Deploy the minio-standalone helm chart on Rancher

Question

Pulumi · Accepted Answer

Deploying a Helm chart on Rancher involves a few steps. First, you'll need to have Rancher installed and configured properly to manage your Kubernetes clusters. Once that's set up, you can use Pulumi's Rancher 2 provider to deploy Helm charts into your Rancher-managed clusters.

In this case, we'll deploy the minio-standalone Helm chart, assuming that the chart is available in a reachable Helm repository. The Rancher 2 provider allows us to interact with Rancher in a similar fashion to kubectl for vanilla Kubernetes. To proceed, we will need to use the rancher2.CatalogV2 resource to ensure the Helm repository containing the MinIO chart is known to Rancher, and then use the rancher2.AppV2 to deploy the chart.

The following program is an example of how you would deploy the minio-standalone Helm chart on a Rancher-managed Kubernetes cluster using Pulumi TypeScript:

import * as rancher2 from "@pulumi/rancher2";

// Ensure the Helm chart repository is registered in Rancher
const minioRepo = new rancher2.CatalogV2("minio-helm-repo", {
    clusterId: "<RANCHER-CLUSTER-ID>", // replace with your Rancher cluster ID
    name: "minio-repo",
    repoType: "helm",
    url: "https://helm.min.io/", // MinIO Helm chart repo URL
});

// Deploy the `minio-standalone` Helm chart from the repository
const minioApp = new rancher2.AppV2("minio-standalone", {
    clusterId: "<RANCHER-CLUSTER-ID>", // replace with your Rancher cluster ID
    namespace: "default",
    repoName: minioRepo.name,
    chartName: "minio",
    chartVersion: "<CHART-VERSION>", // specify the version of MinIO chart you want to deploy
    values: `  # Values to configure MinIO
accessKey: "minio"
secretKey: "minio123"
persistence:
  size: "10Gi"
`,  // use `values` field to configure the MinIO Helm chart according to your needs
});

export const minioAppID = minioApp.id;

Here’s what each part does:

CatalogV2: This Pulumi resource represents a Helm chart repository in Rancher. You create a 'CatalogV2' resource with the URL pointing to the MinIO Helm repository, https://helm.min.io/. This allows Rancher to access and list the Helm charts available in this repository.
AppV2: Represents the deployment of an app (Helm chart) in Rancher. You need to specify the cluster ID to tell Rancher which cluster to deploy to, along with the namespace where the app will be deployed. You also link the repository you have registered earlier by referring to its name (minioRepo.name). The chartName field specifies the name of the Helm chart to deploy – in this case, 'minio'. Lastly, you can customize the Helm chart configuration by providing a set of values in YAML format using the values field. These lines of code configure the MinIO deployment with a basic set of credentials and request a persistence volume of 10Gi. Replace <CHART-VERSION> with the specific version number you want to deploy.
minioAppID: An export that shows the unique identifier of the deployed MinIO app, which can be useful for tracking and management purposes.

Before running this Pulumi program, replace <RANCHER-CLUSTER-ID> with your actual Rancher cluster ID where you want to deploy the Helm chart, and <CHART-VERSION> with the version of the MinIO Helm chart that you want to use.

Ensure you have set up your Pulumi environment with the appropriate credentials for interacting with Rancher. After completing this setup, you may run pulumi up to execute the program and deploy MinIO on your Rancher managed cluster.
