⁠cloudflare-ddns

A docker image to periodically update DNS A record on CloudFlare DNS Service.

⁠Usage

docker run \
    -e API_KEY=xxxxxx \
    -e ZONE=example.com \
    -e SUBDOMAIN=subdomain \
    -e SCHEDULE="* * * * *" \
    lambdalisue/cloudflare-ddns

⁠Environment variables

NameDescription
API_KEYYour CloudFlare scoped API token. Required
ZONEThe DNS zone that DDNS update should be applied to. Required
SUBDOMAINA subdomain of the ZONE to write DNS changes to. If this is not supplied the root zone will be used.
SCHEDULEA cron schedule expression (e.g. * * * * *) to execute DDNS updates

⁠Differences

  • DNS record creation is not supported
  • AAAA record (IPv6) is not supported
  • Pulling IPs from iface is not supported

⁠Thanks

Originally the idea comes from https://gist.github.com/Tras2/cba88201b17d765ec065ccbedfb16d9a⁠. And then I found https://github.com/oznu/docker-cloudflare-ddns⁠ but that's a bit too complicated for my case so manually forked to make simplified version.
