Deploy the provider-aws helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

In order to deploy a `provider-aws` Helm chart on Azure Managed OpenShift Service using Pulumi, you will have to perform a few steps which encompass setting up the Azure Managed OpenShift cluster, setting up infrastructure for Helm, and deploying the Helm chart.

Firstly, you will need to create an OpenShift Managed Cluster on Azure. To interact with Azure services, you'll use the `azure-native` provider in Pulumi, which provides native Azure Resource Manager (ARM) resources. After setting up the cluster, you will use the Pulumi `kubernetes` provider to handle Helm charts. Let's outline the steps:

1. **Set Up Azure Managed OpenShift**: You will create an OpenShift Managed Cluster using `azure-native.containerservice.OpenShiftManagedCluster`. The properties for this resource allow you to customize the cluster as per your requirements, such as setting network profiles, authentication profiles, etc.

2. **Set Up Kubernetes Provider**: The Kubernetes provider is required for Pulumi to interact with a Kubernetes cluster, including OpenShift, which is Kubernetes underneath.

3. **Deploy `provider-aws` Helm Chart**: With the Kubernetes provider configured, you can deploy Helm charts to the cluster. You'll use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider to do this. It's important to note that the `provider-aws` Helm chart should be available in a helm repository or a local path.

Now, let's write the code that performs these actions. Make sure to replace placeholder values with actual information specific to your environment.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Configure the Azure Managed OpenShift Cluster
const openShiftCluster = new azure_native.containerservice.OpenShiftManagedCluster("myOpenshiftCluster", {
    // Define properties as required for the cluster
    resourceGroupName: "myResourceGroup", // Replace with your Azure resource group name
    location: "eastus", // Choose the appropriate Azure location
    openShiftVersion: "latest", // Specify the version of OpenShift
    // Other properties like network profiles, tags, etc., as needed.
});

// Step 2: Create a Kubernetes Provider that points to the new OpenShift cluster
const k8sProvider = new k8s.Provider("openshiftK8s", {
    kubeconfig: openShiftCluster.kubeConfigRaw,
});

// Step 3: Deploy the `provider-aws` Helm chart using the Kubernetes provider
const awsProviderChart = new k8s.helm.v3.Chart("awsProviderChart", {
    chart: "provider-aws", // The name of the chart. Ensure that this is the correct name
    version: "1.0.0", // Specify the chart version, adjust as needed
    // You'll need to provide `repo` or `path` for the chart location
    values: {
        // Define any specific configurations needed by the provider-aws chart here
    },
}, { provider: k8sProvider });

// Export the kubeconfig of the cluster which can be used to connect to the cluster with `kubectl`
export const kubeConfig = openShiftCluster.kubeConfigRaw;

```
Explanation of the Resources Used:
- `azure-native.containerservice.OpenShiftManagedCluster`: This resource is responsible for the creation and configuration of an Azure Red Hat OpenShift cluster in your specified location and resource group.

- `k8s.Provider`: This resource sets up the Kubernetes provider and specifies which cluster it should manage. Here, you are passing the kubeconfig of the OpenShift cluster to the provider so it can authenticate and manage resources.

- `k8s.helm.v3.Chart`: This resource is used to deploy Helm charts on a Kubernetes cluster. It will deploy the `provider-aws` Helm chart on your Azure Managed OpenShift cluster.

Remember:
- Make sure that you've already been authenticated with Azure and have the necessary permissions to create and manage resources.
- You may need to install the `@pulumi/azure-native` and `@pulumi/kubernetes` packages if they're not already installed.
- Replace placeholder values with those specific to your Azure and OpenShift setup.
