I'm looking for advice on managing both our on-premises Kubernetes cluster and our cloud cluster within my company. I want to handle deployments and pod management across both environments with a single command, similar to using kubectl. It would be ideal if new pods could automatically be deployed to the cloud cluster when the on-prem cluster runs low on resources. Additionally, I'd like to set it up so that if there are issues in one cluster, it can failover to the other. I came across an open-source tool called Karamada but I'm unsure about its stability or real-world use cases. Has anyone had experience with it, or can you suggest a good framework or solution for managing multi-cluster scenarios? Thanks!

Rancher is a great option for managing multiple clusters, and pairing it with ArgoCD or Flux for deployment can really streamline your process. They allow for handling deployments across clusters effectively. You just need to ensure that you've set everything up correctly to manage resource distribution and failover scenarios.
Thanks for the input! I'm not too familiar with Rancher or Fleet though. How would I go about organizing it to ensure that if one cluster gets overwhelmed, the pods can shift over to another cluster?
