What did you expect to see?

A list of rediscluster objects

What did you see instead?

The IP address 10.206.44.45 is the IP address of the redis-operator pod

Some progress. I did helm install redis-operator --version 0.15.9 ot-helm/redis-operator --namespace redis-operator --set redisOperator.webhook=true --set certmanager.enabled=true

and now I get a new error:

Error from server: conversion webhook for redis.redis.opstreelabs.in/v1beta1, Kind=RedisCluster failed: Post "https://webhook-service.redis-operator.svc:443/convert?timeout=30s": tls: failed to verify certificate: x509: certificate signed by unknown authority

More progress I'm now trying kubectl get rediscluster --all-namespaces --insecure-skip-tls-verify

and am getting this error:

Error from server: conversion webhook for redis.redis.opstreelabs.in/v1beta1, Kind=RedisCluster failed: Post "https://webhook-service.redis-operator.svc:443/convert?timeout=30s": no endpoints available for service "webhook-service"

I encountered the same problem as you.

I was able to fix this by using v1beta2 instead of v1beta1. apiVersion: redis.redis.opstreelabs.in/v1beta2

FayeG2b commented 3 months ago

Good to hear.

I'm finding that I need to provide a X509.3 CA object (base64 encoded) into the webhook configuration of the CRD to get past this when upgrading redis-operator from v11 to v15 with already extant v1beta1 redisclusters deployed in k8s.
I also have to gut the redis-operator's helm chart of cert-manager otherwise it destroys my cluster's ability to use the main cert-manager's clusterissuer configurations.
Then I edit the helm chart so that the webhook asks for a clusterissuer cert rather than a issuer cert.

I'll post more details soon.
