Interface library for sharing hydra endpoints.
This library provides a Python API for both requesting and providing public and admin endpoints.
Getting Started
To get started using the library, you need to fetch the library using charmcraft.
cd some-charm
charmcraft fetch-lib charms.hydra.v0.hydra_endpoints
To use the library from the requirer side:
In the metadata.yaml of the charm, add the following:
requires:
hydra-endpoint-info:
interface: hydra_endpoints
limit: 1
Then, to initialise the library:
from charms.hydra.v0.hydra_endpoints import (
HydraEndpointsRelationError,
HydraEndpointsRequirer,
)
Class SomeCharm(CharmBase):
def __init__(self, *args):
self.hydra_endpoints_relation = HydraEndpointsRequirer(self)
self.framework.observe(self.on.some_event_emitted, self.some_event_function)
def some_event_function():
# fetch the relation info
try:
hydra_data = self.hydra_endpoints_relation.get_hydra_endpoints()
except HydraEndpointsRelationError as error:
...
