fn = nil

fn.add_alias("Live")

# Is equivalent to

Lambda::Alias.new(self, "AliasLive", {
    alias_name: "Live",
    version: fn.current_version,
})

    The environment variable's value.

  • options (AWSCDK::Lambda::EnvironmentOptions, nil) (defaults to: nil) —

    Environment variable options.

end

#apply_cross_stack_reference_strength(strength) ⇒ void

This method returns an undefined value.

Override the cross-stack reference strength for this resource.

When set, any cross-stack reference to this resource will use the specified mechanism instead of the global default determined by the @aws-cdk/core:defaultCrossStackReferences context key. This is useful for selectively weakening specific references to avoid the "deadly embrace" problem without changing the app-wide default.

  jsii_call_method("applyCrossStackReferenceStrength", [strength])
end

#apply_removal_policy(policy) ⇒ void

This method returns an undefined value.

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

#consider_warning_on_invoke_function_permissions(scope, action) ⇒ void

This method returns an undefined value.

A warning will be added to functions under the following conditions: - permissions that include lambda:InvokeFunction are added to the unqualified function.

  • function.currentVersion is invoked before or after the permission is created.

This applies only to permissions on Lambda functions, not versions or aliases. This function is overridden as a noOp for QualifiedFunctionBase.

end

#current_version ⇒ AWSCDK::Lambda::Version

Returns a lambda.Version which represents the current version of this Lambda function. A new version will be created every time the function's configuration changes.

end

#env ⇒ AWSCDK::Interfaces::ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed in a Stack (those created by creating new class instances like new Role(), new Bucket(), etc.), this is always the same as the environment of the stack they belong to.

For referenced resources (those obtained from referencing methods like Role.fromRoleArn(), Bucket.fromBucketName(), etc.), they might be different than the stack they were imported into.

Returns:

end

#get_resource_arn_attribute(arn_attr, arn_components) ⇒ String

Returns an environment-sensitive token that should be used for the resource's "ARN" attribute (e.g. bucket.bucketArn).

Normally, this token will resolve to arn_attr, but if the resource is referenced across environments, arn_components will be used to synthesize a concrete ARN with the resource's physical name. Make sure to reference this.physicalName in arn_components.

Parameters:

  • arn_attr (String) —

    The CFN attribute which resolves to the ARN of the resource.

  • arn_components (AWSCDK::ARNComponents) —

    The format of the ARN of this resource.

end

#get_resource_name_attribute(name_attr) ⇒ String

Returns an environment-sensitive token that should be used for the resource's "name" attribute (e.g. bucket.bucketName).

Normally, this token will resolve to name_attr, but if the resource is referenced across environments, it will be resolved to this.physicalName, which will be a concrete name.

Parameters:

  • name_attr (String) —

    The CFN attribute which resolves to the resource's name.

Returns:

  • (String)

#invalidate_version_based_on(x) ⇒ void

This method returns an undefined value.

Mix additional information into the hash of the Version object.

The Lambda Function construct does its best to automatically create a new Version when anything about the Function changes (its code, its layers, any of the other properties).

However, you can sometimes source information from places that the CDK cannot look into, like the deploy-time values of SSM parameters. In those cases, the CDK would not force the creation of a new Version object when it actually should.

This method can be used to invalidate the current Version object. Pass in any string into this method, and make sure the string changes when you know a new Version needs to be created.

This method may be called more than once.

Parameters:

  • x (String)

end

#is_bound_to_vpc ⇒ Boolean

If this is false, trying to access the connections object will fail.

Returns:

  • (Boolean)

  jsii_get_property("isBoundToVpc")
end

#latest_version ⇒ AWSCDK::Lambda::IVersion

The $LATEST version of this function.

Note that this is reference to a non-specific AWS Lambda version, which means the function this version refers to can return different results in different invocations.

To obtain a reference to an explicit version which references the current function configuration, use lambdaFunction.currentVersion instead.

Returns:



192
193

# File 'lambda_nodejs/nodejs_function.rb', line 192

def latest_version()
  jsii_get_property("latestVersion")
end

#log_group ⇒ AWSCDK::Logs::ILogGroup

The LogGroup where the Lambda function's logs are made available.

If either log_retention is set or this property is called, a CloudFormation custom resource is added to the stack that pre-creates the log group as part of the stack deployment, if it already doesn't exist, and sets the correct log retention period (never expire, by default).

Further, if the log group already exists and the log_retention is not set, the custom resource will reset the log retention to never expire even if it was configured with a different value.

Returns:
