Deploy the infinispan helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Infinispan Helm chart on an OpenShift cluster using Pulumi, you'll want to use the `kubernetes.helm.v3.Chart` resource from Pulumi's Kubernetes provider. The `Chart` resource allows you to deploy Helm charts to a Kubernetes cluster, which is compatible with OpenShift.

First, you need to have access to an OpenShift cluster and have `kubectl` configured to communicate with your cluster. Ensure you have the proper permissions to deploy services in your intended namespace.

Below is the Pulumi TypeScript program that deploys the Infinispan Helm chart:

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

// Create an instance of the Infinispan Helm chart in the default namespace.
// Note that for OpenShift, depending on your setup, additional configuration may be necessary.
const infinispanChart = new k8s.helm.v3.Chart("infinispan", {
    // Specify the chart repository and name
    chart: "infinispan",
    version: "X.Y.Z", // Replace with the desired chart version
    fetchOpts: {
        // This is where you specify the repository containing the Infinispan Helm chart
        repo: "https://infinispan.org/helm-charts/",
    },
    // In case the Infinispan chart requires some custom values, specify them here:
    values: {
        // These are example custom values; actual values depend on Infinispan Helm chart configuration
        // service: {
        //     type: "NodePort",
        //     port: 11222,
        // },
        // Configure additional chart values such as persistence settings, resource limits, etc.
    },
    // OpenShift-specific configurations, if needed (such as security context, scc policies, etc.)
    // These should be adjusted according to the requirements of your OpenShift installation
    transformations: [
        // For example, manipulating labels or annotations of the resources created by this Helm chart
        (obj: any) => {
            // Manipulate the object as required for OpenShift, for example:
            // if (obj.kind === "Deployment") {
            //     obj.metadata.annotations = obj.metadata.annotations || {};
            //     obj.metadata.annotations["some-annotation"] = "some-value";
            // }
        }
    ],
}, { provider: openShiftProvider }); // Assumption is `openShiftProvider` has been configured

// Export the Chart name
export const chartName = infinispanChart.metadata.name;
```

This program assumes you have set up a provider for OpenShift that is not shown here. If you need to create a new provider configuration for OpenShift, you can refer to Pulumi's Kubernetes provider documentation to configure it before deploying the chart.

Please replace `"X.Y.Z"` with the exact version of the Infinispan Helm chart you wish to deploy. Check the [Infinispan Helm chart repository](https://infinispan.org/helm-charts/) to find the latest version and additional configuration options you might need.

Notice the use of the `transformations` array in the chart definition. This is an optional argument where you can include functions that modify the resources created by the Helm chart to ensure they are compliant with OpenShift-specific requirements.

Remember to install the required Pulumi packages by running:

```shell
npm install @pulumi/kubernetes
```

To run the Pulumi program, execute the following commands:

```shell
pulumi up
```

This will preview and deploy your changes. You will be prompted to confirm the deployment after reviewing the changes that will be made.
