Deploy the sdnc-prom helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `sdnc-prom` Helm chart on an OpenShift cluster using Pulumi, you'll need to interact with Kubernetes resources. For this task, the `kubernetes.helm.v3.Chart` resource is quite suitable. It allows you to deploy a chart from a Helm repository, assuming the chart you are referring to, `sdnc-prom`, is available in a repository.

Below is a Pulumi program written in TypeScript that demonstrates how to use the `kubernetes.helm.v3.Chart` resource to deploy a Helm chart to an OpenShift cluster. Before running this program, ensure you have configured Pulumi to use the OpenShift or Kubernetes cluster where you want to deploy the Helm chart.

The program assumes that you're already authenticated with your OpenShift cluster and have the necessary permissions to deploy applications.

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

// Define the settings of the Helm chart you want to deploy.
// You'll need to replace `chartVersion` and `repoURL` with the appropriate values for the sdnc-prom chart.
const chartName = "sdnc-prom";
const chartVersion = "1.0.0"; // The version of the Helm chart
const repoURL = "https://charts.example.com/"; // The Helm chart repository URL

const sdncPromChart = new k8s.helm.v3.Chart(chartName, {
    chart: chartName,
    version: chartVersion,
    fetchOpts: { repo: repoURL },
    // If your Helm chart requires specific values, define them here.
    // values: { key: value },
    namespace: "default", // Specify the OpenShift namespace where to deploy the chart.
}, { provider: openshiftProvider }); // The `openshiftProvider` should be configured to point to your OpenShift cluster.

export const chartStatus = sdncPromChart.status;

```

This Pulumi program does the following:

1. Imports the Kubernetes package from Pulumi, which is used to deploy Kubernetes resources, including Helm charts.
2. Defines the settings for the Helm chart deployment, including the chart's name, version, and repository URL. These will need to be replaced with the correct values for the `sdnc-prom` chart.
3. Creates a new Helm chart resource using the `k8s.helm.v3.Chart` class. This will attempt to pull the specified Helm chart from the provided repository and deploy it to the OpenShift cluster.
4. Assumes that you have already set up a `Provider` for OpenShift, represented as `openshiftProvider`. This provider must be correctly configured to communicate with your OpenShift cluster.
5. Optionally, if the Helm chart requires custom values, they can be supplied in the `values` field.

After running the above program with the `pulumi up` command, Pulumi will perform the deployment to your OpenShift cluster. You can verify the deployment by checking the resources in the specified namespace or by using the OpenShift CLI tool.

Remember that you will need to replace the placeholders in the program with actual values that pertain to the `sdnc-prom` chart and your OpenShift cluster configuration.
