ASPNET Docker Compose — Multi-Container Orchestration for .NET Apps

DodaTech Updated 2026-06-28 1 min read

In this tutorial, you'll learn about ASPNET Docker Compose. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

Docker Compose orchestrates multi-container .NET applications with databases, caches, and Message Queues defined in a single YAML configuration.

services:
  api:
    build:
      context: .
      dockerfile: ScanApi/Dockerfile
    ports: ["5000:8080"]
    environment:
      - ASPNETCORE_ENVIRONMENT=Staging
      - Redis__ConnectionString=redis:6379
      - ConnectionStrings__DefaultServer=Server=db;Database=scandb;User=sa;
    depends_on:
      db: { condition: service_healthy }
      redis: { condition: service_started }
    volumes: ["${PWD}/logs:/app/logs"]
    restart: unless-stopped

  db:
    image: mcr.microsoft.com/mssql/server:2022-latest
    environment:
      - ACCEPT_EULA=Y
      - SA_PASSWORD=${SA_PASSWORD}
    healthcheck:
      test: /opt/mssql-tools/bin/sqlcmd -S localhost -U sa -P ${SA_PASSWORD} -Q "SELECT 1"
      interval: 10s
    volumes: ["sqldata:/var/opt/mssql"]

  redis:
    image: redis:7-alpine
    ports: ["6379:6379"]
    healthcheck: { test: ["CMD", "redis-cli", "ping"], interval: 5s }

volumes: { sqldata: }

Docker Compose simplifies local development and staging environments by managing all service dependencies automatically.
