Plan d'action

Phase 1 - Fondations (FAIT)

• WSL2 Debian installe
• Terraform, Ansible, Git installes
• Cle SSH homelab generee
• Template cloud-init Rocky 9 (VMID 9000)
• Token API Proxmox (terraform@pam!provider)
• Fichiers Terraform + Ansible ecrits

Phase 2 - Provisionnement VMs

• terraform apply (creer les 4 VMs)
• Verifier acces SSH aux VMs (ping + ansible ping OK)

Phase 3 - Configuration (Ansible)

• base.yml (users, SSH hardening, firewalld, qemu-agent)
• Installer collections Ansible (ansible.posix, community.docker, community.general)
• Ansible Vault (secrets BDD chiffres)
• ansible-playbook site.yml (docker, services)

Phase 4 - Services

• Forgejo + PostgreSQL deploye
• Stirling PDF deploye
• Nextcloud + PostgreSQL deploye
• NFS QNAP monte (nextcloud-data, backups crees sur QNAP)

Phase 5 - Exposition externe

• Acheter NDD elewyn.dev (~7 EUR/an)
• Louer VPS Scaleway PLAY2-PICO (~4 EUR/mois) - 51.158.126.113
• WireGuard VPS <-> gateway (10.0.0.1 <-> 10.0.0.2)
• Caddy reverse proxy + TLS Let's Encrypt
• DNS Cloudflare (forge.elewyn.dev, cloud.elewyn.dev)

Phase 6 - QNAP

• Creer shares NFS (nextcloud-data)
• Creer share NFS backups
• Configurer backups vzdump Proxmox -> NFS (storage qnap-backups, schedule nuit)
• Remplacer disque HS + RAID reconstruit

Phase 7 - Kubernetes (futur)

• VM k3s single-node (6 Go RAM)
• Migration progressive des services
• ArgoCD (GitOps)
• Monitoring (Grafana/Loki/Prometheus)
