Deploy the scaleway-csi helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Scaleway Container Storage Interface (CSI) Helm chart on an OpenShift cluster, we'll use Pulumi's Kubernetes provider to interact with the cluster and manage Kubernetes resources such as Helm charts. This process involves the following steps:

Setting up the Pulumi project and installing necessary dependencies.
Writing the TypeScript code to deploy the Scaleway CSI Helm chart.
Initializing the Pulumi stack and applying the deployment using Pulumi CLI.

Firstly, you need to have Pulumi installed and set up on your local machine along with kubectl configured to connect to your OpenShift cluster. Make sure you have access to the cluster where you'll be deploying the Helm chart.

Next, we will write a TypeScript program with Pulumi. For this deployment, we'll use Pulumi's Helm Release resource which allows us to deploy Helm charts into a Kubernetes cluster. The kubernetes.helm.v3.Release resource will be used for deploying the Scaleway CSI Helm chart.

Below is a simplified description and the corresponding Pulumi code that deploys the Scaleway CSI Helm chart to an OpenShift cluster:

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

// A name for the Helm release
const releaseName = "scaleway-csi";

// Specify the settings for the Helm Release
const scalewayCsiChart = new k8s.helm.v3.Release(releaseName, {
    chart: "scaleway-csi",
    version: "<CHART_VERSION>", // Specify the chart version
    repositoryOpts: {
        repo: "<HELM_REPO_URL>", // Specify the URL of the Helm chart repository that contains Scaleway CSI
    },
});

// Export the name of the namespace that the Helm chart was deployed into.
export const namespaceName = scalewayCsiChart.status.namespace;

In this code:

We import the @pulumi/kubernetes package to interact with the Kubernetes API within our Pulumi program.
We create a Pulumi resource of type k8s.helm.v3.Release, which corresponds to a Helm release on your OpenShift cluster.
The chart field specifies the name of the chart we want to deploy, scaleway-csi in this case.
The version field is where you would specify which version of the Helm chart you want to deploy. Replace <CHART_VERSION> with the appropriate chart version.
The repositoryOpts field contains options for specifying the Helm chart repository's details. Replace <HELM_REPO_URL> with the repository URL where the Scaleway CSI chart is hosted.
Finally, we export the namespace in which the Helm chart is deployed as a Pulumi stack output.

Please note that you will need to replace <CHART_VERSION> and <HELM_REPO_URL> with specific values for the Scaleway CSI Helm chart. You can usually find this information in the documentation for the helm chart or on the artifact hub where the chart is hosted.

Finally, once you have the program ready:

Run pulumi up from your command line in the directory where your Pulumi TypeScript program, index.ts, is located. This command will provision the resources as described in the code.
Pulumi CLI will show you a preview of the resources being created. Upon confirmation, it will reach out to the OpenShift cluster and deploy the chart.
After the successful deployment, Pulumi will output any stack exports you defined in the code, such as the namespace name in the above example.

Remember to check the chart repository for specific configuration parameters for the Scaleway CSI chart, which you can include in the values property of the Release resource as needed.
