git clone https://github.com/hydrokhoos/nlsr-sample-k8s.git
cd nlsr-sample-k8s

2. Execute the deployment script:

./create.sh

3. Check NLSR status on a specific node:

kubectl exec deployment/ndn-node1 -- /bin/bash -c "nlsrc routing"

Provide Content

1. Create content (e.g. /sample.txt)

kubectl exec deployment/ndn-node1 -- /bin/bash -c "echo 'Hello, world!' > /sample.txt"

2. Advertise content using NLSR

kubectl exec deployment/ndn-node1 -- /bin/bash -c "nlsrc advertise /sample.txt"

3. Provide content

kubectl exec deployment/ndn-node1 -- /bin/bash -c "ndnputchunks /sample.txt < /sample.txt"

4. Request content from another node

kubectl exec deployment/ndn-node3 -- /bin/bash -c "ndncatchunks /sample.txt"
