Question: About SSL, LE and Cert-Manager

[atmosx]

Describe your question

The operator does not support automatically configuring DNS resolution for Redis or Sentinel. Since Sentinel returns IP addresses, using public CAs like Let's Encrypt or ZeroSSL is not feasible.

A built-in alternative is to use cert-manager's issuer with a self-signed certificate, requiring clients to use certificates to connect to Redis and Sentinel.

Are there any scenarios where public CA-issued certificates can be used with cert-manager and the Redis operator?

What version of redis-operator are you using?

redis-operator version: v0.18.0

Additional context

Trying to figure out supported SSL stories and their trade-offs.
