Juju configuration in bash

[Marco Ceppi]

Hello!

Yes, you certainly can. In fact, the charmhelpers python library is just a
shim to make writing charms in python easier. In bash you'll want to do
something like the following:

option=$(config-get option)

This is, essentially what the charmhelpers library is doing under the
covers. There's a WIDE range of these hook tools you can use in your hooks,
for an exhaustive list run

juju help-tool

And to learn more how to use a tool, run

juju help-tool config-get

Thanks!
