How to validate OpenDaylight service?

Resolution

• To test that OpenDaylight is working, as a superuser login to the overcloud controller node running OpenDaylight or an OpenDaylight node running in a composable role.

• Verify that the OpenDaylight container service is active:

  @overcloud-controller-0 ~]# docker ps | grep opendaylight
  2363a99d514a        xxx.xx.x.1:8787/rhosp12/openstack-opendaylight:latest         "kolla_start"            4 hours ago         Up 4 hours (healthy)                       opendaylight_api
  

• Verify that HAProxy is properly configured to listen on port 8081:

  @overcloud-controller-0 ~]# docker exec -it -u root haproxy-bundle-docker-0 grep -A7 opendaylight /etc/haproxy/haproxy.cfg
  listen opendaylight
    bind xxx.xx.x.10:8081 transparent
    bind xxx.xx.x.10:8081 transparent
    mode http
    balance source
    server overcloud-controller-0.internalapi.localdomain xxx.xx.x.22:8081 check fall 5 inter 2000 rise 2
    server overcloud-controller-1.internalapi.localdomain xxx.xx.x.12:8081 check fall 5 inter 2000 rise 2
    server overcloud-controller-2.internalapi.localdomain xxx.xx.x.13:8081 check fall 5 inter 2000 rise 2
  

• From overcloud controller connect to the karaf account:

  ssh -p 8101 karaf@localhost
  

• List the installed features.

  opendaylight-user@root>feature:list -i

• Verify Netvirt features.

  opendaylight-user@root>feature:list -i | grep odl-netvirt-openstack
  odl-netvirt-openstack                          | 0.4.2.Carbon-redhat-3  | x         | odl-netvirt-0.4.2.Carbon-redhat-3                | OpenDaylight :: NetVirt :: OpenStack     
  

• Verify that the API is up and running.

  opendaylight-user@root>web:list | grep neutron
  280 | Active      | Deployed    | 80    | /controller/nb/v2/neutron | org.opendaylight.neutron.northbound-api (0.8.2.Carbon-redhat-3)
  

• Verify that VXLAN tunnels between the nodes are up.

  opendaylight-user@root>vxlan:show

• To test that the REST API is responding correctly, you can list the modules that are using it.

  @overcloud-controller-0 ~]# curl -u "admin:admin" http://$controller_local_InternalAPI_IP:8181/restconf/modules
  
  The output will be similar (the example has been shortened). 
  
  {"modules":{"module":[{"name":"netty-event-executor","revision":"2017-12-29","namespace":"urn:opendaylight:params:xml:ns:yang:controller:netty:eventexecutor"},{"name" ...
  

• List the REST streams.

  @overcloud-controller-0 ~]# curl -u "admin:admin" http://$controller_local_InternalAPI_IP:8181/restconf/streams
  
  You will get something like this: 
  
  {"streams":{}}
  

• Enter the following command to verify that NetVirt is ready and running.

  @overcloud-controller-0 ~]# curl -u "admin:admin" http://$controller_local_InternalAPI_IP:8181/restconf/operational/network-topology:network-topology/topology/netvirt:1
  
  The following output will confirm it. 
  
  {"topology":[{"topology-id":"netvirt:1"}]}
