Deploy the fastly-exporter helm chart on Kubernetes
TypeScriptTo deploy the
fastly-exporter
Helm chart on a Kubernetes cluster using Pulumi, you'll need to follow these steps:-
Have access to a Kubernetes cluster: Before you begin, make sure you have a Kubernetes cluster running and that you have
kubectl
installed and configured to interact with that cluster. -
Include required Pulumi packages: Ensure that the
@pulumi/kubernetes
package is included in your project's dependencies, as this package allows you to work with Kubernetes resources within Pulumi. -
Utilize the Helm Chart resource: You can use the
kubernetes.helm.v3.Chart
resource from the@pulumi/kubernetes
package to deploy Helm charts. This resource represents a Helm chart in a Pulumi program.
Here’s a Pulumi program written in TypeScript that shows how to deploy a Helm chart to your Kubernetes cluster.
import * as k8s from "@pulumi/kubernetes"; const fastlyExporterChart = new k8s.helm.v3.Chart("fastly-exporter", { chart: "fastly-exporter", // Specify the Helm chart repository here, if it is not part of the stable repository. // repo: "https://my-helm-charts.example.com/", version: "0.1.0", // Specify the exact chart version you want to deploy. // You may also pass additional values to configure the Helm chart as needed. values: { // Provide configuration values for the fastly-exporter chart here. // Example: // serviceMonitor: { // enabled: true, // }, }, // Namespace where the Helm chart will be installed namespace: "default", // Change this if you wish to install the chart in a different namespace. }); // Optional: Export the public IP to access fastly-exporter if it creates an external endpoint. export const fastlyExporterIP = fastlyExporterChart.getResourceProperty("v1/Service", "fastly-exporter", "status").apply(status => status.loadBalancer.ingress[0].ip);
This program defines a new
fastly-exporter
Helm chart and attempts to deploy it to a Kubernetes cluster. It assumes that you have thefastly-exporter
chart available in your Helm chart repository. If your chart is hosted in a private or custom Helm chart repository, you will have to include therepo
field with the URL of the repository.Key points to note:
- The
chart
field specifies the name of the Helm chart. Here, it is"fastly-exporter"
. - The
version
field allows you to specify the version of the Helm chart you want to use. Replace"0.1.0"
with the actual version of thefastly-exporter
chart you want to deploy. - The
values
field allows you to specify configuration options for the chart. This is equivalent to customization you might perform using command-line arguments with Helm or avalues.yaml
file.
Finally, if the Helm chart exposes an external endpoint through a Kubernetes
Service
of typeLoadBalancer
, I included an optional export of the resulting IP address, namedfastlyExporterIP
, which allows you to determine the IP address assigned by the load balancer.Before you run the Pulumi program, make sure to install the required Pulumi command-line tools and TypeScript dependencies using
npm
oryarn
.To deploy this code:
- Ensure you have an active directory with a Pulumi project set up.
- Save this code in an
index.ts
file (the main file in a TypeScript Pulumi project). - Ensure you have the Kubernetes provider configured either through a kubeconfig file or Pulumi configuration.
- Use the Pulumi CLI to run
pulumi up
, which will prompt you for confirmation before deploying the Helm chart to your cluster.
Remember to replace placeholder values with actuals as per your requirements.
