Networking Configuration

This guide explains Agenta's network topology, how containers communicate with each other, and the environment variables that control networking behavior and connectivity.

Network Topology

Agenta uses a Docker-based network architecture with a dedicated bridge network for container communication and Traefik as the reverse proxy for external access.

Container Communication Patterns

External Access Flow

Internet → Traefik (80/443) → Internal Services
├── / → web:3000 (Frontend)
├── /api/ → api:8000 (Backend API)
├── /services/completion/ → completion:80
└── /services/chat/ → chat:80

Internal Service Communication

Web Container:
├── → api:8000 (Backend API calls)
└── → completion:80, chat:80 (Direct playground calls)

API Container:
├── → postgres:5432 (Database operations)
├── → redis:6379 (Task queue, caching, sessions)
├── → supertokens:3567 (Authentication)
└── → worker (Task delegation via TaskIQ)

Worker Container:
├── → redis:6379 (Task queue via TaskIQ)
├── → postgres:5432 (Data access)
└── → completion:80, chat:80 (AI operations)

Network Environment Variables

External Access Configuration

These variables control how external users access Agenta:

Variable	Purpose	Example	Description
`TRAEFIK_DOMAIN`	Domain routing	`localhost`, `agenta.mydomain.com`	Primary domain for routing
`TRAEFIK_PORT`	HTTP port	`80`	External HTTP port
`TRAEFIK_HTTPS_PORT`	HTTPS port	`443`	External HTTPS port
`AGENTA_API_URL`	API endpoint	`http://localhost/api`	External API URL
`AGENTA_WEB_URL`	Frontend URL	`http://localhost`	External frontend URL
`AGENTA_SERVICES_URL`	Services URL	`http://localhost/services`	External services URL template
`AGENTA_API_INTERNAL_URL`	Internal API URL between services and backend	`http://host.docker.internal/api`	Internal API URL

Internal Service Communication

These variables configure how containers communicate internally. Use REDIS_URI for a single Redis instance, or split with the volatile/durable URLs for separate caches and queues.

Variable	Purpose	Example	Description
`POSTGRES_URI_CORE`	Core database	`postgresql+asyncpg://user:pass@postgres:5432/agenta_core`	Core database connection
`POSTGRES_URI_TRACING`	Tracing database	`postgresql+asyncpg://user:pass@postgres:5432/agenta_tracing`	Tracing database connection
`POSTGRES_URI_SUPERTOKENS`	Auth database	`postgresql://user:pass@postgres:5432/agenta_supertokens`	SuperTokens database connection
`REDIS_URI`	Single Redis (fallback)	`redis://redis:6379/0`	Used when split URLs are not set
`REDIS_URI_VOLATILE`	Redis for caches/channels	`redis://redis-volatile:6379/0`	Falls back to `REDIS_URI`
`REDIS_URI_DURABLE`	Redis for queues/streams	`redis://redis-durable:6381/0`	Falls back to `REDIS_URI`
`SUPERTOKENS_CONNECTION_URI`	Auth service	`http://supertokens:3567`	SuperTokens service URL

Port Mapping (Optional)

These variables control external port exposure for direct access:

Variable	Default	Purpose	Description
`POSTGRES_PORT`	`5432`	Database access	External PostgreSQL port (development)
`NGINX_PORT`	`80`	Alternative proxy	Nginx port (when using Nginx)

Traffic Routing Rules

Traefik Routing Configuration

Frontend Routing

# Route: / → web:3000
Rule: Host(`${TRAEFIK_DOMAIN}`) && PathPrefix(`/`)
Target: web:3000
Processing: Direct forwarding
SSL: Automatic (production)

API Routing

# Route: /api/ → api:8000
Rule: Host(`${TRAEFIK_DOMAIN}`) && PathPrefix(`/api/`)
Target: api:8000
Processing: Strip `/api` prefix
Middleware: Path prefix stripping

AI Services Routing

# Completion Service
Rule: Host(`${TRAEFIK_DOMAIN}`) && PathPrefix(`/services/completion/`)
Target: completion:80
Processing: Strip `/services/completion` prefix

# Chat Service
Rule: Host(`${TRAEFIK_DOMAIN}`) && PathPrefix(`/services/chat/`)
Target: chat:80
Processing: Strip `/services/chat` prefix

SSL/TLS Configuration

Development (HTTP)

TRAEFIK_PORT=80
AGENTA_API_URL=http://localhost/api
AGENTA_WEB_URL=http://localhost

Production (HTTPS)

TRAEFIK_PORT=80
TRAEFIK_HTTPS_PORT=443
AGENTA_SSL_DIR=/path/to/certificates
AGENTA_API_URL=https://agenta.mydomain.com/api
AGENTA_WEB_URL=https://agenta.mydomain.com

SSL Certificate Management

Automatic: Let's Encrypt via Traefik (HTTP challenge)
Storage: ${AGENTA_SSL_DIR}/acme.json
Renewal: Automatic every 60-90 days
Redirect: HTTP → HTTPS automatic

::: info Network Security The services are isolated within Docker bridge network. None of the services are exposed to the host network (except Traefik) :::

Troubleshooting Network Issues

Connection Testing

# Test database connectivity
docker exec :container-name: nc -zv postgres 5432

# Test Redis connectivity
docker exec :container-name: redis-cli -h redis ping

Port Conflicts

# Check port usage
sudo netstat -tulpn | grep :80
sudo lsof -i :443

# View container port mappings
docker ps --format "table {{.Names}}\t{{.Ports}}"

Traefik Routing Issues

# Access Traefik dashboard
http://localhost:8080

# Check Traefik logs
docker logs :container-name:

# Verify service registration
curl -s http://localhost:8080/api/http/services

DNS Resolution

# Test external domain resolution
nslookup agenta.mydomain.com
dig agenta.mydomain.com +short

# Test from multiple DNS servers
nslookup agenta.mydomain.com 8.8.8.8
nslookup agenta.mydomain.com 1.1.1.1
