Deploy the google-tag-manager helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Google Tag Manager Helm chart on AWS EKS, you'll need to set up an EKS cluster and configure Helm to deploy the chart onto it. Below is a step-by-step guide followed by a Pulumi TypeScript program to set up an EKS cluster and prepare it for the Helm deployment.

### Step-by-Step Guide:
1. **Set up an EKS Cluster**: Use the Pulumi EKS package to create a new EKS cluster.
2. **Install Helm on the Local Machine**: Helm is a package manager for Kubernetes, which you'll need to install the Google Tag Manager chart. Helm must be installed on your local machine where you're running Pulumi from.
3. **Add the Google Tag Manager Helm Chart Repository**: Before you can install a chart, you need to add the repository where the chart is located.
4. **Install the Helm Chart**: Deploy the Helm chart onto your EKS cluster.

### Pulumi Program to Set Up EKS Cluster:
```typescript
import * as aws from "@pulumi/aws";
import * as pulumi from "@pulumi/pulumi";
import * as eks from "@pulumi/eks";
import * as k8s from "@pulumi/kubernetes";

// Create an EKS cluster with the default configuration.
const cluster = new eks.Cluster("my-cluster");

// Export the cluster kubeconfig.
export const kubeconfig = cluster.kubeconfig;

// Create a Kubernetes provider instance that uses our cluster from above.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

```

### Instructions After Pulumi Program Execution:
After running the above Pulumi program to set up your EKS cluster, follow these steps on your local machine:

1. **Install Helm**:
    - On macOS: `brew install helm`
    - On Linux: `curl https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash`
    - On Windows: `choco install kubernetes-helm`

2. **Configure Helm with the EKS Cluster**: Point Helm to your EKS cluster by using the outputted kubeconfig from the Pulumi program.

3. **Add Helm Chart Repository**:
    ```shell
    helm repo add my-repo <url_to_your_google_tag_manager_helm_chart_repository>
    ```

4. **Update Helm Repositories**:
    ```shell
    helm repo update
    ```

5. **Install the Helm Chart**: This command assumes that there's already an existing Helm chart for Google Tag Manager. As far as I'm aware, Google Tag Manager does not have an official Helm chart. You would actually need to create your own or find one that suits your needs.
    ```shell
    helm install google-tag-manager my-repo/google-tag-manager --namespace default --create-namespace
    ```

Note: Google Tag Manager itself is typically a snippet of JavaScript that you include in your web pages; it isn't normally deployed to Kubernetes. Instead, you might manage containers for your web applications using Kubernetes, and these applications could include Google Tag Manager in their web pages.

If you have not yet created an EKS cluster and installed Helm, the detailed steps above should get you started, and you can refer to these steps for how to deploy Helm charts once everything is set up.
