1. Deploy the minio-standalone helm chart on Linode Kubernetes Engine


    To deploy the Minio standalone Helm chart on Linode Kubernetes Engine (LKE), you will be using Pulumi's Kubernetes provider. This allows you to declare Kubernetes resources in a familiar language and deploy them to any Kubernetes cluster.

    Minio is a high-performance, distributed object storage system, designed for large-scale private cloud infrastructure. Helm charts enable you to define, install, and upgrade even the most complex Kubernetes applications.

    Here's a step-by-step guide to deploy the Minio Helm chart to an LKE cluster:

    1. Set up Pulumi with the Linode provider: Ensure you've configured Pulumi to work with Linode, including setting up any necessary tokens or SSH keys.

    2. Create a new Pulumi project: This involves initializing a new project with pulumi new command and choosing TypeScript as the language.

    3. Install the necessary Pulumi packages: You should have the @pulumi/kubernetes package installed to work with Kubernetes resources.

    4. Write the TypeScript code to deploy the Helm chart: You'll use the Chart resource from the @pulumi/kubernetes/helm/v3 package to deploy Minio. You will need to have your LKE kubeconfig file ready to allow Pulumi to interact with your cluster.

    5. Deploy using Pulumi CLI: With the pulumi up command, your code will be deployed to the LKE cluster.

    Here is the TypeScript program that demonstrates how to deploy the Minio standalone Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that uses the kubeconfig from Linode Kubernetes Engine. // Make sure you have your LKE kubeconfig on your local machine const provider = new k8s.Provider("linode-k8s", { kubeconfig: "<YOUR_LKE_KUBECONFIG>", // Replace with the path to your kubeconfig file }); // Deploy the Minio Helm chart using the Chart resource. // Ensure you specify the correct repo or chart URL, version, and any values that configure Minio according to your needs. const minioChart = new k8s.helm.v3.Chart("minio", { chart: "minio", version: "8.0.10", // Specify the version of the Minio chart you want to deploy fetchOpts: { repo: "https://helm.min.io/", // Minio Helm repository URL }, values: { // Custom values for the Minio Helm chart can be specified here. // For example, to set a custom user and password (using secretKeyRef for a real deployment): // accessKey: { secretKeyRef: { name: "minio", key: "access-key" } }, // secretKey: { secretKeyRef: { name: "minio", key: "secret-key" } }, accessKey: "YOUR_ACCESS_KEY", // Replace with a real key secretKey: "YOUR_SECRET_KEY" // Replace with a real key }, namespace: "default", // Specify the namespace where Minio should be deployed }, { provider }); // Export the Minio service endpoint to access it later export const minioServiceEndpoint = minioChart.getResourceProperty("v1/Service", "minio", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    Here's a brief explanation of the code above:

    • We import @pulumi/kubernetes, which is the Pulumi package to work with Kubernetes resources.

    • We create the provider which is an instance of the Kubernetes provider to interact with the LKE cluster. You need to replace <YOUR_LKE_KUBECONFIG> with the actual path to your kubeconfig file.

    • We define a Chart resource named minioChart. The chart property specifies the name of the chart, minio, and version specifies the chart version. The fetchOpts.repo property specifies the URL of the Minio Helm repository.

    • The values property in the chart allows for setting custom configurations. I've added placeholders for accessKey and secretKey. In a production environment, you should store these as Kubernetes secrets and reference them within your Helm chart as shown in the comments.

    • We set the namespace where you want to deploy Minio. In this example, it is the default namespace.

    • Finally, we export minioServiceEndpoint which pulls the hostname or IP where the Minio service will be accessible from outside the cluster.

    To run this program:

    1. Save the above code to a file, e.g., index.ts.
    2. Run pulumi up to create the resources on your LKE cluster.

    Remember to install the Pulumi CLI and have your Linode Kubernetes Engine configured. Once the deployment is successful, you'll get the Minio service endpoint as an output with which you can interact with your Minio instance.
