AWS-Anweisungen

  1. Siehehttps://aws.amazon.com/blogs/developer/net-5-aws-lambda-support-with-container-images/

  2. Erstellen und verwenden Sie das folgende Dockerfile:

    # This COPY command copies the .NET Lambda project's build artifacts from the host machine into the image.
    # The source of the COPY should match where the .NET Lambda project publishes its build artifacts. If the Lambda function is being built
    # with the AWS .NET Lambda Tooling, the `--docker-host-build-output-dir` switch controls where the .NET Lambda project
    # will be built. The .NET Lambda project templates default to having `--docker-host-build-output-dir`
    # set in the aws-lambda-tools-defaults.json file to "bin/Release/lambda-publish".
    #
    # Alternatively Docker multi-stage build could be used to build the .NET Lambda project inside the image.
    # For more information on this approach checkout the project's README.md file.
    COPY "bin/Release/lambda-publish".

  2. Ändern Sie _FunctionHandler _code - in diesem Beispiel wird ein PDF aus einer Webseite erstellt(https://ironpdf.com/) und in /tmp speichern. Um diese PDF-Datei anzeigen zu können, muss sie auf einen anderen Dienst, z. B. S3, hochgeladen werden.(Offizielles AWS-Beispiel hier verfügbar -https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/dotnetv3/S3/S3_Basics/S3_Basics.cs)

  1. Erhöhen Sie Speicher und Timeout - IronPDF benötigt mehr Zeit und Speicher als der Standardwert von Lambda. Dies kann in aws-lambda-tools-defaults.json konfiguriert werden. Bitte passen Sie dies an Ihre Funktion an.

    In diesem Beispiel. wir setzen auf 512(mb) und 330(sekunden):

    "function-memory-size" : 512,
        "function-timeout"     : 330,

Die Konfiguration kann auch über die Lambda-Konsole aktualisiert werdenhttps://docs.aws.amazon.com/lambda/latest/dg/configuration-function-common.html#configuration-memory-console.

  1. Bitte folgen Sie dem letzten Teil der folgenden Dokumentation, um eine Lambda-Funktion zu veröffentlichen und zu testenhttps://aws.amazon.com/blogs/developer/net-5-aws-lambda-support-with-container-images/

  2. Lambda-Funktionen können auch über die Lambda-Konsole aufgerufen werden,[https://console.aws.amazon.com/lambda oder über Visual Studio mit dem AWS Toolkit für Visual Studio aufgerufen werden - https://docs.aws.amazon.com/toolkit-for-visual-studio/latest/user-guide/lambda-creating-project-in-visual-studio.html](https://console.aws.amazon.com/lambda> or invoked 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)

    Wenn Sie die Meldung "GPU process isn't usable" erhalten, wurde die Installation möglicherweise nicht mit Administratorrechten ausgeführt. Bitte versuchen Sie, die Software erneut mit Administrator-/Root-Rechten auszuführen. Alternativ können Sie auch Folgendes zu Ihrer Docker-Datei hinzufügen:

  • RUN chmod 755 "runtimes/linux-x64/native/IronCefSubprocess"
