Installation guide for Dragonflow Keep in mind that Dragonflow is still in beta.
Prerequisites¶
- Open vSwitch 2.5.0
Quick Installation¶
Clone Devstack
git clone https://git.openstack.org/openstack-dev/devstackEdit local.conf according to your configuration, See Detailed Installation for more details, or the Devstack configuration manual
- Add the following lines in
local.conf:
Q_ENABLE_DRAGONFLOW_LOCAL_CONTROLLER=True
enable_plugin dragonflow https://github.com/openstack/dragonflow.git
enable_service df-controller
enable_service df-ext-services
enable_service df-l3-agent
enable_service q-svc
disable_service q-agt
disable_service n-net
DHCP configuration (IPv4 Only Environment):¶
no configuration needed
DHCP configuration (mixed IPv4/IPv6 or pure IPv6):¶
enable_service q-dhcp
If the q-dhcp is installed on a different Node from the q-svc
Please add the following flag to the neutron.conf on the q-svc node
use_centralized_ipv6_DHCP=True
Meta data and cloud init¶
In order to enable the VMs to get configuration like public keys, hostnames, etc.. you need to enable meta service. You can do it by adding the following lines to local.conf file (before running ‘stack.sh’ command):
enable_service q-meta enable_service q-dhcp
For the meta service to work correctly, another “hidden” service must be started. It is called meta-service-proxy and it is used to forward meta data client requests to real meta service. By default, it is started by regular q-dhcp service for each tenant. As a result ‘q-meta’ and ‘q-dhcp’ services must be enabled.
Database configuration:¶
Choose one of the following Database drivers in your local.conf
Etcd Database:
enable_service df-etcd
enable_service df-etcd-server
Ram Cloud Database:
enable_service df-ramcloud
enable_service df-rccoordinator
enable_service df-rcmaster
Zookeeper Database:
enable_service df-zookeeper
enable_service df-zookeeper-server
Redis Database:
enable_service df-redis
enable_service df-redis-server
Detailed Installation¶
Important parameters that needs to be set in local.conf :
HOST_IP <- The management IP address of the current node
FIXED_RANGE <- The overlay network address and mask
FIXED_NETWORK_SIZE <- Size of the overlay network
NETWORK_GATEWAY <- Default gateway for the overlay netowrk
FLOATING_RANGE <- Network address and range for Floating IP addresses (in the public network)
Q_FLOATING_ALLOCATION_POOL <- range to allow allocation of floating IP from (within FLOATING_RANGE)
PUBLIC_NETWORK_GATEWAY <- Default gateway for the public network
SERVICE_HOST <- Management IP address of the controller node
MYSQL_HOST <- Management IP address of the controller node
RABBIT_HOST <- Management IP address of the controller node
GLANCE_HOSTPORT <- Management IP address of the controller node (Leave the port as-is)
You can find example configuration files in the multi-node-conf or the single-node-conf directories.
