Quickly deploy an Ethereum node for RPC provision, using docker for easy setup and management, Nethermind and Nimbus clients.

Ethereum node is an instance that contains a full copy of the blockchains transaction history and state, this is connected to other nodes on the network for security and decentralisation.

This guide is without a validator client (for staking), and exposing the node externally to be used as an endpoint for connecting to the Ethereum blockchain.

Nimbus: is a super light-weight client to save on space and resources.

Node may take a few days to sync depending on Hardware, its recommended to have 2TB of storage (SSD or NVMe).

Install Docker

Update system, then install docker and docker compose plugin

sudo apt update && sudo apt upgrade -y
sudo apt install curl -y

curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh

sudo rm -r get-docker.sh
sudo usermod -aG docker $USER

check installed with

docker --version
docker compose version

Make working directory

mkdir -p /home/$USER/eth-node/el-client
mkdir /home/$USER/eth-node/cl-client

JWT authentication token, to allow EL-client to communicate with CL-client

mkdir /home/$USER/eth-node/jwtsecret

openssl rand -hex 32 | tr -d "\n" > "/home/$USER/eth-node/jwtsecret/jwtsecret.hex"

cd eth-node
nano docker-compose.yml

Paste the following docker-compose configuration

Replace <YOUR_EXTERNAL_IP> with public IP address

open in firewall settings

sudo ufw allow 8545     # rpc port 
sudo ufw allow 9000     # cl-p2p
sudo ufw allow 30303    # el-p2p

Port forward these ports also from your router settings.

This should allow connection the node as an RPC endpoint, with http:<public-ip-address-of-node>:8545

If connecting to this node from the same device, http:localhost:8545

sudo docker compose up -d

check logs

sudo docker compose logs -f execution
sudo docker compose logs -f consensus

Execution- nethermind

Consensus

Check running containers

sudo docker ps -a

Stop/Restart node

sudo docker stop <container-name> && sudo docker rm <container-name>
sudo docker start <container-name>

with docker compose, from working directory

sudo docker compose down
sudo docker compose up -d
