provides

This is the provides side of the interface layer, for use only by the OpenStack integration charm itself.

The flags that are set by the provides side of this interface are:

endpoint.{endpoint_name}.requested This flag is set when there is a new or updated request by a remote unit for OpenStack integration features. The OpenStack integration charm should then iterate over each request, perform whatever actions are necessary to satisfy those requests, and then mark them as complete.

OpenStackIntegrationProvides

OpenStackIntegrationProvides(endpoint_name, relation_ids=None)

Example usage:

from charms.reactive import when, endpoint_from_flag
from charms import layer

@when('endpoint.openstack.requests-pending')
def handle_requests():
    openstack = endpoint_from_flag('endpoint.openstack.requests-pending')
    for request in openstack.requests:
        request.set_credentials(layer.openstack.get_user_credentials())
    openstack.mark_completed()

all_requests
