Package: cloudflare-dyndns
CloudFlare Dynamic DNS clientThis is a simple Dynamic DNS script written in Python for updating CloudFlare DNS A records,similar to the classicddclient perl script.You can run it as a cron job or a systemd timer.It only updates the records if the IP address actually changed by storing a
cache of the current IP address.It checks multiple IP services. If one of them doesn't respond, it skips it and check the next.It has an easy to use command line interface.InstallYou can simply install it with pipfrom PyPI:$pipinstallcloudflare-dyndnsOr you candownload a standalone binary from the releases page.Or you can usethe Docker image:$dockerrun--rm-itkissgyorgy/cloudflare-dyndns--helpPlease note that before you can use the-6IPv6 option in Docker, you need toenable IPv6 support in the Docker daemon.
Afterward, you can choose to use either IPv4 or IPv6 (or both) with any container, service, or network.NoteIf you use this script, it "takes over" the handling of the record of those
domains you specified, which means it will update existing records and create
missing ones.You should not change A or AAAA records manually or with other scripts, because
the changes will be overwritten.I decided to make it work this way, because I think most users expect this
behavior, but if you have a different use case,let me know!Command line interface$ cloudflare-dyndns --help
Usage: cloudflare-dyndns [OPTIONS] [DOMAINS]...

  A command line script to update CloudFlare DNS A and/or AAAA records based
  on the current IP address(es) of the machine running the script.

  For the main domain (the "@" record), simply put "example.com"
  Subdomains can also be specified, eg. "*.example.com" or "sub.example.com"

  You can set the list of domains to update in the CLOUDFLARE_DOMAINS
  environment variable, in which the domains has to be separated by
  whitespace, so don't forget to quote the value!

  The script supports both IPv4 and IPv6 addresses. The default is to set
  only A records for IPv4, which you can change with the relevant options.

Options:
  --api-token TEXT   CloudFlare API Token (You can create one at My Profile
                     page / API Tokens tab). Can be set with
                     CLOUDFLARE_API_TOKEN environment variable.  [required]

  --proxied          Whether the records are receiving the performance and
                     security benefits of Cloudflare.

  -4 / -no-4         Turn on/off IPv4 detection and set A records.
                     [default: on]

  -6 / -no-6         Turn on/off IPv6 detection and set AAAA records.
                     [default: off]

  --delete-missing   Delete DNS record when no IP address found. Delete A
                     record when IPv4 is missing, AAAA record when IPv6 is
                     missing.

  --cache-file FILE  Cache file  [default: /home/walkman/.cache/cloudflare-
                     dyndns/ip.cache]

  --force            Delete cache and update every domain
  --debug            More verbose messages and Exception tracebacks
  --help             Show this message and exit.Shell exit codes1: Unknown error happened2: IP cannot be determined (IP service error)3: CloudFlare related error (cannot call API, cannot get records, etc...)Changelogv4.0IPv6 supportNow you can specify-6command line option to update AAAA records too.You can delete records for missing IP addresses with the--delete-missingoption. Seeissue #6for details.There is a new--proxiedflag for setting Cloudflare DNS services.v3.0breaks backward compatibility using the global API KeyYou can only use API Tokens now, which you can create underMy Profile / API Tokens:https://dash.cloudflare.com/profile/api-tokens.
The problem with the previously used API Key is that it has global access to
your Cloudflare account. With the new API Tokens, you can make the script
permissions as narrow as needed.Upgrading from 2.0 and using API Tokens is highly recommended!The--domainsoption is now gone, because it made no sense (it only existed
for reading from the envvar), but you can use theCLOUDFLARE_DOMAINSenvvar
the same as before.v2.0breaks backward compatibility for a PyPI release.The script you need to run is now calledcloudflare-dyndnsand the cache file
also changed. You can delete the old cache manually, or you can leave it, it
won't cause a problem.The Docker file entry point is changed, so if you pull the new image, everything
will work as before.DevelopmentYou can install dependencies with poetry (preferable in a virtualenv).Afterinstalling poetry, simply run:$poetryinstall
