With support for routed networks, several options are deprecated and the
|
|
way undercloud networking is defined in the configuration file has several
|
|
changes. Please refer to the **Deprecation Notes** and **Upgrade notes**
|
|
section for details.
|
|
features:
|
|
- Routed networks support adds the ability to configure Ironic Inspector
|
|
and Neutron provisioning network in the undercloud to enable provisioning
|
|
of nodes via DHCP-relay to the undercloud from remote routed network
|
|
segments.
|
|
upgrade:
|
|
- |
|
|
With support for routed network segments, several options are deprecated
|
|
and the way undercloud networking is defined in the configuration file has
|
|
several changes.
|
|
|
|
**New option:** ``subnets`` A list of subnets. One entry for each routed
|
|
network segment used for provisioning and introspection. For each network
|
|
segment a section/group needs to be added to the configuration file
|
|
specifying the following subnet options:
|
|
|
|
====================== ================================================
|
|
option Description
|
|
====================== ================================================
|
|
``cidr`` Network CIDR for the subnet.
|
|
``dhcp_start`` Start of DHCP allocation range for PXE and DHCP.
|
|
``dhcp_end`` End of DHCP allocation range for PXE and DHCP.
|
|
``inspection_iprange`` Temporary IP range that will be given to nodes
|
|
during the inspection process.
|
|
``gateway`` Network(subnet) gateway/router.
|
|
``masquerade`` (Boolean) If ``True`` the undercloud will
|
|
masquerade this network for external access.
|
|
====================== ================================================
|
|
|
|
**New option:** ``local_subnet`` The name of the local subnet, where the
|
|
PXE boot and DHCP interfaces for overcloud instances is located. The IP
|
|
address of the local_ip/local_interface should reside in this subnet.
|
|
|
|
.. Note:: Upgrade with migration to routed networks support is not
|
|
possible.
|
|
|
|
Routed networks use the neutron segments service_plugin, this
|
|
plugin adds functionality that allows subnet to be associated
|
|
with a network segment. It is currently not possible to add
|
|
segment association to an existing subnet, because of this we
|
|
cannot add segment association to the existing ctlplane subnet
|
|
on the upgraded undercloud. The existing ctlplane network and
|
|
subnet will still be in place after an upgrade and the upgraded
|
|
undercloud can continue to manage the existing overcloud.
|
|
|
|
The following example shows what changes to make to the configuration to
|
|
move to the new model.
|
|
|
|
Replace usage of deprecated options::
|
|
|
|
[DEFAULT]
|
|
network_gateway = 192.168.24.1
|
|
network_cidr = 192.168.24.0/24
|
|
dhcp_start = 192.168.24.5
|
|
dhcp_end = 192.168.24.24
|
|
inspection_iprange = 192.168.24.100,192.168.24.120
|
|
masquerade_network = 192.168.24.0/24
|
|
|
|
replace with::
|
|
|
|
[DEFAULT]
|
|
subnets = subnet0
|
|
local_subnet = subnet0
|
|
|
|
[subnet0]
|
|
cidr = 192.168.24.0/24
|
|
dhcp_start = 192.168.24.5
|
|
dhcp_end = 192.168.24.24
|
|
inspection_iprange = 192.168.24.100,192.168.24.120
|
|
gateway = 192.168.24.1
|
|
masquerade = True
|
|
deprecations:
|
|
- With support for routed networks/subnets the ``network_gateway`` option in
|
|
the ``[DEFAULT]`` section is deprecated. Moved to per-subnet options
|
|
group.
|
|
- With support for routed networks/subnets the ``network_cidr`` option in
|
|
the ``[DEFAULT]`` section is deprecated. Moved to per-subnet options
|
|
group.
|
|
- With support for routed networks/subnets the ``dhcp_start`` and
|
|
``dhcp_end`` options in the ``[DEFAULT]`` section are deprecated. Moved to
|
|
per-subnet options group.
|
|
- With support for routed networks/subnets the ``inspection_iprange`` option
|
|
in the ``[DEFAULT]`` section is deprecated. Moved to per-subnet options
|
|
group.
|
|
- With support for routed networks/subnets the ``masquerade_network``
|
|
option in the ``[DEFAULT]`` section is deprecated. Use the boolean option
|
|
in each subnet group.
