Deploy the redpanda-operator helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

Deploying the Redpanda operator Helm chart on Linode Kubernetes Engine (LKE) using Pulumi can be accomplished with the kubernetes provider. We will create a Pulumi TypeScript program that does the following:

Sets up a new Kubernetes provider to interact with the Linode Kubernetes Engine.
Deploys the Redpanda operator Helm chart using the chart details and any necessary configurations.

For this task, we're using the kubernetes.helm.sh/v3.Chart resource, which is a Pulumi resource that allows us to deploy Helm charts onto a Kubernetes cluster. Helm is a package manager for Kubernetes that enables us to deploy applications using preconfigured Helm charts. The Redpanda operator Helm chart will set up Redpanda, which is a streaming data platform for mission-critical workloads.

To get started with this Pulumi program, you'll need a few prerequisites:

Pulumi CLI installed and set up.
Access to a Linode Kubernetes Engine cluster with kubeconfig file obtained from Linode.
Helm CLI installed if you need to customize or inspect the Helm chart locally before deployment.

Below is the detailed Pulumi TypeScript program that deploys the Redpanda operator Helm chart on an LKE cluster:

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

// You must have set up a kubeconfig file that Pulumi can use to access your Linode Kubernetes cluster.
// The kubeconfig file is typically located at "~/.kube/config" or specified in the KUBECONFIG environment variable.
const kubeconfig = "<path-to-your-kubeconfig-file>";

// Create an instance of the Kubernetes provider with the given kubeconfig.
const provider = new k8s.Provider("linode-k8s-provider", { kubeconfig });

// Using the 'kubernetes.helm.sh/v3.Chart' resource from Pulumi to deploy the Redpanda operator Helm chart.
// Replace the '<chart-version>' placeholder with the specific version you want to install, if necessary.
const redpandaOperatorChart = new k8s.helm.v3.Chart("redpanda-operator", {
    // Assuming the chart is available in a public Helm repository, you would include `repo` and `chart` properties.
    // If the Redpanda operator chart is not available in the default Helm repos, specify the correct `repo` here.
    repo: "redpanda", 
    chart: "redpanda-operator",
    version: "<chart-version>", // Specify the version of the chart you want to deploy
    // Include any custom values required for the Redpanda operator chart.
    // The `values` property represents a map of user-supplied values that are passed to the Helm chart.
    values: {
        // Placeholder for potential custom values. Replace with actual values if needed.
        // For example: 
        // replicaCount: 3,
    },
}, { provider });

// Export any properties of the deployed chart that may be useful. For instance, you can export the status of the release.
export const status = redpandaOperatorChart.status;

In the code above, replace "<path-to-your-kubeconfig-file>" with the actual path to your kubeconfig file and "<chart-version>" with the version number of the Redpanda operator Helm chart you wish to deploy.

The values property within the chart is where you can specify any custom values that the Helm chart accepts. These values will override the defaults set by the chart maintainers. In this example, we've left it empty, but you might want to configure it depending on the specific requirements of the Redpanda operator and your application needs.

Once the program is ready, you can deploy it using the following Pulumi CLI commands:

pulumi up - This command creates or updates resources to match the desired state specified in the Pulumi program.
After confirming the deployment, Pulumi will provision the Redpanda operator Helm Chart on your Linode Kubernetes cluster.

Lastly, if you need to learn more about the specific configurations available for the Redpanda operator Helm chart, you should consult the chart's documentation or use the Helm CLI to fetch more details.
