I have a DuckDNS hostname that supports DNS txt records for Let's Encrypt DNS validation, as my ISP blocks WAN ports 80 and 443.
I would like to use this LSIO Let's Encrypt docker image but I could not figure out how to use it with DNS validation for DuckDNS.
As a workaround, I'm using the LSIO Nginx-only docker image with the tweaks outlined here to make it as close as possible to the LE image and I installed acme.sh on the host which supports DNS validation for DuckDNS and creates the correct certs for the Nginx docker to use.
However, like the LE image, I would much prefer to use a single docker image to perform this task and keep the host as clean as possible.
The Let's Encrypt docker looks ideal, is it possible to use DuckDNS DNS validation with this image? It appears to support DNS validation for other providers, but I can't see a way to use it with DuckDNS.
