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.

Exactly. Docker is very much not an appropriate tool for "CLI apps."
I use it for pandadoc CLI all the time, it's great.
You could do it of course but it's far from ideal for the purpose of a general case CLI. Unless your script yourself a wrapper, the invocation is fairly verbose. It also leaves containers behind unless you specifically pass
--rmwhich isn't default. Then there's the intricacies of the different ways of passing data to it. Oh and let's not forget that unless you setup rootless Docker, or you do something dangerous like adding yourself to thedockergroup, you have to always invoke withsudo. Therefore I wouldn't say that Docker is an appropriate tool for CLI apps in general. For dependency-bundled CLI apps, Snap doesn't have these gotchas and is therefore much closer to ideal CLI UX.
