How to upload Helm chart to GCP with Pulumi?

You can use the Pulumi Kubernetes provider to deploy a Helm chart to a Kubernetes cluster on Google Cloud Platform (GCP). Here's a code that creates a Kubernetes Namespace and deploys a sample Nginx chart from the Bitnami Helm repository.

Firstly, create a Kubernetes namespace where the Helm chart will be deployed:

import * as k8s from "@pulumi/kubernetes";

const namespace = new k8s.core.v1.Namespace("test-namespace", {});

Then deploy the Helm chart:

import * as k8s from "@pulumi/kubernetes";

const nginx = new k8s.helm.v3.Chart("nginx", {
    repo: "bitnami",
    chart: "nginx",
    version: "9.3.2",
    namespace: namespace.metadata.name,
});

• The resources above use the Kubernetes and Helm providers to deploy Helm charts.
• We are creating a new namespace with k8s.core.v1.Namespace that will be used to scope our nginx deployment.
• Then, we are deploying an nginx Helm chart using new k8s.helm.v3.Chart. We specify bitnami as the repository, nginx as the chart, and 9.3.2 as the version.

Lastly, export the desired outputs:

import * as pulumi from "@pulumi/pulumi";

export const namespaceName = namespace.metadata.name;
export const nginxVersion = pulumi.output("9.3.2");

For complete Pulumi code:

import * as k8s from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";

// Create a Namespace
const namespace = new k8s.core.v1.Namespace("test-namespace", {});

// Deploy the Helm chart
const nginx = new k8s.helm.v3.Chart("nginx", {
    repo: "bitnami",
    chart: "nginx",
    version: "9.3.2",
    namespace: namespace.metadata.name,
});

// Export the Namespace name
export const namespaceName = namespace.metadata.name;
export const nginxVersion = pulumi.output("9.3.2");

Please note that you need to have a GCP Kubernetes cluster in place and setup kubeconfig correctly for your Pulumi package to have the right access for deployment.
