The andrelair-platform organization is my personal homelab running as real production infrastructure — built to gain hands-on experience with the full platform engineering lifecycle, from bare-metal provisioning to GitOps delivery and AI services. 5 laptops (4 ThinkPad X390s + 1 MacBook Pro 2012), zero managed cloud:
Infrastructure layer
- MAAS bare-metal provisioning (PXE boot, Ubuntu 22.04, cloud-init)
- k3s cluster (1 control-plane + 4 workers) behind Tailscale mesh
- Longhorn distributed storage · Velero backups → MinIO
GitOps & delivery
- ArgoCD app-of-apps · Kustomize base+overlays · 3-branch CI promotion (dev → staging → prod)
- Harbor private registry with cosign image signing + SBOM
- 8 custom service repos, each with full CI on GitHub Actions
Platform services
- SSO: Authentik OIDC protecting ArgoCD, Grafana, Harbor, Backstage, Vault, Open WebUI
- Secrets: HashiCorp Vault with Kubernetes auth + AWS KMS auto-unseal
- Admission control: OPA Gatekeeper in deny mode across 23 namespaces
- Observability: Prometheus · Grafana · Loki · Tempo · Alertmanager
AI services
- Self-hosted LLMs: Ollama + Open WebUI
- RAG pipeline: document ingestion → Docling/MarkItDown → chunking → embeddings → pgvector
- LLM eval & tracing: LiteLLM router + Langfuse · phi3-financial PromptOps pipeline
62 automated regression checks. 35+ phases completed.
