I am a firm believer that any self-hosted app should require, at most, a docker-compose.yml and possibly a .env file to get a basic service up and running. Requiring me to clone your repo or run some script from your site doesn't inspire a lot of confidence that it will be easy to maintain and keep up to date, whereas if you provide a prebuilt Docker image, I know that I can always just pull the latest image and be up-to-date.
