Kubernetes Fury Networking

Kubernetes Fury Networking implements in-cluster networking functionality for the Kubernetes Fury Distribution (KFD) via Container Network Interface (CNI) plugins.

If you are new to KFD please refer to the official documentation on how to get started with KFD.

Overview

Kubernetes has adopted the Container Network Interface (CNI) specification for managing network resources on a cluster.

Kubernetes Fury Networking makes use of CNCF recommended Project Calico, open-source networking and network security solution for containers, virtual machines, and bare-metal workloads, to bring networking features to the Kubernetes Fury Distribution.

Calico deployment consists of a daemon set running on every node (including control-plane nodes) and a controller.

Kubernetes Fury Networking provides the following packages:

Package	Version	Description
calico	3.23.2	Calico CNI Plugin. For cluster with < 50 nodes.
ip-masq	2.5.0	The ip-masq-agent configures iptables rules to implement ip-masq functionality

Usage

Prerequisites

Tool	Version	Description
furyctl	>=0.6.0	The recommended tool to download and manage KFD modules and their packages. To learn more about furyctl read the official documentation.
kustomize	>=3.5.0	Packages are customized using kustomize. To learn how to create your customization layer with kustomize, please refer to their repository.

Deployment

⚠️ please notice that the Calico packages is for cluster with less the 50 nodes. If your cluster has more than 50 nodes, you'll need to switch to Calico + Typha.

1. List the packages you want to deploy and their version in a Furyfile.yml

bases:
  - name: networking/calico
    version: "v1.9.0"

See furyctl documentation for additional details about Furyfile.yml format.

2. Execute furyctl vendor -H to download the packages

3. Inspect the download packages under ./vendor/katalog/networking.

4. Define a kustomization.yaml that includes the ./vendor/katalog/networking directory as a resource.

resources:
- ./vendor/katalog/networking/calico

5. To deploy the packages to your cluster, execute:

kustomize build . | kubectl apply -f -
