Trying to use --all along with the selector is also not supported.

How to reproduce it (as minimally and precisely as possible): kubectl taint nodes -l <any label selectordedicated=foo:PreferNoSchedule Anything else we need to know:
can you post the output of kubectl taint nodes -l myLabel=X dedicated=foo:PreferNoSchedule (((And first of course Make sure that myLabel is on the cluster ....)))
Would you like me to explicitly use the label "myLabel"? Otherwise that's the command and output I posted in "What happened" above. (I had set a label dedicated=foo ahead of time on two nodes.)
Ah ok so the taint k/v is the exact same as the label k/v, that makes the example tricky to parse.... but I agree .... this should work .. I can try to reproduce this....
Yup, the same k/v. (I wanted both labels and taints to determine this set of nodes, and it seemed like it would be confusing to have different k/v's for each. I kinda thought this would be the common case...)
Ah , yeah i see it to ... Even though clearly, the selector exists.
Is the taints and tolerations expert on our team. ravi can you look at ? this logic might be shadowing the label selector, such that its impossible to use labels to select the nodes you're trying to taint.
cc. m i definitely think this is a bug ... ? Looks like the taints maybe are shadowing the label selectors above in

It seems the line is the culprit. Here we are checking for resources if they are 2, the resources allowed are node,nodes,no so if it needs it has to be 1 and this check is already available So, I guess its safe to remove that. I tested that functionality after removing this and it fixed the issue. I will submit a PR for this unless someone has objections.
