Deploy the keeweb helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the KeeWeb helm chart on Kubernetes using Pulumi, you will need to use the `Chart` resource from the Kubernetes provider. The `Chart` resource is a high-level abstraction that enables you to deploy Helm charts into a Kubernetes cluster. With Pulumi, you can manage your entire infrastructure with code, including the deployment of applications using Helm on Kubernetes.

Below I will walk you through a Pulumi TypeScript program to deploy the KeeWeb helm chart.

1. **Prerequisites**:
   - A Kubernetes cluster where you have admin permissions.
   - Helm and Pulumi installed on your local machine.
   - `kubectl` configured to connect to your Kubernetes cluster.
   - The Helm chart repository that contains KeeWeb is added to your local Helm configuration.

2. **Setting up the Pulumi Program**:
   - We start by importing the necessary Pulumi and Kubernetes packages.
   - We then use the `Chart` resource to deploy KeeWeb. We specify the chart name and any required values in the `values` parameter.

3. **Deploying the Helm Chart**:
   - The `Chart` resource takes the name of the chart and optionally other parameters like `values` to customize the deployment.
   - `values` can be omitted, supplied directly inline, or provided via a file.

Here's what the Pulumi program looks like:

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

// Define the settings for the keeweb deployment.
const keewebHelmChart = new k8s.helm.v3.Chart("keeweb-chart", {
    chart: "keeweb",
    version: "1.2.3", // Replace with the actual chart version
    fetchOpts: {
        repo: "https://your-helm-chart-repository.com", // Replace with the actual Helm chart repository URL
    },
    // Specify any custom values for the chart (if necessary).
    values: {
        // key: value,
    },
});

// Export the endpoints to access KeeWeb
export const keewebUrl = keewebHelmChart.getResourceProperty("v1/Service", "keeweb-chart", "status").apply(status => {
    // Determine the IP or hostname to connect to the service based on your cluster setup and service type
    return status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip;
});

```

To run this Pulumi program, save it to a file named `index.ts`, and then run `pulumi up`. Pulumi will then interact with your Kubernetes cluster to deploy KeeWeb using the specified Helm chart. After the deployment is complete, Pulumi will output the URL to access KeeWeb if it's exposed as a LoadBalancer service.

Keep in mind that you may need to adjust the `values` field with the specific configuration options required for the KeeWeb chart or your environment. The `version` should match the chart version you intend to deploy, and the `repo` URL should point to the Helm chart repository where KeeWeb is hosted. If the repository requires authentication, you'll need to include that in the `fetchOpts`.

This program assumes that the Helm chart creates a LoadBalancer service for KeeWeb. If the service type or resource names differ, you will need to adjust the resource type and name accordingly in the `keewebUrl` export. Check the Helm chart's documentation or use `helm show values` to understand the available configuration options.
