如何在 Windows 虚拟机 ec2 aws 中运行 .NET 应用程序？

Question

我有一个关于如何使用打包程序在 Windows 虚拟机中运行 .NET 应用程序（一个简单的服务器）的问题。

这是我的配置： 这是为虚拟机安装所有必需依赖项的脚本：

# Install .NET Core Runtime
Invoke-WebRequest -Uri https://dot.net/v1/dotnet-install.ps1 -OutFile dotnet-install.ps1
.\dotnet-install.ps1 -Channel 8.0 -Runtime aspNetCore

Invoke-WebRequest -Uri https://dot.net/v1/dotnet-install.ps1 -OutFile dotnet-install.ps1
.\dotnet-install.ps1 -Channel 8.0
Remove-Item dotnet-install.ps1

# Check .NET is installed
(Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full').Version

# Set PATH environment variable to include dotnet directory
[System.Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Users\Administrator\AppData\Local\Microsoft\dotnet\", [EnvironmentVariableTarget]::Machine)


# Install Git
Invoke-WebRequest -Uri https://github.com/git-for-windows/git/releases/download/v2.35.1.windows.1/Git-2.35.1-64-bit.exe -OutFile Git-2.35.1-64-bit.exe
Start-Process -FilePath Git-2.35.1-64-bit.exe -ArgumentList "/SILENT" -Wait 
Remove-Item Git-2.35.1-64-bit.exe

# Set PATH environment variable to include Git directory
[System.Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Program Files\Git\bin\;C:\Program Files\Git\cmd\", [EnvironmentVariableTarget]::Machine)

# Install IIS (Internet Information Services) if not already installed
Install-WindowsFeature -Name Web-Server -IncludeManagementTools

# Install Web Management Service
Install-WindowsFeature -Name Web-Mgmt-Service 

这是在虚拟机内构建 .NET 应用程序的第二个脚本

# Define the directory where you want to clone the application
$cloneDirectory = "C:\DotNetApp"
$iisDirectory = "C:\WebApiDeployed"

# Create the directory if it doesn't exist
if (-not (Test-Path -Path $cloneDirectory -PathType Container)) {
    New-Item -Path $cloneDirectory -ItemType Directory
}

# Create the directory if it doesn't exist
if (-not (Test-Path -Path $iisDirectory -PathType Container)) {
    New-Item -Path $iisDirectory -ItemType Directory
}

# Clone the application from GitHub
git clone https://github.com/biancapistea/webApi.git $cloneDirectory

# Navigate to the cloned directory
Set-Location $cloneDirectory

# Build the application
dotnet build

Copy-Item -Path "$cloneDirectory\bin\Debug\net8.0\*" -Destination $iisDirectory -Recurse

New-WebSite -Name "webApi" -PhysicalPath $iisDirectory -Port 80 -HostHeader "localhost"

# Run the application
# dotnet run

这是我的打包文件： 此版本在 Windows Server 之上构建映像并仅安装必要的依赖项：

packer {
  required_plugins {
    amazon = {
      source  = "github.com/hashicorp/amazon"
      version = "~> 1"
    }
  }
}

variable "aws_access_key" {
  type    = string
  default = "${env("AWS_ACCESS_KEY_ID")}"
}

variable "aws_secret_access_key" {
  type    = string
  default = "${env("AWS_SECRET_ACCESS_KEY")}"
}

variable "aws_region" {
  type    = string
  default = "${env("AWS_REGION")}"
}

# "timestamp" template function replacement
locals { timestamp = regex_replace(timestamp(), "[- TZ:]", "") }

source "amazon-ebs" "autogenerated_1" {
  ami_name      = "packer prerequisites ${local.timestamp}"
  instance_type = "t2.micro"
  source_ami    = "ami-0381840963c35cb1f"

  access_key    = var.aws_access_key
  secret_key    = var.aws_secret_access_key
  region        = var.aws_region
  communicator = "winrm"
  user_data_file = "./bootstrap_win.txt"
  winrm_password = "SuperS3cr3t!!!!"
  winrm_username  = "Administrator"
}

build {
  sources = ["source.amazon-ebs.autogenerated_1"]

  provisioner "powershell" {
    script = "./prerequisites.ps1"
  }

  post-processor "manifest" {
    output = "prerequisites_ami.json"
    strip_path = true
  }
}

第二个在 AWS 上基于之前创建的已安装依赖项的映像构建映像。

packer {
  required_plugins {
    // amazon = {
    //   source  = "github.com/hashicorp/amazon"
    //   version = "~> 1"
    // }
  }
}

variable "aws_access_key_app" {
  type    = string
  default = "${env("AWS_ACCESS_KEY_ID")}"
}

variable "aws_secret_access_key_app" {
  type    = string
  default = "${env("AWS_SECRET_ACCESS_KEY")}"
}

variable "aws_region_app" {
  type    = string
  default = "${env("AWS_REGION")}"
}

variable "prerequisites_ami" {
  type    = string
  default = "ami-0d0f70de1aeb0ce6"
}

# "timestamp" template function replacement
locals { timestamp = regex_replace(timestamp(), "[- TZ:]", "") }

source "amazon-ebs" "autogenerated_1" {
  ami_name      = "packer application ${local.timestamp}"
  instance_type = "t2.micro"
  source_ami    = var.prerequisites_ami #id of the windows-prerequisites image generated by me

  access_key    = var.aws_access_key_app
  secret_key    = var.aws_secret_access_key_app
  region        = var.aws_region_app
  communicator = "winrm"
  user_data_file = "./bootstrap_win.txt"
  winrm_password = "SuperS3cr3t!!!!"
  winrm_username  = "Administrator"

}

build {
  sources = ["source.amazon-ebs.autogenerated_1"]

    provisioner "powershell" {
    script = "./application.ps1"
  }
}

现在，当我使用 terraform 在 AWS 上创建负载均衡器时（我使用之前创建的映像 AMI，其中包含安装和我的 .NET 应用程序），我尝试访问 DNS，但我只看到 Windows 服务器默认网站，而不是我的.NET 应用程序。这是链接：aws-alb-1335693886.eu-central-1.elb.amazonaws.com。

可能是什么问题？如何在图像内运行 .NET 应用程序，以便当我单击此链接时：aws-alb-1335693886.eu-central-1.elb.amazonaws.com 它将显示我的 .NET 应用程序？

PS：我对 DevOps 很陌生。谢谢您的帮助！

如果你先用docker打包你的应用程序会更好。使用虚拟机中的映像来启动应用程序。

应该可以。
