Deploy the quay helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the Quay Helm chart on Azure Managed Openshift Service using Pulumi, you will need to follow these high-level steps:

1. Create an Azure Resource Group to organize all the resources.
2. Deploy an Azure Red Hat OpenShift (ARO) cluster.
3. Configure the Kubernetes provider to interact with the ARO cluster.
4. Use the Helm Chart resource to deploy the Quay Helm chart to the ARO cluster.

Here's a detailed walkthrough and the corresponding Pulumi TypeScript program:

### Step 1: Create an Azure Resource Group
An Azure Resource Group is a container that holds related resources for an Azure solution. In Pulumi, you can create a resource group using the `ResourceGroup` class from the `azure-native.resources` module.

### Step 2: Deploy Azure Red Hat OpenShift Cluster
You can create an OpenShift cluster in Azure using the `OpenShiftCluster` class from the `azure-native.redhatopenshift` module.

### Step 3: Configure Kubernetes Provider
Once the OpenShift cluster is deployed, you need to set up the Kubernetes provider with the kubeconfig from the deployed OpenShift cluster. This will allow Pulumi to interact with the cluster and deploy workloads.

### Step 4: Deploy Quay Helm Chart
Using the `Chart` resource from the `@pulumi/kubernetes/helm/v3` package, you can deploy the Quay Helm chart. You need to specify the repository and chart name, and you may also provide custom values to configure the Quay deployment.

Here is the Pulumi TypeScript program:

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

// Step 1: Create an Azure Resource Group
const resourceGroup = new azureNative.resources.ResourceGroup("myResourceGroup");

// Step 2: Deploy Azure Red Hat OpenShift Cluster
const openShiftCluster = new azureNative.redhatopenshift.OpenShiftCluster("myOpenShiftCluster", {
    // ... provide required properties like location, resourceName, etc.
    // Please refer to the Pulumi documentation for the complete list of properties
    // Documentation: https://www.pulumi.com/registry/packages/azure-native/api-docs/redhatopenshift/openshiftcluster/
    resourceGroupName: resourceGroup.name,
    // ... other required properties
});

// Retrieve the kubeconfig for the OpenShift cluster after it is created
const kubeconfig = pulumi.all([openShiftCluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => {
    // Logic to retrieve kubeconfig for the ARO cluster
    // Typically involves Azure API calls to get credentials
});

// Step 3: Configure Kubernetes Provider
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeconfig,
});

// Step 4: Deploy Quay Helm Chart
const quayChart = new k8s.helm.v3.Chart("quay", {
    chart: "quay",
    version: "3.5.4", // specify the version of Quay you wish to deploy
    fetchOpts: {
        repo: "https://charts.quay.io/", // specify the Helm chart repository URL
    },
    // Optionally, you can provide custom values using the 'values' property
    values: {
        // ... custom Quay configuration values go here
    },
}, { provider: k8sProvider });

// Export the URL of the deployed Quay instance (if applicable)
export const quayUrl = pulumi.interpolate`http://${quayChart.getResourceProperty("v1/Service", "quay-quay", "status").apply(status => status.loadBalancer.ingress[0].ip)}`;
```

Before you can run this program, make sure you have set up the Pulumi CLI and authenticated with Azure. When the program is executed, it will create the resources in the specified order, and, if successful, will output the URL to access the Quay instance. In the values section for the Quay Helm chart deployment, you would fill in the specific configuration options you want for your Quay deployment.

Keep in mind that deploying an OpenShift cluster can take a considerable amount of time, and you should also make sure you have the necessary permissions and quotas in your Azure account. Also, ensure you've included all required properties for the OpenShift cluster, which can be found in the [Pulumi Azure Native documentation](https://www.pulumi.com/registry/packages/azure-native/api-docs/redhatopenshift/openshiftcluster/).

After the deployment, you would interact with Quay through the provided URL, which would be an IP address assigned by Azure's LoadBalancer for your service.
