Deploy the kube-plex helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the kube-plex Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you'll need to follow these steps:

1. Ensure you have access to a Rancher-managed Kubernetes cluster and your `kubeconfig` file is set up correctly to interact with it.
2. Install Pulumi and set up your Pulumi environment.
3. Create a new Pulumi project or use an existing one where you want to deploy the kube-plex chart.
4. Write a Pulumi program in TypeScript to deploy the helm chart.

Here's what the Pulumi program would look like in TypeScript:

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

// Initialize a Kubernetes provider with the default kubeconfig credentials
const rancherK8sProvider = new kubernetes.Provider("rancherK8sProvider", {
    kubeconfig: pulumi.output(pulumi.getStackReference("reference-to-rancher-stack").getOutput("kubeconfig")),
});

// Deploy the kube-plex Helm chart into the Rancher-managed cluster
const kubePlexChart = new kubernetes.helm.v3.Chart("kube-plex", {
    chart: "kube-plex",
    version: "version-number", // Specify the version number of kube-plex chart if necessary
    namespace: "target-namespace", // Specify the namespace where the chart should be deployed
    // Values to override within the Helm Chart
    values: {
        // Specify any values that are necessary for your kube-plex deployment
    },
}, { provider: rancherK8sProvider });

// Export the name of the chart
export const chartName = kubePlexChart.metadata.name;
```

Let's break this down:
- We import the required Pulumi modules.
- We set up a new `Provider` instance for Kubernetes. This provider uses the kubeconfig from a Rancher stack reference, which you need to have set up prior to running this program. Make sure to replace `"reference-to-rancher-stack"` with the actual name of your Rancher stack reference.
- We then use the imported `helm` module to deploy the `kube-plex` chart by creating a new `Chart` resource. You'd need to specify the chart name (`kube-plex`), chart version (if known), and namespace for your deployment. Also set the `provider` to the provider instance we just created.
- The `values` property is an object that should include any setting you want to override in the Helm chart. You'll need to consult the `kube-plex` Helm chart documentation or values.yaml file to find out what values you can override.

Don't forget to replace `"version-number"`, `"target-namespace"`, and the values object with the actual details matching your desired kube-plex configuration.

To run this Pulumi program:
- Navigate to your Pulumi project directory.
- Run `pulumi up` to preview and deploy your stack.

Please ensure Pulumi, kubectl, and access to your Rancher cluster are all correctly configured before running your Pulumi program.
