Using IronPdf to create PDF files on AWS Lambda

1. Create AWS Lambda with a container template (.NET 5)

Please refer to the first part of this official document from AWS: https://aws.amazon.com/blogs/developer/net-5-aws-lambda-support-with-container-images/

2. Add package dependencies

These dependencies are required for Chrome in this AWS environment.

Please modify the Docker file according to these instructions:

3. Add the IronPDF (Linux) NuGet package

Install IronPdf.Linux

  1. In Solution Explorer, right-click References, Manage NuGet Packages
  2. Select Browse and search IronPdf.Linux
  3. Select the package and install.

4. Modify FunctionHandler code

This example will create a pdf file from a webpage https://ironpdf.com/ and save to /tmp . In order to view this pdf you must upload this pdf to another service such as S3.

        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
                Environment.SetEnvironmentVariable("TEMP", awsTmpPath, EnvironmentVariableTarget.Process);
                Environment.SetEnvironmentVariable("TMP", awsTmpPath, EnvironmentVariableTarget.Process);
                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);

                //here you can upload 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());
        }
    }

                //IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

                //set your license key

5. Increase Memory and Timeout

IronPdf requires more time and memory than the default value of Lambda. You can configure it at 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,
    "function-memory-size" : 512, 
    "function-timeout"     : 330,
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'"function-memory-size" : 512, "function-timeout" : 330,
VB   C#

You also can update this configuration using the Lambda console. https://docs.aws.amazon.com/lambda/latest/dg/configuration-function-common.html#configuration-memory-console

6. Publish

Please follow the instructions in the latter part of this document to publish and test your Lambda function. https://aws.amazon.com/blogs/developer/net-5-aws-lambda-support-with-container-images/

7. Try it out!

You can activate the Lambda function using the Lambda console https://console.aws.amazon.com/lambda or via Visual Studio by using the AWS Toolkit for Visual Studio. https://docs.aws.amazon.com/toolkit-for-visual-studio/latest/user-guide/lambda-creating-project-in-visual-studio.html
