Assumptions: the charm name is fluentd

Submitting a layered charm

Register an account on launchpad, if you don't already have one. You'll need the name later in the process.

Create a launchpad branch of the deployable charm

[~/charms/layers/fluentd] $ charm build

The Juju core team have been diligently ramping up to Juju 2.0. As a result they have been steadily releasing new alphas and betas of juju for testing and feedback. However, for some that's not quite fast enough! If you're looking to try out, or contribute to juju, odds are you're going to want to compile from source. This article aims to cover how to do this and manage all the versions of juju you have floating around your system - compiled versions of juju, stable version of juju, and the released development versions.
