How to verify that my cluster is using routes

Question

I have created a routes-based cluster as specified in  https://www.edureka.co/community/59209/how-to-create-a-routes-based-cluster-on-gcloud. How do I verify that my cluster is using routes?

Answer 1

• List your cluster nodes:

kubectl get nodes

• The output shows the names of your nodes:

NAME                                 STATUS   ...     AGE    VERSION
gke-xxx-default-pool-83e239a7-kcg8   Ready    ...     42m    v1.9.7-gke.6
gke-xxx-default-pool-83e239a7-qm6b   Ready    ...     42m    v1.9.7-gke.6
gke-xxx-default-pool-83e239a7-wnrq   Ready    ...     42m    1.9.7-gke.6

• List your routes:

gcloud compute routes list

• In the output, in the NEXT_HOP column, look for the name of one of your cluster nodes:

NAME                 NETWORK        DEST_RANGE         NEXT_HOP
...
[ROUTE_NAME]         default        10.24.0.0/24       [YOUR_NODE_NAME]
...

In the output, you can see that the route provides a next hop for any packet that is destined for a particular Pod address range.
