Deploy the k8s-envoy-sidecar helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying a Helm chart on a Kubernetes cluster with Pulumi is relatively straightforward. In this case, we'll deploy the `k8s-envoy-sidecar` Helm chart, which is presumably a chart for deploying an Envoy proxy as a sidecar container in your Kubernetes pods. If the Helm chart `k8s-envoy-sidecar` doesn't actually exist, you would replace it with the correct name of the chart you wish to deploy.

Pulumi allows you to manage your cloud infrastructure using familiar programming languages. The `@pulumi/kubernetes` package can be used to deploy Helm charts with Pulumi using TypeScript, a superset of JavaScript.

Here's how you can do it:

1. First, define the Helm chart you want to deploy by creating a new `Chart` resource in your Pulumi program.

2. In the `Chart` resource, you'll need to specify the `chart` name, the `version` (if you have a specific one in mind), and also the `values` which are customization options for the Helm chart.

Below is a TypeScript program that you can use to deploy the `k8s-envoy-sidecar` Helm chart on Kubernetes using Pulumi. Please ensure that you have a Kubernetes cluster up and running, and your `kubeconfig` file is set up correctly to interact with your cluster.

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

// Create a new instance of the k8s-envoy-sidecar Helm Chart
const envoySidecarChart = new k8s.helm.v3.Chart("k8s-envoy-sidecar", {
    chart: "k8s-envoy-sidecar", // The name of the Helm chart. Ensure this is correct.
    version: "0.1.0", // Replace with your desired chart version.
    // Optionally, you can provide custom values to the Helm chart.
    values: {
        // Place the custom values for your Envoy sidecar chart here.
        // For example, if you need to set a specific log level, you might do:
        // logLevel: "debug"
    },
});

// Export any necessary output that might be useful
export const chartName = envoySidecarChart.metadata.name;

```

In the above TypeScript program:

- We import the Pulumi Kubernetes provider.
- We use the `Chart` class from the `@pulumi/kubernetes/helm/v3` module to create a new Helm chart instance.
- We pass an object to the `Chart` constructor that includes the chart name and version.
- You can replace the `version` property with the desired version of the `k8s-envoy-sidecar` Helm chart you want to deploy.
- In the `values` object, you can specify any custom values that are specific to the `k8s-envoy-sidecar` chart. These values override the defaults set by the Helm chart.

Remember that before running this Pulumi program, you should have the Pulumi CLI installed and configured with the appropriate access tokens or configuration for your cloud provider. Also, make sure your Kubernetes cluster is configured in your local environment, so Pulumi can interact with it using your `kubeconfig` file.

Once you've created a new TypeScript file with the content above, you can use the Pulumi CLI to deploy the Helm chart to your Kubernetes cluster:

```shell
pulumi up
```

This command will prompt you to confirm the deployment after showing you a preview. Upon confirmation, Pulumi will proceed with the deployment of the specified `k8s-envoy-sidecar` Helm chart.
