Deploy the helm-amq-streams helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the AMQ Streams helm chart on OpenShift, you will use the `kubernetes.helm.sh/v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows you to deploy a Helm chart into a Kubernetes cluster.

Here is a step-by-step guide to deploying AMQ Streams on OpenShift using Pulumi with TypeScript:

1. **Setting up the Pulumi Project**: Make sure you have Pulumi installed and set up a new Pulumi project for TypeScript.

2. **Provider Configuration**: For OpenShift, we will need to configure the Kubernetes provider to point to the OpenShift cluster. Generally, this would involve supplying the kubeconfig file that points to your OpenShift cluster.

3. **Deploying the Helm Chart**: You will need to use the `Chart` resource to specify the AMQ Streams chart from the helm repository or a local chart.

Below is the TypeScript code that performs these steps:

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

// Example assumes that you have already setup your kubeconfig to point to your OpenShift cluster.

// Create a Kubernetes Namespace
const namespace = new k8s.core.v1.Namespace("amq-streams-namespace", {
    metadata: {
        // Define your namespace metadata if necessary
        name: "amq-streams",
    },
});

// Deploy the AMQ Streams Helm chart into the namespace
const amqStreamsChart = new k8s.helm.v3.Chart("amq-streams-chart", {
    namespace: namespace.metadata.name, // Use the created namespace
    chart: "amq-streams",   // The name of the chart
    version: "1.0.0",       // Specify the chart version if necessary
    fetchOpts: {
        repo: "https://your-helm-chart-repository.com/", // Replace this with the Helm repo URL where AMQ Streams chart is hosted
    },
    // Define the values for the Helm release
    values: {
        // Provide necessary values for the AMQ Streams chart
    },
}, { dependsOn: [namespace] }); // Ensure that the namespace is created before the chart is deployed

// Export the Namespace name
export const amqStreamsNamespaceName = namespace.metadata.name;

// To run your Pulumi TypeScript program, you should execute it using the Pulumi CLI:
// $ pulumi up
```

In this program:

- You are importing the Kubernetes package from Pulumi.
- You then create a namespace where the AMQ Streams will be deployed.
- Following that, you create `amqStreamsChart`, which uses the `kubernetes.helm.v3.Chart` resource for deploying AMQ Streams from a specified Helm chart repository. You need to replace `https://your-helm-chart-repository.com/` with the actual Helm repository URL where the AMQ Streams chart is located.
- You can use the `values` property to configure AMQ Streams according to your requirements.
- The `dependsOn` option is used to ensure that resources are created in the correct order, i.e., the namespace before the Helm chart.
- In the end, we are exporting the namespace name which might be useful for other parts of your infrastructure or when querying your deployment with Pulumi.

Before you execute the above program using the `pulumi up` command, make sure that your Pulumi CLI is installed and you are logged into your Pulumi account. Ensure your `kubeconfig` file is set up correctly to connect to your OpenShift cluster.

Please adapt the chart name, version, and repository to your specific AMQ Streams Helm chart details and provide necessary values required to configure your release. If the chart is located locally, you can use the `path` property instead of `repo` to specify its location.
