- Revision Library version 0.1
Library for the sdcore_config relation.
This library contains the Requires and Provides classes for handling the sdcore_config
interface.
The purpose of this library is to relate charms claiming to be able to provide or consume the information to access the webui GRPC address for configuration purposes in SD-Core.
Getting Started
From a charm directory, fetch the library using charmcraft:
charmcraft fetch-lib charms.sdcore_webui_k8s.v0.sdcore_config
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 Webui information.
Example:
import logging
from ops.charm import CharmBase
from ops.main import main
from lib.charms.sdcore_webui_k8s.v0.sdcore_config import (
SdcoreConfigRequires,
WebuiBroken,
WebuiUrlAvailable,
)
logger = logging.getLogger(__name__)
class DummySdcoreConfigRequirerCharm(CharmBase):
def __init__(self, *args):
super().__init__(*args)
self.webui_requirer = SdcoreConfigRequires(
self, "sdcore_config"
)
self.framework.observe(
self.webui_requirer.on.webui_url_available,
self._on_webui_url_available
)
self.framework.observe(self.webui_requirer.on.webui_broken, self._on_webui_broken)
def _on_webui_url_available(self, event: WebuiUrlAvailable):
logging.info(f"Webui URL from the event: {event.webui_url}")
logging.info(f"Webui URL from the property: {self.webui_requirer.webui_url}")
def _on_webui_broken(self, event: WebuiBroken) -> None:
logging.info(f"Received {event}")
if __name__ == "__main__":
main(DummySdcoreConfigRequirerCharm)
Provider charm
The provider charm is the one providing the information about the Webui.
Example:
from ops.charm import CharmBase, RelationJoinedEvent
from ops.main import main
from lib.charms.sdcore_webui_k8s.v0.sdcore_config import SdcoreConfigProvides
class DummySdcoreConfigProviderCharm(CharmBase):
WEBUI_URL = "sdcore-webui-k8s:9876"
def __init__(self, *args):
super().__init__(*args)
self.webui_url_provider = SdcoreConfigProvides(self, "sdcore_config")
self.framework.observe(
self.on.sdcore_config_relation_joined, self._on_sdcore_config_relation_joined
)
def _on_sdcore_config_relation_joined(self, event: RelationJoinedEvent):
relation_id = event.relation.id
self.webui_url_provider.set_webui_url(
webui_url=self.WEBUI_URL,
relation_id=relation_id,
)
if __name__ == "__main__":
main(DummySdcoreConfigProviderCharm)
