Terraform cdk modules

Terraform CDK for Terraform
1

Hello,
I am trying to build reusable modules using terrafrom cdktf and each of them is a separate project (which means that each module needs terrafrom cdktf init to create it) .
So in order to achieve this i tried to build the module using npm run compile and then i included it in my package.json in my implementation .

But the wired thing is when i use DataSources or TerraformAssets in my modules i get unexpected error which :

    Error: No stack could be identified for the construct at path 'powershell_script'

This is my module :



export class LinuxBaseLineNodeModule extends Construct {
  public props: BaseLineNodeProps;
  constructor(scope: Construct, id: string, props: BaseLineNodeProps) {
    super(scope, id);
    this.props = props;
    let generic_tags = {
      environment: props.environment,
      product: props.product,
    };

    new AwsProvider(scope, "aws");    
    const ami = new DataAwsAmi(this, 'ami', {
      mostRecent: true,
      owners: ['amazon'],
      filter: [
        {
          name: 'name',
          values: [`amzn2-ami-hvm-*-x86_64-gp2`],
        },
      ],
    });
    const powershell = new TerraformAsset(scope, "powershell_script", {
      path: "./scripts/user-data.ps1",
      type: AssetType.FILE,
    });

    // Resources
    new Instance(scope, "instance", {
      ebsOptimized: true,
      ami: ami.arn,
      instanceType: "t2.micro",
      userData: Token.asString(
          Fn.file(powershell.path),
      ),
      tags: generic_tags,
    });
  }
}

Hi @ramzi-af :wave:

How are you using your LinuxBaseLineNodeModule construct in the project that consumes it? What are you passing as scope?

Hello @ansgarm , well for LinuxBaseLineNodeModule and our modules in general, which are a CDKTF projects, we compile them and publish them locally as Typescript packages, After that we reference them inside package.json file in our implementation.
These modules will then be available in our implementation.
