Drone — Cloudflare DNS

Drone plugin to control simple DNS records via Cloudflare's API

About

Our Drone plugin enables the ability for your pipeline to interface with Cloudflare's API to create/update/delete DNS records. This plugin is written in Go and it uses the cloudflare-go package to communicate with Cloudflare's API. For information on Cloudflare's API please refer to their documentation page.

Cloudflare Token

The API token that is used to authenticate with Cloudflare's API can be created in Cloudflare's dashboard. It is recommended to create an API token that includes only the zone resource you want to manipulate and give edit permissions only to the DNS resource.

Build

Develop locally by running the plugin with the following commands. Also please note that you should specify environmental variables for the plugin either via the inline method (FOO=bar go run src/main) or via the export FOO=bar method before the go run command.

$ go mod download
$ go run cmd/main/main.go

Docker

Drone plugins work off of docker images. The following commands will go over building, pushing, and running the docker image for this plugin.

Build Docker Image:

$ docker build -t jetrails/drone-cloudflare-dns .

Run Docker Container:

You can then replicate the command that Drone will use to launch the plugin by running:

$ docker run --rm \
	-e PLUGIN_API_TOKEN="u4C7ev06GMS8_vWBTpjqtVReT3I7FwGpW7MG44ZD" \
	-e PLUGIN_ZONE_IDENTIFIER="eJzrjE44s6Ki67x1tSDJzI8LdXxM3nj7" \
	-e PLUGIN_ACTION="set" \
	-e PLUGIN_RECORD_TYPE="cname" \
	-e PLUGIN_RECORD_NAME="example.com" \
	-e PLUGIN_RECORD_CONTENT="google.com" \
	-e PLUGIN_RECORD_PROXIED="true" \
	-e PLUGIN_RECORD_TTL="3600" \
	-v $(pwd):/drone/src \
	-w /drone/src \
	jetrails/drone-cloudflare-dns

Push Docker Image:

Finally, push this image to our Docker Hub repository (assuming you have permission):

$ docker push jetrails/drone-cloudflare-dns

Usage

There are two values for action, set and unset. If set is choosen and a record does not already exist, then the record is created. If set is choosen and the record already exists, then the record is updated. It is recommended that the record_name value be always set to the FQDN. Please refer to the table below with all possible settings that can be passed to the plugin:

Name	Required	Default	Case-Sensitive	Type
api_token	Yes	-	Yes	STRING
zone_identifier	Yes	-	Yes	STRING
action	Yes	-	No	ENUM[set,unset]
record_type	Yes	-	No	ENUM[a,cname,...]
record_name	Yes	-	Yes	STRING
record_content	action == set	-	Yes	STRING
record_proxied	No	true	N/A	STRING
record_ttl	No	1	N/A	INT
record_priority	No	1	N/A	INT
debug	No	false	N/A	STRING
