Advanced Networking

Deep dive into Kova networking architecture.

Network Architecture

Internet → Apache (SSL) → Orchestrator Ingress → Provider Container

Components

1. Apache Reverse Proxy

   • Handles SSL/TLS termination
   • Routes based on subdomain
   • Manages Let's Encrypt certificates

2. Orchestrator Ingress

   • Maintains deployment → provider mapping
   • Proxies requests to correct provider
   • Handles health checks

3. Provider Container

   • Docker container running your app
   • Accessible via internal port mapping

DNS and Subdomains

Each deployment gets a unique subdomain:

{service}-{deployment-id}.deployments.kovanetwork.com

Example:

web-17628738.deployments.kovanetwork.com

Custom Domains

Custom domain support is planned for future releases. Currently, all deployments use the *.deployments.kovanetwork.com subdomain.

Inter-Service Communication

Services within the same deployment communicate via Docker DNS:

services:
  api:
    env:
      - DATABASE_HOST=db      # Uses service name
      - REDIS_HOST=cache

  db:
    image: postgres:15

  cache:
    image: redis:alpine
