Overview

~~~~~~~~
|
||
|
||
This example allows you to use your own parameters for the deployment.
|
||
|
||
The following is a table of the bridges that are be configured on hosts, if
|
||
you followed the previously proposed design.
|

+-------------+-----------------------+-------------------------------------+

Modifying the network interfaces file
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
After establishing initial host management network connectivity using
|
||
the ``bond0`` interface, modify the ``/etc/network/interfaces`` file as
|
||
described in the following procedure.
|
||
|
||
**Procedure 4.1. Modifying the network interfaces file**
|
||
|
||
#. Physical interfaces:
|
||
|
||
.. code-block:: yaml
|
||
|
||
# Physical interface 1
|
||
auto eth0
|
||
iface eth0 inet manual
|
||
bond-master bond0
|
||
bond-primary eth0
|
||
|
||
# Physical interface 2
|
||
auto eth1
|
||
iface eth1 inet manual
|
||
bond-master bond1
|
||
bond-primary eth1
|
||
|
||
# Physical interface 3
|
||
auto eth2
|
||
iface eth2 inet manual
|
||
bond-master bond0
|
||
|
||
# Physical interface 4
|
||
auto eth3
|
||
iface eth3 inet manual
|
||
bond-master bond1
|
||
|
||
#. Bonding interfaces:
|
||
|
||
.. code-block:: yaml
|
||
|
||
# Bond interface 0 (physical interfaces 1 and 3)
|
||
auto bond0
|
||
iface bond0 inet static
|
||
bond-slaves eth0 eth2
|
||
bond-mode active-backup
|
||
bond-miimon 100
|
||
bond-downdelay 200
|
||
bond-updelay 200
|
||
address HOST_IP_ADDRESS
|
||
netmask HOST_NETMASK
|
||
gateway HOST_GATEWAY
|
||
dns-nameservers HOST_DNS_SERVERS
|
||
|
||
# Bond interface 1 (physical interfaces 2 and 4)
|
||
auto bond1
|
||
iface bond1 inet manual
|
||
bond-slaves eth1 eth3
|
||
bond-mode active-backup
|
||
bond-miimon 100
|
||
bond-downdelay 250
|
||
bond-updelay 250
|
||
|
||
If not already complete, replace ``HOST_IP_ADDRESS``,
|
||
``HOST_NETMASK``, ``HOST_GATEWAY``, and ``HOST_DNS_SERVERS``
|
||
with the appropriate configuration for the host management network.
|
||
|
||
#. Logical (VLAN) interfaces:
|
||
|
||
.. code-block:: yaml
|
||
|
||
# Container management VLAN interface
|
||
iface bond0.CONTAINER_MGMT_VLAN_ID inet manual
|
||
vlan-raw-device bond0
|
||
|
||
# OpenStack Networking VXLAN (tunnel/overlay) VLAN interface
|
||
iface bond1.TUNNEL_VLAN_ID inet manual
|
||
vlan-raw-device bond1
|
||
|
||
# Storage network VLAN interface (optional)
|
||
iface bond0.STORAGE_VLAN_ID inet manual
|
||
vlan-raw-device bond0
|
||
|
||
Replace ``*_VLAN_ID`` with the appropriate configuration for the
|
||
environment.
|
||
|
||
#. Bridge devices:
|
||
|
||
.. code-block:: yaml
|
||
|
||
# Container management bridge
|
||
auto br-mgmt
|
||
iface br-mgmt inet static
|
||
bridge_stp off
|
||
bridge_waitport 0
|
||
bridge_fd 0
|
||
# Bridge port references tagged interface
|
||
bridge_ports bond0.CONTAINER_MGMT_VLAN_ID
|
||
address CONTAINER_MGMT_BRIDGE_IP_ADDRESS
|
||
netmask CONTAINER_MGMT_BRIDGE_NETMASK
|
||
dns-nameservers CONTAINER_MGMT_BRIDGE_DNS_SERVERS
|
||
|
||
# OpenStack Networking VXLAN (tunnel/overlay) bridge
|
||
auto br-vxlan
|
||
iface br-vxlan inet static
|
||
bridge_stp off
|
||
bridge_waitport 0
|
||
bridge_fd 0
|
||
# Bridge port references tagged interface
|
||
bridge_ports bond1.TUNNEL_VLAN_ID
|
||
address TUNNEL_BRIDGE_IP_ADDRESS
|
||
netmask TUNNEL_BRIDGE_NETMASK
|
||
|
||
# OpenStack Networking VLAN bridge
|
||
auto br-vlan
|
||
iface br-vlan inet manual
|
||
bridge_stp off
|
||
bridge_waitport 0
|
||
bridge_fd 0
|
||
# Bridge port references untagged interface
|
||
bridge_ports bond1
|
||
|
||
# Storage bridge (optional)
|
||
auto br-storage
|
||
iface br-storage inet static
|
||
bridge_stp off
|
||
bridge_waitport 0
|
||
bridge_fd 0
|
||
# Bridge port reference tagged interface
|
||
bridge_ports bond0.STORAGE_VLAN_ID
|
||
address STORAGE_BRIDGE_IP_ADDRESS
|
||
netmask STORAGE_BRIDGE_NETMASK
|
||
|
||
Replace ``*_VLAN_ID``, ``*_BRIDGE_IP_ADDRESS``, and
|
||
``*_BRIDGE_NETMASK``, ``*_BRIDGE_DNS_SERVERS`` with the
|
||
appropriate configuration for the environment.

Example for 3 controller nodes and 2 compute nodes
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||

|
||
|
||

|
||
- Container management: 10
|
||
- Tunnels: 30
|
||
- Storage: 20
|
||
|
||
- Networks:
|
||
|
||
- Host management: 10.240.0.0/22
|
||
- Container management: 172.29.236.0/22
|
||
- Tunnel: 172.29.240.0/22
|
||
- Storage: 172.29.244.0/22
|
||
|
||
- Addresses for the controller nodes:
|
||
|
||
- Host management: 10.240.0.11 - 10.240.0.13
|
||
- Host management gateway: 10.240.0.1
|
||
- DNS servers: 69.20.0.164 69.20.0.196
|
||
- Container management: 172.29.236.11 - 172.29.236.13
|
||
- Tunnel: no IP (because IP exist in the containers, when the components
|
||
aren't deployed directly on metal)
|
||
- Storage: no IP (because IP exist in the containers, when the components
|
||
aren't deployed directly on metal)
|
||
|
||
- Addresses for the compute nodes:
|
||
|
||
- Host management: 10.240.0.21 - 10.240.0.22
|
||
- Host management gateway: 10.240.0.1
|
||
- DNS servers: 69.20.0.164 69.20.0.196
|
||
- Container management: 172.29.236.21 - 172.29.236.22
