# DeerFlow Development Environment
# Usage: docker-compose -f docker-compose-dev.yaml up --build
#
# Services:
#   - nginx: Reverse proxy (port 2026)
#   - frontend: Frontend Next.js dev server (port 3000)
#   - gateway: Backend Gateway API (port 8001)
#   - langgraph: LangGraph server (port 2024)
#   - provisioner (optional): Sandbox provisioner (creates Pods in host Kubernetes)
#
# Prerequisites:
#   - Kubernetes cluster + kubeconfig are only required when using provisioner mode.
#
# Access: http://localhost:2026

services:
  # ── Sandbox Provisioner ────────────────────────────────────────────────
  # Manages per-sandbox Pod + Service lifecycle in the host Kubernetes
  # cluster via the K8s API.
  # Backend accesses sandboxes directly via host.docker.internal:{NodePort}.
