README

To play with this demo, you need to:

• Create a GKE cluster with version 1.8.7.

• Deploy the node agent as DaemonSet by

kubectl apply -f nodeagent.yaml

• Make sure the node agent is up and running

kubectl get pods

# Sample output
NAME                              READY     STATUS        RESTARTS   AGE
nodeagent-fs8lt                   1/1       Running       0          3m
nodeagent-qt6z6                   1/1       Running       0          3m

• Deploy the workload pod.

kubectl apply -f workload/workload.yaml

• Make sure the workload is up and running, and then check the log of node agent.

kubectl logs nodeagent-fs8lt

#Sample output
Node agent with both mgmt and workload api interfaces.

From the output above you can see node agent is able to get the workload's uid info when receives requests from it.
