[@raghurajeshpudi4315]

Yes

[@sethuramvenkatesh]

For the last question, I would choose my answer by asking further more questions Is it gonna be a 1 time requirement ? Or is it gonna be used for multiple environments? If yes, I would choose Helm charts thus ensuring DRY (Don't Repeat Yourself) principle. If no, given the time constraint to be 10 mins, I would go with regular deployments which otherwise would have been wasted in templatizing helm charts, which is clearly not the case here.

[@nagarajunagari4749]
