Deploy the svn-git-sync helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy the
svn-git-sync
Helm chart on the Digital Ocean Kubernetes Service, we'll break the task into two parts:- Create a Kubernetes cluster on Digital Ocean using Pulumi's
digitalocean.KubernetesCluster
resource. - Deploy the
svn-git-sync
Helm chart to the cluster using thekubernetes.helm.v3.Chart
resource.
We'll use Pulumi's TypeScript language for the code example below. To start, you'll need to set up Pulumi with Digital Ocean and have Node.js and TypeScript installed. Use
npm
to install the required Pulumi packages for Digital Ocean and Kubernetes.Now let's walk through the Pulumi program:
Step 1: Import Required Packages
We import packages for both the Digital Ocean and Kubernetes providers. These providers allow us to interact with Digital Ocean to create a Kubernetes cluster and with the Kubernetes API to deploy Helm charts.
Step 2: Create a Digital Ocean Kubernetes Cluster
Using the
digitalocean.KubernetesCluster
resource, we define the specifications for our Kubernetes cluster. This resource enables us to define the region, version, node pool configuration, etc.Step 3: Deploy the
svn-git-sync
Helm ChartOnce the Kubernetes cluster is set up, we'll use the
kubernetes.helm.v3.Chart
resource to deploy thesvn-git-sync
Helm chart. We need to specify the repository where the Helm chart is located (if it's not in a public repository like Helm Hub), the chart's name, and any custom values you want to override in the chart'svalues.yaml
file.Here's a Pulumi program in TypeScript that does exactly that:
import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // A Digital Ocean token is needed to authenticate the actions with your account const digitalOceanToken = new pulumi.Config().require("digitalOceanToken"); // Step 1: Provide the required Digital Ocean token for authentication const provider = new digitalocean.Provider("do-provider", { token: digitalOceanToken, }); // Step 2: Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "latest", nodePool: { size: "s-1vcpu-2gb", name: "default", nodeCount: 2, }, }, { provider: provider }); // Step 3: Initialize the Kubernetes provider using the created cluster kubeconfig const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 4: Deploy the 'svn-git-sync' Helm chart const svnGitSync = new k8s.helm.v3.Chart("svn-git-sync-chart", { chart: "svn-git-sync", // Replace with the actual chart name if different // Assuming the chart is located at a specific Helm repository, you must add the 'repo' attribute here // repo: "https://example.com/helm-charts", values: { // Custom values for the 'svn-git-sync' Helm chart go here // Example: // replicaCount: 2, }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the service's public IP export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const servicePublicIp = svnGitSync.getResourceProperty("v1/Service", "svn-git-sync-service", "status").apply(status => status.loadBalancer.ingress[0].ip);
The Pulumi program consists of the following parts:
- The Digital Ocean provider is configured with your Digital Ocean API token.
- A Kubernetes cluster is instantiated in the
nyc1
region with an appropriate node size and count. Adjust these values as per your requirements. - A Kubernetes provider is initialized with the kubeconfig obtained from the Digital Ocean cluster. This allows Pulumi to interact with your Kubernetes cluster.
- The
svn-git-sync
Helm chart is deployed to the Kubernetes cluster. You may need to replace"svn-git-sync"
with the actual chart name and therepo
attribute with the URL of the Helm repository. You can also specify any custom values that you need to configure for your deployment.
After defining the resources, we export the kubeconfig, which you can use to interact with the cluster with
kubectl
, and the service's public IP address, which lets you access the deployed service if it is exposed as a LoadBalancer.Remember to replace placeholders like
digitalOceanToken
with the actual values for your setup. Ensure that your Helm chart name and repository is correct and that it contains thesvn-git-sync
chart you wish to deploy.To deploy this Pulumi program, save the code to a file named
index.ts
in a new directory, then runpulumi up
. Follow the prompts that Pulumi gives you to preview and apply the changes, which will create the cluster and deploy the Helm chart.- Create a Kubernetes cluster on Digital Ocean using Pulumi's
