Instance Method Details
#add_layer_version_permission(params = {}) ⇒ Types::AddLayerVersionPermissionResponse
Adds permissions to the resource-based policy of a version of an Lambda layer. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.
To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.
422 423 424 425 |
# File 'gems/aws-sdk-lambda/lib/aws-sdk-lambda/client.rb', line 422 def (params = {}, = {}) req = build_request(:add_layer_version_permission, params) req.send_request() end |
#add_permission(params = {}) ⇒ Types::AddPermissionResponse
Grants an Amazon Web Services service, account, or organization permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. Note: Lambda does not support adding policies to version $LATEST.
To grant permission to another account, specify the account ID as the
Principal
. To grant permission to an organization defined in
Organizations, specify the organization ID as the PrincipalOrgID
.
For Amazon Web Services services, the principal is a domain-style
identifier defined by the service, like s3.amazonaws.com
or
sns.amazonaws.com
. For Amazon Web Services services, you can also
specify the ARN of the associated resource as the SourceArn
. If you
grant permission to a service principal without specifying the source,
other accounts could potentially configure resources in their account
to invoke your Lambda function.
This action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies.

#create_alias(params = {}) ⇒ Types::AliasConfiguration
Creates an alias for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.
You can also map an alias to split invocation requests between two
versions. Use the RoutingConfig
parameter to specify a second
version and the percentage of invocation requests that it receives.

# File 'gems/aws-sdk-lambda/lib/aws-sdk-lambda/client.rb', line 693 def create_code_signing_config(params = {}, = {}) req = build_request(:create_code_signing_config, params) req.send_request() end |
#create_event_source_mapping(params = {}) ⇒ Types::EventSourceMappingConfiguration
Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and triggers the function.
For details about how to configure different event sources, see the following topics.
The following error handling options are only available for stream sources (DynamoDB and Kinesis):
BisectBatchOnFunctionError
- If the function returns an error, split the batch in two and retry.DestinationConfig
- Send discarded records to an Amazon SQS queue or Amazon SNS topic.MaximumRecordAgeInSeconds
- Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expiresMaximumRetryAttempts
- Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.ParallelizationFactor
- Process multiple batches from each shard concurrently.
For information about which configuration parameters apply to each event source, see the following topics.

#create_function(params = {}) ⇒ Types::FunctionConfiguration
Creates a Lambda function. To create a function, you need a deployment package and an execution role. The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.
You set the package type to Image
if the deployment package is a
container image. For a container image, the code property must
include the URI of a container image in the Amazon ECR registry. You
do not need to specify the handler and runtime properties.
You set the package type to Zip
if the deployment package is a .zip
file archive. For a .zip file archive, the code property specifies
the location of the .zip file. You must also specify the handler and
runtime properties. The code in the deployment package must be
compatible with the target instruction set architecture of the
function (x86-64
or arm64
). If you do not specify the
architecture, the default value is x86-64
.
When you create a function, Lambda provisions an instance of the
function and its supporting resources. If your function connects to a
VPC, this process can take a minute or so. During this time, you
can't invoke or modify the function. The State
, StateReason
, and
StateReasonCode
fields in the response from GetFunctionConfiguration
indicate when the function is ready to invoke. For more information,
see Function States.
A function has an unpublished version, and can have published versions
and aliases. The unpublished version changes when you update your
function's code and configuration. A published version is a snapshot
of your function code and configuration that can't be changed. An
alias is a named resource that maps to a version, and can be changed
to map to a different version. Use the Publish
parameter to create
version 1
of your function from its initial configuration.
The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency).
You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set set of signing profiles, which define the trusted publishers for this function.
If another account or an Amazon Web Services service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.
To invoke your function directly, use Invoke. To invoke your function in response to events in other Amazon Web Services services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions.

#invoke(params = {}) ⇒ Types::InvocationResponse
Invokes a Lambda function. You can invoke a function synchronously
(and wait for the response), or asynchronously. To invoke a function
asynchronously, set InvocationType
to Event
.
For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace.
When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior.
For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue.
The status code in the API response doesn't reflect function errors.
Error codes are reserved for errors that prevent your function from
executing, such as permissions errors, limit errors, or issues
with your function's code and configuration. For example, Lambda
returns TooManyRequestsException
if executing the function would
cause you to exceed a concurrency limit at either the account level
(ConcurrentInvocationLimitExceeded
) or function level
(ReservedFunctionConcurrentInvocationLimitExceeded
).
For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.
This operation requires permission for the lambda:InvokeFunction action.

#put_function_concurrency(params = {}) ⇒ Types::Concurrency
Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.
Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.
Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Managing Concurrency.

#put_function_event_invoke_config(params = {}) ⇒ Types::FunctionEventInvokeConfig
Configures options for asynchronous invocation on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig.
By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.
To send an invocation record to a queue, topic, function, or event bus, specify a destination. You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

#update_event_source_mapping(params = {}) ⇒ Types::EventSourceMappingConfiguration
Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location.
For details about how to configure different event sources, see the following topics.
The following error handling options are only available for stream sources (DynamoDB and Kinesis):
BisectBatchOnFunctionError
- If the function returns an error, split the batch in two and retry.DestinationConfig
- Send discarded records to an Amazon SQS queue or Amazon SNS topic.MaximumRecordAgeInSeconds
- Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expiresMaximumRetryAttempts
- Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.ParallelizationFactor
- Process multiple batches from each shard concurrently.
For information about which configuration parameters apply to each event source, see the following topics.

#update_function_code(params = {}) ⇒ Types::FunctionConfiguration
Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing.
If the function's package type is Image
, you must specify the code
package in ImageUri
as the URI of a container image in the
Amazon ECR registry.
If the function's package type is Zip
, you must specify the
deployment package as a .zip file archive. Enter the Amazon S3
bucket and key of the code .zip file location. You can also provide
the function code inline using the ZipFile
field.
The code in the deployment package must be compatible with the target
instruction set architecture of the function (x86-64
or arm64
).
The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.

#update_function_configuration(params = {}) ⇒ Types::FunctionConfiguration
Modify the version-specific settings of a Lambda function.
When you update a function, Lambda provisions an instance of the
function and its supporting resources. If your function connects to a
VPC, this process can take a minute. During this time, you can't
modify the function, but you can still invoke it. The
LastUpdateStatus
, LastUpdateStatusReason
, and
LastUpdateStatusReasonCode
fields in the response from
GetFunctionConfiguration indicate when the update is complete and the
function is processing events with the new configuration. For more
information, see Function States.
These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.
To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an account or Amazon Web Services service, use AddPermission.

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean
Polls an API operation until a resource enters a desired state.
Basic Usage
A waiter will call an API operation until:
- It is successful
- It enters a terminal state
- It makes the maximum number of attempts
In between attempts, the waiter will sleep.
# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.
# poll for ~25 seconds
client.wait_until(waiter_name, params, {
max_attempts: 5,
delay: 5,
})
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(waiter_name, params, {
# disable max attempts
max_attempts: nil,
# poll for 1 hour, instead of a number of attempts
before_wait: -> (attempts, response) do
throw :failure if Time.now - started_at > 3600
end
})
Handling Errors
When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
Valid Waiters
The following table lists the valid waiter names, the operations they call,
and the default :delay
and :max_attempts
values.
waiter_name | params | :delay | :max_attempts |
---|---|---|---|
function_active | #get_function_configuration | 5 | 60 |
