Any ports used in docker will be open on your computer and accessible to any device in your network.

However, to open up a port to the internet, you’d have to do port-forwarding on your router. If you haven’t done that, any incoming connections will just be dropped at the router-level.

That’s actually so cool and the more I think about it the more it’s making me really want to host my own Lemmy instance. Can I ask what sort of hardware resources you’re running it on?

I’m reading it so I’d say it works!
