A pure CDK for Terraform construct to authenticate against Google Kubernetes Engine (GKE) without the need of any Terraform module

cdktf-gke-auth

Easily authenticate against a Google Kubernetes Engine (GKE) within your CDK for Terraform stack. Without the need to resort to Google's terraform GKE auth module. You can avoid running cdktf get as pre-synth step.

This project uses projen and jsii to compile the construct to Typescript, Python, Go and .Net (Java upon request).

Example usage (Typescript)

Install the construct with: yarn install cdktf-gke-auth.

import { GoogleProvider } from "@cdktf/provider-google/lib/provider";
import { TerraformOutput, TerraformStack } from "cdktf";
import { Construct } from "constructs";
import { GKEAuth } from 'cdktf-gke-auth';

export class MyKubeStack extends TerraformStack {
  constructor(scope: Construct, name: string) {
    super(scope, name);

    new GoogleProvider(this, "google-provider", {});

    const auth = new GKEAuth(this, "gke-auth", {
      clusterName: "my-cluster",
      location: "europe-west1",
      projectId: "my-project",
    });

    // init the Kubernetes provider like so:
    new KubernetesProvider(this, "kubernetes", {
      ...auth.authCredentials
    });

    // Or a helm provider like so:
     new HelmProvider(this, "helm", {
      kubernetes: auth.authCredentials,
    });
  }
}

The GKEAuth instance expose host, clusterCaCertificate, clusterCaCertificatePEM, and token you can use to authenticate using any of the kubernetes popular cdktf providers.
