Use get_attr on the server resource to resolve attribute value from the subnet(s) and pass it to the parameter 'ControlPlaneSubnetCidr' used in the THT/network/config/* templates. As the value is now resolved from resource attributes, this changes the default for 'ControlPlaneSubnetCidr' to '' as well as the comment that these value should be overriden in parameters_defaults. It also removes the parameter from network-environment templates. A conditinal is used in puppet/role.role.j2.yaml so that the parameter value is used whenever it is not '' (the default) to provide backwards compatibility in case the user set a different value (different from the one used in undercloud.conf) for this parameter in network-environment.yaml. When deploying a routed control plane the network config templates would previously need to be updated to carry 'ControlPlaneXSubnetCidr' parameter (in case the subnet mask is not the same for all the routed network leafs). With 8 Leafs in addition to the network local to the undercloud that is 8 parameters less to place in the configuration. By getting the value to pass from the server resource this change reduces the required nic-config template customisation (reduces the risk of user error).

It is no longer a requirement to provide the parameter:
|
|
``ControlPlaneSubnetCidr`` in the environment when deploying. Now
|
|
``get_attr`` on the server resource is used to resolve the value from the
|
|
``ctlplane`` subnet's ``cidr`` attribute. A conditional is used to
|
|
determine if the user provided the parameter in the environment. If the
|
|
user provided the parameter, the user provided value is used.
|
|
upgrade:
|
|
- |
|
|
Since the the ``ControlPlaneSubnetCidr`` can now be resolved from the
|
|
``ctlplane`` subnet(s) this parameter can be removed from the environment
|
|
(``network-environment.yaml``).
|
|
|
|
.. Note:: Prior to removing the parameter, ensure that the property of
|
|
the ``ctlplane`` subnet(s) is correct. In case it is not, update
|
|
``undercloud.conf`` with the correct configuration and re-run the
|
|
``openstack undercloud install`` command to ensure the property
|
|
is set correctly.
|
|
|
|
.. Note:: ``ControlPlaneSubnetCidr`` is now passed to the network config
|
|
template when the resource is created. Because of this the
|
|
parameter must be defined in the network config template, even if
|
|
it is not used.
