Deploy the php-stack helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy a PHP stack Helm chart on DigitalOcean's Kubernetes Service using Pulumi, you'll need to perform a series of steps including creating a DigitalOcean Kubernetes cluster, installing the Helm CLI, and deploying the Helm chart to the cluster. Below I'll provide a comprehensive guide and the Pulumi TypeScript program to help you through this process.
-
Create a DigitalOcean Kubernetes Cluster: The first step is to create a DigitalOcean Kubernetes cluster where your applications will be running.
-
Install Helm CLI: Helm is a package manager for Kubernetes, which simplifies deployment of applications. The Helm CLI is required to manage the Helm charts.
-
Deploy the PHP Stack Helm Chart: Once Helm is set up and the Kubernetes cluster is ready, you deploy the PHP stack using a Helm chart. Helm charts are the packages that contain all the needed resources to deploy an application, or a set of related applications, onto a Kubernetes cluster.
Prerequisites
- Ensure you have Pulumi installed.
- Ensure the Pulumi CLI is configured with your DigitalOcean token.
- Install Node.js and npm if they are not already installed.
- Install the Helm CLI on your system.
Pulumi TypeScript Program
Below is the Pulumi program that performs the required operations to deploy a PHP stack Helm chart on DigitalOcean Kubernetes Service.
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", // Choose the region that is suitable for you version: "latest", // Set the version of Kubernetes you want to use nodePool: { name: "default", size: "s-2vcpu-2gb", // Choose the size that fits your need nodeCount: 2, // The number of nodes in the pool }, }); // Step 2: Use the cluster credentials to configure the Kubernetes provider const provider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the PHP stack using the Helm chart const phpStackChart = new kubernetes.helm.v3.Chart("php-stack", { chart: "php-stack", version: "1.0.0", // Replace with the version of the chart you wish to deploy fetchOpts: { repo: "https://charts.example.com/", // Replace with the actual Helm chart repository URL }, }, { provider: provider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Export the PHP stack service details export const phpStackService = phpStackChart.getResource("v1/Service", "my-php-stack-service");
Explanation
-
DigitalOcean Kubernetes Cluster: The
digitalocean.KubernetesCluster
resource declares a new Kubernetes cluster in your DigitalOcean account with specified parameters like region, version, and node pool configuration. -
Kubernetes Provider: The
kubernetes.Provider
resource is used to interact with the newly created Kubernetes cluster using its configuration. -
PHP Stack Helm Chart: The
kubernetes.helm.v3.Chart
resource deploys a Helm chart into your Kubernetes cluster. You'll need to specify thechart
andversion
of the PHP stack Helm chart you want to deploy, along withfetchOpts.repo
, which should point to the chart's repository URL.Additionally, the
provider
argument ensures that the Helm chart will be deployed to the newly created DigitalOcean Kubernetes cluster. -
Exports: Finally, this code exports the kubeconfig, which is necessary to access the Kubernetes cluster from your local machine using
kubectl
. It also exports service details for the PHP stack, which can be used to access the application.
Post-Deployment Steps
- After running this Pulumi program, the output will provide you with a kubeconfig. Save this as a file to access your cluster using
kubectl
. - To view the services and access your PHP stack, you can use
kubectl get services
with the provided kubeconfig.
Deploying a PHP stack as a Helm chart on DigitalOcean Kubernetes Service with Pulumi is an effective way to manage your cloud native applications, making use of Pulumi's programming model and the powerful packaging of Helm.
