Deploy the elasticsearch-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Elasticsearch Operator Helm chart on OpenShift using Pulumi, you'll want to use the Helm chart resource provided by Pulumi's Kubernetes provider. The `kubernetes.helm.v3.Chart` resource allows you to deploy Helm charts to a Kubernetes cluster. OpenShift is a Kubernetes distribution, so you can interact with it using Pulumi's Kubernetes provider in much the same way as you would with any other Kubernetes cluster.

Below, I'll walk you through the process of writing a Pulumi program in TypeScript to deploy the Elasticsearch Operator on OpenShift. Please ensure you have the `pulumi`, `kubectl`, and `helm` CLI tools installed and configured correctly for your OpenShift cluster. Also, before running this Pulumi program, you'll need to be logged into your OpenShift cluster where you want to deploy the Elasticsearch Operator.

Here's a detailed breakdown of the Pulumi program:

1. Import the necessary modules from Pulumi.
2. Create a Helm Chart resource specifying the Elasticsearch Operator chart’s details like the chart name, version, and the repository where the chart is hosted.

Please note that you may need to adjust the `repo` and `chart` properties in the program to match the actual repository URL and chart name of the Elasticsearch Operator you intend to use. Also, you might want to specify other properties under the `values` field to configure the Elasticsearch Operator according to your needs.

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

const elasticsearchOperatorReleaseName = "elasticsearch-operator";
const elasticsearchOperatorNamespace = "default"; // Specify the namespace where the operator will be installed
const elasticsearchOperatorChartVersion = "1.0.0"; // Replace with the correct chart version

// Instantiate an Elasticsearch Operator Helm chart from the stable repo.
const elasticsearchOperatorChart = new k8s.helm.v3.Chart(elasticsearchOperatorReleaseName, {
    chart: "elasticsearch-operator", // Replace with the correct chart name
    version: elasticsearchOperatorChartVersion,
    namespace: elasticsearchOperatorNamespace,
    fetchOpts: {
        repo: "https://charts.example.com/repository", // Replace with the correct Helm chart repository URL
    },
    // If needed, you can provide additional configuration values for your Helm chart here.
    values: {
        // For example, to set a custom value:
        // someCustomValue: "value"
    },
});

// Export the URL of the Elasticsearch cluster, which can be used to interact with it once it’s up and running.
export const elasticsearchURL = elasticsearchOperatorChart.getResourceProperty(
    "v1/Service", // Assuming the chart creates a Service object for accessing Elasticsearch; change if different
    `${elasticsearchOperatorReleaseName}-elasticsearch-cluster`, // The name of the service, change it if your Helm chart uses a different name
    "status"
).apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);
```

The above code will deploy the Elasticsearch Operator to your currently connected OpenShift cluster. Replace the placeholder values with the appropriate values for your specific chart. After running this, you will have the Elasticsearch Operator deployed and can begin to create Elasticsearch clusters using the operator's CRDs.

Remember, after writing this code to a TypeScript (.ts) file, you must run `pulumi up` to instruct Pulumi to perform the deployment to your OpenShift cluster. Make sure to review the proposed changes before confirming, as Pulumi will provide you with a preview of what resources will be created, updated, or deleted.
