Dockerfile

FROM ubuntu
RUN apt-get update && apt-get install -y mysql-server php5 php5-xdebug

创建失败，因为找不到几个包
docker build -t docker_image1 .

E: Package 'php5' has no installation candidate
E: Unable to locate package php5-xdebug

该操作生成了一个没名字的image

无法删除,因为某个容器在用它
docker rmi 77d7 -f
Error response from daemon: Conflict, cannot delete 77d786364eba because the container c4283c57025d is using it, use -f to force

启动容器后,为何连不上?
试过很多次了,都不行。 是否只能删除容器和镜像，不能基于c428镜像做修改么？

刚才明明显示已经启动的，为何连不上呢？
docker attach c428
FATA[0000] You cannot attach to a stopped container, start it first

此时docker ps发现容器停止了。 启动容器成功，连接连不上，同时容器自动停止，这是什么情况？

有人遇到过？
