Installation

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

# Install Docker Packages including Docker Compose
 sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
 
# Verify Docker Engine Installation
sudo docker run hello-world

Build Ethereum Sepolia Archive Node with Erigon

Create Directory

mkdir -p /root/sepolia && cd /root/sepolia

Create docker-compose.yml

echo "services:
  erigon:
    image: "erigontech/erigon:latest"
    container_name: erigon-sepolia
    ports:
      - "30303:30303"
      - "8545:8545"
      - "9090:9090"
    volumes:
      - erigon_data:/root/erigon/.local/share/erigon
    command:
      - "--chain=sepolia"
      - "--http"
      - "--http.api=net,web3,eth,debug"
      - "--http.corsdomain=*"
      - "--http.addr=0.0.0.0"
      - "--http.port=9545"
      - "--http.vhosts=*"
    restart: unless-stopped
volumes:
  erigon_data:" > docker-compose.yml

Run Ethereum Sepolia Archive Node

 # Run the below code from within /root/sepolia
 docker compose up -d

Using Erigon for Ethereum Sepolia requires the Archive Node to download snapshots. When it is done you can begin querying and interacting with your node. See the next section for information regarding checking sync status.

Interact with Sepolia Archive Node

Check Logs of Erigon Sepolia

Checking Logs will allow you to view sync status.

docker compose logs erigon-sepolia

Stop Archive Node

docker stop erigon-sepolia

Query Sepolia Archive Node

Check Block Number

curl -H "Content-Type: application/json" \
-X POST --data '{"jsonrpc":"2.0", "method":"eth_blockNumber", "params":[], "id":1}' http://localhost:8545

# Response should have a different "result" value.
{"jsonrpc":"2.0","id":1,"result":"0x754ee0"}
