如何使用docker compose进行geth init和geth挖掘?

geth ethereum docker-compose docker

4ntoine · 技术社区 · 8 年前

我想用Docker创建私有以太坊网络。我已经准备了Genesis文件,所以我需要 geth init genesis.json 然后开始采矿 geth --mine ... . 我可以用脚本(比如: https://github.com/vertigobr/ethereum/blob/master/runminer.sh#L5 和 https://github.com/vertigobr/ethereum/blob/master/runnode.sh#L23 ):

if [ ! -d $DATA_ROOT/keystore ]; then
    echo "$DATA_ROOT/keystore not found, running 'geth init'..."
    docker run --rm \
        -v $DATA_ROOT:/root/.ethereum \
        -v $(pwd)/genesis.json:/opt/genesis.json \
        $IMGNAME init /opt/genesis.json
    echo "...done!"
fi
echo "Running new container $CONTAINER_NAME..."
docker run $DETACH_FLAG --name $CONTAINER_NAME \
    --network ethereum \
    -v $DATA_ROOT:/root/.ethereum \
    -v $DATA_HASH:/root/.ethash \
    -v $(pwd)/genesis.json:/opt/genesis.json \
    $RPC_PORTMAP \
    $IMGNAME --bootnodes=$BOOTNODE_URL $RPC_ARG --cache=512 --verbosity=4 --maxpeers=3 ${@:2}

既然这似乎是两个步骤的过程,我怎么能做与Docker组成?

如果我超驰 command: 对于采矿服务,我应该写什么?如果我只是写 geth init ,则不会开始挖掘。如果我试着加入并写作 command: init genesis.json --mine ... 很痛:

version: "3"

services:
  eth_miner:
    image: ethereum/client-go:v1.7.3
    ports:
      - "8545:8545"
    volumes:
      - ${DATA_ROOT}:/root/.ethereum
      - ${GENESIS_FILE}:/opt/genesis.json
    command: init /opt/genesis.json --rpc --rpcaddr=0.0.0.0 --rpcapi=db,eth,net,web3,personal --rpccorsdomain "*" --nodiscover --cache=512 --verbosity=4 --mine --minerthreads=3 --networkid 15 --etherbase="${ETHERBASE}" --gasprice=${GASPRICE}

最好的选择是创建一个shell脚本,该脚本执行初始化,然后运行geth,应该如下所示:

#!/bin/bash
if [ ! -d /root/.ethereum/keystore ]; then
    echo "/root/.ethereum/keystore not found, running 'geth init'..."
    geth init /opt/genesis.json
    echo "...done!"
fi

geth "$@"

和docker-compose.yaml:

version: "3"

services:
  eth_miner:
    image: ethereum/client-go:v1.7.3
    ports:
      - "8545:8545"
    volumes:
      - ${DATA_ROOT}:/root/.ethereum
      - ${GENESIS_FILE}:/opt/genesis.json
      - ./init-script.sh:/root/init-script.sh
    entrypoint: /root/init-script.sh
    command: --bootnodes=$BOOTNODE_URL $RPC_ARG --cache=512 --verbosity=4 --maxpeers=3 ${@:2}
