Production-Ready Settings

This guide outlines the essential configuration and deployment settings required to run the MCP Weather Server in production environments.

Configuration Management

Environment Variables

The application supports flexible configuration through environment variables and appsettings.json:

# Weather service configuration
WEATHER_CHOICES="sunny,cloudy,rainy,stormy,snowy,windy,foggy"

# Logging configuration
ASPNETCORE_ENVIRONMENT=Production
Logging__LogLevel__Default=Information
Logging__LogLevel__Microsoft=Warning

Application Settings

Create an appsettings.Production.json for production-specific settings:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    },
    "Console": {
      "LogToStandardErrorThreshold": "Error"
    }
  },
  "WeatherChoices": "sunny,partly-cloudy,cloudy,overcast,light-rain,heavy-rain,thunderstorm,snow,fog,windy",
  "RandomNumber": {
    "DefaultMin": 0,
    "DefaultMax": 100
  }
}

Docker Configuration

Multi-Stage Dockerfile

# Build stage
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src
COPY ["SampleMcpServer.csproj", "./"]
RUN dotnet restore "SampleMcpServer.csproj"
COPY . .
RUN dotnet build "SampleMcpServer.csproj" -c Release -o /app/build

# Test stage
FROM build AS test
RUN dotnet test --no-build --verbosity normal --collect:"XPlat Code Coverage"

# Publish stage
FROM build AS publish
RUN dotnet publish "SampleMcpServer.csproj" -c Release -o /app/publish /p:UseAppHost=false

# Runtime stage
FROM mcr.microsoft.com/dotnet/aspnet:8.0-alpine AS final
WORKDIR /app
COPY --from=publish /app/publish .

# Create non-root user
RUN adduser -D -s /bin/sh appuser
USER appuser

# Health check
HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
    CMD dotnet SampleMcpServer.dll --health-check || exit 1
