Deploy the puppet helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an OpenShift cluster using Pulumi, you will need to have the OpenShift cluster already set up. The following program will use Pulumi's Kubernetes provider to deploy a Puppet Helm chart to your OpenShift cluster.

Before you begin, you will need to install the Pulumi CLI and set up your OpenShift `kubeconfig` file for Pulumi to use. Once you've done that, you can use the following Pulumi code in TypeScript:

1. First, we will import the necessary Pulumi package for Kubernetes.
2. Next, we define a Helm chart resource, specifying the chart name (in this case, assumed to be "puppet") and the values that you want to configure. If the Puppet Helm chart is hosted on a custom Helm repo, you'll need to include the `repo` property in the chart definition.
3. We also specify the namespace where you want to deploy the chart on your OpenShift cluster. If the namespace does not already exist, you should create it or ensure that your chart includes the namespace resource.

Here is the Pulumi program that accomplishes the deployment:

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

// Deploy a Puppet Helm chart on an OpenShift cluster using Pulumi.

// Create an instance of the Helm chart to be deployed.
// NOTE: You need to replace the `REPO_URL` and `CHART_VERSION` placeholders
// with the actual URL of the Puppet Helm chart repository and the version of the chart you want to install.
const puppetChart = new kubernetes.helm.v3.Chart('puppet', {
    chart: 'puppet',
    version: 'CHART_VERSION', // Specify the chart version
    fetchOpts: {
        repo: 'REPO_URL', // Specify the repository URL where the chart is hosted
    },
    namespace: 'default' // Specify the namespace. Can be changed to a different one if required.
}, { provider: /* your openshift provider reference here if needed */ });

// Export the status URL of the Helm release.
export const puppetStatusUrl = puppetChart.status.apply(status => status.url);
```

This Pulumi program will deploy the Puppet chart with its default configurations. If you have a specific configuration you wish to apply, you can pass a `values` object with the desired configuration to the `Chart` resource.

Replace `REPO_URL` with the URL to your Helm chart's repository, and `CHART_VERSION` with the specific chart version you want to deploy.

After saving the above code in a file named `index.ts`, you can run it using Pulumi CLI commands:

```sh
pulumi up
```

This command will initialize the Pulumi program, prompt you for confirmation, and proceed with the deployment of the Puppet Helm chart to your OpenShift cluster. Make sure you're logged in to the correct Pulumi account and have selected the right stack that points to the target OpenShift cluster.

Remember, the code provided assumes you already have an OpenShift cluster running and configured with Pulumi. If you need to set up a new OpenShift cluster or configure it with Pulumi, additional steps and resources would be necessary.
