Lab 4.2 - Deploy the Cafe Application

1. Go back to the Web Shell session you opened in the previous task. If you need to open a new session go back to the Deployment tab of your UDF lab session at https://udf.f5.com to connect to kube-master1 using the Web Shell access method, then switch to the ubuntu user account using the “su” command:

   

   su ubuntu
   

2. Create the coffee and tea deployments and services

   kubectl create -f cafe-example/cafe.yaml
   

3. Create a secret with an SSL CERT and KEY for the Cafe app

   kubectl create -f cafe-example/cafe-secret.yaml
   

4. Create the Ingress resource

   kubectl create -f cafe-example/cafe-ingress.yaml
   

Test the Application

Now let’s test access to the new web application “through”” Firefox on superjump.

1. Go back to the Firefox session you opened in a previous task. If you need to open a new session, browse back to the Deployment tab of your UDF lab session at https://udf.f5.com and connect to superjump using the Firefox access method.

   Note

   The web application is not directly accessible from the public Internet. But since the superjump system is connected to the same internal virtual lab network we can use the Firefox access method because it provides browser-in-a-browser functionality that allows remote browsing to this new private web site.

   

2. Open a new tab an browse to one of the following URL’s:

   • https://cafe.example.com/tea
   • https://cafe.example.com/coffee

   Note

   If prompted with an SSL certificate warning be sure to accept the risk and continue.

   You should see something similar to the following:

   

   Attention

   Server address: The application pod IP

   Remote addr: The NGINX Ingress IP

   X-Real-IP: The client IP making the request

3. Before starting the next class run the following commands to clean-up the BIG-IP and exit the session from kube-master1.

   kubectl delete -f ingresslink/vs-ingresslink.yaml
   kubectl delete -f ingresslink/ingresslink-deployment.yaml
   

Attention

This is a CRITICAL step if you’re moving on to the next lab.

Attention

This concludes Class 1 - CIS and Kubernetes. Feel free to experiment with any of the settings. The lab will be destroyed at the end of the class/day.
