Karmada backup and restore

[likku123]

Hello,

Let me start explaining the present setup and what I want to achieve.

Present setup:

I have deployed Karmada via Helm chart in my EKS cluster. I was able to configure my member clusters and can use it via Karmada.

Requirement:

Now I want to migrate Karmada to another EKS cluster because of the various issues in the present EKS deployment.

I am looking around the possibilities on how to migrate Karmada to new EKS cluster without much disruption and loosing the ETCD data.

Any guidance or help regarding the requirement would be highly appreciated

Now I want to migrate Karmada to another EKS cluster because of the various issues in the present EKS deployment.

I'm curious about what kind of issues you are talking about here.

It's not related to Karmada issues. The way our EKS cluster is setup I has some drawbacks . Now we have created new EKS cluster and want to migrate the Karmada to this new cluster

I guess the key thing is migrating the ETCD data, the other components are all stateless.

Yes, One can experience this scenario where they want to migrate the Karmada to a new cluster . I am looking around the Karmada docs if it's documented some where on how to take Karmada backup and restore in case of Disater recovery.

Here is a documentation for backup and restore Karmada resources: https://karmada.io/docs/administrator/backup/working-with-velero

I'm not sure if it still works because no such feedback yet.

by the way, it sounds like you are using Karmada in production now, since you are trying to migrate but destroy and rebuild.

Still we are exploring and bit skeptical to run production grade. One reason we are backing off from Destroy and rebuild is . We have provided access to several projects using namespace scope restriction. We use this cluster for model training and also the bioinformatics pipelines . Where users login to Karmada cluster and execute the jobs
