Deploy the typo3scan helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `typo3scan` Helm chart on Kubernetes using Pulumi, you will need to use the Pulumi Kubernetes provider. One of the resources provided by this provider that can be used to deploy a Helm chart is the `Chart` resource from the `kubernetes.helm.sh/v3` module.

Using the `Chart` resource, you specify the Helm chart you want to install (in this case, `typo3scan`), along with several configuration options such as the chart version, any custom values you want to provide, and the namespace to install the chart into.

Here's how you could write a Pulumi program in TypeScript to deploy the `typo3scan` Helm chart to your Kubernetes cluster:

1. First, ensure you have Pulumi installed and configured to access your Kubernetes cluster.
2. Then, make sure you have the correct Helm chart repository that contains the `typo3scan` chart added on your local machine, as Pulumi will use the Helm CLI to fetch charts. This step is necessary if the chart is not available in the default Helm repository.

Now, let's start with the Pulumi program:

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

// Define a new Kubernetes Helm chart for typo3scan
const typo3scanChart = new k8s.helm.v3.Chart("typo3scan", {
    // Specify chart details
    chart: "typo3scan",
    // If typo3scan is not in the default Helm chart repo or you are using a specific version,
    // specify the `repo` and `version` properties here, for example:
    // repo: "https://my-charts.example.com/",
    // version: "1.2.3",
    
    // Provide custom values for the chart
    // This is a placeholder - replace these with actual values for the typo3scan Helm chart
    values: {
        // e.g., serviceType: "LoadBalancer",
    },
    
    // Specify the namespace to deploy the chart into. If this namespace does not exist,
    // Pulumi will create it as part of the deployment
    namespace: "typo3scan-ns",
});

// Export the chart name
export const chartName = typo3scanChart.metadata.name;
```

Here's a breakdown of the program:

- We import the `@pulumi/kubernetes` package, which contains the necessary modules for working with Kubernetes in Pulumi.
- We create a new instance of `Chart` resource with the identifier `"typo3scan"`.
- We specify the chart details such as the name of the chart. If the chart requires a specific repository or version, you would include that information as well.
- We provide specific configuration values that the `typo3scan` Helm chart expects. These values must match what the chart expects and will vary depending on the chart details.
- We specify the namespace where the chart should be deployed. Pulumi will create the namespace if it doesn't already exist.
- Finally, we export the name of the Helm chart so that it can be easily retrieved if needed, such as when querying the deployment status via `kubectl` or the Pulumi CLI.

To use this program:

1. Save the code to a file named `index.ts`.
2. Run `pulumi up` to create the resources defined in the program. Pulumi will show a preview of the resources that will be created and ask for confirmation before proceeding.
3. If everything looks correct, confirm the deployment, and Pulumi will deploy the `typo3scan` chart to your Kubernetes cluster.

Keep in mind that the Helm chart values and repository will depend on the specifics of the `typo3scan` chart you are trying to deploy, which you would need to replace with actual values in the `values` section of the code.
