I'm trying to deploy Geth(ethereum/client-go) pod on k8s.
But I can't deploy the pod with error "Fatal: Error starting protocol stack: listen tcp: lookup "192.168.1.10": no such host".
My deploy.yaml is here.

Fatal: Error starting protocol stack: listen tcp: lookup "192.168.1.10": no such host
When I turned off the - "--http" - "--http.addr=\"192.168.1.10\"" - "--http.port=8545" settings, the pod works without any problems. The pod begins syncing. nping to 192.168.1.10:30303 works without any problems. So I think the format of NodePort setting is correct. I wonder why the pod can't be started only when I add the series of --http settings.
I have already changed the range of port of k8s. So I think the port 30303 and 8545 are not wrong.
I'd like to know where to fix it or the cause of the error.

Your deployment is missing a label:
apiVersion: apps/v1
kind: Deployment
metadata:
name: gethnodedeployment
needs to become
apiVersion: apps/v1
kind: Deployment
metadata:
name: gethnodedeployment
labels:
name: gethnode
The label is what the service selector uses to find matching pods.
