    eth私链搭建with docker

获取geth image

docker pull ethereum/client-go:v1.8.12
运行geth

docker run -it --rm -v /home/xy/misc/workspace:/workspace --entrypoint /bin/sh ethereum/client-go:v1.8.12
运行geth(指定网络与ip)

docker run -it --rm -v /home/xy/misc/workspace/:/workspace --entrypoint /bin/sh ethereum/client-go:v1.8.12
创建账号4个账号(密码为123456),以写入创世块

准备工作:
docker run -it --rm -v /home/xy/misc/workspace/:/workspace --entrypoint /bin/sh ethereum/client-go:v1.8.12
mkdir -p /workspace/dapp/miner
mkdir -p /workspace/dapp/data
创建账号:
geth -datadir ./data account new

创建创世区块


alloc下面列举了4个账号及默认余额

创建挖矿主节点


创建所有矿工的entrypoint脚本


该脚本的功能是让以太坊节点（容器）自动初始化以太坊网络，并且接受一个自动运行脚本作为输入。

/worksapce/dapp/init.sh
#!/bin/sh
geth -datadir ~/data/ init /workspace/dapp/data/genesis.json

if [  $# -lt 1 ]; then 
  exec "/bin/sh"
else
  exec /bin/sh -c "$@"
fi

创建主节点自动运行脚步

/workspace/dapp/mine.sh
#!/bin/sh
cp -r /workspace/dapp/miner/data/keystore/* ~/data/keystore/
geth -datadir ~/data/ --networkid 88 --rpc --rpcaddr="0.0.0.0" --rpcapi admin,eth,miner,web3,personal,net,txpool --unlock "0x9dbc38e10909caca669ac65a8bcd1f6e29c35c0a" --etherbase "0x9dbc38e10909caca669ac65a8bcd1f6e29c35c0a" console

创建主节点容器


该命令会创建一个持久化的容器。容器的entrypoint和自动运行脚本指定为我们刚创建的那两个脚本。

docker run -it --name=miner --hostname node -v /home/xy/misc/workspace:/workspace -v /home/xy/misc/workspace/dapp/master:/root/data/geth --entrypoint /workspace/dapp/init.sh ethereum/client-go:v1.8.12 /workspace/dapp/mine.sh
创建从矿工节点


从矿工节点启动脚本:

/workspace/dapp/node.sh
#!/bin/sh
cp -r /workspace/dapp/miner/data/keystore/* ~/data/keystore/
geth -datadir ~/data/ --networkid 88 console

启动从矿工

docker run -it --name=node1 --network ethnet --hostname node1 -v /home/xy/misc/workspace:/workspace -v /home/xy/misc/workspace/dapp/slave:/root/data/geth --entrypoint /workspace/dapp/init.sh ethereum/client-go:v1.8.12 /workspace/dapp/node.sh
测试节点RPC

curl 172.16.0.50:8545 -X POST --data '{"id":1,"jsonrpc":"2.0","method":"eth_accounts", "params":[]}' -H "Content-Type: application/json"
