Specify custom IP for DNS records

[vikas027]

What happened:
My kubernetes ingress defaults to the private IP of an internal load balancer. My setup looks like this

Azure Application Gateway (Public IP) --> Azure Firewall --> Azure Internal Load Balancer --> K8s Nginx Ingress Controller ---> K8s Nginx Pods

I tried using externalIPs but the controller still created the Cloudflare DNS record with an internal IP 192.168.1.10 and not the public IP 52.164.208.127.

❯ k get ing
NAME        CLASS      HOSTS                 ADDRESS        PORTS     AGE
vikas       nginx      vikas.example.com     192.168.1.10   80, 443   9d

What you expected to happen:
I expected the operator to create the DNS record with the public IP 52.164.208.127.

How to reproduce it (as minimally and precisely as possible):
Try using externalIPs in the helm values file.

Workaround
My workaround (after a few hours of Google-ing) was to add an annotation to the ingress external-dns.alpha.kubernetes.io/target: "52.164.208.127". Once, I updated the ingress resource with this annotation, the controller created the DNS record with the public IP.

Anything else we need to know?:

Environment:

• External-DNS version (use external-dns --version): 8.6.0
• DNS provider: Cloudflare
• Kubernetes: Azure Kubernetes Engine
• Ingress Controller: Nginx
• Load Balancer: Azure Internal Load Balancer
