sudo ufw allow 22/tcp
sudo ufw allow 80
sudo ufw allow 443

Setup

Clone the boba_legacy repository to get started

git clone [email protected]:bobanetwork/boba_legacy.git
cd boba_community/boba_node

Setting up Environment Variable

You can locate environment files at boba_legacy/ops/envs/ folder.

Start The Node

docker-compose -f [docker-compose-file] up -d

Monitor Logs

Use docker logs to monitor your boba node. The -f flag ensures you are following the log output

docker logs dtl -f
docker logs replica -f

Test RPC:

curl --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}' 
-H "Content-Type: application/json" -X POST https://{DOMAIN}

You should receive a result after the node is synced:

{
	"jsonrpc":"2.0",
	"id":1,
	"result":{HEX_VALUE}
}
