EOS开发：通过docker快速构建安装EOSIO

先决条件

Docker: Docker管理服务。Docker旨在通过使开发人员在容器内很方便的创建完全配置的系统环境来简化应用程序部署。系统环境包括在配置好的操作系统中运行各种目标应用程序，这些目标应用程序提供你的应用程序需要的所有运行时支持。开发人员在容器内创建所需的系统配置，然后在打包容器进行分发。

1.获取镜像

EOSIO Dev docker镜像是为本地开发而设计的EOSIO软件的编译版本。

从存储库中提取镜像：

docker pull eosio/eos-dev

开启EOSIO节点

docker run --rm --name eosio -d -p 8888:8888 -p 9876:9876 -v /tmp/work:/work -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev  /bin/bash -c "nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::wallet_plugin --plugin eosio::producer_plugin --plugin eosio::history_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:8888 --access-control-allow-origin=* --contracts-console --http-validate-host=false"

检查它的工作情况：

docker logs --tail 10 eosio

输出应该类似这样：

恭喜！你有一个非常简单的单节点区块链运行在你的docker中！

也可以通过浏览器中的这个地址来检查RPC接口是否工作：

http://localhost:8888/v1/chain/get_info

你应该看到类似的信息：

{
    "server_version": "0961a560",
    "chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
    "head_block_num": 13780,
    "last_irreversible_block_num": 13779,
    "last_irreversible_block_id": "000035d36e1ca29ba378081c574ab3b5ab4214ba29754dd42b512690a9f03e80",
    "head_block_id": "000035d4165c9225d7a04822d142fbcb15f997a6f2571dc7bae8437dea782205",
    "head_block_time": "2018-05-23T16:30:54",
    "head_block_producer": "eosio",
    "virtual_block_cpu_limit": 100000000,
    "virtual_block_net_limit": 1048576000,
    "block_cpu_limit": 99900,
    "block_net_limit": 1048576
}

2.Cleos别名

cleos是一个命令行接口，负责与区块链交互并管理钱包。

为了方便起见，我们将创建一个bash别名，用于运行在容器中的cleos。在终端，运行：

alias cleos='docker exec -it eosio /opt/eosio/bin/cleos -u http://0.0.0.0:8888 --wallet-url http://0.0.0.0:8888'

3.确认是否安装成功

现在试着在你的终端中运行cleos --help。你应该看到一个输出：

Command Line Interface to EOSIO Client
Usage: /opt/eosio/bin/cleos [OPTIONS] SUBCOMMAND

Options:
  -h,--help                   Print this help message and exit
  -u,--url TEXT=http://localhost:8888/
                              the http/https URL where nodeos is running
  --wallet-url TEXT=http://localhost:8900/
                              the http/https URL where keosd is running
  -r,--header                 pass specific HTTP header; repeat this option to pass multiple headers
  -n,--no-verify              don't verify peer certificate when using HTTPS
  -v,--verbose                output verbose actions on error

Subcommands:
  version                     Retrieve version information
  create                      Create various items, on and off the blockchain
  get                         Retrieve various items and information from the blockchain
  set                         Set or update blockchain state
  transfer                    Transfer EOS from account to account
  net                         Interact with local p2p network connections
  wallet                      Interact with local wallet
  sign                        Sign a transaction
  push                        Push arbitrary transactions to the blockchain
  multisig                    Multisig contract commands
  system                      Send eosio.system contract action to the blockchain.

令人惊叹的！我们跑起来了。
