Dragonflow Manual Deployment
|
|
============================
|
|
|
|
Dragonflow mainly has several components:
|
|
|
|
#. Dragonflow neutron plugins (set up in neutron-server configuration)
|
|
#. Dragonflow local controller running on each compute node
|
|
#. Dragonflow metadata service running on each compute node
|
|
#. Dragonflow publisher service running aside neutron server (if zeromq pub/sub driver is enabled)
|
|
#. Dragonflow l3 agent running on each network node
|
|
#. Dragonflow northbound database (depends on which database you set up in dragonflow configuration)
|
|
|
|
Source Code

|
|
|
|
Dependencies
|
|
------------
|
|
|
|
#. Open vSwitch 2.5+
|
|
#. Northbound Database (Etcd or Zookeeper or Redis)
|
|
|
|
Basic Configurations
|
|
--------------------
|
|
|
|
#. Generate the plugin configuration
|
|
|

|
|
cp etc/dragonflow.ini.sample /etc/neutron/dragonflow.ini
|
|
|
|
#. Modify the configuration

|
Northbound Database
|
|
-------------------
|
|
|
|
Dragonflow supports etcd, redis, zookeeper and ramcloud. You need to deploy one of them
|
|
in your environment and expose the necessary TCP port.
|
|
|
|
Next you need to change the configuration, for example, etcd:
|
|
|
|
/etc/neutron/dragonflow.ini:
|
|
|
|
::
|
|
|
|
[df]
|
|
nb_db_class = etcd_nb_db_driver
|
|
remote_db_hosts = [{etcd_ip}:{etcd_port}]
|
|
|
|
Pub/Sub Driver
|
|
--------------
|
|
|
|
Dragonflow supports etcd, redis and zeromq. You need to change the configuration, for example, etcd:
|
|
|
|
/etc/neutron/dragonflow.ini:
|
|
|
|
::
|
|
|
|
[df]
|
|
enable_df_pub_sub = True
|
|
pub_sub_driver = etcd_pubsub_driver
|
|
publisher_rate_limit_count = 1
|
|
publisher_rate_limit_timeout = 180
|
|
monitor_table_poll_time = 30
|
|
|
|
