Official Docs https://docs.celo.org/network/mainnet/run-full-node#running-an-archive-node

Pre-requisites

Update, upgrade, and clean the system, and then firewall management (ufw), Docker, and the Git version control system.

sudo apt update -y && sudo apt upgrade -y && sudo apt auto-remove -y
sudo apt install docker.io docker-compose git ufw -y

Set explicit default UFW rules

sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow SSH, HTTP and HTTPS

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

Get the IP address of the host machine, you can use the following command in a terminal or command prompt

curl ifconfig.me

Set an A record for a domain, you need to access the domain's DNS settings and create an A record that points to the IP address of the host machine. This configuration allows users to reach your domain by resolving the domain name to the specific IP address associated with your host machine.

Create Celo directory

The first command, mkdir celo, will create a new directory named celo in the current location. The second command, cd celo, will change your current working directory to the newly created celo directory. Now you are inside the celo directory and can start storing docker-compose and related files in it.

mkdir celo
cd celo

Create .env file

sudo nano .env

Paste the following into the file.

EMAIL={YOUR_EMAIL} #Your email to receive SSL renewal emails
DOMAIN={YOUR_DOMAIN} #Domain of your reth node you set earlier, reth.indexerdao.com
WHITELIST={YOUR_REMOTE_MACHINE_IP} # Remote IP's allowed to connect to RPC

Run Celo Node

docker-compose up -d

Monitor Logs

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

docker logs celo -f

Test Celo RPC 🧪

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

You should receive a result. i.e.

{"jsonrpc":"2.0","id":1,"result":{"batchProcessed":308668,"batchSeen":308668,"blockNum":96352870,"broadcasterQueuedMessagesPos":0,"lastL1BlockNum":17885784,"lastl1BlockHash":"0x758b86452273e12b74cdfdc1fb11c373e25589676c09b9b42fd917015fcdeccd","messageOfLastBlock":74145055,"messageOfProcessedBatch":97883962,"msgCount":97884349}}
