`show-relation` fails on cross model relations with alias #178

Open Mehdi-Bendriss opened 2 months ago

Mehdi-Bendriss commented 2 months ago

On a cross model relation with an offer made with an alias, the show-relation sub-command is unable to resolve the app from both the "offerer" and the "consumer" models.

Model dev:

juju deploy opensearch main  
juju offer main:peer-cluster-orchestrator main-orchestrator

Model dev1:

juju deploy opensearch data
juju integrate data:peer-cluster admin/dev.main-orchestrator

Then from the model dev1:

jhack show-relation main-orchestrator:peer-cluster-orchestrator data:peer-cluster

===> KeyError: 'main-orchestrator'

or by specifying the model name:

jhack show-relation -m dev main-orchestrator:peer-cluster-orchestrator data:peer-cluster

===> RuntimeError: No relation found with endpoints 'main-orchestrator:peer-cluster-orchestrator' -> 'data:peer-cluster' in model 'dev'. 'data' not found in model 'dev'

jhack version: 0.4.3.1

I'm struggling to find the aliased app's data anywhere in juju show-unit. I suspect there's a bug in show-unit itself, which won't list any aliased SAAS. If that's the case, there's currently no way in juju to inspect aliased CMR data.

I will work around that with a super-nasty hack if this is confirmed
