## Deployment and Orchestration
### Gitops
#### Argocd and Flux
- **(2023)** [flux-subsystem-argo.github.io: GitOps Terraform Resources with Argo CD and Flux Subsystem for Argo](https://flux-subsystem-argo.github.io/website/tutorials/terraform) <span class='md-tag md-tag--warning'>[GO CONTENT]</span> <span class='md-tag md-tag--critical'>[ADVANCED LEVEL]</span> 🌟🌟🌟 <span class='md-tag md-tag--info'>[COMMUNITY-TOOL]</span> <span class='md-tag md-tag--secondary'>[GUIDE]</span> — Examines the integration of Flux's specialized controller capabilities with Argo CD's visual application management via the Flux Subsystem for Argo (FSA). Highlights the declarative orchestration of Terraform/OpenTofu resources. Live Grounding notes that while hybrid Argo-Flux architectures exist, most modern 2026 enterprise teams prefer consolidated control planes (e.g., pure Crossplane or pure Tofu-Controller) to limit orchestration overhead.
#### Cluster Provisioning
- **(2024)** [==github.com/onedr0p/flux-cluster-template: Template for deploying k3s backed by Flux==](https://github.com/onedr0p/cluster-template) <span class='md-tag md-tag--info'>⭐ 2760</span> <svg class="v2-sparkline" width="50" height="15" viewBox="0 0 50 15" style="vertical-align: middle; display: inline-block; margin-left: 6px;" title="Activity Trend"><defs><linearGradient id="spark-grad-74ad0e62" x1="0" y1="0" x2="1" y2="0"><stop offset="0%" stop-color="rgba(34, 211, 238, 0.2)" /><stop offset="100%" stop-color="var(--md-accent-fg-color)" /></linearGradient></defs><path class="v2-sparkline-path" d="M 0 8 L 10 7 L 20 7 L 30 5 L 40 9 L 50 5" fill="none" stroke="url(#spark-grad-74ad0e62)" stroke-width="1.5" stroke-linecap="round" stroke-linejoin="round" /><circle cx="50" cy="5" r="2" fill="var(--md-accent-fg-color)" /></svg> <span class='md-tag md-tag--warning'>[YAML CONTENT]</span> 🌟🌟🌟🌟🌟 <span class='md-tag md-tag--success'>[DE FACTO STANDARD]</span> — A production-grade template repository for provisioning home-lab and enterprise-edge K3s clusters managed end-to-end via Flux GitOps.
