如何使用Docker快速启动EOSIO环境

EOSIO构架

EOSIO主要包括了:

• nodeos (node + eos = nodeos) - the core EOSIO node daemon that can be configured with plugins to run a node. Example uses are block production, dedicated API endpoints, and local development.
  EOSIO核心后台进程。可以通过设置，来运行一个node。例如：区块链产品，专用API，本地开发。

• cleos (cli + eos = cleos) - command line interface to interact with the blockchain and to manage wallets
  命令行界面接口。用于和区块链交互，管理钱包。

• keosd (key + eos = keosd) - component that securely stores EOSIO keys in wallets.
  用于在钱包里面安全的存储EOSIO私钥。

Basic EOSIO System Architecture

In the sections that follow, you will build the EOSIO components, and deploy them in a single host, single node test network (testnet) configuration.
正如上图所示，你可以组建你的EOSIO部件，并且部署他们到一个服务器上。

Docker启动EOSIO

前提

安装好了Docker

获取Docker Image

docker pull eosio/eos-dev

启动EOSIO

sudo 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"

确认启动

sudo docker logs --tail 10 eosio

~$ sudo docker logs --tail 10 eosio

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