Deploy the kube-arangodb-crd helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `kube-arangodb-crd` Helm chart on a Kubernetes cluster using Pulumi, we will use the `Chart` resource from the Pulumi Kubernetes provider. The `Chart` resource is used to deploy a Helm chart and can specify the values required for deployment by assigning them to the `values` property.

Here is a step-by-step breakdown of the code:

1. We import the necessary Pulumi and Kubernetes packages.
2. We create a new Kubernetes provider instance, which is used to deploy resources to a particular Kubernetes cluster. We assume that your Kubernetes configuration (Kubeconfig) is set up correctly to access your cluster.
3. We create an instance of the `Chart` resource, specifying the name of the Helm chart and additional configuration parameters if required. The chart `kube-arangodb-crd` will be fetched from the Helm repository, where it is hosted.
4. We specify the namespace where the chart will be deployed. If it's not provided, it will use the default namespace set up in your Kubeconfig. If the namespace doesn't exist, it will be created.

Now let's write the TypeScript program to deploy your chart:

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

// Initialize a new Kubernetes provider using the context of your current kubeconfig
const provider = new kubernetes.Provider("k8s-provider", {});

// Parameters for the deployment, such as chart version and Helm repository URL may be required
const chartRepoUrl = "https://arangodb.github.io/kube-arangodb";
const chartVersion = "1.2.3"; // Replace with the actual chart version you wish to deploy

// Deploy kube-arangodb-crd Helm chart
const arangoCrdChart = new kubernetes.helm.v3.Chart("kube-arangodb-crd-chart", {
    // Specify the chart name and version
    chart: "kube-arangodb-crd",
    version: chartVersion,
    // Specify the repository URL where the chart is hosted
    fetchOpts: {
        repo: chartRepoUrl,
    },
    // You can specify custom values for the Helm chart here
    values: {
        // Include any custom configuration here
    },
    // Define the namespace where the chart will be deployed
    namespace: "default", // Change if you want to deploy into a different namespace
}, { provider });

// Export any relevant information, such as the chart name
export const chartName = arangoCrdChart.metadata.name;
```

This Pulumi program will deploy the `kube-arangodb-crd` Helm chart into your Kubernetes cluster. Remember to replace the `chartVersion` with the specific version of the chart you want to deploy and update the repository URL if it differs.

Once this code is run using the Pulumi CLI, Pulumi will reach out to the specified Helm repository, download the chart, and deploy the resources defined by the chart into your Kubernetes cluster.

Ensure that you have the necessary permissions to deploy resources into the Kubernetes cluster and that the Helm chart version you are trying to deploy is compatible with your cluster’s version.
