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:

Run Full Node

Arbitrum

Get the chain-info.json from the dashboard by heading over to https://raas.gelato.network/chains and then downloading the “Genesis File” from the “Details” tab.

​
Minimum Hardware Requirements

ComponentMinimum Requirement
CPU2-4 core CPU (For AWS: t3 xLarge)
RAM8-16 GB
DiskDepends on traffic volume
1

Create a directory for the chain

mkdir -p ~/orbit-node
2

Run the node

docker run --rm -it  -v ~/orbit-node:/home/user/.arbitrum \

Check the node status

curl -X POST http://localhost:8547/ \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

​
Shutting Down the Node

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

docker stop --time=300 $(docker ps -aq)
