A new ‘app store’ is expected to ship as part of Ubuntu 23.10 when it’s released in October — and it’ll debut with a notable change to DEB support.
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 --rm which 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 the docker group, you have to always invoke with sudo. 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.
