Overview
When running Ringee with docker-compose.app.yml, several environment variables are automatically overridden to use Docker’s internal networking. You don’t need to manually set these.
Automatic Overrides
The following variables are set automatically by Docker Compose:
| Variable | Docker Value |
|---|
DATABASE_URL | postgresql://ringee-user:ringee-password@postgres:5432/ringee-db-local?schema=public |
REDIS_HOST | redis |
REDIS_PORT | 6379 |
REDIS_URL | redis://redis:6379 |
The hostnames postgres and redis refer to the Docker internal service names. These are resolved automatically by Docker’s internal DNS.
Volumes
The default Docker Compose configuration creates the following persistent volumes:
| Volume | Purpose |
|---|
postgres-data | PostgreSQL database files |
redis-data | Redis persistence data |
Ports
Default port mapping:
| Service | Host Port | Container Port |
|---|
| Admin Frontend | 4200 | 4200 |
| Consumer Frontend | 4201 | 4201 |
| Backend API | 3000 | 3000 |
| PostgreSQL | 5432 | 5432 |
| Redis | 6379 | 6379 |
Customizing ports
To change the host ports, modify the ports section in docker-compose.app.yml:
services:
frontend:
ports:
- "8080:4200" # Access admin on port 8080 instead
If you change the frontend or backend ports, remember to update the corresponding FRONTEND_URL, PUBLIC_BACKEND_URL, and NEXT_PUBLIC_API_BASE_URL environment variables accordingly.
Rebuilding
After making changes to the codebase or environment:
# Rebuild and restart all containers
docker-compose -f docker-compose.app.yml up --build -d
# Rebuild only a specific service
docker-compose -f docker-compose.app.yml up --build -d backend
