GeoCrop System Architecture

+
+ {/* Simplified SVG Architecture Diagram */} + + + React Frontend + + + + + FastAPI Gateway + + + + + ML Worker + + + Redis Queue + + + + + + MinIO (S3) + + + PostGIS DB + + + + + + + + + + +
+
+
+

Tech Rationale

+
    +
  • MinIO: Local data sovereignty + S3 compatibility for geospatial artifacts.
    • +
  • Redis: Decouples long-running ML inference from API response times.
    • +
  • TiTiler: Dynamic COG tiling directly from MinIO without intermediate storage.
    • +
+
+
+

Data Flow

+

+ Requests flow from the React frontend to the FastAPI gateway, which enqueues jobs in Redis. + The ML Worker pulls STAC data from Digital Earth Africa, runs inference, and persists COGs to MinIO. +

+
+
+
+ ); + case 'infrastructure': + return ( +
+

Infrastructure Design (K3s)

+

A production-grade Sovereign MLOps cluster designed for low-resource environments.

+
+
+

Resource Strategy

+
    +
  • Namespaces: Logical isolation using geocrop and argocd.
    • +
  • API/Web: Capped at 512MB RAM to maximize efficiency.
    • +
  • Worker/Jupyter: Allocated up to 2GB for heavy ML compute.
    • +
+
+
+

GitOps Layer

+
    +
  • Argo CD: Automated synchronization between Git and the Cluster.
    • +
  • Gitea: Lightweight self-hosted Git service and CI runner.
    • +
  • Terraform: Infrastructure as Code for namespaces and volumes.
    • +
+
+
+
+

Principle: "Everything deployed is version-controlled, reproducible, and vendor-agnostic."

End-to-End MLOps Workflow

+
+
+
+

1. Data Ingestion & Training

+

Zimbabwe crop labels are batched and stored in MinIO. Training is executed in Jupyter or via automated scripts in the cluster.

+
+
+
+

2. Experiment Tracking (MLflow)

+

All runs log parameters, metrics, and models to MLflow at ml.techarvest.co.zw, ensuring full reproducibility.

+
+
+
+

3. CI/CD & Deployment

+

Gitea Actions build the Worker container. Argo CD detects the update and rolls out the new model to the production cluster.

+
+
+
+ ); + case 'decisions': + return ( +
+

Engineering Decisions & Trade-offs

+
+
+

Argo vs Kubeflow

+

+ Decision: Argo CD + Argo Workflows.
+ Rationale: Kubeflow is too resource-heavy for a single-node VPS. Argo provides the necessary automation with a fraction of the RAM overhead. +

+
+
+

Gitea vs GitLab

+

+ Decision: Gitea.
+ Rationale: GitLab requires 4GB+ RAM just to start. Gitea runs comfortably on 256MB, providing high-performance source control and CI for small clusters. +

+
+
+

Standalone PostGIS

+

+ Decision: Replaced Supabase with native PostGIS container.
+ Rationale: Removed the GoTrue/PostgREST/Kong overhead while retaining critical spatial query capabilities for geospatial ML. +

+
+
+

MinIO Storage

+

+ Decision: On-cluster S3-compatible storage.
+ Rationale: Guarantees data sovereignty and reduces egress costs/latency when training models on large satellite datasets. +

+
+
+
+ ); + case 'observability': + return ( +
+

Observability & Monitoring

+
+

The platform maintains 99.9% visibility through a layered monitoring stack.
