When using the Glances Docker, it runs on "Alpine Linux" OS. If you want to fake the information and show the host operating system you can add the following option to the docker exec command line: -v /etc/os-release:/etc/os-release:ro

mount volume works, but i think this behavior is a little weird.

@s0urcelab
This would be the expected behavior if you run official glances images through docker.

Maybe we could add this volume mount detail in the docker readme file?

@RazCrimson Good advice! It would be helpful if we can add this description in document.
