Run a non-validator node

Overview

This guide demonstrates how to run a non-validator node on the mainnet using Docker. A non-validator node is also known as an RPC (remote procedure call) node.

Before you start

Docker

System requirements

Recommended system requirements for running a non-validator node on the mainnet:

6-core CPU
25 GB RAM
700 GB high-speed SSD
x86-64 architecture

These hardware requirements are rough guidelines, and each node operator should monitor their node to ensure good performance for the intended task. The size of your node will also grow over time.

Run the node

Set up directories:

Create a node directory:
```
mkdir ~/ronin
```
Go to the newly created directory:
```
cd ~/ronin
```
Create a chain data directory:
```
mkdir -p chaindata/data/ronin
```
Create a file called docker-compose.yml:
```
vim docker-compose.yml
```

Paste the following into docker-compose.yml:

version: "3"
services:
  node:
    image: ${NODE_IMAGE}
    stop_grace_period: 5m
    stop_signal: SIGINT
    hostname: node
    container_name: node
    ports:
      - 127.0.0.1:8545:8545
      - 127.0.0.1:8546:8546
      - 30303:30303
      - 30303:30303/udp
      - 6060:6060
    volumes:
      - ~/ronin/chaindata:/ronin
    environment:
      - SYNC_MODE=full
      - PASSWORD=${PASSWORD}
      - NETWORK_ID=${NETWORK_ID}
      - RONIN_PARAMS=${RONIN_PARAMS}
      - VERBOSITY=${VERBOSITY}
      - MINE=${MINE}
      - GASPRICE=${GASPRICE}
      - ETHSTATS_ENDPOINT=${INSTANCE_NAME}:${CHAIN_STATS_WS_SECRET}@${CHAIN_STATS_WS_SERVER}:443

This compose file defines the node service, which pulls a Ronin node image from the GitHub Container Registry.

Create an .env file to store configuration parameters for the service:
```
vim .env
```

Paste the following into .env and replace placeholder values (like INSTANCE_NAME) with your node's information:

# The name of your node that you want displayed on https://ronin-stats.roninchain.com/
INSTANCE_NAME=INSTANCE_NAME

# The latest version of the node's image as listed in https://docs.roninchain.com/validators/setup/upgrade-validator
NODE_IMAGE=NODE_IMAGE

# The password used to encrypt the node's private key file
PASSWORD=PASSWORD

MINE=false

NETWORK_ID=2020
GASPRICE=20000000000
VERBOSITY=3

CHAIN_STATS_WS_SECRET=WSyDMrhRBe111
CHAIN_STATS_WS_SERVER=ronin-stats-ws.roninchain.com

RONIN_PARAMS=--http.api eth,net,web3,consortium --txpool.pricelimit 20000000000 --txpool.nolocals --discovery.dns enrtree://AIGOFYDZH6BGVVALVJLRPHSOYJ434MPFVVQFXJDXHW5ZYORPTGKUI@nodes.roninchain.com

(Optional) Download the snapshot from the ronin-snapshot repo:

cd ~/ronin/chaindata/data/ronin/
wget -q -O - <snapshot URL from the README file in the repo> | tar -I zstd -xvf -

Start the node:
```
cd ~/ronin && docker-compose up -d
```
This command pulls a Ronin node image and starts the service you defined.
Review the log:
```
docker logs node -f --tail 100
```
After a few minutes, check the status of your node on the Ronin Network Status page. If it's green, the node is connected and up to date with the network.
