Bear in mind all addons are docker containers. That includes the ssh addons. So when you install and connect to the ssh addon you aren’t actually ssh’ing into the host, you’re actually connecting to a docker container running the ssh service.
Also FYI @michaelblight the portainer addon was deprecated and removed from the community addons repo quite a while ago. It is no longer supported since the things it was used for was a constant source of strange issues. And basically everything users could do with it caused systems to become unsupported.
If someone else is maintaining it now you should probably link to it. Since it’s not listed for anyone ootb anymore. But I wouldn’t really recommend it, there’s better ways to get access to your logs in that guide.
