- This kubernetes
clusternode is currently run on a Dell Optiplex 3050 SFF with 4 Cores, 8 Threads and 32gb RAM. - Proxmox for the hypervisor with a Ubuntu Server 20.04lts VM with 500gb nvme boot drive and a 240gb SSD scratch drive for downloading and unzipping *arrs.
- Synology NAS with 6* 6tb Seagate exos drives in a 24TB pool for computer and cloud backups and plex media storage.
- HP Microserver gen 8 (i3-3240T, 16gb ram) runs Proxmox for the hypervisor for a pi-hole LXT and a OpnSense VM for the router (with passthrough intel NICs)
- Raspberry Pi 4 8gb will be a master and worker node for some ARM64 packages.

This cluster uses a number of tools to work properly:
- Kubernetes k3s - Production-Grade Container Orchestration, automated container deployment, scaling, and management.
- K3sup- uses Ansible to deploy a lightweight k3s production ready cluster.
- Containerd - an industry-standard container runtime with an emphasis on simplicity, robustness and portability.
- Flux2 - open and extensible continuous delivery solution for Kubernetes. Powered by GitOps Toolkit.
- Github - code hosting platform for version control and collaboration.
- Github actions - CI/CD runner for workflows
- Renovate - universal dependency update tool that fits into your workflows.
- Calico - an open source networking and network security solution for containers.
- Cloudflare DDNS - service that keeps the DNS updated with a web property's correct IP address.
- Cloudflare Tunnels - secure and encrypt application traffic to any type of infrastructure
MetalLB - load-balancer implementation for bare metal Kubernetes clusters.
Very much a work in progress, It'll be finished over the coming months. Subject to change.
