Chapter 8: Node feature selection

8.1.1 Node selectors

View in the book. Buy the book.

Apply the change

kubectl apply -f Chapter08/8.1.1_NodeSelection/deploy_nodeselector-autopilot.yaml

Wait for the Pod. It will require a new node since we’re requring arm64.

watch -d kubectl get pods,nodes

Verify by describing the node which the Pod was assigned

$ kubectl get pods -o wide

                    kubernetes.io/arch=amd64

If you see kubernetes.io/arch=amd64 it was assigned correctly.
