AWS CDK Support

[dbettin]

Is this runtime supported in the CDK? If not, is this a possibility?

What problem are you trying to solve?

[dbettin]

We would like to use the CDK to deploy our aws assets as code as compared to serverless or SAML.

Currently, it seems like custom runtimes are not supported when creating lambdas via the CDK.

This might be a better issue for the CDK team, but I wanted to start here first.

@dbettin This is more of a CDK-related question, but my glance at the documentation makes me inclined to say no—CloudFormation should provide those hooks, but I can't find any mention of “provided runtimes” in CloudFormation or the CDK, which is odd. I'd suggest opening an issue on their repository.

[dbettin]

Will do, thanks.

@dbettin Having looked more closely at their source, you might be able to use this runtime in the CDK via:

new Runtime('Rust')

After all, Lambda expects just a ZIP file and the Ruby25 runtime is technically a provided runtime.

(But I'd confirm with the CDK team first.)

[dbettin]

Awesome! I completely overlooked that comment when I took a look at that piece of code. I will confirm with the team.

Thanks!

FYI - the implemented the feature already. aws/aws-cdk#1761

[davidbarsky]

@dbettin Great to hear! We should have an example with the CDK somewhere, maybe.

[happyspace]

Just to be clear the solution mentioned above aws/aws-cdk#1761 by @dbettin

    const rustFun = new lambda.Function(this, 'rust-hello', {
      code: lambda.Code.fromAsset('lambdas//lambdas.zip'),
      runtime: Runtime.PROVIDED_AL2,
      handler: 'doesnt.matter',
      timeout: Duration.seconds(30),
      memorySize: 1024,
      environment: {
        "RUST_BACKTRACE": '1',
      },
    });

Provided_AL2 = Amazon Linux 2
