might be too dumb to ask. I was going through taint and tolerations and bit confused with the command kubectl taint nodes node1 app=blue:NoSchedule. What does the key value app=blue represents? what does this mean? Can someone please help me with it. Say I have a worker node that needs to be tainted!
You specify a toleration for a pod in the PodSpec. Both of the following tolerations “match” the taint created by the kubectl taint line above, and thus a pod with either toleration would be able to schedule onto
- key: “key1”
