I'm not sure about a recipe, but the the "kinit" man page trivially
explains how to get a password from a stashed location, and also
explains how to specifies how to set the lifetime of the requested
ticket.

So, you just run kinit in cron as the specified daemon user with the
appropriate flags and it will renew its own tickets and all is well.

I'm not sure why people think this is all so mysterious. Can you
explain what is hard about this?

Why bother when kinit will do the job? That's what it is for.
