Tutorial - Lambda with CLI
Note On Windows, some Bash CLI commands that you commonly use with Lambda (such as
zip
) are not supported by the operating system's built-in terminals. To get a Windows-integrated version of Ubuntu and Bash, install the Windows Subsystem for Linux.
Networking
Tip If your function already includes a VPC configuration from a previous API request, you can send an
UpdateFunctionConfiguration
request without the VPC configuration.Note Several AWS services offer VPC endpoints. You can use VPC endpoints to connect to AWS services from within a VPC without internet access.
Interface VPC endpoints
Note You need to include both the qualified and the unqualified function ARN in the resource.
File system
Note When you create a file system, you choose a performance mode that can't be changed later. General purpose mode has lower latency, and Max I/O mode supports a higher maximum throughput and IOPS. For help choosing, see Amazon EFS performance in the Amazon Elastic File System User Guide.
Note If your function is not already connected to a VPC, see Configuring a Lambda function to access resources in a VPC.
Code signing
Note Functions defined as container images do not support code signing.
Using layers
Note Make sure that the layers that you add to a function are compatible with the runtime and instruction set architecture of the function.
