Chapter 3. Deploying an Overcloud with the Bare Metal Service

1. Configure the shell to access Identity as the administrative user:

   $ source ~/stackrc

2. Copy the network_data.yaml file:

   (undercloud) [stack@host01 ~]$ cp /usr/share/openstack-tripleo-heat-templates/network_data.yaml .

3. Edit the new network_data.yaml file and add a new network for IPv4 overcloud provisioning:

   # custom network for overcloud provisioning
   - name: OcProvisioning
   name_lower: oc_provisioning
   vip: true
   vlan: 205
   ip_subnet: '172.23.3.0/24'
   allocation_pools: [{'start': '172.23.3.10', 'end': '172.23.3.200'}]

4. Update the network_environments.yaml and nic-configs/controller.yaml files to use the new network.

   1. In the network_environments.yaml file, remap Ironic networks:

      ServiceNetMap:
         IronicApiNetwork: oc_provisioning
         IronicNetwork: oc_provisioning

   2. In the nic-configs/controller.yaml file, add an interface and necessary parameters:

      $network_config:
           - type: vlan
               vlan_id:
                 get_param: OcProvisioningNetworkVlanID
               addresses:
               - ip_netmask:
                   get_param: OcProvisioningIpSubnet

5. Copy the roles_data.yaml file:

   (undercloud) [stack@host01 ~]$ cp /usr/share/openstack-tripleo-heat-templates/roles_data.yaml .

6. Edit the new roles_data.yaml and add the new network for the controller:

     networks:
      ...
       OcProvisioning:
         subnet: oc_provisioning_subnet

7. Include the new network_data.yaml and roles_data.yaml files in the deploy command:

   -n /home/stack/network_data.yaml \
   -r /home/stack/roles_data.yaml \

Procedure

1. Configure the shell to access Identity as the administrative user:

   $ source ~/stackrc

2. Copy the network_data.yaml file:

   $ cp /usr/share/openstack-tripleo-heat-templates/network_data.yaml .

3. Edit the new network_data.yaml file and add a new network for overcloud provisioning:

   # custom network for IPv6 overcloud provisioning
   - name: OcProvisioningIPv6
   vip: true
   name_lower: oc_provisioning_ipv6
   vlan: 10
   ipv6: true
   ipv6_subnet: '$IPV6_SUBNET_ADDRESS/$IPV6_MASK'
   ipv6_allocation_pools: [{'start': '$IPV6_START_ADDRESS', 'end': '$IPV6_END_ADDRESS'}]
   gateway_ipv6: '$IPV6_GW_ADDRESS'

   • Replace $IPV6_ADDRESS with the IPv6 address of your IPv6 subnet.
   • Replace $IPV6_MASK with the IPv6 network mask for your IPv6 subnet.
   • Replace $IPV6_START_ADDRESS and $IPV6_END_ADDRESS with the IPv6 range that you want to use for address allocation.
   • Replace $IPV6_GW_ADDRESS with the IPv6 address of your gateway.

4. Create a new file network-environment.yaml and define IPv6 settings for the provisioning network:

   $ touch /home/stack/network-environment.yaml`

   1. Remap the ironic networks to use the new IPv6 provisioning network:

      ServiceNetMap:
         IronicApiNetwork: oc_provisioning_ipv6
         IronicNetwork: oc_provisioning_ipv6

   2. Set the IronicIpVersion parameter to 6:

      parameter_defaults:
        IronicIpVersion: 6

   3. Set the RabbitIPv6, MysqlIPv6, and RedisIPv6 parameters to True:

      parameter_defaults:
        RabbitIPv6: True
        MysqlIPv6: True
        RedisIPv6: True

   4. Set the ControlPlaneSubnetCidr parameter to the subnet IPv6 mask length for the provisioning network:

      parameter_defaults:
        ControlPlaneSubetCidr: '64'

   5. Set the ControlPlaneDefaultRoute parameter to the IPv6 address of the gateway router for the provisioning network:

      parameter_defaults:
        ControlPlaneDefaultRoute: <ipv6-address>

5. Add an interface and necessary parameters to the nic-configs/controller.yaml file:

   $network_config:
        - type: vlan
            vlan_id:
              get_param: OcProvisioningIPv6NetworkVlanID
            addresses:
            - ip_netmask:
                get_param: OcProvisioningIPv6IpSubnet

6. Copy the roles_data.yaml file:

   (undercloud) [stack@host01 ~]$ cp /usr/share/openstack-tripleo-heat-templates/roles_data.yaml .

7. Edit the new roles_data.yaml and add the new network for the controller:

     networks:
      ...
       - OcProvisioningIPv6
