pkgs.python3.withPackages(ps: [ ]); in pkgs.mkShell { packages = [ pythonEnv ]; }
|
||
|
|
```
|
||
|
|
* This will be written to `/root/default.nix`. You can change the Nix shell configuration there.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
* In the section `Disks`, you should mount a disk large enough for Nix to store its files used for `nix-store`.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
* Once your configured the parameters, you can deploy the MicroVM.
|
||
|
|
|
||
|
|
If you need more information on how to SSH into your deployment, read [this section](../../system_administrators/getstarted/tfgrid3_getstarted.md) of the TF Manual.

## Questions and Feedback
|
||
|
|
|
||
|
|
You should now be able to easily deploy a NixOS MicroVM on the ThreeFold Grid.
