loxilb-io / loxi-ccm

K8s CCM plugin implementation for loxilb

What is loxi-ccm

loxi-ccm is a CCM provider that exposes service type external load-balancer implemented by loxilb for kubernetes . Kubernetes provides the cloud-provider interface for the implementation of external cloud provider-specific control logic, and loxi-ccm is an implementation of the cloud-provider interface.

Deploy loxi-ccm on kubernetes

The guide below has been tested in environment on Ubuntu 20.04, kubernetes v1.24 (calico CNI)

1. Modify k8s ConfigMap

In the manifests/loxi-ccm.yaml manifests file, the ConfigMap is defined as follows

---
apiVersion: v1
kind: ConfigMap
metadata:
  name: loxilb-config
  namespace: kube-system
data:
  apiServerURL: "http://192.168.20.54:11111"
  externalIPcidr: 123.123.123.0/24
---

The ConfigMap has two values: apiServerURL and externalIPcidr.

• apiServerURL : API Server address of loxilb.
• externalIPcidr : Subnet band to be allocated by loxilb as External IP of the load balancer.

apiServerURL and externalIPcidr must be modified according to the environment of the user using loxi-ccm.

2. Deploy loxi-ccm

Once you have modified ConfigMap, you can deploy loxi-ccm using the loxi-ccm.yaml manifest file. Run the following command on the kubernetes you want to deploy.

kubectl apply -f https://github.com/loxilb-io/loxi-ccm/raw/master/manifests/loxi-ccm.yaml

After entering the command, check whether loxi-cloud-controller-manager is created in the daemonset of the kube-system namespace.
