Platform:

charms.sdcore_amf_k8s.v0.fiveg_n2

Library for the fiveg_n2 relation.

This library contains the Requires and Provides classes for handling the fiveg_n2 interface.

The purpose of this library is to relate a charm claiming to be able to provide or consume information on connectivity to the N2 plane.

Getting Started

From a charm directory, fetch the library using charmcraft:

charmcraft fetch-lib charms.sdcore_amf_k8s.v0.fiveg_n2

Add the following libraries to the charm's requirements.txt file:

  • pydantic
  • pytest-interface-tester
Requirer charm

The requirer charm is the one requiring the N2 information.

Example:


from ops.charm import CharmBase
from ops.main import main

from charms.sdcore_amf_k8s.v0.fiveg_n2 import N2InformationAvailableEvent, N2Requires

logger = logging.getLogger(__name__)


class DummyFivegN2Requires(CharmBase):

    def __init__(self, *args):
        super().__init__(*args)
        self.n2_requirer = N2Requires(self, "fiveg-n2")
        self.framework.observe(
            self.n2_requirer.on.n2_information_available, self._on_n2_information_available
        )

    def _on_n2_information_available(self, event: N2InformationAvailableEvent):
        amf_ip_address = event.amf_ip_address
        amf_hostname = event.amf_hostname
        amf_port = event.amf_port
        <do something with the amf IP, hostname and port>


if __name__ == "__main__":
    main(DummyFivegN2Requires)
Provider charm

The provider charm is the one providing the information about the N2 interface.

Example:


from ops.charm import CharmBase, RelationJoinedEvent
from ops.main import main

from charms.sdcore_amf_k8s.v0.fiveg_n2 import N2Provides


class DummyFivegN2ProviderCharm(CharmBase):

    HOST = "amf"
    PORT = 38412
    IP_ADDRESS = "192.168.70.132"

    def __init__(self, *args):
        super().__init__(*args)
        self.n2_provider = N2Provides(self, "fiveg-n2")
        self.framework.observe(
            self.on.fiveg_n2_relation_joined, self._on_fiveg_n2_relation_joined
        )

    def _on_fiveg_n2_relation_joined(self, event: RelationJoinedEvent):
        if self.unit.is_leader():
            self.n2_provider.set_n2_information(
                amf_ip_address=self.IP_ADDRESS,
                amf_hostname=self.HOST,
                amf_port=self.PORT,
            )


if __name__ == "__main__":
    main(DummyFivegN2ProviderCharm)
