互联网技术EOS团队正式发布测试版本，开发者可以利用接口创建合约。本文主要介绍如何用Docker方式安装，主要因为作者用Mac原生机器安装时，出现各种问题。Docker完美解决本地环境影响。
注意：下面是ubuntu环境下安装Docker，如果是Mac环境，请自行搜索Mac环境安装Docker。
Docker安装
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
apt-cache policy docker-ce
sudo apt-get install -y docker-ce git
sudo systemctl status docker
生成Docker的eos镜像文件（这里Ubuntu和Mac一致）
git clone https://github.com/EOSIO/eos
cd eos/Docker
cp ../genesis.json .
注意我们要在ini配置文件做改动
nano config.ini
加入下面
plugin = eos::chain_api_plugin
这里需要注意官方的DockerFile，我们需要做改动，make install因为docker对内存的限制，我们需要将make -j4改为make -j2。避免编译时内存管理问题。
还有一点，编译eos时会提示Could NOT find GMP (missing: GMP_LIBRARIES GMP_INCLUDE_DIR)，也就是gmp这个包没装上，需要我们编译安装
修改Dockerfile后代码如下：

运行
sudo docker build --rm -t eosio/eos .
如下图所示build成功
生成eos的容器
sudo docker run --rm --name eos -d -p 8888:8888 -p 9876:9876 eosio/eos
sudo docker logs --tail 10 eos # 检查日志
测试
执行
sudo docker exec eos /opt/eos/bin/eosc info
