Geth

You must initialize the Execution Layer node with genesis.json first like this:

docker run \
  --rm \
  -it \
  -v $(pwd)/execution-data:/execution-data \
  -v $(pwd)/el-cl-genesis-data:/el-cl-genesis-data \
  ethereum/client-go:v1.14.0 \
  --state.scheme=path \
  --datadir=/execution-data \
  init \
  /el-cl-genesis-data/custom_config_data/genesis.json

Then you can start a Geth node using a command like this in a Docker Compose file:

execution:
    image: ethereum/client-go:v1.14.0
    command:
      - --networkid=648
      - --state.scheme=path
      - --verbosity=4
      - --datadir=/execution-data
      - --http
      - --http.addr=0.0.0.0
      - --http.port=8545
      - --http.vhosts=*
      - --http.corsdomain=*
      - --http.api=admin,engine,net,eth,web3,debug,txpool

      - --ws.port=8546
      - --ws.api=admin,engine,net,eth,web3,debug

      - --bootnodes=${EL_BOOTNODES}
