Deploy the saleor-helm helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Saleor Helm chart on DigitalOcean Kubernetes Service (DOKS), we will follow the steps below:

Set up a DigitalOcean Kubernetes Cluster: We'll first create a DOKS cluster where our Saleor application will live.
Deploy the Helm Chart: Once we have our Kubernetes cluster, we will deploy the Saleor Helm chart into the cluster.

Prerequisites

Before you run the Pulumi program make sure you have the following:

Pulumi CLI installed.
DigitalOcean API token configured with Pulumi using the command pulumi config set digitalocean:token YOUR_TOKEN_HERE --secret.
Helm CLI installed to fetch charts.
kubectl CLI installed to interact with Kubernetes.

Pulumi Program

Below is a TypeScript Pulumi program that illustrates how to create a Kubernetes cluster on DigitalOcean and then deploy the Saleor Helm chart into that cluster. Make sure to replace placeholders like <Your Saleor Helm Chart Version> with actual values.

import * as digitalocean from "@pulumi/digitalocean";
import * as kubernetes from "@pulumi/kubernetes";

// Step 1: Create a DigitalOcean Kubernetes Cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1",
    version: "1.21.5-do.0",
    nodePool: {
        size: "s-2vcpu-2gb",
        nodeCount: 2,
    },
});

// Export the Kubernetes config to access the cluster using `kubectl`.
export const kubeConfig = cluster.kubeConfigs[0].rawConfig;

// Step 2: Deploy Saleor Helm Chart to the DigitalOcean Kubernetes Cluster
const saleorChart = new kubernetes.helm.v3.Chart("saleor-helm-chart", {
    namespace: "default",
    chart: "saleor",
    version: "<Your Saleor Helm Chart Version>",
    fetchOpts: {
        repo: "https://charts.saleor.com/",
    },
}, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig: kubeConfig }) });

// Export the Helm chart resources.
export const saleorChartResources = saleorChart.resources;

Explanation

Here's what each part of the program does:

DigitalOcean Kubernetes Cluster: We create a Kubernetes cluster named do-cluster on DigitalOcean. We specify the region as nyc1, set the Kubernetes version, and define a node pool with specific CPU and memory configurations.
Exporting kubeConfig: We export the raw Kubernetes config to connect to the cluster. This config can be used by kubectl or any Kubernetes client to interact with the cluster.
Saleor Helm Chart: We define a Helm chart resource. This will tell Pulumi to deploy the saleor Helm chart with the specified version. The fetchOpts property includes the repository URL where the chart is located.
Helm Provider with kubeconfig: We create a Kubernetes provider to interact with the cluster. We pass the kubeconfig we exported from our DigitalOcean cluster.
Exporting Saleor Chart Resources: We export the resources defined by the Saleor Helm chart so you can see the details of the Kubernetes resources that were created.

Using the Program

To use this program, save it as index.ts in a Pulumi project directory. Then, run pulumi up to create the cluster and deploy Saleor. After the deployment, Pulumi will output the resources that were created. You can use kubectl with the exported kubeConfig to manage your Kubernetes cluster and applications.

Remember to replace placeholders in the code with the correct values, such as the version of the Saleor Helm chart.
