+# Ch06 lab
+
+Run the app:
+
+```
+kubectl apply -f lab/numbers/
+```
+
+Get the URL to browse to:
+
+```
+kubectl get svc numbers-web -o jsonpath='http://{.status.loadBalancer.ingress[0].*}:8086'
+```
+
+> Browse and try to get a random number, the app fails.
+
+## Sample Solution
+
+Add the RNG label to a node:
+
+```
+kubectl label node $(kubectl get nodes -o jsonpath='{.items[0].metadata.name}') rng=hw
+```
+
+Deploy the new resources - a [Deployment](solution/web-deployment.yaml) for the web app and a [DaemonSet](solution/api-daemonset.yaml) for the API:
+
+```
+kubectl apply -f lab/solution/
+```
+
+> Refresh the browser and confirm you can get a random number.
+
+Delete the old resources by their labels:
+
+```
+kubectl get all -l kiamol=ch06-lab
+
+kubectl delete all -l kiamol=ch06-lab
+```
