How do I correctly set a nodeSelector for an etcd pod in a Helm chart?

I'm trying to ensure that my etcd pod launches on a specific node within an Availability Zone (AZ) where my persistent volume is located by setting a nodeSelector label. I've used the following Helm command, but the etcd pod still launches on the incorrect nodes in the wrong AZ:

  --set tags.etcd=true \
  --set etcd.labels.nodeSelector=us-west-2a \
  ... \
  risingwavelabs/risingwave```

I've added the `nodeSelector` label to the node and the etcd pod, but it's not being honored. What am I doing wrong?

I think I've misunderstood how to use nodeSelector. I added a label with the key nodeSelector to the pod, but it seems that nodeSelector is actually a field, not just a label. I need to correctly set the nodeSelector field to match the label on the node. Here's what I found in the pod description, which shows that no node selector is currently set:

Node-Selectors:  <none>```

I need to adjust my Helm command to properly set the `nodeSelector` field.
