How to configure network integrations#

Note

Network integrations are currently only available for the OVN network.

Network integrations can be used to connect networks on the local Incus deployment to remote networks hosted on Incus or other platforms.

OVN interconnection#

At this time the only type of network integrations supported is OVN which makes use of OVN interconnection gateways to peer OVN networks together across multiple deployments.

For this to work one needs a working OVN interconnection setup with:

  • OVN interconnection NorthBound and SouthBound databases

  • Two or more OVN clusters with their availability-zone names set properly (name property)

  • All OVN clusters need to have the ovn-ic daemon running

  • OVN clusters configured to advertise and learn routes from interconnection

  • At least one server marked as an OVN interconnection gateway

More details can be found in the upstream documentation.

Creating a network integration#

A network integration can be created with incus network integration create. Integrations are global to the Incus deployment, they are not tied to a network or project.

An example for an OVN integration would be:

incus network integration create ovn-region ovn
incus network integration set ovn-region ovn.northbound_connection tcp:[192.0.2.12]:6645,tcp:[192.0.3.13]:6645,tcp:[192.0.3.14]:6645
incus network integration set ovn-region ovn.southbound_connection tcp:[192.0.2.12]:6646,tcp:[192.0.3.13]:6646,tcp:[192.0.3.14]:6646

Using a network integration#

To make use of a network integration, one needs to peer with it.

This is done through incus network peer create, for example:

incus network peer create default region ovn-region --type=remote

Configuration options#

The following configuration options are available for all network integrations:

user.*

Free form user key/value storage

Key: user.*
Type:

string

User keys can be used in search.

OVN configuration options#

Those options are specific to the OVN network integrations:

ovn.ca_cert

OVN SSL certificate authority for the inter-connection database

Key: ovn.ca_cert
Type:

string

Scope:

global

ovn.client_cert

OVN SSL client certificate

Key: ovn.client_cert
Type:

string

Scope:

global

ovn.client_key

OVN SSL client key

Key: ovn.client_key
Type:

string

Scope:

global

ovn.northbound_connection

OVN northbound inter-connection connection string

Key: ovn.northbound_connection
Type:

string

Scope:

global

ovn.southbound_connection

OVN southbound inter-connection connection string

Key: ovn.southbound_connection
Type:

string

Scope:

global

ovn.transit.pattern

Template for the transit switch name

Key: ovn.transit.pattern
Type:

string

Default:

ts-incus-{{ integrationName }}-{{ projectName }}-{{ networkname }}

Specify a Pongo2 template string that represents the transit switch name. This template gets access to the project name (projectName), integration name (integrationName) and network name (networkName).
