We’ve just released Kirby CLI 1.5.0 
https://github.com/getkirby/cli/releases/tag/1.5.0
It’s a small release but with a pretty important new feature. You can now set the new KIRBY_HOST environment variable before running the command to make sure that the correct host config is loaded.
This is very handy if you have custom cache setups or other options that might be relevant for the commands.
