How to set NodeSelector using jaeger operator

[ErikXu]

I am using jaeger operator v1.22.0 to create jaeger instance.
I want to set NodeSelector for modules like collector, query and agent.
But I haven't found out the place after reading these two links:

https://www.jaegertracing.io/docs/1.22/operator/#updating-a-jaeger-instance-experimental

https://github.com/jaegertracing/jaeger-operator/blob/v1.22.0/pkg/apis/jaegertracing/v1/jaeger_types.go#L129

Please help to provide some examples.
Thanks!

The suggested way is to use affinity/tolerations instead. Is there a reason to use node selectors instead?

Thanks for replying. After reading the doc of kubernetes again, I found I had a wrong concept of affinity before. It can really use affinity instead of node selectors in my scenarios.
