Deploy the litmus-core helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `litmus-core` Helm chart on OpenShift with Pulumi, you need to perform several steps:

1. Set up the OpenShift cluster and authenticate to it.
2. Add the Helm repository containing the `litmus-core` chart.
3. Use Pulumi's Kubernetes provider to deploy the Helm chart.

I will provide you with a TypeScript program using Pulumi's Kubernetes provider to deploy `litmus-core`. This program assumes that you have an existing OpenShift cluster and are authenticated with `oc` (the OpenShift CLI). Make sure you have the `@pulumi/kubernetes` package installed in your Node.js project.

To deploy the chart, you use a class from the `@pulumi/kubernetes` package called `helm.v3.Chart`. This class represents a Helm chart in a Pulumi program and can be deployed to a Kubernetes cluster.

Here's a program that deploys the `litmus-core` chart to a namespace (assumed to be named `litmus`) in your OpenShift cluster:

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

// Define the Helm chart.
// You may need to specify the exact version of the chart and the Helm repository URL.
const litmusCoreChart = new k8s.helm.v3.Chart("litmus-core", {
    chart: "litmus",
    version: "2.1.0", // Replace with the version of litmus-core you want to deploy
    namespace: "litmus",
    fetchOpts: {
        repo: "https://litmuschaos.github.io/litmus-helm/", // Replace with the Litmus Helm repository if necessary
    },
}, { provider: clusterProvider }); // Make sure to pass the correct OpenShift cluster provider

// Export the chart name
export const chartName = litmusCoreChart.name;
```

This program does the following:
- Imports the necessary Pulumi and Kubernetes modules.
- Creates a new Helm chart resource for `litmus-core`.
- Sets the `chart`, `version`, `namespace`, and Helm repository options for the chart.
- Exports the chart name for easy referencing (useful if you want to query the chart status later with Pulumi).

Please replace `"2.1.0"` with the version number of `litmus-core` you wish to deploy and the repo URL with the correct Helm repository URL for `litmus-core`. If your OpenShift cluster requires a specific Pulumi provider configuration, you should replace `clusterProvider` with the appropriate configuration for your provider.

Be aware that you might need to adapt the `namespace` and other configurations depending on the requirements of your specific OpenShift cluster setup.

To apply this Pulumi program, you would run `pulumi up` in your terminal from the same directory where your Pulumi program is saved.

Remember that deploying the Helm chart requires that you have sufficient permissions in the target OpenShift cluster and that the Helm repository is accessible from within your cluster.
