Kubernetes Internal Management Network Planning
|
|
===============================================
|
|
|
|
The internal management network is a private network, visible only to the hosts
|
|
in the cluster.
|
|
|
|
.. note::
|
|
This network is not used with |prod| Simplex systems.
|
|
|
|
You must consider the following guidelines:
|
|
|
|
.. _internal-management-network-planning-ul-gqd-gj2-4n:
|
|
|
|
- The internal management network is used for |PXE| booting of new hosts, and
|
|
must be untagged. It is limited to IPv4, because the |prod| installer does
|
|
not support IPv6 |PXE| booting. For example, if the internal management
|
|
network needs to be on a |VLAN|-tagged network for deployment reasons, or
|
|
if it must support IPv6, you can configure the optional untagged |PXE| boot
|
|
network for |PXE| booting of new hosts using IPv4.
|
|
|
|
- You can use any 1 GB or 10 GB interface on the hosts to connect to this
|
|
network, provided that the interface supports network booting and can be
|
|
configured from the BIOS as the primary boot device.
|
|
|
|
- If static IP address assignment is used, you must use the :command:`system
|
|
host-add` command to add new hosts, and to assign IP addresses manually. In
|
|
this mode, new hosts are *not* automatically added to the inventory when
|
|
they are powered on, and they display the following message on the host
|
|
console:
|
|
|
|
.. code-block:: none
|
|
|
|
This system has been configured with static management
|
|
and infrastructure IP address allocation. This requires
|
|
that the node be manually provisioned in System
|
|
Inventory using the 'system host-add' CLI, GUI, or
|
|
stx API equivalent.
|
|
|
|
- For the IPv4 address plan, use a private IPv4 subnet as specified in RFC
|
|
1918. This helps prevent unwanted cross-network traffic on this network.
|
|
|
|
It is suggested that you use the default subnet and addresses provided by
|
|
the controller configuration script.
|
|
|
|
- You can assign a range of addresses on the management subnet for use by the
|
|
|prod|. If you do not assign a range, |prod| takes ownership of all
|
|
available addresses.
|
|
|
|
- On systems with two controllers, they use IP multicast messaging on the
|
|
internal management network. To prevent loss of controller synchronization,
|
|
ensure that the switches and other devices on these networks are configured
|
|
with appropriate settings.
