How to: Lab 5.1. Creating Pods
1. Create a Pod with `nginx:alpine` image and confirm creation
2. Review full details of the Pod in YAML form
3. Display details of the Pod in readable form and review the Node, IP, container start date/time and Events
4. List pods but only show resource names
5. Connect a shell to the Pod and confirm an application is exposed
   - By default, Nginx exposes applications on port 80
   - confirm exposed ports
6. Delete the Pod
7. Review the Pod spec
8. Have a look at the Kubernetes API to determine when pods were introduced

> Not all images expose their applications on port 80. Kubernetes doesn't have a native way to check ports exposed on running container, however, you can connect a shell to a Pod with `kubectl exec` and try one of `netstat -tulpn` or `ss -tulpn` in the container, if installed, to show open ports.
