Deploy the ibm-datapower-dev helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the `ibm-datapower-dev` Helm chart on an Azure Managed OpenShift Service using Pulumi, we will follow a few steps:

1. Set up the Azure Managed OpenShift cluster using `azure-native.containerservice.OpenShiftManagedCluster`.
2. Deploy the `ibm-datapower-dev` Helm chart to the cluster using `kubernetes.helm.v3.Chart`.

First, we will create an instance of the Managed OpenShift cluster. We will need to define the necessary parameters like the location, resource group name, cluster properties, etc. Take note that for a real deployment, specific values like `resourceName`, `resourceGroupName`, and `location` have to be set according to your Azure subscription and desired configuration. We're using placeholder values as this is a learning example.

Once the cluster is set up, we use the `kubernetes.helm.v3.Chart` resource to deploy the Helm chart. In this step, we need to configure the Helm chart with its specific release name, namespace, and any configuration values required by the `ibm-datapower-dev` chart.

Now, let's proceed with the Pulumi TypeScript program to accomplish these steps:

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

// Create a new managed OpenShift cluster.
const cluster = new azureNative.containerservice.OpenShiftManagedCluster("myCluster", {
    resourceGroupName: "myResourceGroup",
    resourceName: "myOpenShiftCluster",
    location: "eastus", // Change to the region you want your cluster in
    openShiftVersion: "4.3", // Specify the OpenShift version
    // Specify other properties as required, for example:
    // networkProfile, masterPoolProfile, agentPoolProfiles...
});

// Once the OpenShift cluster is created, we can configure Kubernetes provider to point to this cluster.
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: cluster.config.kubeconfig,
});

// Deploy the ibm-datapower-dev helm chart on the OpenShift cluster.
const helmChart = new k8s.helm.v3.Chart("datapowerChart", {
    chart: "ibm-datapower-dev",
    version: "1.0.0", // Choose the version of the Helm chart you want to deploy
    namespace: "default", // You can specify a different namespace
    // Define values to customize the release
    values: {
        // Provide any specific configuration for ibm-datapower-dev helm chart
    },
}, { provider: k8sProvider });

// Export the OpenShift cluster's kubeconfig.
export const kubeConfig = cluster.config.kubeconfig;
```

In the above program:

- We use the [`azure-native.containerservice.OpenShiftManagedCluster`](https://www.pulumi.com/registry/packages/azure-native/api-docs/containerservice/openshiftmanagedcluster/) to provision an Azure Managed OpenShift cluster.
- We set up a [`kubernetes.helm.v3.Chart`](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/) resource for deploying the Helm chart. Note that we did not specify the `repo` property, as it defaults to the stable repository. You would need to set this to the correct Helm repository containing the `ibm-datapower-dev` chart.

Remember to replace placeholder values with actual data for a deployment. You'd need to ensure you have the necessary permissions and configurations set up in your Azure account and your Pulumi setup.

After running this Pulumi program, the OpenShift cluster will be set up in your Azure account, and the `ibm-datapower-dev` Helm chart will be deployed in it.
