Configuring the network
|
|
-----------------------
|
|
|
|
Although Ansible automates most deployment operations, networking on
|
|
target hosts requires manual configuration because it can vary
|
|
dramatically per environment. For demonstration purposes, these
|
|
instructions use a reference architecture with example network interface
|
|
names, networks, and IP addresses. Modify these values as needed for the
|
|
particular environment.
|
|
|
|
The reference architecture for target hosts contains the following
|
|
mandatory components:
|
|
|
|
- A ``bond0`` interface using two physical interfaces. For redundancy
|
|
purposes, avoid using more than one port on network interface cards
|
|
containing multiple ports. The example configuration uses ``eth0``
|
|
and ``eth2``. Actual interface names can vary depending on hardware
|
|
and drivers. Configure the ``bond0`` interface with a static IP
|
|
address on the host management network.
|
|
|
|
- A ``bond1`` interface using two physical interfaces. For redundancy
|
|
purposes, avoid using more than one port on network interface cards
|
|
containing multiple ports. The example configuration uses ``eth1``
|
|
and ``eth3``. Actual interface names can vary depending on hardware
|
|
and drivers. Configure the ``bond1`` interface without an IP address.
|
|
|
|
- Container management network subinterface on the ``bond0`` interface
|
|
and ``br-mgmt`` bridge with a static IP address.
|
|
|
|
- The OpenStack Networking VXLAN subinterface on the ``bond1``
|
|
interface and ``br-vxlan`` bridge with a static IP address.
|
|
|
|
- The OpenStack Networking VLAN ``br-vlan`` bridge on the ``bond1``
|
|
interface without an IP address.
|
|
|
|
The reference architecture for target hosts can also contain the
|
|
following optional components:
|
|
|
|
- Storage network subinterface on the ``bond0`` interface and
|
|
``br-storage`` bridge with a static IP address.
