Deploy the kube-metrics-adapter helm chart on Rancher
TypeScriptTo deploy the
kube-metrics-adapter
Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we'll follow these steps:- Set up the necessary Rancher 2.x provider and authenticate with your Rancher instance.
- Deploy the Helm chart to your Kubernetes cluster using the Pulumi resource
Chart
from the@pulumi/kubernetes
package.
Here's a step-by-step guide, along with the corresponding TypeScript program:
Step 1: Set Up the Rancher 2.x Provider
Install the Pulumi Rancher 2 package using npm:
npm install @pulumi/rancher2
Now authenticate with Rancher. Pulumi will respect the
RANCHER_ACCESS_KEY
,RANCHER_SECRET_KEY
, andRANCHER_SERVER_URL
environment variables to facilitate this. Ensure they are set in your environment before running your Pulumi program.Step 2: Install the Helm Chart
Next, we will use the
helm.Chart
resource from the@pulumi/kubernetes
package to deploy thekube-metrics-adapter
Helm chart. This assumes that you have already set up your Pulumi program to communicate with a Kubernetes cluster managed by Rancher.If you haven't done so, install the Pulumi Kubernetes package using npm:
npm install @pulumi/kubernetes
You will also need to configure your Pulumi Kubernetes provider to communicate with the Kubernetes cluster. This usually involves setting up a
kubeconfig
file that Pulumi can use.Here's a simple program that demonstrates how to deploy the
kube-metrics-adapter
Helm chart:import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Initialize a Kubernetes provider using Rancher's kubeconfig obtained via the Rancher API or other means. const k8sProvider = new k8s.Provider("rancher-k8s", { kubeconfig: "<YOUR_KUBECONFIG_CONTENT>", }); // Deploy kube-metrics-adapter using the Helm Chart const kubeMetricsAdapterChart = new k8s.helm.v3.Chart("kube-metrics-adapter", { fetchOpts:{ repo: "https://github.com/zalando-incubator/kube-metrics-adapter", }, chart: "kube-metrics-adapter", // Specify the version of the chart you wish to deploy version: "1.1.0", // Values to pass to the helm chart, this would be where you can configure the chart. values: { // Replica count, image, resources, etc. would be configured here as needed. }, }, { provider: k8sProvider });
The
kubeMetricsAdapterChart
instance creates a Helm release on your Rancher Kubernetes cluster. To specify the version of the Helm chart, you can replace1.1.0
with the desired chart version.Remember to fill in
<YOUR_KUBECONFIG_CONTENT>
with the actual contents of your kubeconfig file or a path to the file. This tells the Kubernetes provider how to communicate with your Rancher-managed cluster.When you run this Pulumi program using the
pulumi up
command, it interacts with Rancher using the Rancher provider and deploys thekube-metrics-adapter
Helm chart to your Kubernetes cluster.Make sure you have the Helm repository with the
kube-metrics-adapter
Helm chart. You may need to adjust therepo
URL to the correct repository where the chart is hosted.Additional Information
