Hi Jean-Philippe,
Thanks you for this reply.
If I understand correctly, I have 2 options:
1. I deploy ODL before deploying OSA. Then in the OSA config file
"/etc/openstack_deploy/user_variables.yml", I point to the ODL API IP
address. No other modification done to OSA roles or playbooks are
required.
Here OSA does not install ODL, but it only configures neutron to works
with ODL.
2. I add an extra "opendaylight" group following the documentation
(either static or dynamic inventory).
Here the OSA script will install ODL from scratch (with no other
modification done to OSA roles and playbooks) and will configures
neutron to works with ODL.
I have the feeling that the first solution is 'easier'. In fact I am not
sure that I fully understand what it takes to add a new custom inventory
group and links it to the ODL deployment scripts in OSA.
I do know how to use ansible (I have writen several roles and
playbooks), but I prefer to modify OSA as little as possible (because of
the release rate).
So if the 1st solution works, I will try it ! Maybe I can share the
result in this ML because they were people how was interested in.
Regards,

Hello,
We don't ship with an opendaylight group by default in the integrated
repo.
Two choices:
- You deploy opendaylight on the side, and you point to it by having a
user variable odl_ip for example.
- You add an extra group (where you want to have it!) using
openstack-ansible inventory system.
For this you can either follow the documentation for manipulating the
dynamic inventory, or you can ship your own static inventory to
complement the dynamic inventory.
For the former, you should read this [1].
For the latter, you can simply create an
/etc/openstack_deploy/inventory.ini file, like a regular ansible ini
inventory.
Hope it helps.

Hi Openstack community !
I have a question regarding Openstack Ansible (OSA) and one
deployement
scenario "Scenario - OpenDaylight and Open vSwitch" (link below).
https://docs.openstack.org/openstack-ansible-os_neutron/latest/app-opendaylight.html
This is a lab test and I take inspiration from "Test environment"
example :
https://docs.openstack.org/openstack-ansible/queens/user/test/example.html
First, I have already tried and achieve to use the "OSA Scenario -
Using
Open vSwitch" (link below), which was necessary to understand before
trying the ODL + OvS scenario.
https://docs.openstack.org/openstack-ansible-os_neutron/latest/app-openvswitch.html
This means I was able to deploy Openstack with OvS as network driver
and
I was able to instatiates VMs on tenant VxLAN network, test networks
between VMs, use floating IPs, etc..
Now I want to try the "Scenario - OpenDaylight and Open vSwitch"
scenario because I want to deploy my Openstack environnement with the
"networking-sfc" driver activated.
I understand that I must modify the config file
"/etc/openstack_deploy/user_variables.yml" like this :
```
# /etc/openstack_deploy/user_variables.yml
### Ensure the openvswitch kernel module is loaded
openstack_host_specific_kernel_modules:
- name: "openvswitch"
pattern: "CONFIG_OPENVSWITCH"
group: "network_hosts"
### Use OpenDaylight SDN Controller
neutron_plugin_type: "ml2.opendaylight"
odl_ip: "{{
hostvars[groups['opendaylight'][0]]['ansible_default_ipv4']['address']
}}"
neutron_opendaylight_conf_ini_overrides:
ml2_odl:
url: "http://{{ odl_ip }}:8180/controller/nb/v2/neutron"
username: <username>
password: <password>
neutron_plugin_base:
- router
- metering
-
networking_sfc.services.flowclassifier.plugin.FlowClassifierPlugin
- networking_sfc.services.sfc.plugin.SfcPlugin
```
But there are no information about the
"/etc/openstack_deploy/openstack_user_config.yml" config file.
I am not sure if I understand where ansible get the value of "{{
odl_ip
}}" and "{{ hostvars[group....
In the file "/opt/openstack-ansible/tests/test_inventory.py", I find
out
that there is an entry for "opendaylight" in the
class TestAnsibleInventoryFormatConstraints(unittest.TestCase).
I assumed I must modify
"/etc/openstack_deploy/openstack_user_config.yml" like this :
```
# /etc/openstack_deploy/openstack_user_config.yml
[...]
# horizon
dashboard_hosts:
infra41:
ip: infra41.dom4.net
# neutron server, agents (L3, etc)
network_hosts:
network41:
ip: network41.dom4.net
opendaylight:
network41:
ip: network41.dom4.net
[...]
```
I have an infra node (with most of Openstack core services) and a
network node (dedicated to neutron). On my first try, I wanted to
install ODL on the network node (because I thought it will be deployed
in a LXC container). But I can dedicate an host to ODL if needed.
Could someone gives me some hints on this ? My goal is to deploy my
Openstack environnement with the "networking-sfc" driver, and using
OSA.
Maybe there are other method like "kolla-ansible", but I found that
OSA
has a more dense documentation.
Thanks you for your time.
