CTO Agent 2c0e7f22b1 Add k3s cluster management automation and documentation 
- Add k3s node provisioning script with version pinning
- Add comprehensive K3S_OPERATIONS.md documentation
- Add k3s system-upgrade-controller configuration

This addresses DEV-221: prevents version skew issues by:
1. Enforcing version pinning when adding new nodes
2. Providing automated provisioning script
3. Setting up automated upgrades via upgrade controller
4. Documenting all cluster operations procedures

Purpose

This repository serves as the central source of truth for all deployment configurations targeting the basicstack.de Kubernetes cluster. It follows GitOps principles where infrastructure and application state is declaratively defined and version-controlled.

Directory Details

apps/

Contains deployment configurations for individual applications and services running on the cluster. Each application should have its own subdirectory with:

  • Kubernetes manifests (Deployments, StatefulSets, Services, etc.)
  • Helm values files
  • Configuration files
  • Application-specific documentation

Example: The stalwart/ directory contains the complete deployment configuration for the Stalwart mail server, including multiple deployment variants, monitoring setup, and operational guides.

infrastructure/

Contains cluster-wide infrastructure configurations:

  • networking/: Ingress controllers, network policies, DNS configurations, load balancers
  • monitoring/: Prometheus, Grafana, logging infrastructure, observability tools

docs/

General documentation including:

  • Deployment procedures
  • Cluster architecture
  • Troubleshooting guides
  • Best practices

Getting Started

  1. Clone this repository
  2. Review the example Stalwart deployment in apps/stalwart/
  3. Follow the pattern for new application deployments
  4. Ensure all manifests are tested before committing

Contributing

All changes should be:

  1. Committed with clear, descriptive messages
  2. Tested in a development environment when possible
  3. Documented appropriately
  4. Reviewed before deployment to production

Cluster Information

  • Cluster: basicstack.de
  • Platform: K3s on Hetzner Cloud
  • Namespace Strategy: One namespace per application (recommended)
  • Ingress: Traefik (default K3s ingress controller)
