# Run a Full Orbit Node

> Learn how to run an Arbitrum Orbit node on your local machine

This guide provides step-by-step instructions for running a Arbitrum Orbit node on your local machine. You can also use this as a basis for running nodes of arbitrary orbit rollups on Gelato.

## Prerequisites

Before you begin, ensure you have the latest Docker image as mentioned in the Arbitrum Docs:

<Card title="Run Full Node" icon="link" href="https://docs.arbitrum.io/run-arbitrum-node/run-full-node">
  Arbitrum
</Card>

Get the `chain-info.json` from the dashboard by heading over to [https://app.gelato.cloud/chains](https://app.gelato.cloud/chains) and then downloading the "Genesis File" from the "Details" tab.

## Minimum Hardware Requirements

{(() => {
const hardwareRequirements = [
  { component: "CPU", requirement: "2-4 core CPU (For AWS: t3 xLarge)" },
  { component: "RAM", requirement: "8-16 GB" },
  { component: "Disk", requirement: "Depends on traffic volume" }
];

return (

      {hardwareRequirements.map((item, idx) => (

## Shutting Down the Node

<Info>
  To ensure the current state is saved properly, allow a graceful shutdown:

```bash theme={null}
docker stop --time=300 $(docker ps -aq)
