The author demonstrates a method for deploying a Kubernetes cluster using Kind with Cilium as a load balancer and Gateway API for routing. The setup is designed for a Linux environment and runs on a machine with 4 CPUs and 16 GB of RAM.
The cluster consists of 9 nodes, including one control-plane and eight worker nodes. The configuration disables the default CNI and kube-proxy to allow Cilium to manage the network stack via eBPF. Worker nodes are organized into specific pools for databases, applications, storage, and web services using Kubernetes taints and labels.
To manage incoming traffic, the setup utilizes the Kubernetes Gateway API. Cilium is installed via Helm version 1.20.2 with specific configurations, including L2 announcements for LoadBalancer services and the activation of Hubble for network monitoring and visualization.
The infrastructure includes the deployment of CloudNativePG for PostgreSQL databases and SeaweedFS for S3-compatible storage. This architecture allows for testing load balancing, traffic distribution, and high availability by simulating node failures within the local environment.
