provides

This is the provides side of the interface layer, for use only by the AWS integrator 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 AWS integration features. The AWS integration charm should then iterate over each request, perform whatever actions are necessary to satisfy those requests, and then mark them as complete.

AWSIntegrationProvides Objects

class AWSIntegrationProvides(Endpoint)

Example usage:

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

@when('endpoint.aws.requested')
def handle_requests():
    aws = endpoint_from_flag('endpoint.aws.requested')
    for request in aws.requests:
        if request.instance_tags:
            tag_instance(
                request.instance_id,
                request.region,
                request.instance_tags)
        if request.requested_load_balancer_management:
            layer.aws.enable_load_balancer_management(
                request.application_name,
                request.instance_id,
                request.region,
            )
        # ...
        request.mark_completed()
