To develop driver program, we need /lib/modules//build directory. But I found under docker image of centos, even after I
yum install kernel-devel
There's still no such a directory with all its contents. Question:
(1) how to make it possible to develop driver in a docker linux environment?
(2) is it possible to load this developed module?
Docker is not virtual machine.
Ubuntu with docker is not real ubuntu.
If you want to develop with ubuntu, you should use virtualbox or vmware.
