Deploy the stakater-create-environment helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `stakater-create-environment` Helm chart on Kubernetes using Pulumi, we will use the `Chart` resource from the Pulumi Kubernetes provider. This resource allows you to apply Helm charts to your Kubernetes cluster. To begin, you'll need to have Pulumi installed, along with the necessary cloud provider CLI configured for your Kubernetes cluster (in this case, typically `kubectl`).

Here's a step-by-step guide on how to accomplish this deployment:

1. **Setup Your Project**: Initialize a new Pulumi project using the CLI command `pulumi new typescript`.
   
2. **Install Pulumi Kubernetes SDK**: Add the Pulumi Kubernetes package by running `npm install @pulumi/kubernetes`.

3. **Write Your Pulumi Code**: In your `index.ts` file, write the TypeScript code using the `Chart` resource.

4. **Deploy**: Run `pulumi up` in your terminal to launch the deployment.

Below is the TypeScript code to deploy the `stakater-create-environment` helm chart. This example assumes that you already have a Kubernetes cluster up and running and that you've configured Pulumi to use the correct Kubernetes context.

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

// Define the settings for the Helm release.
const chartName = "stakater-create-environment";
const releaseName = "stakater-env-release";
const namespace = "default"; // Replace with your namespace if different
const chartVersion = "1.0.0"; // Specify the chart version you want to deploy
const repo = "stakater"; // The name of the Helm repository, change if needed

// Create a new Helm Chart resource that deploys the `stakater-create-environment` chart.
const stakaterEnvChart = new k8s.helm.sh.v3.Chart(releaseName, {
    namespace: namespace,
    chart: chartName,
    version: chartVersion,
    fetchOpts: {
        // Specify the repository where the chart is located if it's not in the default Helm repo
        repo: `https://charts.stakater.com`, // Replace with the actual repository URL
    },
    // Optionally, specify the values you want to override in the chart.
    // The following are placeholder values; you should use the actual values required by the chart.
    values: {
        serviceName: "example-service",
        servicePort: 80,
    },
}, { provider: k8sProvider }); // Ensure you create and pass the k8s provider if needed

// To create a provider, you typically do the following. Uncomment and adjust as necessary:
// const k8sProvider = new k8s.Provider("k8s-provider", {
//     kubeconfig: "<YOUR_KUBECONFIG_CONTENT>", // Replace or use the default context if already configured
// });

// Now, the `stakaterEnvChart` holds a reference to the deployed chart, and you can access its outputs if the chart provides any.

// For example, if the chart exposes an endpoint, you can export it:
// export const endpoint = stakaterEnvChart.getResourceProperty("v1/Service", "my-service", "status", "loadBalancer", "ingress", 0, "hostname");

```

This Pulumi program performs the following:
- Import the Pulumi Kubernetes package.
- Set parameters such as the chart name, release name, and namespace.
- Use the `Chart` resource to deploy the specified Helm chart to your Kubernetes cluster.
  
Remember to uncomment and configure the provider if your setup requires a specific kubeconfig.

Once you run `pulumi up`, Pulumi performs a deployment according to the plan it prints out for your confirmation. Keep an eye on your terminal for any prompts from Pulumi which may require your input to proceed.

If the Helm chart you want to deploy has additional configuration parameters, or you want to specify values for existing parameters, you can do that through the `values` property of the `Chart` resource. Check the documentation for the `stakater-create-environment` Helm chart for details on available configurations.

After running `pulumi up`, you can use the `kubectl get` command to verify the deployment, services, and any other resources created by the Helm chart in your cluster.
