1. Deploy the redis-ui helm chart on Kubernetes

    TypeScript

    To deploy the redis-ui Helm chart on a Kubernetes cluster using Pulumi, we will follow these steps:

    1. Setup Pulumi Kubernetes Provider: We will set up the Pulumi Kubernetes provider to interact with your Kubernetes cluster. This provider will use your currently configured kubeconfig file to deploy the Helm chart to the cluster you are logged into.

    2. Create a Helm Chart Resource: With the provider set up, we will define a Helm chart resource. This resource points to the redis-ui chart, which we assume is available in a public or private Helm chart repository.

    3. Deploy the Helm Chart: Running the Pulumi program will then deploy the redis-ui Helm chart onto your Kubernetes cluster.

    Here is a TypeScript program that accomplishes this:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance using the default kubeconfig credentials. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: "<your-kubeconfig-content>", // Replace <your-kubeconfig-content> with your kubeconfig file content if needed }); // Deploy the redis-ui Helm chart using the Kubernetes provider. const redisUiChart = new k8s.helm.v3.Chart("redis-ui", { // "redis-ui" here is an arbitrary name we assign to the Helm release. repo: "example", // Replace "example" with the actual repository name where the redis-ui chart is located. chart: "redis-ui", // This should match the chart name in the repository. // If you need to specify a particular version, you can add `version: "1.2.3"` in this section. // If you have custom values to pass to the chart, include a `values` section with the relevant key-value pairs. }, { provider: k8sProvider }); // Export the Redis UI service endpoint, if it is exposed via a LoadBalancer service type in your Helm chart. // Make sure to refer to the service definition within the chart to find the correct service name and namespace, if different. export const redisUiEndpoint = k8sProvider.getResourceProperty( "v1/Service", // Resource kind and apiVersion "default", // Namespace where the service is deployed. You might need to change this if your Helm chart deploys it to a different namespace. "redis-ui-redis-ui", // Name of the service deployed by the Helm chart. "status" // Part of the service object we are interested in. ).apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);
    • Replace <your-kubeconfig-content> with the actual contents of your kubeconfig file if your environment necessitates it. Usually, Pulumi uses the default kubeconfig file from your environment, so you might not need to pass it explicitly.
    • The repo field should be updated to match the Helm repository hosting the redis-ui chart.
    • The chart field should be the name of the chart in the Helm repository; in your case, it is redis-ui.
    • You may add a version property to specify a particular chart version.
    • The values section inside the Chart resource allows you to override default values in the Helm chart. For instance, things like image versions, resource limits, or any other value in the Helm chart's values.yaml file can be overridden here.
    • The redisUiEndpoint export is a common pattern used to retrieve the endpoint of a LoadBalancer service. It assumes that the Helm chart deploys a LoadBalancer service named redis-ui-redis-ui in the default namespace.

    To run this Pulumi program:

    1. Ensure you have Pulumi installed on your system and the Pulumi CLI is set up.
    2. Create a new directory, navigate to it in your terminal, and run pulumi new typescript to create a new Pulumi TypeScript project.
    3. Replace the content of index.ts with the code above.
    4. If required, edit the kubeconfig content and Helm chart details in the program.
    5. Run pulumi up to preview and deploy the changes. Confirm the deployment when prompted.

    Pulumi will now deploy the redis-ui Helm chart to the currently active Kubernetes cluster as per your kubeconfig. After the deployment has completed, you can get the LoadBalancer's IP or hostname by running pulumi stack output redisUiEndpoint, which can be used to access the redis-ui application.
