Deploy the tyk-dev-portal helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `tyk-dev-portal` helm chart on Linode Kubernetes Engine, you'll need to start by setting up a Kubernetes cluster on Linode. Once the cluster is ready, you can use Pulumi's Kubernetes provider to deploy the Helm chart to the cluster.

Below is a step-by-step guide and a Pulumi TypeScript program that accomplishes this.

### Step 1: Set up Linode Kubernetes Engine Cluster

Before running the Pulumi program, you need to have a Kubernetes cluster set up in Linode. You can do this through the Linode Cloud Manager, Linode CLI, or using Pulumi to script the process. Please ensure you have configured `kubectl` to communicate with your Linode Kubernetes cluster.

### Step 2: Install Pulumi

Ensure you have Pulumi CLI installed on your machine. If you don't have it installed, please visit the [Pulumi Installation Guide](https://www.pulumi.com/docs/get-started/install/).

### Step 3: Create a New Pulumi Project

Create a new directory for your project and inside that directory run `pulumi new typescript`. This command will create a new Pulumi TypeScript project and you'll be prompted to enter project information.

### Step 4: Install Pulumi Kubernetes Package

Inside your new project directory, run `npm install @pulumi/kubernetes` to install the necessary Pulumi Kubernetes package. This will allow you to interact with Kubernetes resources, including Helm charts.

### Step 5: Write the Pulumi Program to Deploy the Helm Chart

Here's the TypeScript program using Pulumi to deploy the `tyk-dev-portal` Helm chart on a pre-existing Linode Kubernetes cluster:

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

// Assuming you have configured your kubectl to interact with Linode Kubernetes cluster.
// This uses the configuration from your kubeconfig file.
const provider = new k8s.Provider("linode_k8s", {
    kubeconfig: kubeconfigContentsOfLinodeCluster, // Replace this with your kubeconfig contents
});

// Deploying the tyk-dev-portal chart from Helm repository
const chart = new k8s.helm.v3.Chart("tyk-dev-portal", {
    // Your chart configuration goes here
    // This is an example placeholder, ensure to replace `repo` and `chart` with actual values
    chart: "tyk-dev-portal",
    version: "chart-version", // specify the version of the chart
    fetchOpts:{
        repo: "https://helm.tyk.io/public/helm/charts/", // the repository URL where the chart is hosted
    },
    // If the chart requires custom values, define them here
    values: {
        // Provide configuration required for tyk-dev-portal as key-value pairs
    },
}, { provider });

// Export any important information regarding the deployment
export const chartName = chart.metadata.name;
```

Replace `kubeconfigContentsOfLinodeCluster` with your actual kubeconfig file contents and adjust the `chart`, `repo`, and `values` as needed for your setup. This program assumes you're using the correct Helm chart repository and chart name for the Tyk Developer Portal.

### Step 6: Deploy the Helm Chart

Run the following commands in your Pulumi project directory:

```sh
pulumi up
```

This command will execute your Pulumi program and deploy the `tyk-dev-portal` chart onto your Linode Kubernetes Engine.

### Step 7: Verify the Deployment

After deployment, you can check the status of your Helm release using `kubectl` or by visiting the Linode Cloud Manager.

For instance, you can run:

```sh
kubectl get svc,deploy,pods -l app.kubernetes.io/name=tyk-dev-portal
```

This will show you the services, deployments, and pods related to the `tyk-dev-portal` application that you just deployed.

Remember, the Linode Kubernetes Engine (LKE) might have specific requirements or configurations. Make sure you review the Helm chart values and customization options to ensure they are compatible with the LKE environment and your requirements.
