Resource placement

[dsogari]

The Kubernetes Cluster Federation project (KubeFed) allows configuration of resource placement in federated clusters. This means, e.g., that I can choose in which clusters a workload resource should take place.

Liqo, on the other hand, provides "a unified and coherent view of your clusters". In that regard, I wonder if the placement behavior could be achieved by means of Kubernetes' node affinity/taint concepts?

For example, I could set a taint on all of a cluster's nodes like so: kubectl taint node -l cluster=C1 dedicated=foo:NoSchedule. Then, no application would be deployed on cluster C1, except if a corresponding toleration is applied to the pod template of the application deployment. Does this make sense?

Hi @dsogari, welcome! Yes, the taint/tolerations mechanism is completely compatible with Liqo, since the Liqo virtual node is seen as a normal node by the Kubernetes control plane.

Hi @palexster, thanks! I joined your Slack workspace and I'm going to follow new developments through there.
