cfzone

This is a utility to update a cloudflare zone based on a bind-style zone file.

Limitations

Only A, AAAA, CNAME, MX, and TXT records are supported.

Cloudflare supported record types LOC, NS, SRV, SPF and CAA are not currently supported.

Flags exist to skip SRV and SPF types.

Cloudflare supports (at least) two modes not easily representable in a BIND zone. To support these features a few magic TTL values are used.

TTL	Status
-autottl (0)	Automatic TTL, DNS only
-cachettl (1)	Automatic TTL, DNS and HTTP proxy (CDN)
Other values	Set as TTL, DNS only

Pull requests welcome :-)

Running cfzone

cfzone need two environment variables:

• CF_API_KEY - Your API key from Cloudflare
• CF_API_EMAIL - Your Cloudflare email address.

Run cfzone as with the following command: cfzone [-leaveunknown] [-yes] <zonefile>

Available optional flags:

Flag	Description
-leaveunknown	Don't delete unknown records
-yes	will cause cfzone to continue syncing without confirmation.
-autottl <int>	Specify the TTL to interpret as 'Auto' for Cloudflare (default 0)
-cachettl <int>	Specify the TTL to interpret as 'Cache' for Cloufdlare (default 1)
-ignorespf	Skip SPF records in the BIND zone file rather than erroring
-ignoresrv	Skip SRV records in the BIND zone file rather than erroring
-origin	Specify zone origin to resolve @ at the top level

Building

You'll need a working Go environment to build cfzone.

go get github.com/cego/cfzone should retrieve the source code, build it and place the binary in $GOPATH/bin/cfzone.
