The docs are great about explaining how to set a taint on a node, or remove one. And I can use kubectl describe node to get a verbose description of one node, inclu
kubectl describe node
kubectl get nodes -o json | jq '.items[].spec'
which will give the complete spec with node name, or:
kubectl get nodes -o json | jq '.items[].spec.taints'
will produce the list of the taints per each node
