A couple of weeks ago, I set up a Load Balancer on an AKS Cluster. I am using the following script to point a .cloudapp.azure.com domain to the Load Balancer: 

#!/bin/bash

# Public IP address of your ingress controller
IP="<MY_IP>"

# Name to associate with public IP address
DNSNAME="<MY_DNS_NAME>"

# Get the resource-id of the public ip
PUBLICIPID=$(az network public-ip list --query "[?ipAddress!=null]|[?contains(ipAddress, '$IP')].[id]" --output tsv)

# Update public ip address with DNS name
az network public-ip update --ids $PUBLICIPID --dns-name $DNSNAME

The problem is that the FQDN keeps disappearing, approximately every 24 hours. Every day I have to run the script again, and then everything is alright again. Why could this be happening?

I have assigned a static IP to my Load Balancer, which also has not restarted. I used the following command to assign a static ip:

az network public-ip create --resource-group <MY_RG> --name <IP_NAME> --sku Standard --allocation-method static --query publicIp.ipAddress -o tsv

and used this IP in my charts for the nginx controller. The IP keeps pointing to the right place but the domain name keeps disappearing.

Thank you in advance for any advice, greatly appreciated.

  • What do you mean the FQDN disappear? Do you mean the FQDN disappears from the public IP that you assign to the Ingress? Please provide the document that you followed to deploy the Ingress. – Charles Xu Jan 27 '20 at 09:41
  • I see something similar on my end. I provision AKS clusters using ansibles and I use a public IP role to assign a static address to my ingress service and to issue a DNS name. DNS name is being removed automatically after several minutes. – Marat Mar 31 '20 at 00:42
