Deploy the grafana-stakewise-dashboards helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the `grafana-stakewise-dashboards` Helm chart on Rancher using Pulumi, you need to perform a few steps. First, you need to set up the Pulumi Rancher 2 provider. Then you'll have to instantiate a Rancher cluster, and finally, deploy the Helm chart onto the cluster.

Here is a detailed guide on how to achieve this:

1. **Setting up Pulumi with Rancher**: Pulumi provides a Rancher 2 provider that allows you to interact with Rancher. Make sure you have permissions to access Rancher and the credentials needed for authentication.

2. **Cluster Creation**: Before deploying the Helm chart, you need to have a Kubernetes cluster managed by Rancher. You can use an existing cluster or create a new one.

3. **Helm Chart Deployment**: Once you have a cluster, you can use Pulumi to deploy Helm charts to it. You'll define the `grafana-stakewise-dashboards` chart's deployment specifications and leave Pulumi to handle the deployment process.

Let's start composing our Pulumi program. This program is going to illustrate these steps in TypeScript. Be sure the Pulumi CLI is installed and that you're authenticated with your cloud provider before running this code.

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as rancher2 from '@pulumi/rancher2';
import * as k8s from '@pulumi/kubernetes';

// Step 1: Set up Pulumi to use the Rancher 2 provider.
// Ensure you have set up Rancher 2 provider credentials
// through Pulumi configuration or environment variables.

// Step 2: Use an existing Rancher2 Kubernetes cluster or create a new Rancher2 Kubernetes cluster.
const cluster = new rancher2.Cluster("my-cluster", {
    // You will need to fill in your cluster's configuration details here
    // or use an existing cluster's information to manage the desired resources.
});

// Step 3: Deploy the grafana-stakewise-dashboards Helm chart on the Rancher-managed cluster.
const grafanaStakewiseDashboardsChart = new k8s.helm.v3.Chart("grafana-stakewise-dashboards", {
    // Specify the Helm chart repository where the grafana-stakewise-dashboards chart is located
    chart: "grafana-stakewise-dashboards",
    version: "1.0.0", // Use the chart's version that you wish to deploy
    fetchOpts: {
        repo: "http://helm-repository-url/", // Replace with the actual Helm repo URL
    },
    // Define values for the helm chart in values.yaml format or inline YAML.
    values: {
        // Provide configuration that might be specific to the grafana-stakewise-dashboards chart here
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig }) });

// Export the chart's name as a stack output for easy access.
export const chartName = grafanaStakewiseDashboardsChart.metadata.name;
```

In this program, we are:

- Importing the necessary modules for Pulumi, including the Rancher2 and Kubernetes modules.
- Creating a new Rancher2 cluster, although we leave the configuration details for the user to fill in, as they will vary widely depending on the specific setup and requirements of the user's Rancher instance and cloud provider. Alternatively, the user may provide the name of an existing cluster.
- Deploying the `grafana-stakewise-dashboards` Helm chart onto the Rancher cluster. To do this, we define a new Helm chart resource specifying the chart details such as the repository and version. We also define the `values` field to pass in any required values to the Helm chart.
- The Helm chart resource relies upon a Kubernetes provider associated with the Rancher2 cluster we're targeting, which is instantiated with the `kubeconfig` derived from our defined or existing cluster.
- Exporting the name of the Helm chart as a stack output for reference.

Before running `pulumi up`, make sure to replace the placeholder values with the actual details of your Rancher setup and the Helm repository containing the `grafana-stakewise-dashboards` chart.

After you set up and run this Pulumi program, it will automate the deployment of the Grafana dashboard Helm chart onto your Rancher-managed Kubernetes cluster.

Remember that the specifics of your Rancher configuration and Helm chart details should be adjusted based on your setup. The versions, chart names, and all other resource identifiers should match what's available in your environment and the Helm Chart repository.
