- Revision Library version 0.1
Library for the fiveg_nrf_k8s relation.
This library contains the Requires and Provides classes for handling the fiveg_nrf_k8s
interface.
The purpose of this library is to relate a charm claiming to provide NRF information and another charm requiring this information.
Getting Started
From a charm directory, fetch the library using charmcraft:
charmcraft fetch-lib charms.sdcore_nrf_k8s.v0.fiveg_nrf_k8s
Add the following libraries to the charm's requirements.txt file:
- pydantic
Requirer charm
The requirer charm is the one requiring the NRF information.
Example:
from ops.charm import CharmBase
from ops.main import main
from charms.sdcore_nrf_k8s.v0.fiveg_nrf_k8s import NRFAvailableEvent, NRFRequires
logger = logging.getLogger(__name__)
class DummyFiveGNRFRequirerCharm(CharmBase):
def __init__(self, *args):
super().__init__(*args)
self.nrf_requirer = NRFRequires(self, "fiveg-nrf")
self.framework.observe(self.nrf_requirer.on.nrf_available, self._on_nrf_available)
def _on_nrf_available(self, event: NRFAvailableEvent):
nrf_url = self.nrf_requirer.nrf_url
<do something with the nrf_url>
if __name__ == "__main__":
main(DummyFiveGNRFRequirerCharm)
Provider charm
The provider charm is the one providing the information about the NRF.
Example:
from ops.charm import CharmBase, RelationJoinedEvent
from ops.main import main
from charms.sdcore_nrf_k8s.v0.fiveg_nrf_k8s import NRFProvides
class DummyFiveGNRFProviderCharm(CharmBase):
NRF_URL = "https://nrf.example.com"
def __init__(self, *args):
super().__init__(*args)
self.nrf_provider = NRFProvides(self, "fiveg-nrf")
self.framework.observe(
self.on.fiveg_nrf_relation_joined, self._on_fiveg_nrf_relation_joined
)
def _on_fiveg_nrf_relation_joined(self, event: RelationJoinedEvent):
relation_id = event.relation.id
self.nrf_provider.set_nrf_information(
url=self.NRF_URL,
relation_id=relation_id,
)
def _on_nrf_url_changed(
self,
):
self.nrf_provider.set_nrf_information_in_all_relations(
url="https://different.nrf.com",
)
if __name__ == "__main__":
main(DummyFiveGNRFProviderCharm)
