DIY: Create Your Own Cloud with Kubernetes (Part 1)

Kubernetes' versatility allows for bare metal cloud deployments, requiring a foundational layer for installation and maintenance. Talos Linux offers a hybrid approach for bare metal updates, minimizing service disruptions. Preparing the base infrastructure involves considerations such as kernel updates, kernel modules, and system image creation. PXE booting serves as a method for deploying the initial cluster. Delivering system components can be automated through GitOps practices using tools like FluxCD, which allows for declarative configuration of necessary charts. FluxCD ensures that clusters are brought to the desired state and maintain their configuration over time. The platform includes pre-configured Helm charts for system components such as cert-manager, cilium, and kubevirt. By utilizing these open-source technologies, bare metal clouds can be established with dynamic provisioning, load balancing, and autoscaling capabilities.
