Nbi library.
This library implements both sides of the
nbi interface.
The provider side of this interface is implemented by the osm-nbi Charmed Operator.
Any Charmed Operator that requires NBI for providing its service should implement the requirer side of this interface.
In a nutshell using this library to implement a Charmed Operator requiring NBI would look like
$ charmcraft fetch-lib charms.osm_nbi.v0.nbi
metadata.yaml:
requires:
nbi:
interface: nbi
limit: 1
src/charm.py:
from charms.osm_nbi.v0.nbi import NbiRequires
from ops.charm import CharmBase
class MyCharm(CharmBase):
def __init__(self, *args):
super().__init__(*args)
self.nbi = NbiRequires(self)
self.framework.observe(
self.on["nbi"].relation_changed,
self._on_nbi_relation_changed,
)
self.framework.observe(
self.on["nbi"].relation_broken,
self._on_nbi_relation_broken,
)
self.framework.observe(
self.on["nbi"].relation_broken,
self._on_nbi_broken,
)
def _on_nbi_relation_broken(self, event):
# Get NBI host and port
host: str = self.nbi.host
port: int = self.nbi.port
# host => "osm-nbi"
# port => 9999
def _on_nbi_broken(self, event):
# Stop service
# ...
self.unit.status = BlockedStatus("need nbi relation")
