Calico’s pure L3 approach to data center networking integrates seamlessly with Mirantis OpenStack to bring simple, scalable and secure networking to your deployment.
Based on the same scalable IP network principles as the Internet, Calico implements a highly efficient vRouter in each compute node that leverages the existing Linux kernel forwarding engine without the need for vSwitches. Each vRouter propagates workload reachability information (routes) to the rest of the data center using BGP – either directly in small scale deployments or via BGP route reflectors to reach Internet level scales in large deployments.
Calico peers directly with the data center’s physical fabric (whether L2 or L3) without the need for on/off ramps, NAT, tunnels, or overlays.
With Calico, networking issues are easy to troubleshoot. Since it's all IP, standard tools such as ping and traceroute will just work.
Calico supports rich and flexible network policy which it enforces using bookended ACLs on each compute node to provide tenant isolation, security groups, and external reachability constraints.

-
Install the fuel plugin builder, fpb:
easy_install pip pip install fuel-plugin-builder
-
Clone the calico plugin repository and run the plugin builder:
git clone https://github.com/openstack/fuel-plugin-calico cd fuel-plugin-calico/ fpb --build .
-
Check that the file calico-fuel-plugin-3.0-3.0.0-0.noarch.rpm was created.
-
Prepare a clean fuel master node.
-
Copy the plugin onto the fuel master node:
scp calico-fuel-plugin-3.0-3.0.0-0.noarch.rpm root@<Fuel_Master_Node_IP>:/tmp
-
Install the plugin on the fuel master node:
cd /tmp fuel plugins --install calico-fuel-plugin-3.0-3.0.0-0.noarch.rpm
-
Check the plugin was installed:
fuel plugins --list
To deploy a cluster with the Calico plugin, use the Fuel web UI to deploy an OpenStack cluster in the usual way, with the following guidelines:
-
Create a new OpenStack environment, selecting:
Liberty on Ubuntu Trusty ( For Fuel 8.0 ) Mitaka on Ubuntu Trusty ( For Fuel 9.0 )
"Calico" as the networking setup
-
Under the settings tab, make sure the following options are checked:
"Assign public network to all nodes"
"Use Calico Virtual Networking"
-
Under the network tab, configure the 'Public' settings (leaving all of the other sections with their default values). For example (exact values will depend on your setup):
- IP Range: 172.18.203.60 - 172.18.203.69
- CIDR: 172.18.203.0/24
- Use VLAN tagging: No
- Gateway: 172.18.203.1
- Floating IP range: 172.18.203.70 - 172.18.203.79
- IP Range: 172.18.203.60 - 172.18.203.69
-
Add nodes (for meaningful testing, you will need at least two compute nodes in addition to the controller).
