Configuration Reference

Asantiya uses a YAML configuration file called deploy.yaml to define your deployment settings. This file should be placed in the root directory of your project.

Configuration File Structure

Here’s a complete example of a deploy.yaml configuration file:

# Main application configuration
service: my-awesome-app
image: my-awesome-app-image
app_ports: 8080:80
host: false
 
# Builder configuration
builder:
  arch: amd64
  local: true
  remote: ssh://user@server
  dockerfile: Dockerfile
  build_args:
    NODE_ENV: production
 
# Accessories (additional services)
accessories:
  postgres:
    service: my-awesome-app-db
    image: postgres:13
    ports: 5432:5432
    env:
      POSTGRES_PASSWORD: secret
      POSTGRES_DB: myapp
    volumes:
      - db_data:/var/lib/postgresql/data
    network: my-app-network
    depends_on: []
    options:
      restart: always

Core Configuration Options

Main Application Settings

Service Name

The service field defines the name of your application service. This name is used as the container name and for service identification.

service: myapp

Best Practices:

• Use lowercase letters, numbers, and hyphens only
• Keep it descriptive but concise
• Avoid special characters and spaces

Image Name

The image field specifies the Docker image name that will be built and used for your application.

image: my-app-image

Best Practices:

• Use descriptive names that reflect your application
• Consider including version tags for production deployments
• Follow Docker naming conventions

Port Mapping

The app_ports field maps host ports to container ports.

# Map host port 8080 to container port 80
app_ports: "8080:80"

Common Port Mappings:

• Web applications: "8080:80" or "8080:3000"
• API services: "8080:8000"
• Database: "5432:5432" (PostgreSQL)

Host Configuration

The host field determines if the application runs on the host machine or in a container.

host: false  # Run in container (default)
host: true   # Run on host machine

Advanced Configuration

Builder Options

Configure how your Docker image is built. See Builders for detailed information.

builder:
  local: true          # Use local Docker daemon
  arch: amd64          # Target architecture
  dockerfile: Dockerfile.production
  remote: ssh://docker@builder-server

Accessories

Define additional services like databases, caches, and message queues. See Accessories for detailed information.

accessories:
  postgres:
    service: postgres
    image: postgres:15-alpine
    port: "5432:5432"
    env:
      - POSTGRES_DB=myapp
      - POSTGRES_USER=user
      - POSTGRES_PASSWORD=password
    volumes:
      - postgres_data:/var/lib/postgresql/data
    options:
      restart: always
