## 下载二进制包：
wget  https://github.com/kubeedge/kubeedge/releases/download/v1.3.0/kubeedge-v1.3.0-linux-amd64.tar.gz

## 准备配置文件
tar xf kubeedge-v1.3.0-linux-amd64.tar.gz
cd kubeedge-v1.3.0-linux-amd64/cloud/cloudcore

## 创建配置文件
使用命令创建最小配置 ./cloudcore --minconfig > /etc/kubeedge/config/cloudcore.yaml

或带有命令的完整配置 ./cloudcore --defaultconfig > /etc/kubeedge/config/cloudcore.yaml
