Subordinate charms

[André Moreira]

José,

They are charms I created to deploy some services that I have.
I have a "principal" charm with something like this (I had to change the
actual names):

metadata.yaml:
name: charm-principal
summary: <Fill in summary here>
maintainer: OMMITED
description: |
  <Multi-line description here>
tags:
  - misc
subordinate: false
provides:
  principal:
    interface: principal


And a subordinate:
metadata.yaml:
name: charm-supordinate
summary: <Fill in summary here>
maintainer: OMMITED
description: |
  <Multi-line description here>
tags:
  - misc
subordinate: true
requires:
  principal:
    interface: principal
    scope: container

When I deploy both charms, as expected, only the "charm-principal" get a
unit. I cannot destroy the relation between them and, if I remove
"charm-subordinate", the unit of the principal charm is destroyed.

André

Le doux charme de maint songe
Par leur bel art inventé
Sous les habits du mensonge
Nous offre la vérité.
