Deploy the orchestra-login-googlews helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an OpenShift cluster using Pulumi, you will need to have access to an OpenShift cluster and have the Helm CLI installed. Also, ensure you have Pulumi installed and set up.

The main steps for deploying a Helm chart include setting up the Pulumi program with the necessary imports, defining the Helm chart resource with its settings, and then running the Pulumi program to perform the deployment.

Here’s a detailed breakdown of how you could set this Pulumi program up in TypeScript:

Import the necessary libraries: You would need to import the Pulumi Kubernetes library to interact with your Kubernetes/OpenShift cluster.
Define the Kubernetes provider: This tells Pulumi how to connect to a specific Kubernetes cluster. If your KUBECONFIG environment variable is already pointing to your OpenShift cluster, the default provider will use that configuration.
Define the Helm chart resource: Using the kubernetes.helm.v3.Chart resource, you can specify the name of the chart, the repository where it is located, and any custom values you want to override in the Helm chart’s values.yaml file.

Let's start by setting up the Pulumi program in TypeScript:

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

// Define the namespace where the Helm chart will be installed.
const namespace = new k8s.core.v1.Namespace("orchestra-namespace", {
    metadata: {
        name: "orchestra"
    }
});

// Get the OpenShift cluster's provider if it is not the default.
// Otherwise, Pulumi will use the current context in your KUBECONFIG.
const provider = new k8s.Provider("openshift-provider", {
    // You can specify the kubeconfig or context here if needed.
    // e.g., kubeconfig: "..."
});

// Deploy the orchestra-login-googlews Helm chart from its repository.
const orchestraChart = new k8s.helm.v3.Chart("orchestra-login-googlews-chart", {
    chart: "orchestra-login-googlews",
    version: "<chart version>", // Specify the version of the chart to be deployed
    namespace: namespace.metadata.name,
    fetchOpts:{
        repo: "https://example.com/charts", // Replace with the actual repository URL of the chart
    },
}, { provider });

// Export the namespace name and the Helm chart status
export const orchestraNamespace = namespace.metadata.name;
export const orchestraChartStatus = orchestraChart.status;

Replace <chart version> with the appropriate chart version you require and https://example.com/charts with the actual URL of the Helm chart repository.

This Pulumi program does the following:

It imports the Pulumi Kubernetes package to work with Kubernetes resources.
It creates a Kubernetes namespace for the Helm chart deployment.
It initializes the provider to connect to an OpenShift cluster.
It deploys the orchestra-login-googlews Helm chart to the specified namespace in the OpenShift cluster.
It exports the namespace and the Helm chart status for reference.

To run this Pulumi program:

Save the above code to a file named index.ts.
Run pulumi up to preview and deploy the changes.
Confirm the deployment to proceed with the actual deployment on your OpenShift cluster.

Remember to have your OpenShift cluster access configured correctly, as Pulumi will need it to perform the deployment.

After running the pulumi up command, Pulumi CLI will communicate with your OpenShift cluster and perform the deployment based on the above program. The output will show the namespace and Helm chart status that you exported. If you encounter any issues, ensure that your OpenShift cluster is accessible and that you have the necessary permissions to deploy resources to it.
