Deploy the ublhub helm chart on Digital Ocean Kubernetes Service
TypeScriptDeploying a Helm chart to a Digital Ocean Kubernetes Service (DOKS) involves several steps:
- Set up a Digital Ocean Kubernetes cluster.
- Install the Helm CLI tool on your local machine.
- Configure Helm to work with your DOKS.
- Deploy the Helm chart to your cluster.
Below is a sample Pulumi program in TypeScript to accomplish the first step, which is to set up a Kubernetes cluster on Digital Ocean. The subsequent steps are typically done using the Helm CLI on your local machine, rather than through Pulumi.
import * as digitalocean from "@pulumi/digitalocean"; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // The region where the cluster is deployed version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default", size: "s-2vcpu-2gb", // The size of the Droplets (VMs) for the worker nodes nodeCount: 2, // The number of worker nodes }, }); // Export the Kubernetes kubeconfig file which you will use with `kubectl` and Helm. export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
After you've created your Kubernetes cluster using Pulumi, you'll need to:
- Install Helm on your local machine: You can follow the official instructions to install Helm.
- Configure Helm for DOKS: After cluster creation, download the generated kubeconfig file from Pulumi's stack output, which allows you to interact with your cluster using
kubectl
and Helm. - Add the Helm chart repository: Helm charts are typically hosted in repositories. Assuming
ublhub
is located in a known repository, add it usinghelm repo add
. - Deploy the Helm chart: Use
helm install
to deploy yourublhub
chart to the DOKS.
Here's a conceptual outline of the commands (This is not part of the Pulumi program and would be run in your shell):
# These steps would be performed manually in the command line # Initialize Helm by adding the chart's repository (assuming you know the repository URL). helm repo add ublhub-repo <repository-URL> # Install the `ublhub` chart into your DOKS. The `<release-name>` is a name you give to this particular deployment. helm install <release-name> ublhub-repo/ublhub # After installation, you can check the status of the deployment with: helm status <release-name>
Remember that the Pulumi program above only sets up the Kubernetes cluster in Digital Ocean. The actual deployment of the Helm chart is a separate step that involves interacting with the cluster using Helm on your local machine, which Pulumi does not manage.
Make sure to replace placeholder tokens with actual values, such as
<repository-URL>
and<release-name>
, when you run thehelm
commands.
