Write Dockerfile

Write a Dockerfile

CMD /usr/games/fortune -a | cowsay
Build an image from your Dockerfile
docker build -t feng003/test . (注意最后有个点 .)
docker run feng003/test

Delete images

  1. 停止所有的 container

    docker ps -a -q // 994ecc0d5205 sudo docker stop 994ecc0d5205

  2. 删除 images，通过image 的id来确定删除

    docker images sudo docker rmi
