Challenge

Create a Development Environment in the Cluster

Create a new Namespace called dev.

Deploy the app, including the backing service, to the dev Namespace.

You can find deployment descriptors for the frontend and backend in /home/cloud_user. Note that you may have to change the external ports used by NodePort Services for the dev Services to avoid port conflicts on the host. You can use ports 30082 and 30083 for this purpose.
Challenge

Retrieve Container Logs

Retrieve the container logs for the frontend container in the production Namespace and save them to a file at /home/cloud_user/production-frontend.log.
Challenge

Run the Admin Process

The frontend container image contains some code for an admin cleanup process. Use a Job called cleanup-job to run node cleanup.js using the linuxacademycontent/pirate-day:0.0.4 image. Run the Job in the production Namespace.
