Deploy the sns-connector helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on OpenShift typically involves a few steps, including accessing your OpenShift cluster, and then using Helm commands to deploy your desired chart. Since OpenShift is a Kubernetes distribution, the kubernetes package from Pulumi can facilitate this. The kubernetes.helm.v3.Chart resource is a high-level resource that allows you to deploy Helm charts.

Before you get started, ensure that you have the following prerequisites in place:

An existing OpenShift cluster
Pulumi CLI installed
Kubernetes CLI (kubectl) configured to access your OpenShift cluster
Helm CLI installed and configured (if needed for fetching the chart)

Below, you'll find a Pulumi TypeScript program that will deploy a Helm chart named sns-connector, assuming the chart is available in a Helm repository. We will define the Helm repository and specify any necessary configurations.

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

// Define the Helm Chart version, name, and repository URL
const chartVersion = "<INSERT_CHART_VERSION>"; // Set the chart version you want to deploy
const chartName = "sns-connector";
const chartRepoUrl = "<INSERT_REPO_URL>"; // The Helm repository URL where the sns-connector chart is hosted

const snsConnectorRelease = new k8s.helm.v3.Chart(chartName, {
    // Replace <YOUR_NAMESPACE> with the namespace where you want the chart to be deployed
    namespace: "<YOUR_NAMESPACE>",
    chart: chartName,
    version: chartVersion,
    fetchOpts: {
        repo: chartRepoUrl, // The repository URL from which to fetch the chart
    },
    // If the Helm chart requires values, specify them in the 'values' field
    values: {
        // Any required chart values can be defined here
        // For example:
        // replicaCount: 2,
        // service: {
        //   type: "ClusterIP"
        // },
        // You will need to get the appropriate values from the sns-connector chart documentation or values.yaml file
    },
}, { dependsOn: [/* any dependencies to wait for before deploying the chart */] });

export const snsConnectorReleaseName = snsConnectorRelease.status.name;

Replace <INSERT_CHART_VERSION> with the version of sns-connector Helm chart you want to deploy. If you don't specify a version, Helm will deploy the latest one available. Replace <INSERT_REPO_URL> with the URL of the Helm repository where your chart is hosted.

Also, in the values field, you can customize the deployment by specifying the values that align with your chart's values.yaml file. For instance, you might need to configure certain parameters like replicaCount, service types, and so forth.

After replacing the placeholders with actual values and running the program, Pulumi will invoke the Helm CLI to deploy sns-connector on your OpenShift cluster.

Please note: This script does not include OpenShift-specific configurations such as security context constraints, route configuration, or other OpenShift-specific resources. If the Helm chart requires OpenShift-specific settings, you would need to modify the chart values or handle these configurations separately using Pulumi's OpenShift or Kubernetes resources.
