This library provides AWS CDK constructs for AWS Lambda functions written in Ruby.
import * as cdk from 'aws-cdk-lib';
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as lambdaRuby from 'cdk-lambda-ruby';
import { Construct } from 'constructs';
export class ExampleStack extends cdk.Stack {
public constructor(scope: Construct, id: string, props?: cdk.StackProps) {
super(scope, id, props);
new lambdaRuby.RubyFunction(this, 'MyFunction', {
runtime: lambda.Runtime.RUBY_3_2,
sourceDirectory: 'function',
handler: 'main.handler',
bundlerConfig: { // optional
without: 'development:test', // optional, default: 'development:test'
build: { // optional
'some-gem': '--some-build-option',
},
},
});
}
}RubyFunction deploys the sourceDirectory as a Lambda function written in Ruby. runtime is expected to be a Ruby-family Lambda Runtime (i.e., RUBY_3_2 at the moment).
If a file named "Gemfile" exists directly inside sourceDirectory, the dependency gems are bundled using Bundler. Bundling is performed inside a Docker container using the Lambda builder images privided by AWS. The bundlerConfig prop may have the without field to specify a colon-separated list of gem groups to skip installation.
RubyFunction also accepts common FunctionOptions.
The library caches downloaded gems, compiled extensions, and installation trees under "cdk.out/.cache" to optimize synthesis speed. Try delete these files if something unexpected happens.
