Deploy the redroid-emulator helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the redroid-emulator helm chart on Azure Managed OpenShift Service using Pulumi, we will perform the following steps:

1. Set up an Azure Managed OpenShift Cluster.
2. Configure the Kubernetes provider to target the Azure Managed OpenShift Cluster.
3. Use the Helm Chart resource to deploy redroid-emulator on the cluster.

First, make sure you have the Azure and Kubernetes provider SDK installed for Pulumi. You can do this by running `npm install @pulumi/azure-native @pulumi/kubernetes`.

Here's a Pulumi program in TypeScript that performs these steps:

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

// Step 1: Create an Azure Managed OpenShift Cluster.
const openShiftCluster = new azureNative.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    // Provide the required attributes for your cluster
    resourceGroupName: "myResourceGroup", // Replace with your resource group name
    openShiftVersion: "4.3", // Specify the OpenShift version
    location: "East US",    // Specify the Azure region
    // Define agent pool, network settings and other properties as per your requirements
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_DS3_v2", // Specify VM size
    }],
    // ... other necessary configuration
});

// Step 2: Configure the Kubernetes provider to target the Azure Managed OpenShift Cluster.
const creds = pulumi.all([openShiftCluster.name, openShiftCluster.resourceGroupName]).apply(([name, rg]) => {
    return azureNative.containerservice.listOpenShiftManagedClusterAdminCredentials({
        resourceName: name,
        resourceGroupName: rg,
    });
});

const kubeConfig = creds.kubeconfigs[0].value.apply((v) => Buffer.from(v, 'base64').toString());

const k8sProvider = new kubernetes.Provider("myK8sProvider", {
    kubeconfig: kubeConfig,
});

// Step 3: Deploy the redroid-emulator Helm chart to the OpenShift Cluster using the Kubernetes provider.
const redroidEmulatorChart = new kubernetes.helm.v3.Chart("redroid-emulator", {
    // The repository where the redroid-emulator chart is located, typically you might need to add the chart repo
    // Typically using `helm repo add ...` command, here you will need to find the chart location or its url
    chart: "redroid-emulator",
    version: "0.1.0", // Specify chart version, if required
    // Specify any values.yaml attributes if needed, for example:
    // values: {
    //     service: {
    //         type: "LoadBalancer", // or other values depending on your requirements
    //     },
    //     // ... other necessary configuration
    // },
}, { provider: k8sProvider });

// Export the OpenShift cluster's kubeconfig
export const kubeConfigOut = kubeConfig;
```

### Detailed Explanation:

- We start by importing the necessary Pulumi SDK packages to manage resources in Azure and Kubernetes.
- We define a new OpenShiftManagedCluster resource, specifying its attributes like the agent pool profile, location, version, and any other required settings. Make sure to replace placeholder values with the actual values required for your setup.
- We then retrieve the admin credentials for the newly created OpenShift cluster using the `listOpenShiftManagedClusterAdminCredentials` function. These credentials are required to configure the Kubernetes provider to manage resources in the cluster.
- We create a new instance of the Kubernetes provider, `myK8sProvider`, passing the `kubeConfig` obtained from the OpenShift cluster. This configures Pulumi to connect to and manage resources in the OpenShift cluster.
- With the Kubernetes provider configured, we deploy the `redroid-emulator` Helm chart using the `Chart` resource from the `@pulumi/kubernetes` package. We specify the name of the Helm chart and its version. You will need to provide the Helm chart's repository if it's not in the default Helm repository listings.
- Finally, we export the kubeconfig using Pulumi's `export` function. This value can be used to access the Kubernetes dashboard or for kubectl commands outside of Pulumi.

You should replace placeholder values with actual values you want to use for your OpenShift cluster and emulator deployment. The `values` field in the `redroid-emulator` chart instantiation should be filled out according to the specific configuration options required by the redroid-emulator chart.

Once the program is ready, you deploy it by running `pulumi up`. This will provision the Azure Managed OpenShift cluster, configure Kubernetes to connect to it, and deploy the redroid-emulator Helm chart.
