Charm anatomy
- metadata.yaml
- config.yaml

- Can be written in anything (mostly Python though)
Example
juju init juju deploy myapp juju deploy postgres juju add-relation myapp postgres juju add-unit postgres -n 2 juju stat
Configuration
juju set myapp foo=bar juju set haproxy global_user=haproxy_admin
Best practice presets
juju set wordpress tuning=optimized
Not just configuration management..
- Use with your favourite CM (Ansible, Chef, Puppet etc.)
- CM handles machine configuration, can be mixed with service config
