Run a testnet node

This guide demonstrates how to run an RPC node (non-validator node) on the Saigon testnet using Docker.

Prerequisites

Install Docker Engine and the Docker Compose plugin:

Steps

Set up directories:

mkdir -p ~/ronin/docker
cd ~/ronin

Create a directory for chain data:

mkdir -p chaindata/data/ronin

In the docker directory, create a docker-compose.yml file with the following configuration:

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=${GASPRICE}
      - GENESIS_PATH=${GENESIS_PATH}
      - ETHSTATS_ENDPOINT=${INSTANCE_NAME}:${CHAIN_STATS_WS_SECRET}@${CHAIN_STATS_WS_SERVER}:443

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

In the docker directory, create an .env file and add the following content, replacing the <...> placeholder values with your 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=2021
GASPRICE=20000000000
VERBOSITY=3

CHAIN_STATS_WS_SECRET=xQj2MZPaN72
CHAIN_STATS_WS_SERVER=ronin-stats-ws.roninchain.com

CONFIG_PATH=config.testnet.json
GENESIS_PATH=testnet.json
DEPLOYMENT=test

RONIN_PARAMS=--http.api eth,net,web3 --txpool.pricelimit 20000000000 --txpool.nolocals --discovery.dns enrtree://AJCNIAXQIPO55NW3QE2NUBBDMPYZDOQUCAEUS65NHQFMUUFES5KOW@saigon.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 && 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 Analytics page, the Testnet section. If it's green, the node is connected and up to date with the network.
