| External-DNS Setup Guide |
ExternalDNS synchronizes exposed Kubernetes Services and Ingresses with DNS providers.
What it does?
Inspired by Kubernetes DNS, Kubernetes' cluster-internal DNS server, ExternalDNS makes Kubernetes resources discoverable via public DNS servers. Like KubeDNS, it retrieves a list of resources (Services, Ingresses, etc.) from the Kubernetes API to determine a desired list of DNS records. Unlike KubeDNS, however, it's not a DNS server itself, but merely configures other DNS providers accordingly—e.g. AWS Route 53 or Google Cloud DNS.
Prerequisites (required for Support on TrueCharts Discord)
- Traefik
- Clusterissuer / Cert-manager installed (vital if exposed externally)
Please follow the Getting Started guide on the Truecharts website.
Installation instructions
This guide will cover 2 scenarios, Cloudflare and Pi-Hole / Pihole, for more external DNS record providers, see External-DNS Docs.
Cloudflare
These instructions taken from external-dns cloudflare tutorial
Step 1
Enter CF_API_TOKEN (preferred) or CF_API_EMAIL/CF_API_KEY
Step 2
Enter preferences for Logs and DNS updates (I suggest >5m to prevent log spam) and select cloudflare as provider and select sources. I find ingress and service covers everything. If you want to filter by multiple domains add your Domain Filter Entry
I recommend using noop for Registry Type and leaving the rest as default, can add DNS Zone filters as necessary as well (see upstream/cloudflare docs).
Step 3
Verify it works, check the logs for updates to DNS records

If this works, you'll see DNS entries inside Cloudflare's DNS page.
PiHole
Step 1
Ignore Provider Credentials, and skip straight to App Configuration and select pihole, add domain filters as necessary
Change to noop for Registry Type and add PiHole Server Address (default is http://pihole.ix-pihole.svc.cluster.local:9089) and PiHole Server Password
Step 2
Verify logs from External-DNS to see if it connects and updates PiHole
