Deploy the zookeeper-helm-chart helm chart on Opensshift

To deploy the zookeeper-helm-chart on OpenShift using Pulumi, you'd typically use the kubernetes.helm.v3.Chart resource. This resource allows you to deploy Helm charts into a Kubernetes cluster.

Firstly, ensure you have the following prerequisites in place:

• An OpenShift cluster where you have administrative access.
• The helm CLI tool installed on your local machine.
• The Pulumi CLI installed and configured for TypeScript.
• The kubectl CLI configured to communicate with your Openshift cluster.

Now, let's walk through a Pulumi program that accomplishes your goal.

1. Setting up the Pulumi TypeScript project: Ensure you have a new Pulumi TypeScript project set up. If you don't have one, you can create it by using pulumi new typescript.

2. Referencing the Helm Chart: You will reference the Zookeeper Helm chart using the kubernetes.helm.v3.Chart from the @pulumi/kubernetes package, specifying the necessary chart details such as the chart name, version, and any custom values you want to override.

3. Applying the helm chart to OpenShift: The Pulumi program will then interact with the OpenShift cluster to deploy this Helm chart when applying the stack updates.

Here's a step-by-step TypeScript program that rolls out the zookeeper-helm-chart Helm chart on OpenShift:

import * as k8s from '@pulumi/kubernetes';

// Create an instance of the Helm Chart for Zookeeper.
// Zookeeper chart details such as repository and version could be specified;
// otherwise, they will be fetched from the default Helm repo.
const zookeeperChart = new k8s.helm.v3.Chart('zookeeper-helm-chart', {
    chart: 'zookeeper',
    // Specify the version of the chart you wish to deploy.
    // Not providing a version or values will result in the latest version and default settings.
    version: '<chart-version>', // Replace with the specific Chart version
    fetchOpts: {
        repo: 'https://<helm-chart-repository-url>', // Replace with the Helm repository URL
    },
    // For OpenShift, depending on the setup, you might need to include additional configuration.
    // For example, many OpenShift clusters require setting a security context:
    values: {
        // Additional configuration values can be set based on the specific requirements of the chart being used.
        // Refer to the Helm chart's documentation for possible customizable values.
        securityContext: {
            fsGroup: 1001,
            runAsUser: 1001,
        },
    },
    namespace: 'default', // Specify the namespace where the chart should be installed.
    // Add other necessary configurations specific to your OpenShift setup if required.
});

// Export the chart name and version.
export const chartName = zookeeperChart.chart;
export const chartVersion = zookeeperChart.version;

This program defines a Pulumi resource that will install the Zookeeper Helm chart into your connected OpenShift cluster when deployed.

It's important to replace <chart-version> with the specific version of the chart you want and https://<helm-chart-repository-url> with the URL of the Helm repository that hosts the Zookeeper chart.

Also, modify the values section to match the configurations needed for your instance of Zookeeper on OpenShift. Ensure these values align with the OpenShift’s security context and any other requirements that the chart has.

Remember that to run this Pulumi program, you must have Pulumi installed and configured on your machine. After writing this code into your index.ts file in your Pulumi project directory, deploy it using the Pulumi CLI:

pulumi up

This command will prompt you to confirm the deployment after showing you a preview of the resources Pulumi is going to create or modify. Once confirmed, Pulumi will apply the changes to your OpenShift cluster, and the Zookeeper Helm chart will be deployed.
