Why ionic does not have an official Docker container ?

What would you suggest putting in it?

Maintain the version of Ionic ecosystem dependencies (Ionic, Cordova, Android SDK, Java, Node, NPM, etc.). Kind of like how App Flow works but in a shared environment for developers to work with. Is this possible using Docker or something similar other than running a full VM? Also would this be possible for developing both Android and iOS app using Docker or something similar? Essentially looking for something similar to what the OP asked which is an Official Docker Container for Ionic Development configuration. Thanks.
