Can Docker be installed in Docker’s container to run again

  docker, question

Since multiple docker image are used as auxiliary during construction, it is thought that running multiple Containers in Containers helps build and delete after completion to ensure the size of the built image.
However, the use of docker in container often fails. I wonder if it is not allowed in implementation.

Clear answer: no, no, no!

If you understand the basic principle of docker implementation, you won’t ask this question. It is suggested to know about linux kernel, such as namespace and cgroup.
