Lab 0: Preparation

1. Open a Terminal window by clicking on the Termnial icon in the left sidebar - we will use this extensively later as well

2. Start the demo application

   kubectl create -f ~/training/deployment/demoapp.yaml
   kubectl create -f ~/training/deployment/demoapp-service.yaml
   kubectl create -f ~/training/deployment/demoapp-backend.yaml
   kubectl create -f ~/training/deployment/demoapp-backend-service.yaml
   

   ``

3. Wait for the demo application to be available (the status must be 1/1)

   kubectl get pods
      
   > NAME                               READY   STATUS    RESTARTS   AGE
   > k8sdemo-backend-5b779f567f-2rbgj   1/1     Running   0          21s
   > k8sdemo-backend-5b779f567f-p6j76   1/1     Running   0          21s
   > k8sdemo-bd6bbd548-jcb6r            1/1     Running   0          21s
      
   

   ``

4. Open the demo application in the browser

   Training VM

   If you are using the training VM, you can open the webpage directly by typing:

   minikube service k8sdemo-service
   

   where k8sdemo-service is the name of the exposed kubernetes service.

   ---

   Cloud/Standalone

   If you are NOT using the training VM, you can open the webpage by typing:

   kubectl port-forward --namespace default $(kubectl get po -n default -l app=k8sdemo | grep k8sdemo | \awk '{print $1;}') 3000:3000
   

   And then navigating to http://localhost:3000/ in your browser.
