Deploy the google-tag-manager helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `google-tag-manager` Helm chart on Kubernetes using Pulumi, you can use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows you to install, manage, and operate Helm charts in your Kubernetes cluster directly from your Pulumi program.

Below, I provide a Pulumi program in TypeScript that demonstrates how to deploy the `google-tag-manager` Helm chart. Before you deploy, ensure that you have installed Pulumi and configured it to communicate with your Kubernetes cluster.

First, you'll need the `@pulumi/kubernetes` npm package, which you can install with this command:

```shell
npm install @pulumi/kubernetes
```

Make sure you've also configured Pulumi with your Kubernetes cluster. Typically, Pulumi uses the Kubernetes configuration file (`kubeconfig`) to communicate with your cluster, just like the `kubectl` command-line tool.

Now, let's write the Pulumi program:

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

// Create a new Helm Chart resource that installs the google-tag-manager chart.
// You will need to specify the repository where the chart is located by providing
// the `repo` property for accurate installation.
const googleTagManagerChart = new kubernetes.helm.v3.Chart("google-tag-manager", {
    chart: "google-tag-manager",
    // If the chart is not part of the official Helm stable repository,
    // specify the repository URL where the chart can be found.
    // For example: repo: "https://charts.yourcompany.com/"
    // If your chart is in a public repository, uncomment the following line and update the URL.
    // repo: "https://your-repo-url/",
    version: "1.0.0",  // Specify the chart version you want to deploy.
    values: {
        // Provide the necessary values for your chart. This will depend on the chart you're deploying.
        // Refer to the chart's values.yaml file to find out what options you can configure.
    },
    namespace: "default", // Specify the Kubernetes namespace where to deploy the chart, e.g., "default".
});

// Export the base URL where the service is running (if applicable)
export const baseUrl = googleTagManagerChart.getResourceProperty("v1/Service", "google-tag-manager", "status").apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);
```

In this program, we create an instance of the `Chart` resource which represents the Helm chart for Google Tag Manager. We specify the `chart` name and the `version`. Additionally, you would have to provide the `values` which are the configuration values that tailor the Helm chart to your needs; these can include things like resource constraints, service types, and any other custom settings the chart supports. You can find these configurations in the `values.yaml` file of the Helm chart you wish to install. Note: Replace the placeholder for `repo` with the actual repository URL if the chart is not available in the default Helm chart repository.

Once the Pulumi program runs, it will use Helm to deploy `google-tag-manager` into the specified namespace on your Kubernetes cluster. The export statement at the bottom of the program may be used to output the base URL where the deployed service can be accessed, though this assumes the service exposes an external endpoint which may not apply to all charts.

To apply this Pulumi program, save the code to a file (for example, `index.ts`), and run the following commands in the same directory as your file:

```shell
pulumi up
```

This will initiate the deployment process. Pulumi will provide you with a preview of the changes and prompt for confirmation before proceeding with the actual deployment. After confirming, Pulumi will apply the Helm chart to the cluster.

Remember, this is a generic structure to install a Helm chart, and the availability of `google-tag-manager` as a Helm chart and the required values to configure it would depend on the actual Helm repository and the chart itself. If `google-tag-manager` is a placeholder for an internal or custom Helm chart, replace it with the actual chart name and repository information.
