2020 Code Challenges

Problem #1 (Kubernetes)

We will be using kubernetes to manage our containers, and we need to know how basic kubernetes objects work, and how to provision them.

Challenge

Write the k8 config required to deploy a basic nginx webserver with this image nginxdemos/hello, using minikube to provision your cluster control plane.

Your resulting created objects should look similar to the likes of the below:

NAME                                     READY   STATUS    RESTARTS   AGE
pod/nginx-hello-world-84c67f76c4-4g5sd   1/1     Running   0          6s
