How-To

So you've followed some of our TrueNAS guides, setup your domain name, certificates and use Cloudflare for your DNS management, however you don't have a static IP, then this guide is for you. This quick guide will help you go through the steps to use Cloudflareddns to update your dynamic IP along with your entire deployment so that even if you change IP your domain will point to the right address.

Requirements

Domain name (can be purchased through Cloudflare or etc)

Cloudflare DNS management

Sign up for Cloudflare free
Point your nameservers to the ones Cloudflare assigns to you

Cloudflareddns chart

Prerequisites

This guide assumes you've followed our main Quick-Start Guide with your domain on TrueNAS and done the configuration for your DNS on Cloudflare (see this video on our YouTube channel)

The recommended way is to setup CNAMEs for your subdomains (charts) and keep your A record pointed to your base domain, such as below

To keep things simple, one can simply use the Global API key from Cloudflare that you previously used inside our guides to setup your certificates, in case you forget it's in the page below

Alternatively you can create an API Token, with the following permissions: Click Create Token and Use Template on the Edit zone DNS.

Zone - DNS - Edit

Zone - Zone - Read

And the following Zone resources

Include - Specific zone - yourdomain.com

Cloudflareddns Chart Setup

Step 1-2: Name chart and leave defaults for Step 2

Step 3:

Use Global API key from Cloudflare Domain Overview page (see above) for the CF_APIKEY field

Change CF_USER to your Cloudflare Email Account
Change CF_HOSTS to your DNS Zone A record (mydomain.com)
Change CF_ZONES to the same Zone (mydomain.com)
Change CF_RECORDTYPES to A if you're only changing your main domain

Alternatively (Only if you created an API Token)

Change CF_APITOKEN to your generated Token

Change CF_HOSTS to your yourdomain.com (or the record you want to update)

Change CF_ZONES to your Zone ID (Found in your Cloudflare dashboard, on the right column)

Change CF_RECORDTYPES to A if you want to update an A record

If you're using or changing specific A records or CNAMEs you may want to refer to the upstream documentation for more examples here)

Steps 4-8: Adjust as necessary but defaults are fine

Support
