Feature Request: streamlined install of `docker app` plugin

[aaronsteers]

Description

I notice that docker app 0.8 is now out of release candidate and supported by non-edge installs of docker-ce. In order to make docker app accessible to less technical audiences, it would be extremely helpful to have a more streamlined install experience which does not require PowerShell on Windows.

Would it be possible to publish the install scripts to a package manager such as chocolatey.org (for Windows) and brew.sh (for Mac)? Or alternatively, something like docker plugin install docker-app?

The docker app interface gives us developers a way to reach less-technical audiences who are not comfortable managing docker-compose files or multiple CLI args. I'd like to reach these users (or at least start to pilot to them, but I feel that I will quickly become blocked by the install experience as it exists today.

Any assist, roadmap features, or ideas to streamline?

Thanks!

Steps to reproduce the issue:

Search for instructions to install docker app (specifically for windows but similarly for mac).

Describe the results you received:

Instructions requires running advanced commands through powershell, preceeded by either customization of Docker settings through a UI or via an environment variable which would need to be set globally.

Describe the results you expected:

Would love to have a simpler "one-step" install experience which I can share with non-technical audiences who can benefit from docker apps but are not yet familiar with docker.

Additional information you deem important (e.g. issue happens only occasionally):
