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.
