制作一个节点的镜像

[email protected]:/home/ucsmy# docker run -it –name ubueth -p 8020:8020 ebcd9d4fca80
然后需要更新一下包

apt-get update

准备工作

apt-get install python-software-properties
 apt-get install software-properties-common
 apt-get  install  vim 

安装geth

 add-apt-repository -y ppa:ethereum/ethereum
 apt-get update
 apt-get install ethereum

mkdir private-geth
cd private-geth
vim genesis.json

{
    "config": {
        "chainId": 12345,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
    "coinbase" : "0x0000000000000000000000000000000000000000",
    "difficulty" : "0x400",
    "extraData" : "0x123456",
    "gasLimit" : "0xffffffff",
    "nonce" : "0x0000000000000042",
    "mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "timestamp" : "0x00",
    "alloc": { }
}

初始化geth并且进入geth

geth --datadir ./data init genesis.json
geth --identity "haha"  --nodiscover  --datadir ./data --networkid 12345  --rpcapi "db,eth,net,web3" --port 2221 --rpcport 3331 console

先跑一个容器

docker run –name test1 -it daocloud.io/ubuntu /bin/bash

然后在容器里面更新一下

[email protected]:/# apt-get update -y
1
1
退出容器，commit一下

[email protected]:~$ docker commit test1 daocloud.io/ubuntu/test1
sha256:b7f27fa969f5eb592625e673c16b2f2dda1e31bcdbeb8d29644e41e61645c03a

[email protected]:/home/ucsmy# docker run -it –name ubueth -p 8020:8020 ebcd9d4fca80

docker commit ubueth ebcd9d4fca80/ubueth
