Worker Model OpenStack

CDS build using OVH.com OpenStack infrastructure

Create OpenStack user

In OVH manager, in cloud section, click on the menu on the Servers>OpenStack item.

You will be able to create a worker model OpenStack user, enter description (name and password will be generated).

Add OpenStack worker model

We need to define an OpenStack worker model to have OpenStack hatchery booting workers.

We will create a model called testopenstack:

You need to configure:

Via UI (inside settings section –> worker models):

For example:

Worker Model UI OpenStack

Or via CLI with a yaml file:

$ cds worker model import my_worker_model.yml
name: testopenstack
type: openstack
description: "my worker model"
group: shared.infra
image: "Debian 7"
flavor: vps-ssd-1
