1. Deploy the minio-standalone helm chart on Opensshift


    To deploy the MinIO standalone Helm chart on OpenShift, we'll use Pulumi's Kubernetes provider. The kubernetes.helm.v3.Chart resource allows us to deploy a Helm chart as part of our Pulumi application. Helm charts are a great way to bundle Kubernetes resources and MinIO is a popular object storage solution that can be easily deployed with its Helm chart.

    Below is a program written in TypeScript that shows how to deploy the MinIO Helm chart on an OpenShift cluster. This program assumes you have an OpenShift cluster configured and that your kubeconfig is set up correctly to connect to your cluster.

    Here's the step-by-step process and code:

    1. Install the necessary Pulumi package, if you have not done so already. The package required for Kubernetes is @pulumi/kubernetes.

    2. Import the Pulumi Kubernetes package in your TypeScript program.

    3. Create a new instance of kubernetes.helm.v3.Chart, specifying the name you wish to assign to the Helm chart (minio in this example), the chart repo (usually a URL where the chart is hosted), and any values you wish to override.

    4. Optionally, you can provide the namespace parameter if you want to deploy the Helm chart in a specific namespace.

    Now, let's see how this looks in code:

    import * as k8s from "@pulumi/kubernetes"; // Create a MinIO Helm chart resource in the "default" namespace. const minioChart = new k8s.helm.v3.Chart("minio", { // Usually MinIO Helm chart is available in its own repository, // so you would add that repository to your Helm repos separately // and then specify the chart name here. // For this example, assuming you have already added the MinIO repository // as "minioRepo", the chart should be named "minio/minio". chart: "minio/minio", version: "latest", // Specify the chart version you wish to deploy. // Define the values to be overwritten. // Refer to the MinIO chart for the available options. values: { accessKey: 'YOUR_MINIO_ACCESS_KEY', // Replace with your desired access key. secretKey: 'YOUR_MINIO_SECRET_KEY', // Replace with your desired secret key. // ...include other customization values as needed... }, // Ensure you're deploying the chart into an OpenShift project (namespace). namespace: "default", // Change to a different namespace if needed. // You may need additional configurations depending on your OpenShift setup // and the MinIO chart's requirements. }); // Export the MinIO service URL so we can easily access it. export const minioServiceUrl = minioChart.getResourceProperty("v1/Service", "minio-minio-svc", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    In the above program:

    • chart specifies the name of the chart. It should be noted that you'll need to add the MinIO Helm chart repository to your Helm configuration and reference the chart with minio/minio.
    • values allows us to configure the chart's parameters. You should replace 'YOUR_MINIO_ACCESS_KEY' and 'YOUR_MINIO_SECRET_KEY' with the actual values you'd prefer to use for your MinIO deployment. There are many other parameters you might want to override, which can be found in the chart's documentation.
    • namespace is set to "default". This is where your chart will be installed. Make sure to change it if you have a particular project or namespace where you want to deploy MinIO.
    • minioServiceUrl exports the endpoint of the MinIO service. Once the service is up and running, you can use this URL to interact with your MinIO instance.

    Please note that for a real-world deployment, you should manage sensitive data like accessKey and secretKey with secret management tools like Kubernetes Secrets, and you should not hard-code them into your Pulumi program.

    After writing the code, you would run pulumi up in your CLI to start the deployment. If everything is set up correctly, Pulumi will deploy the MinIO Helm chart to your OpenShift cluster.
