This is a great feature, thank you 🙂

I like the directionality of this, i.e. it makes it possible to manage this issue from within the plugin itself, not requiring the site admin to do anything per se.

I have a few initial questions:

- Will the existing [`required_version`](https://github.com/discourse/discourse/blob/58e52c0e4fd5fcd35627fa89db48a5719cfa3e45/lib/discourse.rb#L222) plugin metadata check in plugin activation remain? And how do you see that interelating with this (if at all)?

- I see this is added in the form of a rake task atm. How does it relate to, what is the intended use, with `discourse_docker` (i.e. the launcher) and `docker_manager`? I see you’ve made additions to both repos, but could you explain how it’s intended to work in both environments?
