# Midgard - Docker

{% hint style="info" %}
The steps shown here are tested on `Ubuntu 24.04`, different distributions may need adjustments to the commands.

All commands are meant to be run as root user, if not specified otherwise. Depending on the server installation, they may need to be run from a different user via `sudo`.
{% endhint %}

## Prerequisites

Install all packages needed for running and configuring the Midgard container

```sh
apt install -y --no-install-recommends docker.io
```

## Configuration

### Work directories

Prepare work directories

```sh
mkdir -p /opt/timescale
mkdir -p /opt/midgard/{config,blockstore}
```

### Genesis

Download the genesis file.

{% hint style="warning" %}
Nine Realms infrastructure has been decommissioned. Refer to the upstream [node-launcher documentation](https://gitlab.com/thorchain/devops/node-launcher/-/tree/master/docs) for the current genesis file source.
