Hey all,

I am hosting applications on my home network via a raspberry pi in
docker containers and I do not want to expose them over the internet.
I’m trying to figure out how to configure my home network so that I
can route requests going to “api.pi” to my web API running on my
RaspberryPi and route “application.pi” to my web application. I’m not
familiar with how home network and host names work, so looking for
some guidance on how to get this setup.

Look up similar posts about internal DNS. You will get a lot of
answers.

Also spend a few minutes on YouTube learning about DNS. Amazing
technology, very simple and fundamental but also the root of many home
lab problems.

I’ll take a peak on other posts about internal DNS.

Do you have any recommendations for learning about DNS on a home
network and configure it? I understand a DNS Server as being similar
to an address book. You give it a hostname and DNS is able to resolve
the ip of where it resides.

I recommend Mr messers network+ YouTube course. You'll learn a lot
more than just DNS and come out much better for it. The certificate
isn't bad either if you want to pursue that, but his material is great
and packaged in short components for easy consumption.

You’ll want a reverse proxy if you have multiple applications running
on one Pi. You will also want a wildcard DNS entry pointing to the Pi
for when you have the reverse proxy working

Yup, that makes since. I feel like since I have pi.local resolving to
my raspberry pi on my home network then all I need to do is setup a
reverse proxy with nginx or something that maps requests to my API or
to my web application. What do you think? Or am I missing a step?

No yeah that’s all you need! NGINX I’d recommend for sure
