From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Each container, by default, runs in a separate network namespace. You can use docker CLI to create specific networks that can be shared with other containers, or use docker-compose for it. Technically, for processes outside containers you can still use the same network of that container by running the inside the network namespace of the 'VPN' container (for example running them with unshare). However, I wouldn't recommend this, as containers are supposed to run mostly isolated workload and not for this kind of use-case. But yeah, technically it's feasible.
