Overview

OVN provides open source network virtualization for Open vSwitch (OVS).

Subordinate charm that deploys the networking-ovn component on neutron-api units and augments Neutron's configuration for use with the OVN ML2 plugin.

Note

: The OVN charms are considered preview charms.

Usage

OVN makes use of Public Key Infrastructure (PKI) to authenticate and authorize control plane communication. The charm requires a Certificate Authority to be present in the model as represented by the certificates relation.

There is an OVN overlay bundle for use in conjunction with the OpenStack Base bundle which give an example of how you can automate certificate lifecycle management with the help from Vault.

To deploy (partial deployment of linked charms only):

juju config neutron-api manage-neutron-plugin-legacy-mode=false

juju deploy neutron-api-plugin-ovn
juju deploy ovn-central -n 3 --config source=cloud:bionic-train
juju deploy ovn-chassis

juju add-relation neutron-api-plugin-ovn:certificates vault:certificates
