Deploy the hydra-maester helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the hydra-maester helm chart on Azure Managed OpenShift Service, you will first need to create an OpenShift Managed Cluster within Azure. Once the cluster is up and running, you can then deploy the hydra-maester helm chart to the cluster. Below is a detailed guide on how to achieve this with Pulumi in TypeScript.

### Step 1: Set up the OpenShift Managed Cluster
First, you need to define an Azure Managed OpenShift cluster using the `azure-native.containerservice.OpenShiftManagedCluster` resource. You need to specify parameters such as `resourceGroupName`, `location`, and `openShiftVersion`, as well as details for the networking, such as `vnetCidr`.

### Step 2: Deploy the Hydra-Maester Helm Chart
After setting up the OpenShift cluster, you will deploy the hydra-maester chart. To do this, use the Pulumi Kubernetes provider to deploy a Helm chart using the `kubernetes.helm.v3.Chart` resource. You'll provide the name of the chart, `hydra-maester`, and specify its repository and version. Additionally, you can fine-tune your deployment by providing configuration values if required.

Here is a complete program written in TypeScript that performs both steps:

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

// This should be replaced with actual config or parameters
const config = {
    resourceGroupName: "myResourceGroup",
    location: "East US",
    openShiftVersion: "4.3.0",
};

// Create an Azure Resource Group
const resourceGroup = new azure_native.resources.ResourceGroup("resourceGroup", {
    resourceGroupName: config.resourceGroupName,
    location: config.location,
});

// Create an Azure OpenShift Managed Cluster
const managedCluster = new azure_native.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    resourceGroupName: config.resourceGroupName,
    resourceName: "myOpenShiftCluster",
    location: config.location,
    openShiftVersion: config.openShiftVersion,
    // Network Profile is required - specify a valid CIDR
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    // Specify other required and optional properties as needed
}, { dependsOn: [resourceGroup] });

// Deploy the Hydra-Maester Helm chart
const hydraChart = new k8s.helm.v3.Chart("hydra-maester", {
    chart: "hydra-maester",
    version: "0.1.0", // replace with the desired chart version
    fetchOpts: {
        repo: "https://k8s.ory.sh/helm/charts", // replace with the helm chart's repository
    },
    namespace: "default", // replace with the namespace where you want to deploy
    // Values can be customized based on the helm chart's requirements
    values: {
        // Add required configuration values here
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: managedCluster.kubeConfigRaw }) });

// Export the cluster's kubeconfig and public hostname
export const kubeConfig = managedCluster.kubeConfigRaw;
export const clusterHostname = managedCluster.hostname;
```

In the above program:

- The `resourceGroup` resource defines an Azure Resource Group where all resources are stored.
- The `managedCluster` resource creates an OpenShift Managed Cluster with the provided configuration.
- The `hydraChart` resource deploys the hydra-maester helm chart to the cluster using Pulumi's Kubernetes provider.

**Note:** Ensure that you replace the values such as `resourceGroupName`, `location`, and any other placeholders with your actual parameters. Similarly, the helm chart version and the repository should point to the correct source where the hydra-maester chart is hosted.

Run `pulumi up` to start the deployment process. Pulumi will perform the necessary actions to create the resources in Azure and deploy the helm chart to your OpenShift cluster.
