Deploy the stakater-helm-push helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on a Rancher-managed Kubernetes cluster, you would typically follow these steps:

1. Set up a Rancher Kubernetes cluster and access it.
2. Install or ensure that Helm is available in your local environment or where you plan to run the deployment.
3. Add the Helm chart repository that contains the `stakater-helm-push` chart.
4. Use Helm to deploy the chart to your Rancher cluster.

Using Pulumi, we can automate the setup of the Kubernetes cluster as well as the deployment of the Helm chart. However, it looks like the `stakater-helm-push` chart is not directly related to the resources available in the listed Pulumi Registry Results. Generally, to deploy Helm charts with Pulumi, you would use the `pulumi/kubernetes` library.

Below is a program that demonstrates how to use Pulumi to deploy a Helm chart to a Kubernetes cluster. In the absence of a specific `stakater-helm-push` chart in the listings and assuming your Rancher cluster is already set up, the program will focus on deploying a generic Helm chart which you can replace with `stakater-helm-push`.

Please note that actual deployment might require specific values that should be passed to the Helm chart for it to work correctly, including but not limited to configuration values like service endpoints, authentication credentials, and resource constraints.

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

// Replace 'my-cluster' with the name of your Rancher-managed Kubernetes cluster.
// Ensure you have configured your Pulumi to use the desired Rancher Kubernetes context
// for this, which is established by pointing to a valid KUBECONFIG environment variable or file.
const clusterName = "my-cluster";

// Define a new Kubernetes provider instance that uses the context for your Rancher cluster.
const rancherK8sProvider = new k8s.Provider(clusterName, {
  kubeconfig: process.env.KUBECONFIG, // Ensure this environment variable is set correctly
});

// Add the Helm chart repository where the 'stakater-helm-push' chart is located.
// You need to provide the URL to the Helm repository that contains your desired chart.
const helmRepo = "https://charts.repohost.com/";
const chartName = "stakater-helm-push"; // The name of the chart in the Helm repository
const chartVersion = "1.0.0"; // Replace with the specific version you want to deploy

// Deploy 'stakater-helm-push' Helm chart using Pulumi.
const helmChart = new k8s.helm.v3.Chart("stakater-helm-push", {
  // Assuming the Helm chart is named 'stakater-helm-push' and it is hosted in the added repository.
  repo: "my-chart-repo-name", // Replace with the actual repo name
  chart: chartName,
  version: chartVersion,
  // Namespace where the chart will be installed. Create one if needed or use an existing one.
  namespace: "default",
  // Specify any custom values for the Helm chart. They depend on the chart's configuration options.
  values: {
    // Custom values for the chart
    // For instance:
    // image: { repository: "stakater/stakater-helm-push", tag: "latest" },
    // service: { type: "ClusterIP", port: 80 },
    // This should be customized based on the chart's requirements.
  },
}, { provider: rancherK8sProvider });

export const helmChartName = helmChart.metadata.apply(m => m.name);
```

Before you run the Pulumi program, ensure the `KUBECONFIG` environment variable is correctly pointing to the kubeconfig file that grants access to your Rancher Kubernetes cluster.

This Pulumi program uses the `@pulumi/kubernetes` package to interact with Kubernetes resources. A `k8s.Provider` instance is created to interact with the Rancher cluster using the given kubeconfig data. A Helm chart is instantiated using `k8s.helm.v3.Chart` which will install the specified Helm chart from the given repository to your Kubernetes cluster.

You will need to replace `my-chart-repo-name` with the actual repository name where your `stakater-helm-push` chart is found. The `values` object should be filled with the necessary values that customize the Helm chart you are deploying. Additionally, you should confirm the version of the chart to match what you wish to deploy.

Remember that the Pulumi code above should be executed in an environment where Pulumi is installed and configured. Pulumi programs are executed using the `pulumi up` command in the command line, which will prompt you for confirmation before performing any actions on the cloud resources.
