I have a PC I have installed Portainer on, with various docker services (home assistant, jellyfin, etc…) with an ISP supplied router fixing various device IP addresses and reaching out to dyndns.
I really want to move everything over to HTTPS connections by supplying certificates, tls termination, etc .
The issue I have is self signed certificates mean I have to manage certificate deployment to everything in the house.
I figure I need to link a domain to the DynDNS entry and arrange certs for the domain. However I can’t make the link function and everywhere wants >£100 to generate a certificate.
How are people solving this issue?
I have a public domain that I only use internally on my home network. I have a local DNS server that handles all my internal DNS records. So I just point my DNS records to my nginx proxy manager’s local IP address and let it create certs using DNS Challenge. So I don’t need to expose anything external to make it work.
