I’ve got a staging site running on a tailscale 100.x.y.z address. It’s behind traefik (which does https with dns). It’s got real SMTP credentials. I’m not quite sure how it would work with their magic https certs.
There is none. You’re mostly on your own.
You can skip the checks in discourse-setup (which you shouldn’t bother to use–you’ll need to configure your app.yml by hand), but you can’t skip the requirements.
Right. You can’t use discourse-setup. You’ll need to configure stuff by hand. I guess you should be able to use the --skip-connection-tests and other such switches, but discourse-setup is designed for simple standard installs, and this isn’t one.
You might try using mailhog so you can get email.
You might also skip email altogether and use rake admin:create to set your password.
