1. Deploy the redis-setup helm chart on Opensshift


    To deploy the redis-setup Helm chart on an OpenShift cluster using Pulumi, you’ll need to use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package. This resource enables you to deploy Helm charts into a Kubernetes cluster.

    Below is a program written in TypeScript that can be used to deploy a Helm chart to an OpenShift cluster using Pulumi. Ensure that you have configured Pulumi to use your OpenShift cluster's kubeconfig file so that Pulumi can access your cluster.

    First, you need to make sure you have the requisite dependencies installed:

    • @pulumi/pulumi: The core Pulumi SDK.
    • @pulumi/kubernetes: Provides the Kubernetes resources for Pulumi.

    You can install them using npm:

    npm install @pulumi/pulumi @pulumi/kubernetes

    Next, here's the Pulumi program that deploys the redis-setup Helm chart:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; const redisChart = new k8s.helm.v3.Chart('redis-setup', { // Specify the chart repository, name and version repo: 'bitnami', chart: 'redis', version: 'X.Y.Z', // Replace with the desired version of the redis-setup chart namespace: 'default', // Specify which namespace the chart should be installed into values: { // Provide configuration values for the redis Helm chart // These values will override the default values of the chart usePassword: false, cluster: { enabled: true, slaveCount: 2, }, // More values can be added as per your chart's requirements }, }, { provider: /* a k8s.Provider referencing your OpenShift cluster */ }); export const redisChartStatus = redisChart.status;


    • We begin by importing the required Pulumi modules for the Kubernetes resource types.
    • We create a new instance of Chart from the @pulumi/kubernetes/helm/v3 module, which represents a Helm chart deployment in Pulumi.
    • The repo field denotes the name of the repository where the chart is hosted; in this case, we are using the Bitnami repository.
    • The chart field specifies the name of the chart that we want to deploy. Replace 'redis' with 'redis-setup' if that's the exact name of the chart.
    • The version field should specify the exact chart version you wish to deploy.
    • In the namespace field, change 'default' to the desired namespace where you want the chart to be installed in your OpenShift cluster.
    • The values field is a map where you can specify the values that the Helm chart accepts, allowing you to customize the configuration of the Redis instance to suit your needs.
    • The provider option allows you to specify an instance of k8s.Provider configured to use kubeconfig with access to your OpenShift cluster.

    Note: Make sure to replace X.Y.Z with the actual version of the Redis Helm Chart, and update any values according to your chart's requirements or your desired configuration.

    Lastly, you could run your Pulumi program using:

    pulumi up

    This command line will start the deployment process managed by Pulumi. Once the process is finished, it will output the current status of the deployed chart.

    Keep in mind that this is a basic example of deploying a Helm chart to your OpenShift cluster and does not include some OpenShift-specific features or security contexts. Depending on your cluster configuration and security policies, you might need to adjust RBAC settings or pass additional parameters to your Helm chart to ensure proper functioning within OpenShift.
