Ever Never write yaml definitions from blank page. Knowing every parameters of 

# kubectl run

command is the key parameter of success for this exam.


You can create, expose deployment with 5 replicas with limits at one command. 
# kubectl run nginx --image=nginx --replicas=5 --limits='cpu=200m,memory=512Mi' --expose --port=80

If you need bare pod use:
# --restart='Never'


If you need cron job use 
# --schedule='*/10 * * * *' --restart='Never'

If you need more than capability of kubectl run use:
# --dry-run -oyaml > your_template.yaml

and start to edit.
