Deploy the glance helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy the Glance Helm chart on Digital Ocean Kubernetes Service, we will first set up a Kubernetes cluster on Digital Ocean. Once we have the cluster running, we will deploy the Glance Helm chart to the cluster.
Here is how we can accomplish this using Pulumi with TypeScript:
-
Setting up a Digital Ocean Kubernetes Cluster: We will use the
digitalocean.KubernetesCluster
resource to create a new Kubernetes cluster in the Digital Ocean cloud. -
Deploying the Glance Helm Chart: After the cluster is up and running, we will deploy the Glance Helm chart using the
kubernetes.helm.sh/v3.Chart
resource from the Pulumi Kubernetes provider. This resource allows us to deploy Helm charts within our Kubernetes cluster.
Let's break down the code step-by-step.
First, we will install the necessary Pulumi packages. The Digital Ocean Kubernetes cluster creation requires the
@pulumi/digitalocean
package, and for deploying Helm charts, we need the@pulumi/kubernetes
package. You can install these packages using npm or yarn:npm install @pulumi/digitalocean @pulumi/kubernetes
Now let's take a look at the Pulumi program:
import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Set up a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "latest", // specify the desired version string or use "latest" nodePool: { name: "default", size: "s-2vcpu-2gb", // this is a basic node size, you can select according to your needs nodeCount: 2, // the number of nodes in the cluster }, }); // Step 2: Deploy the Glance Helm chart to the cluster // Initialize a Kubernetes provider configured to the newly created cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the Glance Helm chart using the Kubernetes Helm Chart resource const glanceChart = new k8s.helm.v3.Chart("glance", { chart: "glance", // You would need to specify the repo or a local path to the chart if it's not a stable chart that Helm already knows about. // For example: repo: "https://charts.example.com/" // Ensure you have the correct repository and chart name for Glance. version: "1.0.0", // specify the chart version namespace: "default", // specify the namespace if needed, defaults to "default" }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the Helm chart name export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const glanceChartName = glanceChart.metadata.apply(meta => meta.name);
In the program above:
- We create a Digital Ocean Kubernetes cluster with the name "do-cluster". The node size is set to a basic one, and we deploy 2 nodes. You can adjust the size and the number of nodes according to your requirements.
- We then declare a new
k8s.Provider
, which is configured using the kubeconfig from the created cluster. This provider is used to interact with the Digital Ocean Kubernetes cluster to manage resources. - Using the Kubernetes provider, we create a new Helm Chart resource, which deploys the Glance Helm chart to the Digital Ocean Kubernetes cluster. Make sure to use the correct repository and chart name for Glance.
- Lastly, we export the raw kubeconfig of the Digital Ocean Kubernetes cluster and the name of the deployed Glance Helm chart.
With this Pulumi program, you will have a Digital Ocean Kubernetes cluster with the Glance Helm chart deployed on it. Just run
pulumi up
to apply the program, and it will provision the infrastructure and deploy the Helm chart as defined. Ensure you have set up your Digital Ocean access token and Pulumi CLI before running the program.-
