Self hosted services with SSL cert (self.selfhosted)
submitted 1 year ago by root to c/selfhosted

So, I have a few services (Jellyfin, Home Assistant, etc) that I am running, and have been acessing via their IP's and port numbers.

Recently, I started using NGINX so that I could setup entries in my Pi Hole, and access my services via some made up hostname (jellyfin.home, homeassistant.home, etc).

This is working great, but I also own a few domains, and thought of adding an SSL cert to them as well, which I have seen several tutorials on and it seems straight forward.

My questions:

  • Will there be any issues running SSL certs if all of my internal service are inward facing, with no WAN access? My understanding is that when I try to go to jellyfin.mydomainname.com, it will do the DNS lookup, which will point to a local address for NGINX on my network, which the requesting device will then point to and get the IP of the actual server.

  • Are there risks of anything being exposed externally if I use an actual CA for my cert? My main goal is to keep my home setup off of the internet.

i have a similar setup at home. the way i did it was using certbot and dns verification. i pointed my domain's NSs to digitalocean's NS and then i downloaded the certbot-digitalocean-dns plugin, created an API key for DO and stored it somewhere and then certbot took care of everything else. nothing is exposed to the internet

Very nice! And you don't have to worry about adding the cert to each device that wants to use the service, right? Since this isn't a self hosted CA.

exactly. that was the main thing i wanted to avoid. i also have nginx-proxy-manager in front of all my apps which also automates some things (like requesting new certs or renewing them when the time comes)
