I added a debug msg to check this, and as you can see the quotes are rendered as it is:

time="2021-10-11T23:24:48Z" level=info msg="CA secret [crdb-cockroachdb-ca-secret] is found in ready state, skipping CA generation"
---> cron string is "*/2 * * * *"     ########### cronStr value has double quotes in it.
