Deploy the business-central-for-sso helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on OpenShift with Pulumi, you need to use the Pulumi Kubernetes provider which enables you to interact with your Kubernetes clusters and to manage the lifecycle of the Kubernetes resources, including deploying a Helm chart. In this case, we'll be using the Helm chart for deploying the Business Central for SSO.

Make sure you have:

An OpenShift cluster where you have permissions to create resources.
kubectl configured to communicate with your OpenShift cluster.
Pulumi CLI installed and set up to manage your resources.

The main components of the deployment are:

Helm Chart: Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade applications using a Helm chart. Helm charts are collections of pre-configured Kubernetes resources.
OpenShift: a Kubernetes distribution from Red Hat, designed for enterprise applications. Pulumi interacts with OpenShift just like any other Kubernetes cluster.

Here's a Pulumi program in TypeScript that uses the @pulumi/kubernetes package to deploy a Helm chart to an OpenShift cluster. The chart we want to deploy is business-central-for-sso, which presumably is a chart that you can access from a Helm repository or a local directory.

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

// Be sure to replace `<namespace>` with the namespace where you would like to deploy your chart,
// and `<repository>` with the URL of the Helm chart repository containing the `business-central-for-sso` chart.
const businessCentralNamespace = new kubernetes.core.v1.Namespace("business-central-namespace", {
    metadata: {
        name: "business-central"
    }
});

const businessCentralChart = new kubernetes.helm.v3.Chart("business-central-for-sso", {
    chart: "business-central-for-sso",
    // If the chart is in a public or private Helm repository, uncomment and set these fields instead.
    // fetchOpts: {
    //     repo: "https://charts.example.com/"
    // },
    // The version of the chart to deploy
    version: "1.0.0",
    // Namespace to deploy the chart into.
    namespace: businessCentralNamespace.metadata.name,
    // Values to pass to the chart.
    values: {
        service: {
            type: "ClusterIP"
        },
        // Add additional values here as needed for your specific chart.
    },
}, { provider: myOpenshiftProvider }); // Replace 'myOpenshiftProvider' with your provider configuration.

// Exports the name of the namespace and status of the helm chart deployment
export const namespaceName = businessCentralNamespace.metadata.name;
export const businessCentralChartStatus = businessCentralChart.status;

Be sure to replace placeholder values in comments with the actual values relevant to your scenario. This includes the Helm repository URL, chart version, namespace, and any custom values you want to provide to the chart.

To run this Pulumi program, you need to have Pulumi installed and set up for TypeScript, and you need to:

Create a new directory for your Pulumi program.
Run pulumi new typescript in that directory to create a new Pulumi TypeScript project.
Replace the contents of index.ts with the code provided above.
Install the required dependencies by running npm install @pulumi/pulumi @pulumi/kubernetes.
Preview the deployment with pulumi preview to see the expected changes.
Deploy your stack with pulumi up to apply changes to your OpenShift cluster.

This program will define a Kubernetes namespace if not provided, and then deploy the business-central-for-sso Helm chart into this namespace. Adjust the chart version and values according to your specific Helm chart's requirements.

You need to input actual names and versions relevant to your Helm chart. Don't forget to set up your OpenShift provider appropriately with the correct KubeConfig or other authentication mechanisms that Pulumi might require to interact with your OpenShift cluster. If you face any issues with the authentication, make sure to consult the OpenShift and Pulumi documentation for the correct configuration.
