Whats the status on juju annotations on juju 3.6+ ?

A year ago, we did some experiments with “annotations” for juju models, but at the time it was major issues for us using it.

  • Couldn’t interface with it from our libjuju codes.
  • Wasn’t well supported by the version of juju we used (~3.0)
  • Not documented

Q: What is the current status of “juju annotations” on juju (3.6+)

Q: What is the status on the support for annotations for use within lets say, libjuju (or similar which would allow us to use automation tools for working with it) ?

We would be greatly benefited from using a feature for this. Others has also mentioned it.

Is there any update on this?

Annotations were initially done in 2015 to record coordinates for use by the gui. As far as i recall, they’re only able to be set from within bundles, eg

applications:
  glance:
    annotations:
      gui-x: '250'
      gui-y: '0'
    charm: cs:glance
    num_units: 1

I’m not even sure there’s a cli command to inspect them. I think the feature is essentially orphaned since the old gui was dropped a while back and there’s no real cli for interacting with them.

There’s a client API for getting and setting them but as you say, I’m not sure libjuju supports it.

The doc as you say is very limited - there’s reference here with regard to diffing bundles https://documentation.ubuntu.com/juju/3.6/reference/juju-cli/list-of-juju-cli-commands/diff-bundle/

I imagine it would also be mentioned in the doc for specifying bundle content.

Given the above, I the utility of the annotations feature seems rather limited in its current form.
