Wing

This block type is backed by Wing for Kubernetes and uses CDK8s to synthesize Kubernetes manifests from Wing classes.

Block Manifest

The kblock.yaml file defines the block manifest, containing block definitions like names, icons, description and optional operator environment settings.

Input Schema

The input schema is automatically derived from the Wing struct named <Kind>Spec. For example, if your resource kind is Bing, the CLI looks for a struct named BingSpec.

The KBLOCKS_SYSTEM_ID environment variable contains the Kblocks system name.

Implementation

Wing source code (.w files) should be placed under src/ and must include a public class named after the resource "kind":

pub struct BingSpec {
  myInput: str;
}

pub class Bing {
  new(spec: BingSpec) {
    // implementation goes here...
  }
}

Dependencies

The engine runs npm install from src/. You can install any Wing-compatible dependencies via npm. Note that @winglibs/k8s is required by the engine.

Outputs

Outputs specified in kblock.yaml must have corresponding public fields in your class:

pub class Bing {
  pub myOutput: str;

  new() {
    this.myOutput = "hello"
  }
}
