# 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".- Add IronPdf.Linux package to your solution

/tmp. In order to view this PDF, it must be uploaded to another service, such as S3. (Official AWS example available here - https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/dotnetv3/S3/S3_Basics/S3_Basics.cs)

- Increase memory and timeout - IronPDF requires more time and memory than the default value of Lambda. This can be configured at
aws-lambda-tools-defaults.json. Please adjust this to match you function.
In this example. we set to 512 (mb) and 330 (seconds):
"function-memory-size" : 512,
"function-timeout" : 330,The configuration can also be updates using Lambda console - https://docs.aws.amazon.com/lambda/latest/dg/configuration-function-common.html#configuration-memory-console.
- Please follow the final part of the following documentation to publish and try a Lambda function https://aws.amazon.com/blogs/developer/net-5-aws-lambda-support-with-container-images/
- Lambda function can also be invoked using Lambda console, [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](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)
If you receive a "GPU process isn't usable" message, installation may not have been run with admin privileges. Please try running the software again with admin/root privileges. Alternatively add the following to your docker file:
- RUN chmod 755 "runtimes/linux-x64/native/IronCefSubprocess"
