Cilium is an innovative open-source project that redefines networking and security for containerized applications. By leveraging the power of eBPF (extended Berkeley Packet Filter), Cilium provides efficient networking and transparent security capabilities for modern cloud-native environments. Readers exploring Cilium can gain insights into advanced networking concepts, such as service mesh architectures, network policy enforcement, and distributed application security.

Talos is an immutable operating system designed to run Kubernetes, providing an out-of-the-box Kubernetes installation with a smaller attack surface and easier maintenance. This guide explains how to bootstrap and upgrade a multi-node Talos cluster running VMs on Proxmox, using OpenTofu/Terraform and following IaC principles. The setup includes configuring Talos and Proxmox, using Cilium for enhanced networking, leveraging the Proxmox CSI plugin for volume provisioning, and optionally using Intel iGPU for video support. It also covers advanced configurations like setting up Sealed Secrets for secure secret management and customising Talos images with Talos Linux Image Factory.
