Deploy the sealed-secrets-operator helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying a Helm chart on Kubernetes involves a few steps:

1. **Setting up the Kubernetes Provider:** We need to configure the Pulumi Kubernetes provider in order to communicate with the cluster where the Helm chart will be deployed.
2. **Deploying the Helm Chart:** Once the provider is set up, we utilize the `Chart` resource from the Pulumi Kubernetes library to deploy the Helm chart. The `Chart` resource is a high-level interface that allows us to deploy Helm charts into a Kubernetes cluster.

Here's a TypeScript program that demonstrates how to use Pulumi to deploy the `sealed-secrets-operator` Helm chart to a Kubernetes cluster:

1. First, we'll import the necessary libraries from Pulumi:
    - `@pulumi/kubernetes`: Provides the resources to interact with Kubernetes clusters.
2. Then, we will set up the Kubernetes provider and deploy the chart. In this example, we're assuming default kubeconfig credentials. If you are targeting a specific cluster or context, you would configure the provider with the appropriate context or kubeconfig file.

Below is the detailed TypeScript program. Ensure that Pulumi CLI is installed and configured with access to your Kubernetes cluster. This program is ready to deploy as is, provided you have Kubernetes access configured in your environment:

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

// You can specify the version of the 'sealed-secrets-operator' chart and the release name.
const version = "1.0.0"; // Replace with the desired chart version
const releaseName = "sealed-secrets-operator";

// Create an instance of the 'sealed-secrets-operator' Helm chart. The Helm chart is fetched from
// the specified repository, and we're deploying it to the "default" namespace.
const sealedSecretsOperatorChart = new k8s.helm.v3.Chart(releaseName, {
    chart: "sealed-secrets-operator",
    version: version,
    fetchOpts: {
        repo: "https://bitnami-labs.github.io/sealed-secrets", // This should be the correct repo for the sealed-secrets operator
    },
    // You can specify additional configuration options here, such as custom values
    // If you need to override default values in the Helm chart, you can do so by using the 'values' field
    // values: { /* Custom values can be placed here */ }
}, { provider: k8sProvider }); // Ensure you have a properly configured Kubernetes provider

// The program's output can include the name of the chart and its status.
// This information can be useful when you need to reference or manage the deployed resources.
export const chartName = sealedSecretsOperatorChart.metadata.apply(meta => meta.name);
export const chartStatus = sealedSecretsOperatorChart.status.apply(status => status);

// Lastly, you will need to run `pulumi up` to deploy this chart to your Kubernetes cluster.
```

This program defines a single Helm chart resource and will deploy the `sealed-secrets-operator` in the default namespace. Before applying the above code, make sure that you have selected the right project and stack, or you can create a new project and stack if you are just starting with Pulumi. To apply the code, save it in a `index.ts` file and execute `pulumi up` in the command line, and Pulumi will handle the deployment of the chart to your cluster.

If you need to customize the deployment, such as changing the namespace or adding configuration values, modify the `Chart` resource's arguments accordingly. To expose the necessary outputs or statuses of the deployment, use Pulumi's `export`, which allows you to retrieve information about the deployment once it's completed.
