新手通过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:

1
docker pull eosio/eos-dev

开启EOSIO节点

1
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:

1
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:

1
http://localhost:8888/v1/chain/get_info

你应该看到类似的信息:

}

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:

1
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:
