Mock CKA scenario-based practice test

You have two virtual machines, master-0 and worker-0; please complete the following mock scenarios.

Scenario 1

Deploy a new deployment, nginx, with the latest image of nginx for two replicas in a namespace called packt-app. The container is exposed on port 80. Create a service type of ClusterIP within the same namespace. Deploy a sandbox-nginx pod and make a call using curl to verify the connectivity to the nginx service.

Scenario 2

Expose the nginx deployment with the NodePort service type; the container is exposed on port 80. Use the test-nginx pod to make a call using curl to verify the connectivity to the nginx service.

Scenario 3

Make a call using wget or curl from the machine within the same network as that node, to verify the connectivity with the nginx NodePort service through the correct port.

Scenario 4

Use the sandbox-nginx pod and nslookup for the IP address of the nginx NodePort service. See what is returned...
