Deploy the tempo-mixin helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the `tempo-mixin` Helm chart on Azure Managed OpenShift Service using Pulumi, you'll first need to instantiate an OpenShift cluster on Azure, and then use the Helm chart resource to deploy `tempo-mixin` into that cluster.

Below is a Pulumi TypeScript program that outlines these steps. This program consists of two main resources:
1. `azure-native.containerservice.OpenShiftManagedCluster`: This is the Azure Managed OpenShift Service cluster that you'll be deploying your Helm chart into.
2. `kubernetes.helm.v3.Chart`: The Helm chart resource which will deploy `tempo-mixin`.

Prior to running this program, ensure you have the following prerequisites met:
- Pulumi CLI installed.
- An Azure account with the necessary permissions to create OpenShift clusters and deploy Helm charts.
- Configured the Azure provider for Pulumi using `az login` or by setting appropriate environment variables.
- Installed the `@pulumi/azure-native` and `@pulumi/kubernetes` npm packages.

Here is the Pulumi program for deploying `tempo-mixin` on Azure Managed OpenShift:

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

// Step 1: Create an Azure Managed OpenShift cluster
const openshiftCluster = new azure.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    // Replace the placeholders with actual values
    resourceGroupName: pulumi.interpolate`myResourceGroup`,
    openShiftVersion: "latest", // Specify the desired OpenShift version
    location: "East US", // Specify the preferred Azure location

networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        count: 1, // Specify the number of master nodes
        vmSize: "Standard_DS3_v2", // Specify the VM size
    },
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3, // Specify the number of agent nodes
        vmSize: "Standard_DS3_v2", // Specify the VM size
        role: "compute", // Specify the role (compute/infra)
    }],
    // ... additional required configurations
});

// Use the KubeConfig from the newly created OpenShift cluster to configure the Kubernetes provider
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: openshiftCluster.config.apply(c => c.kubeconfig),
});

// Step 2: Deploy the tempo-mixin Helm chart into the OpenShift cluster
const tempoMixinChart = new k8s.helm.v3.Chart("tempoMixin", {
    chart: "tempo-mixin",
    // Replace with the correct Helm repository containing the 'tempo-mixin' chart
    fetchOpts: {
        repo: "https://helm.repository.url",
    },
    // Specify values for the chart as needed
    values: {
        // Your chart values go here
    },
}, { provider: k8sProvider });

// Export the OpenShift cluster's KubeConfig and Helm chart deployment status
export const kubeConfig = openshiftCluster.config.apply(c => c.kubeconfig);
export const deployedChart = tempoMixinChart.status.apply(s => s);
```

This program performs the following actions:
- Defines an Azure Managed OpenShift cluster (`OpenShiftManagedCluster`) in the specified resource group, location, and with the desired node counts and VM sizes.
- Creates a Pulumi Kubernetes provider that uses the KubeConfig from the OpenShift cluster for authentication.
- Defines a Helm chart resource that uses this provider to deploy the `tempo-mixin` Helm chart from the specified Helm repository into the cluster.

Make sure to replace placeholders with your own values, such as the resource group name, Azure location, and the repository URL for the Helm chart.

After setting up the program, deploy it using the Pulumi CLI by navigating to the directory containing your Pulumi program and running:

```bash
pulumi up
```

This will start the deployment process, and Pulumi will provide you with a preview of the resources that will be created. Confirm the deployment to proceed and wait for Pulumi to report completion.
