Deploy the vault-secrets helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the vault-secrets Helm chart on a Kubernetes cluster using Pulumi, you would typically follow these steps:

1. Set up a Pulumi project and select the appropriate stack (Kubernetes cluster context where you want to deploy the chart).
2. Choose the right Pulumi Kubernetes provider and import it into your TypeScript program.
3. Define a `Chart` resource from the Helm package, specifying the chart name, version, values, and other configurations as necessary.

The `kubernetes.helm.v3.Chart` is a Pulumi resource that allows you to deploy a Helm chart into a Kubernetes cluster. The Helm chart could be from any Helm chart repository, or from a local directory. When you define a `Chart` resource, Pulumi will invoke Helm in the background to deploy that chart to your Kubernetes cluster, creating all of the Kubernetes resources defined by the chart.

Here's a TypeScript program which deploys the vault-secrets Helm chart to a Kubernetes cluster:

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

// Create an instance of the Kubernetes provider.
const provider = new k8s.Provider("provider", {
    // Specify the kubeconfig or context if it is not the default one.
});

// Deploy the vault-secrets Helm chart from a Helm repository.
const vaultSecretsChart = new k8s.helm.v3.Chart("vault-secrets", {
    chart: "vault-secrets", // Name of the chart. Replace with the correct chart name.
    version: "1.0.0", // Replace with the desired chart version.
    // Add chart values here, e.g. replicaCount: 1
    values: { /* your values here */ },
    // Specify the namespace if needed, otherwise default is used.
    namespace: "default", 
}, { provider });

// Optionally, export the chart name and other outputs as needed.
export const chartName = vaultSecretsChart.metadata.apply(m => m.name);
export const namespace = vaultSecretsChart.metadata.apply(m => m.namespace);
```

Before running this program, ensure you have access to a Kubernetes cluster and your Pulumi setup is configured with access to the cluster, typically through a `kubeconfig` file.

Replace the `chart`, `version`, and `values` fields with the actual details of the `vault-secrets` Helm chart you want to deploy. The `values` field is an object that holds the configuration values for the chart which would override the default values set in the Helm chart's `values.yaml`.

Once your setup is complete, and you have this TypeScript file ready, you can deploy it using Pulumi CLI commands:

```sh
pulumi up
```

This command will start the deployment process. Pulumi will show you a preview of what resources will be created, modified, or deleted. Confirm the action to proceed with the deployment.

If you need more information on how to set up a Pulumi project or install Pulumi, please refer to the [official Pulumi documentation](https://www.pulumi.com/docs/get-started/).

Remember, working with Helm charts means you'll need both Helm and Pulumi installed on your machine, and you'll need to have Helm configured with access to chart repositories, if the chart you're deploying isn't local.
