Replacing extlookup to look up external things!

[Robert Inder]

I'm looking at the possibility of moving our Puppet manifests from 3.8 to Something More Recent (i.e. 6.1)

We have one big CSV file for (mostly) encrypted passwords and the like.

And our existing manifests use extlookup to extract the relevant entries, via calls like pw =

How should I replace this?

Can someone point me at an example of the simplest possible external lookup?

Robert.

Your simplest and most straightforward upgrade path would be to port the CSV file to a common.yaml file and then switch to using lookup() with hieradata. Later on, you can start differentiating and build a sane data hierarchy.

If you really must keep the CSV format, you can write your own function
that you use with hiera 5. It is quite simple. I show examples and
explain how hiera 5 works in this video:

You may want to watch that even if you convert your data to yaml.

Thanks, Ben.   That worked, and wasn't too painful.

Now all I have to do is get the mailalias module installing and working!

Thanks for the pointer.

I've gone down the convert-to-yaml route, but I'll look checkout

your video again once we've moved properly to Puppet 6.
