ddns

Purpose

This project essentially is continuously running code that updates your primary DNS record in Cloudflare.

While some might argue that a cronjob could be better suited for this, I believe that the container uses such a small amount of resources that you can only benefit by having it run all the time.

Using this program

Cloudflare

Some environment variables are required:

• ACCOUNT_TOKEN - The API token for your Cloudflare account.

OR

• API_KEY - The API Key for the Cloudflare account
• ACCOUNT_EMAIL - The Cloudflare account email address

Program Arguments

Container Mode

1. --zone-name: The name of the zone you wish to modify.
2. --record-name: The name of the record you wish to modify inside your zone.
3. --provider: The provider you wish to use can be: ipify, icanhazip, icanhaz. Anything other than these three will be considered as "random"
4. --ticker: Directly uses Golang's implementation of time.Duration. Default is "3m", you can set this to whatever you'd like.
5. --create-missing: This will create the missing DNS record in the target if set to true, it is false by default.
6. --record-ttl: This will set the DNS record to this TTL. 300 by default.

Serverless Mode

Does not use pflag library, set the environment variables above for Cloudflare and these

ZONE_NAME=<your name name>
RECORD_NAME=<your record name>
