Copy the Docker Compose configuration below and then run:

services:
  geth-sepolia:
    container_name: geth-sepolia
    image: ethereum/client-go:stable
    restart: unless-stopped
    command:
      --sepolia
      --http
      --http.addr=0.0.0.0

2. Run the Node

docker compose up -d

3. Wait for Sync

Check your node’s sync status by running:

curl -X POST \
  --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' \
  -H "Content-Type: application/json" \
  http://127.0.0.1:8545
