Deploy the so helm chart on Opensshift

Question

Pulumi · Accepted Answer

Helm charts are a popular way to package and deploy applications on Kubernetes clusters. If you have a Helm chart named "so" that you would like to deploy on an OpenShift cluster using Pulumi, you can do so with the Pulumi Kubernetes provider.

The Pulumi Kubernetes provider uses the Kubernetes API to create, update, and manage Kubernetes resources, including Helm charts. The resource we will use to deploy a Helm chart is `kubernetes.helm.v3.Chart`, which represents a Helm Chart resource in a Kubernetes cluster.

Below, I'll write you a Pulumi program in TypeScript that deploys the "so" Helm chart to an OpenShift cluster. I assume you've already got `kubectl` configured to communicate with your OpenShift cluster and that Pulumi is set up to use your Kubernetes configuration.

To deploy a Helm chart, you will need the following:
1. The name of the Helm chart (`"so"` in this case).
2. The repository where the Helm chart is located (if it's not a local chart).
3. Any specific values you want to override in the chart's `values.yaml` file.

Here's a program that demonstrates how to deploy a Helm chart to OpenShift:

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

// Create an instance of the Helm chart. 
// Assuming "so" is the name of your Helm chart, and it's available in a public chart repository.
const soChart = new kubernetes.helm.v3.Chart("so-chart", {
    // Replace with the namespace where you want to install your chart.
    namespace: "your-namespace", 
    // Replace with the repo where your 'so' chart is located.
    chart: "so", 
    // Version of the Helm chart to install.
    version: "x.y.z", 
    // If your Helm chart is hosted on a chart repository, specify the repo URL.
    fetchOpts: {
        repo: "https://charts.yourrepository.com/",
    },
    // Specify any custom values you want for your Helm chart.
    values: {
        // ... your custom values here
    },
}, { provider: openshiftProvider });

// Export the base URL for the deployed application (if applicable)
export const baseUrl = soChart.getResourceProperty("v1/Service", "so-chart-name", "status").apply(status => status.loadBalancer.ingress[0].hostname);
```

Make sure to replace `"your-namespace"`, `x.y.z`, and the `values` with the actual namespace, version, and any custom values relevant to your Helm chart. The `repo` field within the `fetchOpts` should point to the repository URL where your Helm chart is hosted.

Also, the line for exporting `baseUrl` is an example of how you could export a URL that's created as part of the deployment process, which might not apply depending on the nature of the service deployed by your Helm chart (for example, a database most likely wouldn't have a public endpoint).

Remember to install the `@pulumi/kubernetes` package before running your Pulumi program:

```bash
npm install @pulumi/kubernetes
```

Run `pulumi up` to execute your deployment. Pulumi will reach out to the cluster, create the necessary resources, and deploy the "so" Helm chart as specified.

Keep in mind that you need to connect this to the appropriate OpenShift provider instance (`openshiftProvider`) in Pulumi. If you have the OpenShift provider configured, you should pass your provider instance to the `Chart` resource. This example assumes you have a provider configured that can manage resources in your OpenShift cluster.

Pulumi has a wide array of [documentation](https://www.pulumi.com/docs/) and [examples](https://www.pulumi.com/docs/intro/cloud-providers/kubernetes/#examples) that can be helpful as you explore further capabilities and options.
