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?

    You are getting a lot of mentions for LetsEncrypt, which is probably your best bet if you want free, just note that certificates are limited to 90 days. That means you either need to manually update your certificates every 3 months or ensure you have automation in place to do it.

    Not saying it’s impossible, just letting you know that’s one of the trade offs for getting the cert for free.
