區塊鏈技術EOS測試版Docker方式安裝指南
互聯網技術EOS團隊正式發佈測試版本，開發者可以利用介面創建合約。本文主要介紹如何用Docker方式安裝，主要因為作者用Mac原生機器安裝時，出現各種問題。Docker完美解決本地環境影響。
注意：下面是ubuntu環境下安裝Docker，如果是Mac環境，請自行搜索Mac環境安裝Docker。
Docker安裝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鏡像檔（這裡Ubuntu和Mac一致）
git clone https://github.com/EOSIO/eos
cd eos/Docker
cp ../genesis.json .
注意我們要在ini設定檔做改動
nano config.ini
加入下面
plugin = eos::chain_api_plugin
這裡需要注意官方的DockerFile，我們需要做改動，make install因為docker對記憶體的限制，我們需要將make -j4改為make -j2。避免編譯時記憶體管理問題。
還有一點，
修改Dockerfile後代碼如下：

sudo docker logs --tail 10 eos # 檢查日誌
執行
sudo docker exec eos /opt/eos/bin/eosc info
