Deploy the minio-directpv helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `minio-directpv` Helm chart on Linode Kubernetes Engine using Pulumi, you'll follow these steps:

1. Set up a new Pulumi project and configure it for use with the Linode Kubernetes Engine.
2. Define the required Linode Kubernetes Engine resources using Pulumi's Linode provider.
3. Deploy the `minio-directpv` chart using Pulumi's Kubernetes provider, which allows you to deploy Helm charts.

In your Pulumi project, you'll set up the Linode Kubernetes Engine (LKE) cluster using the `linode.LKECluster` resource. After the cluster is created, you'll configure Pulumi to use the generated kubeconfig for the Kubernetes provider. Finally, you'll use the `kubernetes.helm.v3.Chart` resource to deploy the `minio-directpv` Helm chart to your LKE cluster.

Below is a TypeScript program that creates a Linode Kubernetes Engine cluster and deploys the `minio-directpv` Helm chart onto it.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as linode from "@pulumi/linode";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Create a Linode Kubernetes Engine (LKE) cluster
const cluster = new linode.LKECluster("my-cluster", {
    // Specify your Linode region
    region: "us-central",
    // Define the Kubernetes version
    k8sVersion: "1.21",
    // Define the node pools for your cluster
    pools: [{
        type: "g6-standard-1",
        count: 1,
    }],
});

// Step 2: Use the generated kubeconfig from the LKE cluster for the Kubernetes provider
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Step 3: Deploy the `minio-directpv` Helm chart using the Kubernetes provider
const minioChart = new k8s.helm.v3.Chart("minio-directpv", {
    // Specify the chart, version, and repository
    chart: "minio-directpv",
    version: "0.1.0", // Replace with the desired version of the chart
    repositoryOpts: {
        repo: "https://linode.github.io/helm-charts/", // Replace with the Helm chart repository URL
    },
    values: {
        // Set Helm chart values here, for example:
        accessKey: "minio",
        secretKey: "minio123",
    },
}, { provider: k8sProvider });

// Export the cluster's kubeconfig and endpoint
export const kubeconfig = cluster.kubeconfig;
export const endpoint = cluster.endpoint;
```

This specific Pulumi program completes the following tasks:

1. It creates a Linode Kubernetes Engine cluster with a single node pool in the `us-central` region and with Kubernetes version `1.21`. You can customize the region, version, and size as per your requirements.

2. It sets up a Kubernetes provider with the kubeconfig of the created LKE cluster.

3. It deploys a Helm chart named `minio-directpv` from the provided Helm chart repository. Make sure the chart version `0.1.0` is what you need; you might need to replace it with the current version. It also provides some example values for the chart — `accessKey` and `secretKey`. You'll want to customize the `values` field with the necessary parameters required for your Minio deployment, such as persistence options, resource constraints, and any configuration relevant to `directpv`.

Ensure you have Pulumi installed, you are authenticated with both Linode and Pulumi, and you have the necessary permissions to create resources in your Linode account. After setting up, you can run this program using `pulumi up` command, which will deploy the resources to Linode and output the cluster's kubeconfig and endpoint that you can use to interact with your cluster.
