Deploy the delta-sharing-server helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying the `delta-sharing-server` Helm chart on OpenShift can be accomplished using Pulumi's Kubernetes provider. The Kubernetes provider allows us to interact with a Kubernetes cluster and deploy applications using Helm charts. Helm is a package manager for Kubernetes that facilitates the packaging, distribution, and deployment of applications.

In the Pulumi program below, we'll create an OpenShift cluster and then deploy the `delta-sharing-server` Helm chart using the `Chart` resource from Pulumi's Kubernetes provider. Please ensure that you have the Helm chart details like the repository URL and the chart name before proceeding. If the Helm chart requires specific configurations, they can be provided using the `values` property.

Here is the TypeScript program that deploys the `delta-sharing-server` Helm chart to an OpenShift cluster:

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

// Create an instance of the Kubernetes provider configured for OpenShift.
const openshiftProvider = new k8s.Provider("openshift", {
    // Assuming you have OpenShift credentials configured in your kubeconfig file
    // Otherwise, you can provide the appropriate context to the provider.
    // kubeconfig: "<kubeconfig-content>",
});

// Define the values we want to override in the Helm chart.
// Replace these with the actual values you require for the delta-sharing-server configuration.
const deltaSharingServerValues = {
    // For example purposes, using placeholder values.
    // Replace these with actual configurations corresponding to your environment.
    image: "delta-sharing-server-image",
    service: {
        type: "LoadBalancer",
        port: 80,
    },
    // Add any other configuration values that the chart requires or you want to override.
};

// Deploy the delta-sharing-server Helm chart.
const deltaSharingServerChart = new k8s.helm.v3.Chart("delta-sharing-server", {
    // Provide the repository URL where your Helm chart is located.
    // Make sure that the repository is accessible from your OpenShift cluster.
    repo: "repository-url",
    chart: "delta-sharing-server",
    version: "chart-version", // Specify the version of the chart.
    values: deltaSharingServerValues,
    // Choose the namespace where you want to deploy the Helm chart.
    // If this namespace doesn't exist, you'll need to create it or use an existing one.
    namespace: "default",
}, { provider: openshiftProvider });

// Export relevant resources (URLs, primarily)
export const deltaSharingServerEndpoint = deltaSharingServerChart.getResource("v1/Service", "delta-sharing-server-service").status.loadBalancer.ingress[0].hostname;
```

In this program:

- We import the Kubernetes package from Pulumi (`@pulumi/kubernetes`) to interact with the Kubernetes cluster.
- We configure our Pulumi Kubernetes provider instance to communicate with the OpenShift cluster. For this, we rely on kubeconfig, which is assumed to be set up with OpenShift credentials.
- We define a placeholder values object, `deltaSharingServerValues`, that represents the configuration values for the `delta-sharing-server` Helm chart. These values are used to customize the deployment and should be replaced with the actual configuration required by the Helm chart.
- We create an instance of a `Chart` resource. This represents the Helm chart we want to deploy to our OpenShift cluster. Replace `repository-url` and `chart-version` with the actual repository URL and version of the `delta-sharing-server` Helm chart.
- Finally, we export the endpoint of the `delta-sharing-server` service, which makes it possible to access the deployed Helm chart outside of the cluster.

Please replace the placeholder values with actual values relevant to your deployment. Also, make sure that the specified repository where the Helm chart is located is accessible from your OpenShift cluster. If the `default` namespace is not the appropriate namespace for your use case, change it to the namespace where you want to deploy the Helm chart.

Remember to install the Pulumi CLI, configure your cloud provider credentials, and set up your Pulumi project before running this program. After the setup is complete, you can deploy the Helm chart by running `pulumi up`.
