1. 使用容器模板創建 AWS Lambda (.NET 5)
請參閱AWS官方文件的第一部分：.NET 5 AWS Lambda 支援容器映像文件.
2. 添加封裝相依性
這些依賴項是在此AWS環境中運行Chrome所必需的。
請根據以下說明修改 Docker 文件：
使用 .NET 5 的 AWS Lambda
AWS Lambda with .NET 7
AWS Lambda with .NET 8
3. Add the IronPDF (Linux) NuGet Package
Install IronPdf.Linux
- In Solution Explorer, right-click References, Manage NuGet Packages
- Select Browse and search
IronPdf.Linux - Select the package and install.
4. Modify FunctionHandler Code
This example will create a PDF file from a webpage IronPDF website and save it to /tmp. In order to view this PDF, you must upload it to another service such as S3.
It is necessary to configure the temporary folder when using IronPDF on AWS Lambda. Please use the TempFolderPath and CustomDeploymentDirectory properties to do this.
public Casing FunctionHandler(string input, ILambdaContext context)
{
try
{
context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}");
var awsTmpPath = @"/tmp/"; // AWS temporary storage
//[optional] enable logging (please uncomment these code if you face any problem)
//IronPdf.Logging.Logger.EnableDebugging = true;
//IronPdf.Logging.Logger.LogFilePath = awsTmpPath;
//IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;
//set your license key
IronPdf.License.LicenseKey = "YOUR_LICENSE_KEY";
//set ChromeGpuMode to Disabled
IronPdf.Installation.ChromeGpuMode = IronPdf.Engines.Chrome.ChromeGpuModes.Disabled;
//set IronPDF Temp Path
IronPdf.Installation.TempFolderPath = awsTmpPath;
IronPdf.Installation.CustomDeploymentDirectory = awsTmpPath;
//set auto LinuxAndDockerDependenciesAutoConfig
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;
context.Logger.LogLine($"creating IronPdf.ChromePdfRenderer");
var Renderer = new IronPdf.ChromePdfRenderer();
context.Logger.LogLine($"rendering Pdf");
using var pdfDoc = Renderer.RenderUrlAsPdf("https://ironpdf.com/");
var guid = Guid.NewGuid();
var fileName = $"/tmp/{input}_{guid}.pdf"; //save file to /tmp
context.Logger.LogLine($"saving pdf name : {fileName}");
pdfDoc.SaveAs(fileName);
//you can upload the saved PDF file to anywhere such as S3.
context.Logger.LogLine($"COMPLETE!");
}
catch (Exception e)
{
context.Logger.LogLine($"[ERROR] FunctionHandler : {e.Message}");
}
return new Casing(input?.ToLower(), input?.ToUpper());
}public Casing FunctionHandler(string input, ILambdaContext context)
{
try
{
context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}");
var awsTmpPath = @"/tmp/"; // AWS temporary storage
//[optional] enable logging (please uncomment these code if you face any problem)
//IronPdf.Logging.Logger.EnableDebugging = true;
//IronPdf.Logging.Logger.LogFilePath = awsTmpPath;
//IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;
//set your license key
IronPdf.License.LicenseKey = "YOUR_LICENSE_KEY";
//set ChromeGpuMode to Disabled
IronPdf.Installation.ChromeGpuMode = IronPdf.Engines.Chrome.ChromeGpuModes.Disabled;
//set IronPDF Temp Path
IronPdf.Installation.TempFolderPath = awsTmpPath;
IronPdf.Installation.CustomDeploymentDirectory = awsTmpPath;
//set auto LinuxAndDockerDependenciesAutoConfig
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

5. Increase Memory and Timeout
IronPDF requires more time and memory than the default value of Lambda. You can configure it in aws-lambda-tools-defaults.json. Please adjust this to match your function. In this example, we will set it to 512 (MB) and 330 (seconds).
"function-memory-size" : 512,
"function-timeout" : 330,You also can update this configuration using the Lambda console. Navigate to the AWS Lambda Memory Configuration Guide article for more information.
6. Publish
Please follow the instructions in the latter part of the '.NET 5 AWS Lambda Support with Container Images' document to publish and test your Lambda function.
7. Try it Out!
You can activate the Lambda function using the AWS Lambda Console or via Visual Studio by using the AWS Toolkit for Visual Studio.
