Deploy the directus helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To achieve your goal of deploying the Directus Helm chart on Azure Managed OpenShift Service using Pulumi, we need to accomplish the following steps:

1. Set up an Azure Managed OpenShift cluster.
2. Install the Helm chart for Directus onto the cluster.

For step 1, we can use the `azure-native.containerservice.OpenShiftManagedCluster` resource, which provisions an OpenShift cluster in Azure. For step 2, we will leverage the `kubernetes.helm.v3.Chart` resource from Pulumi's Kubernetes provider to deploy the Directus Helm chart to our OpenShift cluster.

Below is the TypeScript program that performs these two steps. Make sure you have the Pulumi CLI installed and configured to access your Azure account. You also need to have the `@pulumi/azure-native` and `@pulumi/kubernetes` packages installed in your project.

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

// Step 1: Create an Azure Resource Group
const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup");

// Step 2: Create an Azure Managed OpenShift Cluster
const openshiftCluster = new azure.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    openShiftVersion: "v4.x", // specify your desired version
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        count: 3,
        vmSize: "Standard_D4s_v3",
    },
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_D4s_v3",
    }],
    // An example setting, more configurations may be required based on your specific needs
});

// Step 3: Use Pulumi's built-in Kubernetes provider to interact with the OpenShift cluster
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: openshiftCluster.config.kubeconfig,
});

// Step 4: Deploy the Helm chart for Directus
const directusChart = new k8s.helm.v3.Chart("directus", {
    chart: "directus",
    version: "X.Y.Z", // replace with the version you wish to deploy
    fetchOpts: {
        repo: "https://charts.directus.io/", // Use the correct Helm repo for Directus
    },
}, { provider: k8sProvider });

// Export the Kubernetes config and Directus service endpoint
export const kubeconfig = openshiftCluster.config.kubeconfig;
export const directus_endpoint = directusChart.getResourceProperty("v1/Service", "directus", "status").apply(status => status.loadBalancer.ingress[0].ip);
```

### Explanation

- We start by creating a new Azure resource group which will contain all of our resources.
- We provision an Azure OpenShift cluster with the desired version and VM sizes. The network and agent pool profiles are configured as needed for our cluster.
- We instantiate a Pulumi Kubernetes provider, which uses the kubeconfig from the OpenShift cluster we just created. This provider allows us to interact with the cluster to deploy Kubernetes resources.
- We deploy the Directus Helm chart using Pulumi's `Chart` resource from the `@pulumi/kubernetes` package. Replace `X.Y.Z` with the version of the Directus chart you want to deploy and make sure the `repo` property points to the official Directus Helm chart repository.
- Finally, we export the kubeconfig for accessing our OpenShift cluster and the service endpoint for Directus.

After running the Pulumi program, you'll be able to access the Directus instance using the exported service endpoint. Note that additional configurations for Directus or networking might be required based on your specific deployment requirements.
