Overview

This document describes interoperation between the controller and the CNI plug-in, and between

the controller and the Calico CNI plug-in.

• After the CNI plug-in is installed, the Pods can onboard to the controller and communicate

with each other at Layer 2 and Layer 3. The Pods can provide security group, QoS, and

network policy features. The container IP address can be a static IP, an IP address in a static

IP address pool, or an IP address in a DHCP pool on the controller. Cluster IP, Node Port, and

DNS services are supported.

• After the Calico CNI plug-in is installed, the plug-in establishes a BGP peer relationship with

leaf switches in the data center for communications between Pods through EVPN at Layer 2

and Layer 3.

Configure basic controller settings

Log in to the controller

After you deploy the controller, the related menus will be displayed on IMC PLAT. You can use

controller features after logging in to IMC PLAT.

To log in to IMC PLAT, enter http://cluster northbound IP:30000/central/index.html in the address

bar, and then press Enter.

• ucenter_ip_address is the virtual IP address for northbound services provided by the Installer

cluster where IMC PLAT is deployed.

• 30000 is the port number.

Figure 1 Logging in to IMC PLAT

Configure fabrics

1. Navigate to the Automation > Data Center Networks > Fabrics > Fabrics page. Click Add

to create a fabric.

 Specify a name for the fabric. In this example, the name is fabric1.

 Specify an AS number. Make sure the AS number is the same as the BGP AS number of

the devices in the fabric. In this example, the AS number is 100.

 Multicast network is disabled by default.

 End point group (EPG) controller is disabled by default.

 Configure other parameters as needed. In this example, the default settings are used.

2. Click Apply.

3. Click Details to obtain the UUID of the tenant. For interoperation with a Calico network, you

do not need to obtain the UUID.

Configure interoperability between the

CNI plug-in and the controller

Restrictions and guidelines

• The controller can interoperate with multiple Kubernetes container clouds. You must follow

these restrictions and guidelines:

 The hostname for the Nodes on multiple Kubernetes container clouds cannot be the

same.

 Multiple Kubernetes container clouds cannot share the same vNetwork if static IPs are

used.

• Change the cluster IP corresponding to kube-dns in the coredns.yaml file to the address

shipped with K8s before you install the DNS plug-in.

a. Display the cluster IP address for kube-dns.

[root@k8s-master140 yml]# kubectl get svc -n kube-system

Network planning

Network topology

Figure 11 Network diagram

The K8s cluster contains one master node and two worker nodes, without any bare metal server

deployed. Plan the network as follows:

• K8s master node—Configure one bond interface as the management network.

• K8s work node 1—Configure two bond interfaces.

 One bond interface is used as the management network. A management address is

required.

 The other bond interface is used as the service network. No IP address is required.

• K8s worker node 2—Configure two bond interfaces.

 One bond interface is used as the management network. A management address is

required.

 The other bond interface is used as the service network. No IP address is required.

In the test environment, three nodes are available. One node is the master. Only a management

address is required, and the management interface onboards to the controller. The other two nodes

are configured with a management address and a service address, respectively. The management

address onboards on the controller.
