I have made a service.yaml and have created the service.
kind: Service
apiVersion: v1
metadata:
name: cass-operator-service
spec:
type: LoadBalancer
ports:
- port: 9042
targetPort: 9042
selector:
name: cass-operatorIs there a way to check on which pods the service has been applied?
I want that using the above service, I connect to a cluster in Google Cloud running Kubernetes/Cassandra on external_ip/port (9042 port). But using the above service, I am not able to.
kubectl get svc shows
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
cass-operator-service LoadBalancer 10.51.247.82 34.91.214.233 9042:31902/TCP 73s
So probably the service is listening on 9042 but is forwarding to pods in 31902. I want both ports to be 9042. Is it possible to do?
You can get pods by querying with selector like following
kubectl get pods -l name=cass-operatorYou can also list all pods which are serving traffic behind a kubernetes service by running
kubectl get ep <service name> -o=jsonpath='{.subsets[*].addresses[*].ip}' | tr ' ' '\n' | xargs -I % kubectl get pods -o=name --field-selector=status.podIP=%The best way is follow labels and selectros
Your pod have a label section, and the service use it in the selector section, some examples in:
https://kubernetes.io/docs/concepts/services-networking/service/
You can find the selectors of your service with:
kubectl describe svc cass-operator-serviceYou can list your labels with:
kubectl get pods --show-labels
