-------------------------------------------------------------------
I currently mainly use Manjaro Linux, but I do have a Mac, so I will say that I
have encountered both usages.
After doing some looking, here is the reasoning docker on Linux and macOS act
differently:
[https://www.amazee.io/blog/post/docker-on-mac-performance-docker-machine-vs-docker-for-mac]
" On Linux systems, Docker directly leverages the kernel of the host system,
and file system mounts are native.
On Windows and Mac, it’s slightly different. These operating systems do not
provide a Linux Kernel, so Docker starts a virtual machine with a small Linux
installed and runs Docker containers in there. File system mounts are also not
possible natively and need a helper-system in between, which both Docker and
Cachalot provide."
I ran `docker build` on my Linux system without sudo and it denied me
permission. I'd assume the Docker daemon runs directly on the Linux system
instead of in a VM, which I'd assume affects how users interact with docker
from the outside.
