I believe that network-get should always return information for the cluster binding, even if not binding has been provided by the end-user of the charm. Otherwise we're back to 'unit-get private-address' which is know to be non-deterministic.

Raising juju task and marking rabbitmq charm bug as Invalid.

[John A Meinel (jameinel)]

Assuming this is about:
2017-05-16 19:01:30 INFO config-changed ERROR no network config found for binding "cluster"

I believe the comment that "juju deploy openstack-novalxd" should still provide a value for 'network-get ENDPOINT', even though no bindings were specified is valid.

We *should* have bindings for all endpoints, even if a user doesn't supply them. Ultimately there is supposed to be a model-level default binding for everything that is deployed without other arguments. I'm not 100% sure if without that configuration we'll get sane results, because we'll have machines deployed that don't have any constraints, meaning they could be in just about any spaces, and then what are we doing with the units that show up.

The *right* fix is that 'juju bootstrap' enforces a model-level default binding, which then every 'juju deploy' from then on uses the default binding if not otherwise specified.
In the short term, maybe we can use the "" space to give some sort of result for network-get.

[John A Meinel (jameinel)]

I know Witold recently made some changes wrt this which also should make 'unit-get private-address' more stable (albeit in the presence of bindings).
We should see if his changes in 2.2 also stabilize and give a value for 'network-get' when there are no explicit bindings.

[SysXpert (sysxpert)]

I am seeing this too. Is anyone going to do anything about it ?

[SysXpert (sysxpert)]

Any workarounds ?

[John A Meinel (jameinel)]

Is this being seen after an upgrade (of either juju or of a charm)?

The standard behavior for juju is to provide a binding definition for everything the charm exposes, though there is work that need to be done to allow users to update configurations post-deploy.
