If you have specific intentions for a Kubernetes node pool/group (workload isolation, cpu type, etc.), then you can assign labels to attract workloads in conjunction with taints to repel workloads that do not have explicit tolerations applied. And although the generalized kubectl utility can assign labels and taints to specific nodes, the assignment of labels … Kubernetes: targeting workloads to a node pool/group using taints and tolerations

GKE: show pod distribution across nodes and zones

Whether you are working on scaling, performance, or high-availability, it can be useful to see exactly which Kubernetes worker node that pods are being scheduled unto. Pods as distributed across worker nodes ns=default kubectl get pods -n $ns -o=custom-columns=NAME:.metadata.name,NODE:.spec.nodeName Pods as distributed across zones (GKE specific) If you wanted to take it one step further … GKE: show pod distribution across nodes and zones
