docker（Docker 容器开发）

Docker Skill

Sorcha uses Docker for local development and production deployment. Services run as Ubuntu Chiseled (distroless) containers with multi-stage builds. Docker Compose orchestrates the full stack with health checks, shared networks, and volume mounts for persistence.

Quick Start

Start Full Stack

# Start all services with infrastructure
docker-compose up -d

# View logs for specific service
docker-compose logs -f blueprint-service

# Rebuild single service after code changes
docker-compose build blueprint-service && docker-compose up -d --force-recreate blueprint-service

Infrastructure Only (for Aspire development)

# Start databases without application services
docker-compose -f docker-compose.infrastructure.yml up -d

Key Concepts

Common Patterns

Service Definition with Dependencies

When: Adding a new microservice

my-service:
  build:
    context: .
    dockerfile: src/Services/Sorcha.MyService/Dockerfile
  image: sorcha/my-service:latest
  container_name: sorcha-my-service
  restart: unless-stopped
  environment:
    <<: [*otel-env, *jwt-env]
    OTEL_SERVICE_NAME: my-service
    ASPNETCORE_ENVIRONMENT: Development
    ASPNETCORE_URLS: http://+:8080
    ConnectionStrings__Redis: redis:6379
  volumes:
    - dataprotection-keys:/home/app/.aspnet/DataProtection-Keys
  depends_on:
    redis:
      condition: service_healthy
  networks:
    - sorcha-network

Multi-Stage Dockerfile

When: Creating Dockerfile for.NET service

FROM mcr.microsoft.com/dotnet/sdk:10.0 AS build
WORKDIR /src
COPY ["src/Services/Sorcha.MyService/Sorcha.MyService.csproj", "src/Services/Sorcha.MyService/"]
RUN dotnet restore "src/Services/Sorcha.MyService/Sorcha.MyService.csproj"
COPY src/ ./src/
RUN dotnet publish "src/Services/Sorcha.MyService/Sorcha.MyService.csproj" -c Release -o /app/publish

FROM mcr.microsoft.com/dotnet/aspnet:10.0-noble-chiseled AS final
WORKDIR /app
COPY --from=publish /app/publish .
USER $APP_UID
ENTRYPOINT ["dotnet", "Sorcha.MyService.dll"]

Documentation Resources

Fetch latest Docker documentation with Context7.

How to use Context7:

1. Use mcp__context7__resolve-library-id to search for "docker"
2. Prefer website documentation (IDs starting with /websites/) over source code repositories
3. Query with mcp__context7__query-docs using the resolved library ID

Library ID: /websites/docker *(resolve using mcp__context7__resolve-library-id, prefer /websites/ when available)*

Recommended Queries:

• "docker compose health checks"
• "multi-stage build best practices"
• "docker networking bridge mode"
