Here you go, this will help get you to the HOST OS, and not just SSH’ing into the docker container.
I am by NO means a pro at Hassio, so forgive me for redirecting you to another post about this, but I have been a lurker for years, and have picked up a thing or two about the systems. Also know a bit about docker, so that helps, but again don’t take this as punting you to another person/post, it just explains it better than I can.
