Deploy the service-mesh-operator helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy the
service-mesh-operator
Helm chart on DigitalOcean Kubernetes Service, you'll need to take the following steps within a Pulumi program:-
Set up a DigitalOcean Kubernetes Cluster: You will create a DigitalOcean Kubernetes cluster where your service mesh operator will be deployed.
-
Deploy the Helm Chart: Once you have your Kubernetes cluster set up, you'll use Pulumi's Helm chart support to deploy the
service-mesh-operator
.
Below is a detailed Pulumi program written in TypeScript that accomplishes these two steps. I will guide you through the necessary Pulumi resources and explain why they are used.
Pulumi Program for Deploying Helm Chart on DigitalOcean
First, make sure you have Pulumi installed and have authenticated with DigitalOcean's API. You will also need to have
kubectl
installed to interact with the cluster.import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: '1.21.5-do.0', nodePool: { name: 'default-pool', size: 's-1vcpu-2gb', // Choose the size that is appropriate for your workload nodeCount: 2, // You can specify the number of nodes here }, }); // Once the cluster is created, we can create a Kubernetes Provider that uses the kubeconfig from our new cluster const k8sProvider = new k8s.Provider('do-k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Now, deploy the service-mesh-operator Helm chart using the Kubernetes provider const serviceMeshOperatorChart = new k8s.helm.v3.Chart('service-mesh-operator', { chart: 'service-mesh-operator', // Specify the Helm repository URL if the chart is not in the default repo fetchOpts: { repo: 'https://helmrepo.example.com/', // Replace with the actual Helm repo URL }, // Values to pass to the Helm chart values: { // ... Add necessary custom values for your service mesh operator }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and public endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;
Explanation:
-
DigitalOcean Kubernetes Cluster:
digitalocean.KubernetesCluster
is a resource that provisions a new cluster on DigitalOcean. We define a node pool with a specific Droplet size suitable for our workload and the number of nodes we want in our cluster. -
Kubernetes Provider: The
k8s.Provider
represents a specific Kubernetes cluster where Helm charts and other Kubernetes resources can be deployed. It uses the kubeconfig of the cluster we just provisioned to interact with it. -
Service Mesh Operator Helm Chart: The
k8s.helm.v3.Chart
resource is used to deploy Helm charts. Here we are deploying theservice-mesh-operator
chart from a specified Helm repository (replace therepo
URL with the actual repository where your chart is located). -
Exports: Lastly, exporting the kubeconfig and the Kubernetes endpoint allows you to interact with your cluster using
kubectl
after the Pulumi program completes its execution.
To run this code, save it in a TypeScript file (for example,
index.ts
), and then execute it with Pulumi CLI commands:pulumi up
This command will prompt you to confirm the deployment after showing a preview. Once confirmed, Pulumi will provision the resources as defined.
Remember to replace the placeholder values such as the Helm repository URL (
https://helmrepo.example.com/
) with the actual values that apply to your deployment scenario. If the service mesh operator chart requires additional custom values, you can specify them in thevalues
object within thek8s.helm.v3.Chart
resource.After you've successfully deployed the Helm chart, you can manage your DigitalOcean Kubernetes Service and the service mesh operator using
kubectl
with the exported kubeconfig file.-
