Deploy the ibm-eventautomation-flink-operator helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying an IBM Event Streams flink operator using a Helm chart in Kubernetes is an operation that involves defining a Pulumi program to create a Helm release. Helm is a popular package manager for Kubernetes, which allows users to define, install, and maintain Kubernetes applications using so-called Helm charts.

Pulumi provides support for Helm charts through its Kubernetes provider. Specifically, you will use the `helm.sh/v3.Chart` resource from the Pulumi Kubernetes provider to deploy the IBM Event Streams flink operator Helm chart.

Below is a program written in TypeScript that demonstrates how to deploy the `ibm-eventautomation-flink-operator` Helm chart on Kubernetes with Pulumi.

Before running the code, you need to have Pulumi installed and configured to access a Kubernetes cluster. You also need to ensure Helm is installed because Pulumi interacts with Helm to deploy the chart.

Here's the step-by-step Pulumi TypeScript program:

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

// Create a Helm Chart resource that will deploy the ibm-eventautomation-flink-operator chart.
const flinkOperatorChart = new k8s.helm.v3.Chart("flink-operator", {
    // Specify the repository where the Helm chart is located.
    // If the chart is located in a custom repository, you will need to
    // provide the `repo` field with the repository URL.
    chart: "ibm-eventautomation-flink-operator",
    // Depending on the chart, you may need to specify the chart version.
    // version: "x.y.z",
    // Here we provide the configuration values that should be used
    // while deploying the Helm chart. These values can be found in
    // the chart's 'values.yaml' file or in the chart's documentation.
    values: {
        // For example, if you need to specify a namespace for the operator:
        // namespace: "eventstreams-operator",
        // ...additional configuration...
    },
    // If the chart requires namespace-scoped resources, define the namespace here.
    // Otherwise, the default namespace in your kubeconfig will be used.
    namespace: "default",
    // Any additional options you might require.
    fetchOpts: {
        // If authentication is required for the Helm repository:
        // username: "your-username",
        // password: "your-password",
    },
});

// Export the deployed Helm chart resources' URNs.
export const chartUrn = flinkOperatorChart.urn;
```

This Pulumi program defines a single Helm chart resource named `flink-operator` using `ibm-eventautomation-flink-operator` as the chart to deploy. If the Helm chart is hosted on a custom Helm repository, you will need to specify the `repo` field with the repository URL.

The `values` property is used to provide configuration values for the Helm chart, typically found in the `values.yaml` file that comes with the Helm chart. For the `ibm-eventautomation-flink-operator` chart, you will need to consult the chart's documentation or the `values.yaml` to determine what configuration options are required or recommended.

This program assumes that your Pulumi setup is already configured to interact with a Kubernetes cluster. Once you run this program with the `pulumi up` command, it will deploy the IBM Event Streams flink operator Helm chart to the specified Kubernetes cluster. The resources' URNs are exported for reference purposes, which allows you to inspect or manage resources created by the chart in other parts of your Pulumi program if needed.

Remember, you will need to adjust the `chart`, `version`, `values`, `namespace`, and `fetchOpts` fields to match the specifics of the IBM Event Stream flink operator Helm chart and your cluster configuration.
