Deploy the mlflow-helm-chart helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `mlflow-helm-chart` on OpenShift with Pulumi, you will utilize the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This resource enables you to deploy Helm charts to a Kubernetes cluster, which in this case is an OpenShift cluster.

Before you begin, ensure that you have the following prerequisites fulfilled:
1. Pulumi CLI installed.
2. `kubectl` configured to interact with your OpenShift cluster.
3. Helm and the Helm chart repository containing the `mlflow-helm-chart`.

Here is the Pulumi TypeScript program that would deploy the `mlflow-helm-chart` on OpenShift:

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

const namespace = new k8s.core.v1.Namespace("mlflow-namespace", {
    metadata: { name: "mlflow" }
});

const mlflowRelease = new k8s.helm.v3.Chart("mlflow-helm-chart", {
    repo: "repo-name", // Replace with the name of the repository containing the chart
    chart: "mlflow",   // Replace with the name of the chart if different
    version: "version", // Specify the chart version if necessary
    namespace: namespace.metadata.name, // Deploy the chart in the created namespace
    values: { // Provide any configuration options necessary for your setup
        // Configuration values for mlflow-helm-chart
        // Example:
        // service: {
        //   type: "ClusterIP"
        // },
        // Refer to the Chart's values.yaml file for a full list of configuration options.
    },
}, {
    provider: k8sProvider, // This assumes you have a Pulumi Kubernetes provider configured for OpenShift
});

export const mlflowUrl = mlflowRelease.getResourceProperty("v1/Service", "mlflow-helm-chart-mlflow", "status").apply(status => status.loadBalancer.ingress[0].hostname);
```

Explanation:

- You first import the necessary Pulumi Kubernetes package.
- Create a Kubernetes namespace for the MLflow deployment.
- Deploy the MLflow Helm chart using `k8s.helm.v3.Chart`. `repo`, `chart`, and `version` should be replaced with the correct information from the Helm chart you wish to deploy. If you don't specify a version, Helm will default to the latest available version.
- The `values` field is an object that should match the configuration options available for the `mlflow-helm-chart`. These are equivalent to the values you would override in a `values.yaml` file when using Helm directly. You will need to refer to the chart's documentation or its `values.yaml` for the options you can set.
- Lastly, an export of the MLflow service's URL is provided, assuming the chart exposes MLflow through a Kubernetes service of type `LoadBalancer`. If the service is exposed differently, for instance through an `Ingress` or `ClusterIP`, you will need to alter this accordingly.

Remember to replace placeholders such as `repo-name` and `version` with correct information based on the MLflow Helm chart you're using.

Configure your OpenShift Kubernetes provider as needed for Pulumi to communicate with it. If you haven't configured this yet, you can set it up following the instructions [here](https://www.pulumi.com/registry/packages/kubernetes/).

To run this Pulumi program:

1. Save the code to a file named `index.ts`.
2. Run `pulumi up` from the command line in the same directory as your `index.ts`.

This command will initiate the deployment process managed by Pulumi, which will communicate with your OpenShift cluster to realize the desired state as defined in the program.
