None

Problem Description

No response

Solution Description

We have recently added Minio as another remote cache storage, to hold K8sGPT's findings.

In order to have feature parity, it will be great to add it in the operator's config as well

Benefits

Feature parity with K8sGPT

Potential Drawbacks

No response

Additional Information

There is already a GRPC proto schema to support minio S3-like api

and the original PR has included the server mode changes

I would like to take up this issue please,

Also I'm new to this operator ecosystem and trying to find my way,
So I would be grateful if you could please point me what operator's config is.

@arbreezy
hey, I'm new to k8sgpt and would like to contribute to the operator of it.

I am currently working on this feature. I tried to use the S3_cache schema in pkg/client/config.go
by using sth like

if config.Spec.RemoteCache.MinIO != nil {
			req.Cache = &schemav1.Cache{
				CacheType: &schemav1.Cache_S3Cache{
					S3Cache: &schemav1.S3Cache{
						BucketName: config.Spec.RemoteCache.MinIO.BucketName,
						Endpoint:   config.Spec.RemoteCache.MinIO.Endpoint,
					},
				},
			}
		}

But i get this error during reconciliation loop

does this require changing the schema/protobuf ? or changing the server implementation ?

@chetak123 I might be able to create a PR soon, you can have a look at changes and suggest improvements.
