@sureshdsk I was testing this out and got the following error after running cat job.yaml.jinja2 | render_template > jobs.yaml

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'jinja2'

Were you able to test it out following the written instructions?

[sureshdsk]

@RinkiyaKeDad I've tried this out and its working correctly.
we need to have jinja2 package installed. Since it was not mentioned there already, I skipped that part.

command to install jinja2

pip install Jinja2 
or
pip3 install Jinja2

[RinkiyaKeDad]

I think we could add a note about that too since it might not be obvious to someone not familiar with python 🤔

[sureshdsk]

my bad. It is mentioned in before-you-begin section ->
