Returns a list of Lambda functions, with the version-specific configuration of each¶

Description¶

Returns a list of Lambda functions, with the version-specific configuration of each. Lambda returns up to 50 functions per call.

Set FunctionVersion to ALL to include all published versions of each function in addition to the unpublished version.

The list_functions operation returns a subset of the FunctionConfiguration fields. To get the additional fields (State, StateReasonCode, StateReason, LastUpdateStatus, LastUpdateStatusReason, LastUpdateStatusReasonCode, RuntimeVersionConfig) for a function or version, use get_function.

Usage¶

lambda_list_functions(MasterRegion, FunctionVersion, Marker, MaxItems)

Arguments¶

MasterRegion

For Lambda@Edge functions, the Amazon Web Services Region of the master function. For example, us-east-1 filters the list of functions to include only Lambda@Edge functions replicated from a master function in US East (N. Virginia). If specified, you must set FunctionVersion to ALL.
FunctionVersion

Set to ALL to include entries for all published versions of each function.
Marker

Specify the pagination token that's returned by a previous request to retrieve the next page of results.
MaxItems

The maximum number of functions to return in the response. Note that list_functions returns a maximum of 50 items in each response, even if you set the number higher.
