Deploy the teredix helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the teredix Helm chart on Azure Managed OpenShift Service using Pulumi, you'll need to follow these steps:

1. Set up an Azure Managed OpenShift cluster.
2. Install the Helm chart to the OpenShift cluster.

The Pulumi program will first define an Azure Managed OpenShift cluster using the `azure-native.redhatopenshift.OpenShiftCluster` resource. Once your cluster is available, you'll then use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider to install the teredix Helm chart into the cluster.

Before running this program, you need to have an `OpenShiftClientConfig` file configured to connect to your Azure OpenShift cluster. You also need to ensure that you have the appropriate Azure permissions and the Pulumi CLI installed and configured for Azure.

Here is the TypeScript program that defines both the cluster and the Helm chart deployment:

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

// Define an Azure Managed OpenShift cluster.
const resourceGroupName = 'my-openshift-resources';
const clusterName = 'my-openshift-cluster';

const resourceGroup = new azure.resources.ResourceGroup(resourceGroupName);

const openshiftCluster = new azure.redhatopenshift.OpenShiftCluster(clusterName, {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    // Fill in other required fields like 'clusterProfile', 'masterProfile', 'networkProfile' based on your specific requires
});

// Once the cluster is provisioned, we can deploy the Helm chart to it.
// This Pulumi component requires that kubectl is configured to point to the Kubernetes cluster.
const teredixChart = new k8s.helm.v3.Chart("teredix-chart", {
    chart: "teredix",
    version: "1.0.0", // specify the version you want to deploy
    namespace: "default", // specify the Kubernetes namespace for the helm chart
    // You can include any values you would typically set in a values.yaml file or with '--set'.
    // For example: 
    values: {
        service: {
            type: "LoadBalancer"
        }
    },
    // Specify the repo where your chart is located
    // For example: 
    // fetchOpts: { 
    //     repo: "https://example.com/helm-charts",
    // },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: openshiftCluster.kubeconfig }) });

// Export the URL to access the deployed application
export const teredixUrl = teredixChart.getResourceProperty("v1/Service", "default", "teredix-service", "status").apply(status => status.loadBalancer.ingress[0].ip);
```

This program does the following:
- Creates an Azure Managed OpenShift cluster within a new resource group. Note that additional cluster configuration details must be added, like profiles for the cluster, master, and network. 
- Deploys the `teredix` Helm chart to the newly created OpenShift cluster. You need to specify the chart version and any applicable configurations analogous to Helm's `values.yaml` file.

You would also need to specify the repository where your Helm chart is hosted if it is not in the default Helm repository.

Once the program is successfully executed, it will output the IP address that can be used to access your `teredix` service if it is exposed as a LoadBalancer.

Before running this Pulumi program, please ensure that you have set up your Pulumi and Azure credentials correctly. You can use the Pulumi CLI to create a new Pulumi project and paste this TypeScript code into the `index.ts` file. After that, run `pulumi up` to provision the resources as defined.
