exclude-prefixes

Test kernel to kernel connection with excluded prefixes

This example shows kernel to kernel example where we excluded 2 prefixes from provided IP prefix range.

NSC and NSE are using the kernel mechanism to connect to its local forwarder.

Requires

Make sure that you have completed steps from basic or memory setup.

Run

Create config map with excluded prefixes

kubectl apply -k ../../../examples/features/exclude-prefixes/configmap

Deploy NSC and NSE:

kubectl apply -k ../../../examples/features/exclude-prefixes

Wait for applications ready:

kubectl wait --for=condition=ready --timeout=1m pod -l app=alpine -n ns-exclude-prefixes

kubectl wait --for=condition=ready --timeout=1m pod -l app=nse-kernel -n ns-exclude-prefixes

Ping from NSC to NSE:

kubectl exec pods/alpine -n ns-exclude-prefixes -- ping -c 4 172.16.1.200

Ping from NSE to NSC:

kubectl exec deployments/nse-kernel -n ns-exclude-prefixes -- ping -c 4 172.16.1.203

Cleanup

Delete ns:

kubectl delete configmap excluded-prefixes-config
kubectl delete ns ns-exclude-prefixes
