Deploy the elasticsearch-umbrella helm chart on Linode Kubernetes Engine
TypeScriptTo deploy the
elasticsearch-umbrella
Helm chart on the Linode Kubernetes Engine (LKE) using Pulumi, you'll need to use the Pulumi Kubernetes provider. This provider allows you to interact with Kubernetes resources, including deploying Helm charts. Before proceeding, make sure you've already set up your Linode account, created a cluster on LKE, and have yourkubeconfig
ready for Pulumi to interact with your Kubernetes cluster.Below is a step-by-step TypeScript program that deploys the
elasticsearch-umbrella
Helm chart. The program assumes you have already configured Pulumi for use with your Kubernetes cluster by setting up the appropriate kubeconfig.Here are the steps we'll follow in the code:
- Import necessary packages.
- Create a new Helm chart resource, referencing the
elasticsearch-umbrella
chart from its repository. - Provide necessary chart values.
- Deploy the chart to your LKE cluster.
Here's the program:
import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a Helm Chart resource for the elasticsearch-umbrella Helm chart. // You will need to replace `REPO_URL` with the actual repository URL of the elasticsearch-umbrella Helm chart. // The `version` is set to the specific version of the Helm chart you want to deploy. // The `values` section is where you would include any specific configuration values for your chart deployment. const esUmbrellaChart = new k8s.helm.v3.Chart("elasticsearch-umbrella", { chart: "elasticsearch-umbrella", version: "CHART_VERSION", // Specify the version of the chart to deploy fetchOpts: { repo: "REPO_URL", // Replace with the Helm chart's repository URL }, // Include additional configuration as needed: values: { // Customize the chart values here }, }); // Export any relevant resources or URLs export const chartName = esUmbrellaChart.metadata.name;
In the code above:
- Replace
REPO_URL
with the actual Helm repository URL where theelasticsearch-umbrella
chart is located. Typically this could be something likehttps://helm.elastic.co
. - Replace
CHART_VERSION
with the specific chart version number you wish to deploy. This ensures you can consistently redeploy the same version. - Under the
values
section, you can provide a set of configurations that match the configurable parameters of theelasticsearch-umbrella
Helm chart. For instance, you may want to specify the number of nodes, memory allocation, and such. You would need to refer to the chart's documentation to know what values are configurable.
Please note that this example assumes the
elasticsearch-umbrella
is the chart's name in the repository and is not meant to be taken literally unless there is a chart by this name in the Helm repository you are using.To run this Pulumi program:
- Install Pulumi and set up the Pulumi CLI with the
kubeconfig
for your LKE cluster. - Create a new directory for your Pulumi project and navigate to it in your terminal.
- Run
pulumi new typescript
to create a new Pulumi TypeScript project. - Replace the contents of
index.ts
with the code provided above. - Run
npm install
oryarn install
to make sure all dependencies are installed. - Execute
pulumi up
to preview and deploy the resources.
This will start the deployment process of your Elasticsearch Helm chart onto your LKE cluster. Once executed, you can watch the progress of the deployment in your terminal or through the Linode Cloud Manager if you have set it up to monitor your cluster's state. If the Helm chart requires specific configurations for Linode, make sure to incorporate those into the
values
object in the code.
