在 Docker Compose 中运行时如何将参数传递给 .NET C# 控制台应用程序？

Question

我正在使用 Docker Compose 来运行 .NET C# 控制台应用程序。我需要在应用程序启动时将命令行参数传递给它，但我在日志中收到以下错误：

2025-01-15 13:07:47 System.ArgumentException: Required input args was empty. (Parameter 'args')
2025-01-15 13:07:47 at Ardalis.GuardClauses.GuardClauseExtensions.NullOrEmpty[T](IGuardClause guardClause, IEnumerable`1 input, String parameterName, String message, Func`1 exceptionCreator)
2025-01-15 13:07:47 at Personnel.Infrastructure.Migrator.Program.Main(String[] args) in C:\Users\user\RiderProjects\staffpro.learn.redkozubov\src\Services\Personnel\Infrastructure\Personnel.Infrastructure.Migrator\Program.cs:line 21

这是我的 Personnel_migrator 容器的 Docker Compose：

personnel_migrator:
    container_name: personnel_migrator
    build:
        context: .
        dockerfile: src/Services/Personnel/Infrastructure/Personnel.Infrastructure.Migrator/Dockerfile
    depends_on:
        - personnel_db
    networks:
        - personnel_db
    ports:
        - "5001:5001"
    environment:
        - CONNECTION_STRING=${CONNECTION_STRING}
    command: dotnet Personnel.Infrastructure.Migrator.dll --${CONNECTION_STRING}

我的 .env 文件包含：

CONNECTION_STRING="ConnectionString"

应用程序期望传递参数，但应用程序启动时 args 数组显示为空。如何在 Docker Compose 中正确地将命令行参数传递给 .NET 应用程序？

更新了 Docker Compose 服务

personnel_migrator:
container_name: personnel_migrator
build:
    context: .
    dockerfile: src/Services/Personnel/Infrastructure/Personnel.Infrastructure.Migrator/Dockerfile
depends_on:
    - personnel_db
networks:
    - personnel_db
ports:
    - "5001:5001"
environment:
    - CONNECTION_STRING=${CONNECTION_STRING}
command: ["dotnet", "Personnel.Infrastructure.Migrator.dll", "${CONNECTION_STRING}"]
