Private Link connect to Redis Cache

Question

Hello,
we are currently trying to setup a redis instance connected with a private link as described here https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-private-link
Our problem here is, that after enabling the private link + disabling public access to the redis instance, the hostname of the instance my-instance.redis.cache.windows.net  does still map to a public IP and not the private ip of the private link.
As by the FAQ entry, the "privatelink.redis.cache.windows.net" zone should not be used for redis, so we were expecting that the hostname would switch to returning the internal IP.
Could you let us know how the redis host must be configured to be accessible via normal hostname with the private ip?

Answer 1

To access the Redis instance via the normal hostname with the private IP, you'll need to add a custom DNS entry that maps the Redis instance hostname to the private IP address of the Private Endpoint.

1. Get the private IP address of the Private Endpoint.
2. Create a DNS A record mapping my-instance.redis.cache.windows.net to the private IP.

This will ensure that when you use the hostname, it resolves to the private IP within your virtual network.
