ConsulCluster Provides and Requires module.
This library contains Provider and Requirer classes for consul-cluster interface.
The provider side updates relation data with the endpoints information required by consul agents running in client mode or consul users/clients.
The requirer side receives the endpoints via relation data. Example on how to use Requirer side using this library.
Import ConsulEndpointsRequirer in your charm, with the charm object and the
relation name:
- self
- "consul-cluster"
Two events are also available to respond to: - endpoints_changed - goneaway
A basic example showing the usage of this relation follows:
from charms.consul_k8s.v0.consul_cluster import (
ConsulEndpointsRequirer
)
class ConsulClientCharm(CharmBase):
def __init__(self, *args):
super().__init__(*args)
# ConsulCluster Requires
self.consul = ConsulEdnpointsRequirer(
self, "consul-cluster",
)
self.framework.observe(
self.consul.on.endpoints_changed,
self._on_consul_service_endpoints_changed
)
self.framework.observe(
self.consul.on.goneaway,
self._on_consul_service_goneaway
)
def _on_consul_service_endpoints_changed(self, event):
'''React to the Consul service endpoints changed event.
This event happens when consul-cluster relation is added to the
model and relation data is changed.
'''
# Do something with the endpoints provided by relation.
pass
def _on_consul_service_goneaway(self, event):
'''React to the ConsulService goneaway event.
This event happens when consul-cluster relation is removed.
'''
# ConsulService Relation has goneaway.
pass
