# Juju Charms
This is a collection of Juju charms for use as a reference and in
deploying real services using juju. See Juju's home page for
more information.
https://juju.ubuntu.com
https://launchpad.net/charm
# Quick Start
First, you'll need juju. If its not available in your version of Ubuntu
you can use the PPA:
sudo add-apt-repository ppa:juju/stable
sudo apt-get update
sudo apt-get install juju-core
You can install charm-tools from the distro, stable ppa, or daily-builds
PPA.
sudo apt-get install charm-tools
Alternatively you can branch the project and run the tip of the code.
bzr branch lp:charm-tools
cd charm-tools
If you've branched locally, you'll need to add the `charm-tools/bin`
directory to your `$PATH`
export PATH="$(pwd):${PATH}"
# Directory structure
## bin
tools to help in building charms
## templates
templates for usage in building new charms
# Tools
In order to use any of these charms, once you have juju setup and
working in your path
## create
To generate a new charm from a debian package available on your system
juju charm create foo
This should add a directory to charms with the name foo, and some of the
metadata.yml and hooks filled in. It will create these in $CHARM_HOME
or under the current working directory.
## proof
To perform basic static analysis on a charm, run
juju charm proof foo
It will analyze the charm for any obvious mistakes.
## getall
Retrieves all of the charms in the charm distribution via bzr.
## subscribers
This is used to check the quality of maintainer<->bug subscriptions in
launchpad since we do not have this relationship automatically setup.
As a maintainer, if you would like to ensure that you are subscribed to
all of your charms you can run this command:
juju charm subscribers --fix-unsubscribed --maintainer you@youremail.com --repository path/to/your/charms
