Properties
The instruction set architecture that the function supports. Enter a string array with one of the valid values (arm64 or x86_64). The default value is `x86_64`.
The code for the function. You can define your function code in multiple ways:
To enable code signing for this function, specify the ARN of a code-signing configuration. A code-signing configuration includes a set of signing profiles, which define the trusted publishers for this function.
A dead-letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead-letter queues.
A description of the function.
Environment variables that are accessible from function code during execution.
The size of the function's `/tmp` directory in MB. The default value is 512, but it can be any whole number between 512 and 10,240 MB.
Connection settings for an Amazon EFS file system. To connect a function to a file system, a mount target must be available in every Availability Zone that your function connects to. If your template contains an AWS::EFS::MountTarget resource, you must also specify a `DependsOn` attribute to ensure that the mount target is created or updated before the function. For more information about using the `DependsOn` attribute, see DependsOn Attribute.
The name of the method within your code that Lambda calls to run your function. Handler is required if the deployment package is a .zip file archive. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Lambda programming model.
Configuration values that override the container image Dockerfile settings. For more information, see Container image settings.
A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.
The function's Amazon CloudWatch Logs configuration settings.
The amount of memory available to the function at runtime. Increasing the function memory also increases its CPU allocation. The default value is 128 MB. The value can be any multiple of 1 MB. Note that new AWS accounts have reduced concurrency and memory quotas. AWS raises these quotas automatically based on your usage. You can also request a quota increase.
The status of your function's recursive loop detection configuration. When this value is set to `Allow`and Lambda detects your function being invoked as part of a recursive loop, it doesn't take any action. When this value is set to `Terminate` and Lambda detects your function being invoked as part of a recursive loop, it stops your function being invoked and notifies you.
The number of simultaneous executions to reserve for the function.
The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image. The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation. For a list of all currently supported runtimes, see Supported runtimes.
Sets the runtime management configuration for a function's version. For more information, see Runtime updates.
A list of tags to apply to the function. You must have the `lambda:TagResource`, `lambda:UntagResource`, and `lambda:ListTags` permissions for your principal to manage the CFN stack. If you don't have these permissions, there might be unexpected behavior with stack-level tags propagating to the resource during resource creation and update.
The amount of time (in seconds) that Lambda allows a function to run before stopping it. The default is 3 seconds. The maximum allowed value is 900 seconds. For more information, see Lambda execution environment.
Set `Mode` to `Active` to sample and trace a subset of incoming requests with X-Ray.
For network connectivity to AWS resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can access resources and the internet only through that VPC. For more information, see Configuring a Lambda function to access resources in a VPC.
