Roman Safronov 526693ed3c Remove ML2OVS-specific templates before migration to OVN
When running migration from ML2OVS to ML2OVN using infrared plugin
some ML2OVS-specific templates remain in 'overcloud deploy' command.
This is not correct and can cause issues.

Infrared plugin to carry out migration from ML2/OVS to OVN

This is an infrared plugin which can be used to carry out the migration from ML2/OVS to OVN if the tripleo was deployed using infrared. See http://infrared.readthedocs.io/en/stable/index.html for more information.

Before using this plugin, first deploy an ML2/OVS overcloud and then:

  1. On your undercloud, install python-neutron-ovn-migration-tool package (https://trunk.rdoproject.org/centos7-master/current/) You also need to install python-neutron and python3-openvswitch packages.
  2. Run :: $infrared plugin add "https://github.com/openstack/neutron.git"

3. Start migration by running:

$infrared  tripleo-ovn-migration  --version 13|14 \

--registry-namespace <REGISTRY_NAMESPACE> --registry-tag <TAG> --registry-prefix <PREFIX>

Using this as a standalone playbook for tripleo deployments

It is also possible to use the playbook main.yml with tripleo deployments. In order to use this:

1. Create hosts inventory file like below [undercloud] undercloud_ip ansible_ssh_user=stack

2. Run the playbook as: ansible-playbook main.yml -i hosts -e install_from_package=True -e registry_prefix=centos-binary -e registry_namespace=docker.io/tripleomaster -e registry_localnamespace=192.168.24.1:8787/tripleomaster -e registry_tag=current-tripleo-rdo
