Deploy the devlake helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy the DevLake Helm chart on DigitalOcean Kubernetes Service using Pulumi, we need to achieve the following steps:
- Create a DigitalOcean Kubernetes cluster.
- Deploy the DevLake Helm chart to the cluster.
To begin, we will use the
digitalocean.KubernetesCluster
resource to create a new DigitalOcean Kubernetes cluster, and then we will use thekubernetes.helm.v3.Chart
resource from the Pulumi Kubernetes provider to deploy the DevLake Helm chart to our newly created cluster.Below is a detailed Pulumi TypeScript program that accomplishes these tasks:
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: "nyc3", // Select the region (e.g., New York 3) version: "1.21.5-do.0", // Specify the version of Kubernetes nodePool: { name: "default-pool", size: "s-2vcpu-2gb", // Select the size of the nodes (e.g., 2vCPU, 2GB RAM) nodeCount: 2, // Number of nodes in the node pool }, }); // Export the kubeconfig, which can be used to access the Kubernetes cluster export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Provide the DigitalOcean Kubernetes cluster kubeconfig to the provider const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the DevLake Helm chart to the Kubernetes cluster const devlakeChart = new k8s.helm.v3.Chart("devlake-chart", { chart: "devlake", // This should be the name of the chart in the Helm registry version: "0.1.0", // Replace with the correct chart version fetchOpts: { repo: "https://helm.devlake.io", // Use the correct Helm chart repository URL }, }, { provider: k8sProvider }); // Provide the Helm chart deployment URL if needed export const devlakeChartUrl = pulumi.interpolate`https://${cluster.id}.${cluster.region}.k8s.ondigitalocean.com`;
In this program, we first define a DigitalOcean Kubernetes cluster with
digitalocean.KubernetesCluster
. We specify the region, Kubernetes version, and details of our node pool, including the size and count of the nodes.Next, we export the generated
kubeconfig
for the cluster, which allows us to interact with the cluster usingkubectl
or any Kubernetes-compatible tool.With the Kubernetes cluster in place, we then declare a Pulumi Kubernetes provider,
k8s.Provider
, passing thekubeconfig
so that it knows how to communicate with our cluster.Finally, we deploy the DevLake Helm chart using
k8s.helm.v3.Chart
, specifying the name of the chart, its version, and the chart's repository URL. You will need to replace"devlake"
andversion
with the specific name and version of the DevLake chart you wish to deploy and use the correct repository URL where the DevLake Helm chart is stored.We also export the Helm chart deployment URL, which can be used to access the services provided by DevLake, though you may need to adjust the URL depending on the specific services exposed by the Helm chart.
Once the program above is run, Pulumi will handle the provisioning of the resources, and you'll end up with a running instance of DevLake on your DigitalOcean Kubernetes cluster.
