Pods didn't trigger scale-up

This operator is what I need! Thank you for your work!

Trying to test based on your example, just slightly modified it for my test cluster. Node pool is successfully created but pod is not scheduled. Could you please check what's wrong?

Error: 0/3 nodes are available: 1 node(s) had untolerated taint {dgolubets.github.io/managed-node-pool: eee41d49-82a4-4b0b-8488-7e11d8081e77}, 2 node(s) didn't match Pod's node affinity/selector. preemption: 0/3 nodes are available: 3 Preemption is not helpful for scheduling
