Deploy the terraform-enterprise helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Terraform Enterprise helm chart on a Kubernetes cluster using Pulumi, we'll follow these steps:

1. Set up a Kubernetes cluster: First, you need an active Kubernetes cluster. For the purpose of this example, we're assuming you have a cluster up and running and have configured `kubectl` to interact with it.

2. Install the Pulumi Kubernetes provider: This provider allows Pulumi to work with Kubernetes resources, such as Helm charts.

3. Deploy the Helm chart: We'll define a deployment using the `kubernetes.helm.v3.Chart` resource. This resource specifies the Helm chart to deploy, which repository it's from, and any configuration values needed.

4. Initialize the Pulumi project and stack: Initialize your Pulumi project and select the appropriate stack (environment). This is where you would write the code and deploy from. But for simplicity, we're assuming you have Pulumi CLI installed and a stack initialized.

Here's the TypeScript program that performs these steps:

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

// Create an instance of the Helm chart for Terraform Enterprise. 
// You need to specify the correct repository URL and any relevant configurations 
// in the `values` field.
const terraformEnterpriseChart = new k8s.helm.v3.Chart("terraform-enterprise", {
    chart: "terraform-enterprise",
    version: "x.y.z", // Replace with the correct chart version
    fetchOpts: {
        repo: "https://helm.releases.hashicorp.com", // The repository URL where the chart can be found
    },
    // Include values here if you need to customize the chart's default config.
    // For example:
    // values: {
    //   setSensitive: {
    //     name: "some-value",
    //     value: "some-sensitive-data",
    //     secret: true,
    //   },
    // },
});

// This export is useful if you need the chart name programmatically
// for post-deployment scripts or tests.
export const chartName = terraformEnterpriseChart.metadata.name;
```

In this code:

- We're importing the Kubernetes package from Pulumi's module library.
  
- We're creating a new Helm chart resource using `new k8s.helm.v3.Chart`, which will deploy the Terraform Enterprise Helm chart to your cluster.

- The `chart` argument specifies the name of the chart to deploy, which in this case is "terraform-enterprise".

- The `version` is a placeholder and should be replaced with the specific version of the Terraform Enterprise Helm chart that you want to deploy.

- The `fetchOpts` property includes the repository where the helm chart can be found. Terraform Enterprise helm chart is available in HashiCorp's helm repository.

- If you need to provide a specific configuration for the helm chart, you can do so using the `values` object. This is akin to passing a `values.yaml` file when using Helm directly.

- Finally, we're exporting the `chartName` which is useful for other processes that might depend on the release name after deployment.

Before running this program with Pulumi, make sure to replace `"x.y.z"` with the actual version of the Terraform Enterprise Chart. You may also need to include other configuration options in the `values` property to satisfy any prerequisites for Terraform Enterprise.

To actually deploy this Pulumi program, navigate to your project's directory in the terminal and run `pulumi up`. This command will perform a preview of the deployment and, if everything looks correct, you can confirm the deployment to proceed.
