1. Deploy the redis-setup helm chart on Rancher


    To deploy a Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would need to have the Rancher2 Pulumi provider set up. The Rancher2 provider allows you to interact with resources within a Rancher environment, such as managing Kubernetes clusters, deploying workloads, and installing applications via Helm charts.

    Below is a TypeScript program that demonstrates how to deploy a Redis Helm chart on a Rancher-managed Kubernetes cluster using Pulumi. The program uses the CatalogV2, Namespace, and AppV2 resources to install a Helm chart into a Rancher cluster.

    Let me walk you through the process:

    1. Setup Pulumi: You'll need to have Pulumi installed and configured to work with your chosen cloud provider. This program assumes that you have already configured Pulumi to work with the Rancher2 provider.

    2. Installation of Catalog: Before you can deploy a Helm chart, you typically need to add a Helm chart repository to the cluster's catalog. In this case, we use the CatalogV2 resource to install a catalog that contains the Redis chart. You'll need to provide the URL to the Helm chart repository that you intend to use.

    3. Creation of Namespace: Workloads in Kubernetes are typically deployed within a namespace, which is a way of isolating them within the cluster. We use the Namespace resource to ensure that the namespace we want to deploy Redis into exists.

    4. Deployment of Chart: Lastly, we deploy the Redis chart using the AppV2 resource, which allows us to specify the chart name, version, and values corresponding to the Helm chart we wish to install.

    Here's what the Pulumi TypeScript program looks like:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Initialize a Pulumi program with the Rancher2 provider. const config = new pulumi.Config(); const rancherClusterId = config.require("rancherClusterId"); // The Rancher Cluster ID where you want to deploy Redis. // Create a Catalog to include the repository that has your Redis Helm chart. const catalog = new rancher2.CatalogV2("redisCatalog", { clusterId: rancherClusterId, url: "https://charts.bitnami.com/bitnami", // The Helm chart repository URL. Replace if necessary. gitBranch: "master", // The default branch to clone the chart from, ensure this matches the chart repo's branch. annotations: { "field.cattle.io/description": "A catalog for Redis Helm charts", // A description field for the catalog. }, }); // Create a Namespace for Redis if it does not already exist. const redisNamespace = new rancher2.Namespace("redisNamespace", { clusterId: rancherClusterId, name: "redis-setup", // Adjust the namespace name as per your needs. annotations: { "field.cattle.io/description": "A namespace for running Redis", // A description for the namespace. }, }); // Deploy the Redis Helm chart within the created namespace. const redisApp = new rancher2.AppV2("redisApp", { clusterId: rancherClusterId, namespace: redisNamespace.name, repoName: catalog.name, chartName: "redis", // The name of the chart within the catalog. chartVersion: "14.6.1", // Specify the version of the chart you wish to deploy. values: pulumi.output({}), // Use a config map or a string containing the values.yaml content. // If needed, populate `values` with configurations that are specific to your Redis deployment. }); // Export the Redis App ID for reference export const redisAppId = redisApp.id;

    In this program, the required resources are set up to deploy the Redis Helm chart to the desired namespace in the Rancher-managed Kubernetes cluster. You need to customize the rancherClusterId and the chartVersion based on the available chart versions in the repository you're using. Also, if you have specific configurations for the Redis Helm chart, you may provide them via the values field in the redisApp resource.

    Make sure to replace the placeholders and configuration values with the appropriate information for your setup. After tailoring the code to your requirements, you can run it by executing pulumi up using the Pulumi CLI. This will initiate the deployment process, and you can follow the progress in the console output.
