Scenario - Using the networking-calico Neutron plugin

Introduction

This document describes the steps required to deploy Project Calico Neutron networking with OpenStack-Ansible (OSA). These steps include:

Configure OSA environment overrides.
Configure OSA user variables.
Execute the playbooks.

For additional configuration about Project Calico and its architecture, please reference the networking-calico and Project Calico documentation.

Prerequisites

The deployment environment has been configured according to OSA best-practices. This includes cloning OSA software and bootstrapping Ansible. See OpenStack-Ansible Install Guide
BGP peers configured to accept routing announcements from your hypervisors. By default, the hypervisor's default router is set as the BGP peer.

Configure OSA Environment for Project Calico

Copy the etcd container definition to /etc/openstack_deploy/env.d/etcd.yml to enable the creation of the etcd cluster.

component_skel:
  etcd:
    belongs_to:
      - etcd_all
container_skel:
  etcd_container:
    belongs_to:
      - infra_containers
      - shared-infra_containers
    contains:
      - etcd
    properties:
      service_name: etcd

Copy the neutron environment overrides to /etc/openstack_deploy/env.d/neutron.yml to disable the creation of the neutron agents container, and implement the calico-dhcp-agent hosts group containing all compute hosts.

component_skel:
  neutron_calico_dhcp_agent:
    belongs_to:
    - neutron_all

container_skel:
  neutron_agents_container:
    contains: {}
  neutron_calico_dhcp_agent_container:
    belongs_to:
      - compute_containers
    contains:
      - neutron_calico_dhcp_agent
    properties:
      is_metal: true
      service_name: neutron

Configure networking-calico Neutron Plugin

Set the following in /etc/openstack_deploy/user_variables.yml.

neutron_plugin_type: ml2.calico
nova_network_type: calico

Installation

After multi-node OpenStack cluster is configured as detailed above; start the OpenStack deployment as listed in the OpenStack-Ansible Install guide by running all playbooks in sequence on the deployment host
