qwebirc89498Hello everyone02:26
qwebirc89498I'm facing an issue when using kuryr-kubernetes with openstack02:27
qwebirc89498how to set the annotations for the kind: Service02:28
qwebirc89498apiVersion: v1 kind: Service metadata:   name: nginx-kuryr-service22   annotations:      openstack.org/kuryr-lbaas-spec: ?????02:29
qwebirc89498if we don't set the annotations for the kind: Service then we will have a KeyError02:33
qwebirc89498_get_lbaas_spec will try to get the needed info from the parameter service02:33
qwebirc89498 annotations = service['metadata']['annotations']             annotation = annotations[k_const.K8S_ANNOTATION_LBAAS_SPEC]02:33
qwebirc89498any ideas on this configuration?02:34

janonymousqwebirc89498: ^^06:22
qwebirc89498janonymous:  I debugged this issue found that we need to get annotation info from the Service metadata part here is the code06:24
qwebirc89498annotations = service['metadata']['annotations']             annotation = annotations[k_const.K8S_ANNOTATION_LBAAS_SPEC]06:24
qwebirc89498if it's not existed then will return None06:25
janonymousqwebirc89498: i am not sure of type NodePort is supported yet... also what is out put of `kubectl get services -o yaml` and `kubectl get pods -o yaml`06:28
janonymousivc_:^^06:28
qwebirc89498janonymous: i tried NodePort  LoadBalancer ClusterIP all failed due to get the annnotations from Service06:29

*** limao has quit IRC09:23
kzaitsev_wsqwebirc89498: yeah. it's the usual routine to disable it09:23
qwebirc89498ok , one more question , for now  we only supplyr clusterIp service type?09:24
kzaitsev_wskuryr-k8s uses lbaasv2 for services. kube-proxy uses iptables rules. the 2 do not behave well together =)09:25
*** pmannidi has quit IRC09:25
qwebirc89498ok got it09:26
qwebirc89498do we have any doc about how to use the lbaasv2 for services?09:26
kzaitsev_wsyep. https://github.com/openstack/kuryr-kubernetes/blob/master/kuryr_kubernetes/controller/handlers/lbaas.py#L5309:27
kzaitsev_wsI don't think there's any specific doc on the topic though09:29
qwebirc89498ok09:29
qwebirc89498let me paste some info to describe my issue09:30
kzaitsev_wsI mean the regular install docs mention service_subnet =)09:30
qwebirc89498here is the debug info i got from the service parameter   http://paste.openstack.org/show/611475/09:35
qwebirc89498we can see that there in annotations in metadata part so in kuryr-kurbernetes will return None and eventually failed to create LB09:36
qwebirc89498sorry there is no annotation in the metadata part09:36
kzaitsev_wsI'm confused =)09:37
kzaitsev_wsI mean I don't understand your question =)09:38
*** garyloug has quit IRC09:40
qwebirc89498ok in another way when kuryr-kubernetes try to create LB for service , it need to get annotations info from the service object09:42
qwebirc89498 def on_present(self, service):         lbaas_spec = self._get_lbaas_spec(service)09:42
kzaitsev_wsI don't think it get's any annotations from service object09:42
kzaitsev_wsit watches for service object events09:43
kzaitsev_wsand if there is an event - sets the annotation itself09:43
*** garyloug has joined #openstack-kuryr09:43
kzaitsev_wswell, yes in a sense it gets annotation from the service object, but it was the annotation that kuryr-k8s has set itself earlier09:44
qwebirc89498inside of _get_lbaas_spec(service) func    there is part of code annotations = service['metadata']['annotations']             annotation = annotations[k_const.K8S_ANNOTATION_LBAAS_SPEC]09:44
qwebirc89498correct09:44
kzaitsev_wsqwebirc89498: well nobody expects you to put that annotation there by hand =)09:45
qwebirc89498so here the question is that how to prepare the yaml file to contains the annotations info ?09:45
kzaitsev_wsyou dont =)09:45
kzaitsev_wskuryr-k8s sets the annotation itself when it sees a new/empty service09:47
qwebirc89498then who will do that ?  i created the service and deployment by the yaml file09:47
qwebirc89498here is my content of the yaml file09:48
kzaitsev_wsjust follow a few lines deeper into the code. if the annotation is empty kuryr-k8s sets it09:48
qwebirc89498could you please point the code to me ? i debugged this issue if there is no annotation  then will return None09:49
qwebirc89498you mean we can just put an empty annotation to the yaml file?09:50
kzaitsev_wshttps://github.com/openstack/kuryr-kubernetes/blob/master/kuryr_kubernetes/controller/handlers/lbaas.py#L112-L12009:51

kzaitsev_wshttps://github.com/openstack/kuryr-kubernetes/blob/master/kuryr_kubernetes/controller/handlers/lbaas.py#L47-L4909:51
kzaitsev_wsso if there is no annotation - the spec is empty. kuryr-k8s builds a new one. it has changes (differs) with the empty one and it sets/updates the annotation09:52
kzaitsev_wsqwebirc89498: I mean that you don't set the annotation by hand09:53
