Deploy the flink-app helm chart on Opensshift
TypeScriptTo deploy the
flink-app
Helm chart on an OpenShift cluster using Pulumi, you will leverage the Pulumi Kubernetes provider. This provider allows us to work with Kubernetes resources, including managing Helm charts.Before you can deploy a Helm chart, you'll need to have access to an OpenShift cluster and have configured
kubectl
on your local machine to communicate with the cluster. I'll walk you through creating a Pulumi program that will deploy a Helm chart, but please ensure you have the necessary cluster access before running this Pulumi code.Here are the steps we'll follow in the Pulumi program:
- Import necessary libraries: We'll import the Pulumi Kubernetes library to work with Kubernetes resources.
- Create a Kubernetes Provider: This is how Pulumi communicates with your OpenShift cluster. It's set up to use your current
kubectl
configuration. - Define the Helm Release: We'll define a Helm Release resource to deploy the
flink-app
chart.
Now, here is the Pulumi program in TypeScript that performs this deployment:
import * as k8s from "@pulumi/kubernetes"; // Step 1: Provide the namespace where you want to deploy your application. const namespace = "default"; // You might want to change "default" to a specific namespace // Step 2: Define the Helm chart release. Adjust the "repo" and "chart" properties to point to the correct chart. const flinkAppChart = new k8s.helm.v3.Chart("flink-app", { namespace, chart: "flink-app", // Replace this with the actual chart name, if it's different // If the Helm chart is from a custom repository, specify `repo` and optionally `version` // repo: "https://your-helm-chart-repo.com", // version: "1.2.3", // values: { /* Your customization values here */ } }, { provider: k8sProvider }); // Attach the cluster provider, if it's not the default // Step 3: (Optional) Export any useful information, for example the app service URL. // If `flink-app` service creates an external endpoint, you can retrieve and export its URL like this: // export const flinkAppServiceUrl = flinkAppChart.getResourceProperty("v1/Service", "flink-app", "status").apply(s => s.loadBalancer.ingress[0].ip);
In this program:
- We use
@pulumi/kubernetes
to interact with Kubernetes resources, which includes deploying Helm charts. - We define the
flink-app
Helm chart and (optionally) provide custom values if required. You must replace the placeholderchart
value with the actual name of the chart you're deploying. - We comment out the repository and version information, as you would need to uncomment and provide this information if you are using a chart from a custom Helm repository.
- The
k8sProvider
argument for theChart
resource is commented out as it should be used if you've explicitly created a provider that's different from the one picking up the current context fromkubectl
.
Keep in mind that you might need to adjust the
values
property to accommodate any specific configurations for the Helm chart you're deploying.Please make sure you've set up Pulumi and
kubectl
, and you are authorized to deploy to the OpenShift cluster. You can run this program with Pulumi CLI after saving it to a file with a.ts
extension, and you of course need Node.js and npm/yarn to manage dependencies.
