This helped me a lot. Thank you.

I just have a couple of corrections:

1. The kubectl commands for the chainlink pod use a pathname that is not there:

kubernetes/basic-request-model/node

should be

kubernetes/node

2. Can't copy-paste the sed commands because the quote char used is not the right one (should be ").

3. The persistentVolume did not work for me; I used hostPath instead in deployment.yaml for postgres.

4. Passwords should have more than 12 chars, with at least 3 uppercase chars and 3 numbers.
