CKAD exercises - Core Concepts - nodered, busybox and ubuntu docker on kubernetes.
The video will show how to solve these sample exercises:
1.- Create a new Pod named nodered running the image node-red:latest from nodered docker hub repo. Expose the container port 1880. The Pod should live in the namespace named ckad.
2.- Get the IP address of the nodered Pod.
3.- Create a temporary Pod that uses the busybox image to execute a wget command inside of the container. The wget command should access the endpoint exposed by the nodered container. You should see the HTML response body rendered in the terminal.
4.- Get the logs of the nodered container.
5.- Add the environment variables FLOWS=my_flows.json and TZ=Europe/Madrid to the container of the nodered Pod.
6.- Open a shell for the nodered container, inspect the contents of the current directory and its path.
7.- Create a YAML manifest for a Pod named loop that runs the ubuntu image in a container. The container should run the following command: for i in {1..20}; do echo "Welcome $i times"; done. Create the Pod from the YAML manifest.
8.- Edit the Pod named loop. Change the command to run in an endless loop. Each iteration should echo a message.
9.- Inspect the events and the status of the Pod loop.
10.- Delete all the pods created and the namespace ckad.
