1、git clone https://github.com/zhuifengshaonianhanlu/pikachu
2、docker build -t pikachu .
ps:报错，unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /root/Dockerfile: no such file or directory
此时需要先：
cd pikachu
sudo mv Dockerfile dockerfile
然后就可以成功执行啦
3、启动镜像，docker run -d -p8080:80 pikachu，记得初始化哦，完成后就可以访问线上靶场啦
