Overview

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

The neutron-api-plugin-ovn charm is a subordinate charm that augments Neutron's configuration for use with the OVN ML2 driver. On OpenStack Ussuri and onwards the OVN ML2 driver is maintained as an in-tree driver in Neutron. On OpenStack Train it is maintained separately as the networking-ovn plugin.

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.

The OpenStack Base bundle gives an example of how you can deploy OpenStack and OVN with Vault to automate certificate lifecycle management.

Please refer to the OVN Appendix in the OpenStack Charms Deployment Guide for details.

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
juju add-relation neutron-api-plugin-ovn:neutron-plugin \
    neutron-api:neutron-plugin-api-subordinate
juju add-relation ovn-central:certificates vault:certificates
juju add-relation ovn-chassis:ovsdb ovn-central:ovsdb
juju add-relation ovn-chassis:certificates vault:certificates
