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.
