Currently, it is not possible to taint new nodes in a node pool automatically. Deploy this project in your cluster and it'll watch for new nodes via cronjob.

First modify these three files to fit what your k8s cluster:

1. cronjob.yaml - adjust the frequency as you like, it's currently set to run every 15 mins.
2. taint-nodes.sh - change the node pool names and change the taint to what you need.
3. Change the namespace in node-tainter.yaml to what you need, I use default

Then, deploy!

kubectl create -f node-tainter.yaml
