Deploy the upyun-exporter helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would need to have access to a Rancher Kubernetes cluster and the appropriate permissions to deploy applications to it. I'll guide you through the steps on how to accomplish this using Pulumi and TypeScript.

Before you begin, ensure:

You have Pulumi installed and configured with the appropriate cloud provider credentials.
You have access to a Rancher Kubernetes cluster and have the kubeconfig file for connecting to your Kubernetes cluster.
You have the necessary permissions to deploy Helm charts in the cluster.

First, we will use the Pulumi Kubernetes provider to deploy the Helm chart to the Kubernetes cluster managed by Rancher. The upyun-exporter Helm chart you mentioned may be a third-party chart or a custom one you have created. If it's a Helm chart available in a public Helm repository, you would need to add that repository to the repositories input in the helm.v3.Chart resource. If it's a private chart or not available in a public repository, you will need to ensure that its repository is accessible from your Kubernetes cluster and that any necessary authentication has been handled.

Here is a TypeScript program that demonstrates how to deploy a hypothetical upyun-exporter Helm chart:

import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Create a provider resource that specifies the kubeconfig for Rancher.
const rancherK8sProvider = new k8s.Provider("rancher-k8s-provider", {
    kubeconfig: '<Your Rancher Cluster Kubeconfig>', // Replace with your actual kubeconfig
});

// Deploy the upyun-exporter Helm chart using the Pulumi Kubernetes provider.
const upyunExporterChart = new k8s.helm.v3.Chart("upyun-exporter", {
    chart: "upyun-exporter",
    version: "1.0.0", // Replace with the specific chart version you want to deploy
    fetchOpts:{
        repo: "https://charts.yourorg.com/", // Replace with the URL to the chart repository
    },
}, { provider: rancherK8sProvider });

// Export the resources created.
export const chartName = upyunExporterChart.metadata.name;

You'll need to replace placeholders like <Your Rancher Cluster Kubeconfig> with the actual values that you'll be using.

In the above program:

We import the Pulumi SDK and Kubernetes package.
We create a Kubernetes provider that uses the kubeconfig for the Rancher-managed cluster. You'll replace the placeholder with your kubeconfig content.
We use the k8s.helm.v3.Chart resource to deploy the upyun-exporter Helm chart. Replace chart, version, and repo with the correct values for the upyun-exporter chart you wish to deploy.
As an output, we're exporting the name of the chart that gets deployed, though you could export other details such as the active endpoint once the chart is deployed.

Note: This assumes that the upyun-exporter chart is stored in a Helm repository. If this is not the case, or if you have a local chart, you may need to adjust the fetch options accordingly.

Once you've replaced the placeholders with the actual values and you have the Pulumi program ready, you can run pulumi up to deploy the chart to your Rancher-managed Kubernetes cluster.

Remember that the actual chart may have certain configurations and values that need to be supplied. This can be done through the values property for the Chart resource where you can provide a mapping of configuration values that the chart expects.
