# 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".添加IronPdf.Linux将包添加到您的解决方案中

增加内存和超时时间 - IronPDF 需要比 Lambda 的默认值更多的时间和内存。 这可以在
aws-lambda-tools-defaults.json中配置。 请调整此内容以匹配您的功能。在这个例子中。 我们将其设置为512(mb)和 330(秒):
"function-memory-size" : 512,
"function-timeout" : 330,也可以使用 Lambda 控制台更新配置，例如https://docs.aws.amazon.com/lambda/latest/dg/configuration-function-common.html#configuration-memory-console.
请按照以下文档的最后部分来发布和尝试一个 Lambda 函数。https://aws.amazon.com/blogs/developer/net-5-aws-lambda-support-with-container-images/
Lambda函数也可以使用Lambda控制台来调用，[https://console.aws.amazon.com/lambda 或通过 Visual Studio 调用 AWS 工具包 - 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)
如果您收到“GPU进程无法使用”的消息，则可能是安装时没有使用管理员权限运行。 请尝试使用管理员/根权限再次运行软件。 或者在您的 Docker 文件中添加以下内容：
- 运行 chmod 755 "runtimes/linux-x64/native/IronCefSubprocess"
