Im sure this has been asked before i juat can’t find where it has been - Maybe need to work on how to search Lemmy better. But…

Id like to eventually self host some sevices that require external access. While I have IpV6 addresses my IPV4 is dynamic.

Whats the best free way to be able to point some domains/ subdomains I have to my external dynamic IP and keep it updated. Im running OpenWrt on my router. - So possibly should be posting there.

Free Dyndns services seem to be a bit crap. Do I need to pay for a VPS? (seems to defeat the point of self hosting)

    Cloudflare has an api for easy dynamic dns. I use oznu/docker-cloudflare-ddns to manage this, it’s super lightweight:

    docker run \
  -e API_KEY=xxxxxxx \
  -e ZONE=example.com \
  -e SUBDOMAIN=subdomain \
  oznu/cloudflare-ddns

    Then I just make a CNAME for each of my public facing services to point to ‘subdomain.example.com’ and use a reverse proxy to get incoming traffic to the right service.
