Re: 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: 
maintainer: OMMITED
description: |
  
tags:
  - misc
subordinate: false
provides:
  principal:
interface: principal


And a subordinate:
metadata.yaml:
name: charm-supordinate
summary: 
maintainer: OMMITED
description: |
  
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

Re: Subordinate charms

Hi Bilal,

I think that is not possible. When I try, I receive this: "You may not
remove a subordinate relation."

Re: Subordinate charms

[André Moreira]

Using this, it also removes the unit of the charm it is subordinated to.

Thank you, Mark, for the reply.
Nice to know there is this library and there will be an official one!
But, if I want to use the REST api without the python library, where can I
find documentation for it?

Hi Adam,
What I mean is how do I construct the json requests and how should I expect
the json response to be provided. Do you know where do I find this kind of
documentation? I mean, is there a doc for it without needing to read the
source code?

Juju service commands or communitation protocol

[André Moreira]

Is there a REST API for juju or the only possible ways to communicate with
it are either by juju command-line or juju gui? A service can communicate
with juju main agent and, for instance, add a new unit or start another
service? What is the proper way to do this? Is it possible to a charm to
ask juju to start another machine, add instances of a service or destroy
instances? For instance, by doing something simular to the juju gui: how
juju gui performs the creation of machines? I´d like to have a service that
monitors other services and add instances to scale out, for instance.
