Deploy the ssl-exporter helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `ssl-exporter` Helm chart on Kubernetes using Pulumi, you'll need to do the following:

1. Set up your Kubernetes cluster and ensure you have the necessary access to deploy resources to it.
2. Use the `@pulumi/kubernetes` package to interact with your Kubernetes cluster via Pulumi.
3. Use the `helm.v3.Chart` resource provided by the Pulumi Kubernetes provider to deploy the `ssl-exporter` Helm chart.

Below is a Pulumi program written in TypeScript that accomplishes the deployment of the `ssl-exporter` Helm chart. The program assumes you have configured your Pulumi environment to connect to your Kubernetes cluster.

First, you'll need to install the required packages using npm:

```bash
npm install @pulumi/pulumi @pulumi/kubernetes
```

Now, here's the Pulumi program:

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

// Define the deployment of the ssl-exporter Helm chart.
const sslExporterChart = new k8s.helm.v3.Chart("ssl-exporter", {
    // Specify the chart repository and name. For this example, we assume the ssl-exporter
    // is available in a chart repository that you have access to. Replace 'REPO_URL' with
    // the actual URL where the ssl-exporter chart can be found.
    repo: "REPO_URL",
    chart: "ssl-exporter",

// If required, you can specify the chart version and values for the chart. These values
    // will override defaults in the Helm chart's 'values.yaml' file.
    // In this example, the version is set to a placeholder value – use the actual version number as needed.
    // And the values below are purely for illustrative purposes; you should adjust them to fit your needs.
    values: {
        service: {
            type: "ClusterIP",
        },
    },
    // The namespace where you want to deploy the ssl-exporter chart. Change it if you want to deploy
    // to a different namespace.
    namespace: "monitoring",
    
    // You can also provide additional options, like settings for fetching the chart, or custom transformations.
    // These are optional and based on your specific requirements.
});

// Export the name of the chart deployment. This will output the name when the Pulumi program completes.
export const chartName = sslExporterChart.metadata.apply(metadata => metadata.name);
```

Explanation:
- We import the necessary `@pulumi/kubernetes` package to interact with our Kubernetes cluster.
- Using `new k8s.helm.v3.Chart`, we define the deployment of our Helm chart. This is a Pulumi resource for deploying Helm charts.
- We specify the required chart information such as the repository URL and the chart name. Replace `"REPO_URL"` with the actual repository URL hosting the `ssl-exporter` chart.
- Optional chart settings like version and values can be overridden. For example, the values are set for the service type to be `ClusterIP`. You may need to change these based on your chart's requirements.
- We specify the namespace where the `ssl-exporter` will be deployed. In this case, it's `"monitoring"`. You can change this to any namespace you have on your Kubernetes cluster.
- Finally, we export the name of the chart deployment as an output. After successfully running the Pulumi program, this will print the name of the Helm chart deployment we created.

Remember, before running this Pulumi program, make sure that you have access to your Kubernetes cluster, and your `kubeconfig` file is properly set up to interact with it. Also, replace the placeholder values like `"REPO_URL"` with actual values that fit your deployment scenario.
