run一个ubuntu容器，然后自动进入容器

ucsmy@QKTEST21191:~$ docker run -it --name node daocloud.io/ubunturoot@3ac09729dadb:/#

安装geth

sudo apt-get install software-properties-commonsudo add-apt-repository -y ppa:ethereum/ethereumsudo apt-get updatesudo apt-get install ethereum

创建初始块mkdir privategeth && cd privategeth

root@3ac09729dadb:/privategeth# vi 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": { }}

初始化并进入geth

测试功能

用我们自己的镜像创建一个容器代表新节点

ucsmy@QKTEST21191:~$ docker run -it --name node1 daocloud.io/ubuntu/noderoot@976cd835a4d4:/# geth --datadir  ./data --networkid 12345 --rpc console 2>>geth.logWelcome to the Geth JavaScript console!instance: Geth/v1.6.7-stable-ab5646c5/linux-amd64/go1.8.1 modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0

先退出来，我们用shell脚本练练手

vi start.shgeth --datadir  ./data --networkid 12345 --rpc console 2>>geth.logroot@976cd835a4d4:/# /bin/sh start.sh Welcome to the Geth JavaScript console!instance: Geth/v1.6.7-stable-ab5646c5/linux-amd64/go1.8.1 modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0

注意：
运行 Shell 脚本有两种方法：
1、作为可执行程序
将上面的代码保存为 test.sh，并 cd 到相应目录：
chmod +x ./test.sh #使脚本具有执行权限
./test.sh #执行脚本
注意，一定要写成 ./test.sh，而不是 test.sh，运行其它二进制的程序也一样，直接写 test.sh，linux 系统会去 PATH 里寻找有没有叫 test.sh 的，而只有 /bin, /sbin, /usr/bin，/usr/sbin 等在 PATH 里，你的当前目录通常不在 PATH 里，所以写成 test.sh 是会找不到命令的，要用 ./test.sh 告诉系统说，就在当前目录找。
2、作为解释器参数
这种运行方式是，直接运行解释器，其参数就是 shell 脚本的文件名，如：
/bin/sh test.sh
/bin/php test.php
这种方式运行的脚本，不需要在第一行指定解释器信息，写了也没用。

ucsmy@QKTEST21191:~$  docker run -it --name node1 daocloud.io/ubuntu/noderoot@1c31a8a50563:/# cd privategeth/root@1c31a8a50563:/privategeth# geth --identity "haha" --datadir ./data/00 --networkid 12345  --rpcapi "db,eth,net,web3"  --port 2220 --rpcport 3330 consoleWelcome to the Geth JavaScript console!instance: Geth/haha/v1.6.7-stable-ab5646c5/linux-amd64/go1.8.1coinbase: 0xbbe5e5a1e36f018975e99ba3044d448253755a4cat block: 38 (Mon, 07 Aug 2017 09:25:20 UTC) datadir: /privategeth/data modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0miner.start()nullminer.stop()trueeth.blockNumber46>

node2，node3的创建

 docker run -it --name node3 daocloud.io/ubuntu/noderoot@185f7891c3c0:/# vi start.shcd privategethgeth --datadir ./data/00 init genesis.jsongeth --identity "haha" --datadir ./data/00 --networkid 12345  --rpcapi "db,eth,net,web3"  --port 2220 --rpcport 3330 consoleroot@185f7891c3c0:/# /bin/sh start.sh admin.addPeer( "enode://5d1f52b69d7473389e77475a1e972f45215b184ad6734e9b77088f00cc311fe493ed8352359685dee79c64db50041351da60785801328cb5ada82ab206287d1c@172.18.0.2:2220")然后自动更新~                                                                                                                                                                                ~

第四个节点

ucsmy@QKTEST21191:~$  docker run -it --name node4 daocloud.io/ubuntu/noderoot@49970be515bb:/# vi start.shcd privategethgeth --datadir ./data/00 init genesis.jsongeth --identity "haha" --datadir ./data/00 --networkid 12345  --rpcapi "db,eth,net,web3"  --port 2220 --rpcport 3330 --bootnodes "enode://5d1f52b69d7473389e77475a1e972f45215b184ad6734e9b77088f00cc311fe493ed8352359685dee79c64db50041351da60785801328cb5ada82ab206287d1c@172.18.0.2:2220" consoleroot@49970be515bb:/# /bin/sh start.sh

第五个节点连接第二个节点

docker run -it --name node5 daocloud.io/ubuntu/noderoot@49970be515bb:/# vi start.shcd privategethgeth --datadir ./data/00 init genesis.jsongeth --identity "haha" --datadir ./data/00 --networkid 12345  --rpcapi "db,eth,net,web3"  --port 2220 --rpcport 3330 --bootnodes "enode://5d1f52b69d7473389e77475a1e972f45215b184ad6734e9b77088f00cc311fe493ed8352359685dee79c64db50041351da60785801328cb5ada82ab206287d1c@172.18.0.2:2220" consoleroot@49970be515bb:/# /bin/sh start.sh

测试都可以完成，接下来把这个单节点镜像上传到阿里云
首先要在阿里云创建名称空间，创建镜像仓库
然后将镜像推送到registry：

ucsmy@QKTEST21191:~$ docker login --username=15622149705 registry.cn-hangzhou.aliyuncs.comPassword: Login Succeededucsmy@QKTEST21191:~$ docker tag 9ad689891d6d registry.cn-hangzhou.aliyuncs.com/ethblock/ethereum:latestucsmy@QKTEST21191:~$ docker push registry.cn-hangzhou.aliyuncs.com/ethblock/ethereum:latestThe push refers to a repository [registry.cn-hangzhou.aliyuncs.com/ethblock/ethereum]7d1a213def16: Pushed 54242b7256cd: Pushing [============================>                      ] 2.064 GB/3.595 GB33f1a94ed7fc: Pushed b27287a6dbce: Pushed 47c2386f248c: Pushed 2be95f0d8a0c: Pushed 2df9b8def18a: Pushed ^C
