install:

git clone https://github.com/lance-e/gocker.git
cd gocker
mv ./image/busybox.tar /root/

(attention:should put the image's tar file in the /root/.you could try use docker export the image into /root/,and use gocker to build container by this image)

simply display

go build .
root@localhost:/home/longxu/gocker# go build .
root@localhost:/home/longxu/gocker# ./gocker run -it --name=testcontainer busybox sh
