Moving from MacOS app to docker setup, due to update issues

Hi All, I’m looking to move from the MacOS app to docker, mainly because of the complexity of auto update becoming more challenging with the forced depreciation of Sonarr (and Radarr) in brew (my auto update script just becomes far more difficult than it should later in the year).

I’ve read that some kind of native container is key, also that my migration would be fairly simple as I can keep the same configuration files (just need to change config and content mapping).

Has anyone actually done this? Any words from the wise.

(I’ve tinkered with Docker a little bit, but largely a novice)

Thanks in advance for any help.
