Centos8 does not have this parameter, the solution is: remove the fast parameter, it is ok

The underlying principle
-
How does Docker work?
Docker is a client-server structure of the system, Docker daemon on the host. Access from client through Socket!
DockerServer receives the instruction from docker-client,
- Why is Docker faster than VM?
- Docker has fewer layers of abstraction than virtual machines
- Docker mainly uses the kernel of host computer, and VM requires Guest OS
So when creating a container, Docker doesn’t need to reload an operating system kernel like a virtual machine, avoiding booting
