Defining service-unit level relationships in charms

[Bruno Girin]

Denis,

You could do that by deploying individual services:

juju deploy ServiceA ServiceA-unit-1
juju deploy ServiceA ServiceA-unit-2
juju deploy ServiceA ServiceA-unit-3

juju deploy ServiceB ServiceB-unit-1
juju deploy ServiceB ServiceB-unit-2
juju deploy ServiceB ServiceB-unit-3

juju add-relation ServiceA-unit-1 ServiceB-unit1
juju add-relation ServiceA-unit-1 ServiceB-unit2
...

But of course that is very long-winded and not very scalable. Why do you
want to do this in the first place? There may be an easier way to
achieve the final goal than decomposing the unit relationship.

Cheers,

Bruno
