This is a recording of a masterclass that took place in January 2024 where Pietro Pasotti types you through writing from scratch a demo charm that deploys Nginx on a local lxd Juju controller and integrates with a tester charm to exchange ingress information.
Along the way, he explains the core concepts involved in the Juju model, and the terminology that one needs when working with charms. Lots of hands-on hackery involved.
