Dragonflow Manual Deployment

Dragonflow mainly has several components:

  1. Dragonflow neutron plugins (set up in neutron-server configuration)
  2. Dragonflow local controller running on each compute node
  3. Dragonflow metadata service running on each compute node
  4. Dragonflow publisher service running aside neutron server (if zeromq pub/sub driver is enabled)
  5. Dragonflow l3 agent running on each network node
  6. Dragonflow northbound database (depends on which database you set up in dragonflow configuration)

Dependencies

  1. Open vSwitch 2.5+
  2. Northbound Database (Etcd or Zookeeper or Redis)

Basic Configurations

  1. Generate the plugin configuration
bash tools/generate_config_file_samples.sh
cp etc/dragonflow.ini.sample /etc/neutron/dragonflow.ini
  1. Modify the configuration

/etc/neutron/neutron.conf

[DEFAULT]
metadata_proxy_shared_secret = secret
dhcp_agent_notification = False
notify_nova_on_port_data_changes = True
notify_nova_on_port_status_changes = True
allow_overlapping_ips = True
service_plugins = df-l3,qos
core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin

[qos]
notification_drivers = df_notification_driver

/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
tenant_network_types = geneve
extension_drivers = port_security,qos
mechanism_drivers = df

[ml2_type_flat]
flat_networks = *

[ml2_type_geneve]
vni_ranges = 1:10000

/etc/nova/nova.conf

[neutron]
service_metadata_proxy = True
metadata_proxy_shared_secret = secret

/etc/neutron/plugins/dragonflow.ini

[df]
metadata_interface = tap-metadata
enable_selective_topology_distribution = True
apps_list = l2_app.L2App,l3_proactive_app.L3ProactiveApp,dhcp_app.DHCPApp,dnat_app.DNATApp,sg_app.SGApp,portsec_app.PortSecApp,portqos_app.PortQosApp
integration_bridge = br-int
tunnel_type = geneve

[df_dnat_app]
ex_peer_patch_port = patch-int
int_peer_patch_port = patch-ex
external_network_bridge = br-ex

[df_l2_app]
l2_responder = True

[df_metadata]
port = 18080
ip = 169.254.169.254

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/plugins/dragonflow.ini:

[df]
nb_db_class = etcd_nb_db_driver
remote_db_port = {etcd_port}
remote_db_ip = {etcd_ip}

Pub/Sub Driver

Dragonflow supports zeromq and redis. You need to change the configuration, for example, zeromq:

/etc/neutron/plugins/dragonflow.ini:

[df]
enable_df_pub_sub = True
pub_sub_driver = zmq_pubsub_driver
publisher_multiproc_socket = /var/run/zmq_pubsub/zmq-publisher-socket
pub_sub_multiproc_driver = zmq_pubsub_multiproc_driver
pub_sub_use_multiproc = True
publisher_rate_limit_count = 1
publisher_rate_limit_timeout = 180
monitor_table_poll_time = 30

Dragonflow Plugin (on neutron-server node)

Installation

  1. Install dragonflow dependencies: pip install -r requirements.txt
  2. Install dragonflow: python setup.py install

Service Start

neutron-server is the only service for this part.

Dragonflow Publisher Service (on neutron-server node)

Installation

mkdir -p /var/run/zmq_pubsub
chown -R neutron:neutron /var/run/zmq_pubsub

Service Start

python /usr/local/bin/df-publisher-service --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/dragonflow.ini

Dragonflow local controller (on compute node)

Installation

  1. Install dragonflow dependencies: pip install -r requirements.txt

  2. Install dragonflow: python setup.py install

  3. Initialize ZeroMQ:

    mkdir -p /var/run/zmq_pubsub
chown -R neutron:neutron /var/run/zmq_pubsub

  4. Initialize OVS:

    ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex {external_nic}
ovs-vsctl add-br br-int
ovs-vsctl add-port br-int {internal_nic}
ovs-vsctl --no-wait set bridge br-int fail-mode=secure other-config:disable-in-band=true
ovs-vsctl set bridge br-int protocols=OpenFlow10,OpenFlow13
ovs-vsctl set-manager ptcp:6640:0.0.0.0

Configuration

/etc/neutron/dragonflow.ini:

[df]
local_ip = {compute_node_ip}

Service Start

python /usr/local/bin/df-local-controller --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/dragonflow.ini

Dragonflow Metadata Service (on compute node)

Service Start

python /usr/local/bin/df-metadata-service --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/dragonflow.ini

Dragonflow L3 Service (on network node)

Installation

  1. Install dragonflow dependencies: pip install -r requirements.txt
  2. Install dragonflow: python setup.py install

Configuration

/etc/neutron/l3_agent.ini:

[DEFAULT]
external_network_bridge =
