yatinkarel 859f2ec917 Configure network for multiple-nics-vlans

Currently network config for external network
is not handled when deploying overcloud with
multiple-nics-vlans network_isolation.

This patch handles this case and configures the vlan
on external interface on the undercloud.

Role Name

An Ansible role to copy configuration files to the undercloud prior to deployment.

Requirements

This playbook expects that the undercloud has been installed and setup using one of the roles relevant to baremetal overcloud deployments.

Role Variables

Note: Make sure to include all environment file and options from your initial Overcloud creation.

working_dir: <'/home/stack'> -- working directory for the role. Assumes stackrc file is present at this location
baremetal_instackenv: <"{{ working_dir }}/instackenv.json"> -- location of instackenv.json to copy over
baremetal_network_environment: <"{{ working_dir }}/network-isolation.yml"> -- location of network-environment file to copy over
undercloud_type: -- can be overwritten with values like 'baremetal' or 'ovb'

undercloud_networks: by default an external network is defined by tripleo-quickstart, as follows:

undercloud_networks:
  external:
    address: "{{ undercloud_external_network_cidr|nthhost(1) }}"
    netmask: "{{ undercloud_external_network_cidr|ipaddr('netmask') }}"
    address6: "{{ undercloud_external_network_cidr6|nthhost(1) }}"
    device_type: ovs
    type: OVSIntPort
    ovs_bridge: br-ctlplane
    ovs_options: '"tag=10"'
    tag: 10

But it is possible to override this, when specific vlan options are needed:

undercloud_networks:
  external:
    address: 172.20.0.254
    netmask: 255.255.255.0
    device_type: ovs
    type: OVSIntPort
    ovs_bridge: br-ctlplane
    ovs_options: '"tag=1005"'
    tag: 1005

Or when the external network on the undercloud is and ethernet device instead of a bridge:

undercloud_networks:
  external:
    address: 172.20.0.254
    netmask: 255.255.255.0
    device_type: ethernet
    device_name: eth2

What makes the difference in this case is the device_type set to ethernet instead of ovs and the device_name which must be the name of the ethernet device on the undercloud.

Dependencies

This playbook does not deploy the overcloud. After this playbook runs, call https://github.com/redhat-openstack/ansible-role-tripleo-overcloud.
