Challenge

Run a Job on a Schedule

In the one Namespace, run a Job that executes repeatedly on a schedule. Use a CronJob called pwd-runner to do this.

The Job should run the pwd command once every minute. Use the busybox:stable image. If the command takes longer than 10 seconds to execute, it should be automatically terminated.

Verify that the Job runs successfully at least once.
Challenge

Create a Deployment

Create a Deployment called nginx-dep in the two Namespace.

Use the nginx:stable image, and run with 3 replicas. Expose port 8081, and add an environment variable to the containers called NGINX_PORT with the value 8081. This will cause the nginx container to listen on port 8081.
