Local Development Setup

Overview

This guide explains how to set up Hive for local development when you don't have access to the production domain hive.home.deepblack.cloud.

Custom DNS Setup

Option 1: Edit /etc/hosts (Recommended)

Add the following entries to your /etc/hosts file:

127.0.0.1 hive.home.deepblack.cloud
127.0.0.1 hive-api.home.deepblack.cloud
127.0.0.1 hive-grafana.home.deepblack.cloud
127.0.0.1 hive-prometheus.home.deepblack.cloud

Option 2: Use Local Domain

Alternatively, you can modify docker-compose.swarm.yml to use a local domain:

1. Replace all instances of hive.home.deepblack.cloud with hive.localhost
2. Update the CORS_ORIGINS environment variable:

   export CORS_ORIGINS=https://hive.localhost
   

Port Access

When running locally, you can also access services directly via ports:

• Frontend: http://localhost:3001
• Backend API: http://localhost:8087
• Grafana: http://localhost:3002
• Prometheus: http://localhost:9091
• PostgreSQL: localhost:5433
• Redis: localhost:6380

CORS Configuration

For local development, you may need to adjust CORS settings:

# For development with localhost
export CORS_ORIGINS="http://localhost:3000,http://localhost:3001,https://hive.localhost"

# Then deploy
docker stack deploy -c docker-compose.swarm.yml hive

SSL Certificates

Development Mode (HTTP)

For local development, you can disable HTTPS by:

1. Removing the TLS configuration from Traefik labels
2. Using web instead of web-secured entrypoints
3. Setting up a local Traefik instance without Let's Encrypt

Self-Signed Certificates

For testing HTTPS locally:

1. Generate self-signed certificates for your local domain
2. Configure Traefik to use the local certificates
3. Add the certificates to your browser's trusted store

Environment Variables

Create a .env file with local settings:

# .env for local development
CORS_ORIGINS=http://localhost:3000,http://localhost:3001,https://hive.localhost
DATABASE_URL=postgresql://hive:hivepass@postgres:5432/hive
REDIS_URL=redis://redis:6379
ENVIRONMENT=development
LOG_LEVEL=debug

Troubleshooting

DNS Not Resolving

If custom domains don't resolve:

1. Check your /etc/hosts file syntax
2. Clear your DNS cache: sudo systemctl flush-dns (Linux) or sudo dscacheutil -flushcache (macOS)
3. Try using IP addresses directly

CORS Errors

If you see CORS errors:

1. Check the CORS_ORIGINS environment variable
2. Ensure the frontend is accessing the correct backend URL
3. Verify the backend is receiving requests from the expected origin

SSL Certificate Errors

If you see SSL certificate errors:

1. Use HTTP instead of HTTPS for local development
2. Add certificate exceptions in your browser
3. Use a local certificate authority

Alternative: Development Docker Compose

You can create a docker-compose.dev.yml file specifically for local development:

# Simplified version without Traefik, using direct port mapping
services:
  hive-backend:
    # ... same config but without Traefik labels
    ports:
      - "8000:8000"  # Direct port mapping
    environment:
      - CORS_ORIGINS=http://localhost:3000
  
  hive-frontend:
    # ... same config but without Traefik labels  
    ports:
      - "3000:3000"  # Direct port mapping

Then run with:

docker-compose -f docker-compose.dev.yml up -d
