Deploy the hive-server helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `hive-server` Helm chart on OpenShift using Pulumi, you will need to use the Pulumi Kubernetes provider. The Kubernetes provider uses the Helm Chart resource to deploy Helm charts. Below, I will provide a program that uses Pulumi with TypeScript to deploy a `hive-server` Helm chart onto an OpenShift cluster.

Before you begin, ensure that you have Pulumi installed, the Pulumi CLI configured, and access to an OpenShift cluster. You should also have `kubectl` configured to communicate with your OpenShift cluster. The Pulumi program will assume that these prerequisites are met.

Here is a step-by-step program to deploy the `hive-server` Helm chart:

1. **Setting up the Pulumi program**: We initiate a Pulumi program by creating a new directory and initializing the Pulumi project with `pulumi new`.
2. **Importing Dependencies**: We begin by importing necessary modules. We will need the `@pulumi/kubernetes` package to interact with Kubernetes resources, such as the Helm chart.
3. **Creating a Helm Chart Resource**: We will use the `Chart` class from the `@pulumi/kubernetes/helm/v3` module to deploy the `hive-server` Helm chart. This class will manage the installation and updates of the Helm chart in your OpenShift cluster.
4. **Configuring the Helm Chart**: To configure the Helm chart, we supply the chart name, and optionally, the repository where the chart can be found.
5. **Deploying the Helm Chart**: Pulumi will now deploy the Helm chart to your connected OpenShift cluster, creating all necessary Kubernetes resources.

The following TypeScript program implements the above steps to deploy the `hive-server` Helm chart:

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

// Define the Helm chart for hive-server, you might need to supply the appropriate repository
// and chart version depending on where the hive-server chart is hosted and the version you wish to use.
const hiveServerChart = new kubernetes.helm.v3.Chart("hive-server", {
    chart: "hive-server",
    // If your chart is in a custom Helm repo, uncomment the following lines and provide the repo URL
    // repo: "https://your-helm-chart-repo.com/", 
    // version: "x.y.z", // Specify the chart version
    namespace: "hive-server-namespace", // Specify the namespace, if needed
    // values: { /* Chart values to override */ }, // Uncomment and specify to set chart values
});

// Export the base URL to access the hive-server, usually it will be service endpoint or ingress
export const hiveServerUrl = hiveServerChart.getResourceProperty(
    "v1/Service", "hive-server", "status"
).apply(status => status.loadBalancer.ingress[0].hostname);

```

### Explanation

- **Importing Dependencies**: We include the Pulumi Kubernetes SDK to work with Kubernetes resources.
- **Creating a Helm Chart Resource**: We create a Helm chart resource providing the name `'hive-server'`. You would need to uncomment and provide additional configuration if your Helm chart is in a custom repository.
- **Configuring the Helm Chart**: If necessary, you can specify the namespace where the chart should be deployed, the version of the chart, and any custom values that need to be overridden. Remember to replace `https://your-helm-chart-repo.com/` with the actual URL of your Helm chart's repository and specify the exact version you need.
- **Output**: After running `pulumi up`, Pulumi will interact with the Kubernetes API to install the Helm chart into your OpenShift cluster. The export statement makes the `hive-server` URL accessible and can be retrieved by running `pulumi stack output hiveServerUrl`.

After you have this code, save it in a file, for example, `index.ts`. You can then run `pulumi up` to deploy the `hive-server` Helm chart to your OpenShift cluster.

Note that while this Pulumi program will work to deploy a Helm chart, specific details about the `hive-server` Helm chart like its repository or configurations are needed to complete the deployment successfully, which are to be provided in place of the placeholders in the commented areas.
