docker-images - docker in docker 是直接在DockerFile 里直接apt-get install ?

Question

我想在docker里用shell处理一些镜像，打包什么的，不想直接装在宿主机上,比如从日本节点编译镜像，然后拉回来再发布到杭州节点.

Answer 1

Yes, it can be so much. Just add the command to install Docker in the RUN command in the Dockerfile. However, using Docker outside of Docker is also a good choice, hanging the docker on the host into the container.
