Deploy the ibm-minio-objectstore helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the IBM MinIO Object Store using a Helm chart on Azure Managed OpenShift Service, you will create a Pulumi program that performs the following steps:

1. **Setup Azure Managed OpenShift**: 
   - Provision an Azure Managed OpenShift cluster using [`azure-native.containerservice.OpenShiftManagedCluster`](https://www.pulumi.com/registry/packages/azure-native/api-docs/containerservice/openshiftmanagedcluster/), which will give you a Kubernetes-compliant environment managed by Microsoft and Red Hat.
   
2. **Deploy the IBM MinIO Helm Chart**:
   - Utilize the Pulumi Kubernetes provider to deploy the IBM MinIO Object Store Helm chart to the OpenShift cluster.

Here's the TypeScript program:

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

// Step 1: Provision an Azure Managed OpenShift Cluster
// Attributes are selected to reflect a minimal viable cluster setup.
// Modify the parameters according to your requirements.

const resourceGroup = new azureNative.resources.ResourceGroup("resourceGroup", {
    resourceGroupName: "openshiftResourceGroup",
    location: "East US", // Azure region for resources, change it as needed.
});

const openshiftCluster = new azureNative.containerservice.OpenShiftManagedCluster("openshiftCluster", {
    resourceName: "myOpenshiftCluster",
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    openShiftVersion: "v3.11", // specify your desired OpenShift version
    // Define the network profile, router profiles, authProfile, and other configurations as required.
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        count: 3, // For high availability
        vmSize: "Standard_D4s_v3", // Subject to your performance needs
    },
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_D4s_v3", // Match the size as per your workloads
    }],
}, { dependsOn: [resourceGroup] });

// Step 2: Deploy the IBM MinIO Helm Chart on the cluster
// To deploy the Helm chart, we need to take the following steps:

// 2.1 Initialize the Kubernetes provider using the OpenShift cluster's kubeconfig
const provider = new k8s.Provider("openshiftK8s", {
    kubeconfig: openshiftCluster.config.apply(config => JSON.stringify(config)),
});

// 2.2 Deploy the IBM MinIO Helm chart
const minioChart = new k8s.helm.v3.Chart("minioChart", {
    // The repository could be third-party or host the charts in a repository reachable by your cluster
    repo: "ibm-minio-repo", // You need to specify the correct helm repo here
    chart: "minio",
    // Override default values with your required configurations
    values: {
        accessKey: "YOUR-MINIO-ACCESS-KEY",
        secretKey: "YOUR-MINIO-SECRET-KEY",
        // Include other necessary chart values here
    },
    namespace: "default", // Define the namespace where you wish to deploy
}, { provider }); // Ensure it uses the initialized provider

// Export the kubeconfig to access the OpenShift cluster
export const kubeConfig = openshiftCluster.config;
```

**Explanation:**

1. We first created an Azure resource group that will contain all of our Azure resources. The location for the resources is set to "East US" but can be changed as needed.

2. Then, we provisioned an Azure Managed OpenShift cluster with a specified OpenShift version, network configuration, a number of master nodes (for control plane, set to 3 for high availability), and agent nodes (for worker nodes).

3. We initialized the Kubernetes provider with the kubeconfig from the provisioned OpenShift cluster.

4. We deployed the IBM MinIO Object Store Helm chart specifying the helm repository, chart name, and values such as access and secret keys. It's important to use the correct helm repository where the IBM MinIO chart is hosted. Additional values may be passed as needed to fit the deployment to your workload.

5. Finally, we exported the kubeconfig which can be used to access the OpenShift cluster using `kubectl` or other Kubernetes-compatible tools.

This program will produce a running instance of MinIO on an Azure OpenShift cluster when executed with Pulumi.

To run this program you will need to install Pulumi and configure your Azure credentials. If you haven't installed Pulumi yet or set up your Pulumi Azure provider, please follow [Pulumi's Azure Getting Started guide](https://www.pulumi.com/docs/get-started/azure/).

Once you have Pulumi set up, you will have to install the necessary Pulumi packages in your project:

```bash
pulumi plugin install resource azure-native 2.11.0
pulumi plugin install resource kubernetes 4.4.0
npm install @pulumi/azure-native @pulumi/kubernetes
```

You can then compile this program with `tsc` if it's saved as `index.ts`, and run it using the `pulumi up` command. After deployment, use the exported `kubeConfig` to manage your OpenShift cluster with kubectl or any other Kubernetes tooling.
