Deploy the tinyproxy-exporter helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the `tinyproxy-exporter` Helm chart on Azure Managed OpenShift Service using Pulumi, you will need to follow these steps:

1. Set up an Azure Managed OpenShift cluster.
2. Deploy the `tinyproxy-exporter` Helm chart to the OpenShift cluster.

We will use the `azure-native.containerservice.OpenShiftManagedCluster` resource to create an Azure OpenShift cluster and the `kubernetes.helm.sh/v3.Chart` resource from the Kubernetes provider to deploy the Helm chart.

Let's break this down step by step:

### Step 1: Create an Azure Managed OpenShift Cluster

First, you need to create an OpenShift cluster on Azure. To do this, use the `azure-native.containerservice.OpenShiftManagedCluster` resource, which represents an Azure Red Hat OpenShift cluster. You will need to specify a resource group, the location, the OpenShift version, and other necessary parameters like the agent pool profiles for your worker nodes and master nodes.

### Step 2: Deploy the Helm Chart

Once you have an OpenShift cluster, you can deploy the `tinyproxy-exporter` Helm chart to it. Use the `kubernetes.helm.sh/v3.Chart` resource for defining and installing Helm charts on a Kubernetes cluster. You will need to specify the chart name and optionally version and values to customize the deployment.

Below is the complete Pulumi TypeScript program that will perform both steps:

```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
const resourceGroup = new azureNative.resources.ResourceGroup("myResourceGroup", {
    location: "East US", // Choose the appropriate Azure region for your OpenShift cluster
});

// Define the Managed OpenShift cluster
const managedCluster = new azureNative.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    // Replace the below details with your own specifications
    resourceName: "myOpenShiftCluster",
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    openShiftVersion: "4.3", // Ensure this version is available in your selected region
    tags: {
        environment: "production",
    },
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        count: 3,
        vmSize: "Standard_D4s_v3",
    },
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_D4s_v3",
        role: "compute",
    }],
});

const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: managedCluster.config.adminKubeconfigRaw.apply(c => c!), // Unwrap the kubeconfig from the cluster
});

// Define the Helm chart for `tinyproxy-exporter`
const helmChart = new k8s.helm.sh.v3.Chart("tinyproxyExporterChart", {
    chart: "tinyproxy-exporter",
    // Add the repository details if the chart is not in the default helm repo
    fetchOpts: {
        repo: "http://myhelmrepo.example.com/", // Replace with the actual Helm repo URL
    },
    // Set the values for the Helm chart
    values: {
        // Specify the chart values here, as per the chart's requirements
    },
}, { provider: k8sProvider });

// Export the cluster name and kubeconfig
export const clusterName = managedCluster.name;
export const kubeConfig = managedCluster.config.adminKubeconfigRaw;
```

This program does the following:

- Instantiates a new Azure Resource Group.
- Creates an Azure Managed OpenShift cluster within that resource group, with specified configuration for networking, size, and number of nodes.
- Sets up a Kubernetes provider that uses the kubeconfig obtained from the newly created OpenShift cluster.
- Defines a Helm chart resource targeting the `tinyproxy-exporter` Helm chart, using the Kubernetes provider to deploy the chart to the cluster.

Please note that this is a basic configuration and may require additional details such as the chart's version or custom configuration values according to the `tinyproxy-exporter` chart's documentation and the specific needs of your application.

After creating this program file, you can deploy the infrastructure using the following Pulumi CLI commands:

```bash
pulumi up
```

Remember to replace placeholders (like `http://myhelmrepo.example.com/`) with actual values relevant to your deployment. Also, ensure you have the correct access rights set up in Azure and Pulumi is configured correctly for your Azure account.
