It still works the same as it ever did, the only issue(s) recently are docker version is that far out Sonarr won’t work unless you go with an older version number and if you were/are on Hetzner, either a DNS change or hard coding a host IP was required to avoid blocking. Both issues are trivial to work around and while the former is very much PG specific due to the version of docker hard coded, the latter affected Hetzner specifically.
