Q:  Create a job that calculates pi to 2000 decimal points using the container with the image named perl
and the following commands issued to the container:  ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"]
Once the job has completed, check the logs to and export the result to pi-result.txt.

Solution:

kc job pi2000 --image=perl -o yaml --dry-run > pi2000.yaml

### edit the file, edit the name, remove any ID references and include the command argument under container spec.
