Create a mixed node cluster. #168

Open Zarquan opened 4 years ago

Zarquan commented 4 years ago

What happens if we add a mixture of different node sizes to a K8s cluster ? Does it work having one or two huge nodes, and lots of small nodes round the edges ?

Can we use taints to influence which Pods go on which nodes ? https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/

No one seems to have thought of this as an option - so it probably means there are good reasons for NOT doing it. All the examples I've found always use the same size of node. https://medium.com/better-programming/tips-for-rightsizing-your-kubernetes-cluster-e0a8f1093d8d

Another example - assumes all the nodes are the same size. https://learnk8s.io/kubernetes-node-size
