Parts of the host filesystem may be mounted underneath the new process' root filesystem, e.g.

Instead of using the host's root filesystem, mount a different filesystem on / (usually one supplied with the container's image).

(These are passed on to any child processes started by the containerized process.) Typical restrictions and changes include: The difference between a "containerized" process and an ordinary process is the restrictions put on the containerized process and the changes to how it sees the environment around it. Instead, Docker starts processes in your existing OS, just like you start new processes from the command line. The key thing to understand is that a Docker container is not a virtual machine: it doesn't create a new virtual computer on which to run the software. "Containers" Are Just Process Configuration If your host kernel is "compatible enough" with the software in the container you want to run it will work otherwise, it won't. Docker never uses a different kernel: the kernel is always your host kernel.
