Deploy the skopeo-sync helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the Skopeo-Sync Helm chart on Azure Managed OpenShift Service, you'll need to follow these steps:

1. **Set up Azure Managed OpenShift Service**: First, you'll need to create an instance of Azure Red Hat OpenShift (ARO), which is a managed OpenShift service provided by Microsoft and Red Hat.

2. **Install the Helm CLI**: Helm is a package manager for Kubernetes, which you use to deploy applications like Skopeo-Sync. Ensure you have Helm installed on your local machine.

3. **Create the Pulumi Code**: You'll be writing TypeScript code in Pulumi to perform these actions. The Pulumi Kubernetes provider allows you to write your infrastructure code in familiar programming languages and manage Kubernetes resources such as namespaces, deployments, and services.

4. **Deploy the Helm chart**: Once your OpenShift cluster is set up, use Pulumi to deploy the Skopeo-Sync Helm chart to your Azure Managed OpenShift Service.

Let's construct a Pulumi program to deploy the Skopeo-Sync Helm chart:

First, we need to create the OpenShift Managed Cluster resource. Pulumi's Azure Native provider includes the `OpenShiftManagedCluster` class for this purpose. Since this operation involves creating a cluster, it may take several minutes to complete. Once the cluster is ready, you can deploy the Helm chart using the `Chart` resource from the Pulumi Kubernetes provider.

Below is a TypeScript program that sets up an Azure Managed OpenShift cluster and deploys the Skopeo-Sync Helm chart.

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

// Create an Azure Resource Group to hold the OpenShift cluster
const resourceGroup = new azureNative.resources.ResourceGroup("myResourceGroup");

// Deploy an Azure Managed OpenShift cluster
const openShiftCluster = new azureNative.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    // Replace these with appropriate values or generate them
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    openShiftVersion: "4.3", // Specify the desired OpenShift version
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        count: 3,
        vmSize: "Standard_D4s_v3", // Choose the appropriate VM size
    },
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_D4s_v3", // Choose the appropriate VM size
        role: "compute",
    }],
    // If required, add additional configurations such as authentication profiles, tags, etc.
});

// Once the OpenShift cluster is deployed, use the cluster's kubeconfig to interact with it
const kubeconfig = openShiftCluster.config.apply(c => c);

// Create a Kubernetes provider instance using the kubeconfig from the OpenShift cluster
const k8sProvider = new k8s.Provider("myK8sProvider", {
    kubeconfig: kubeconfig,
});

// Deploy the Skopeo-Sync Helm chart on the Azure Managed OpenShift Service
const skopeoSyncChart = new k8s.helm.v3.Chart("skopeo-sync", {
    chart: "skopeo-sync",
    // Specify the version of the chart, repository, and any custom values
    // version: "1.2.3",
    // repo: "myHelmRepo",
    // values: {
    //     key1: "value1",
    //     // Add any necessary values here
    // },
}, { provider: k8sProvider });

// Export the cluster name and kubeconfig
export const clusterName = openShiftCluster.name;
export const clusterKubeconfig = kubeconfig;
```

This program performs the following operations:
- It defines an Azure Resource Group to organize related resources.
- Creates an Azure Managed OpenShift cluster within this group using the `OpenShiftManagedCluster` class.
- Specifies the version of the OpenShift platform, network, and agent pool profiles with a minimum required configuration.
- Retrieves the kubeconfig which allows you to interact with your OpenShift cluster.
- Then, it sets up a Pulumi Kubernetes provider using the obtained kubeconfig.
- It deploys the Skopeo-Sync Helm chart on your OpenShift cluster using the `Chart` resource.
  
Make sure to replace placeholders (like the OpenShift version, VM sizes, and the Helm chart details, including the repository and version) with actual values relevant to your deployment.

Once you have this program in place, you can execute it using the Pulumi CLI commands as follows:
- Run `pulumi up` to preview and deploy your changes.
- Once the deployment is complete, use `pulumi stack output clusterKubeconfig` to obtain the kubeconfig for your newly created OpenShift cluster.

Please note that you will need to install the necessary Pulumi CLI tools and set up authentication with Azure and your Kubernetes cluster for this program to execute correctly.
