Juju-Info Interface

The juju info interface is a special and implicit relationship that works with subordinate charms. When building from layers, if your subordinate uses this interface, you will implicitly receive private-address.

There is no provides or peering mechanism on this interface.

States

{{relation-name}}.available

{{relation-name}}.connected

Both states signify the subordinate is successfully connected to the parent "container".

Note: these states key off of what the charm author names the relationship which should not be the name of the interface:

An example of a properly implemented relationship would resemble the following:

requires:
  host-system:
    interface: juju-info

The respective states in your charm would then be:

@when_any('host-system.available', 'host-system.connected')
