Bundles Bundles Bundles!

You’ve gone through the process of sorting through various service orchestration solutions, and settled on Juju, since it will work with your existing frameworks and solutions, such as chef, puppet, and ansible. You’ve gone ahead and charmed up a few of your microservices so that you can get them deployed to your Juju environment. You’ve searched through the charmstore to find the databases, load balancers, and additional charms that you need to really make your project shine.

Whew! That’s gonna be a lot of docs to write for new hires, right?

Not necessarily! Here’s where bundles come into play!

Bundles allow you to pull all of your services, unit placements, and relations together into one YAML file. A bundle is basically an export of a Juju environment. In fact, if you use the Juju GUI, it literally is that: the GUI will export all of your services with all of their config values, all of the relations linking them together, and the way your units are placed on machines.
