Deploy the grafana-dashboards-rancher helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the Grafana dashboards using the Rancher Helm chart on an Azure Managed OpenShift Service, you'll need to follow these steps:

1. Create an OpenShift Managed Cluster in Azure.
2. Install the Helm CLI tool to manage Helm chart deployments.
3. Deploy the `grafana-dashboards-rancher` Helm chart on your OpenShift Cluster.

Below is a TypeScript program for Pulumi that automates this process:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azureNative from "@pulumi/azure-native";
import * as k8s from "@pulumi/kubernetes";

// Create an Azure Resource Group
const resourceGroup = new azureNative.resources.ResourceGroup("resourceGroup", {
   location: "EastUS", // Adjust the location to your preferred Azure region
});

// Create an Azure OpenShift Managed Cluster
const cluster = new azureNative.containerservice.OpenShiftManagedCluster("openshiftCluster", {
   resourceName: "openshiftCluster",
   resourceGroupName: resourceGroup.name,
   location: resourceGroup.location,
   openShiftVersion: "4.3", // Specify the version of OpenShift
   // Specify the other properties as needed, like network, master, and worker profiles
   masterPoolProfile: {
       count: 3,
       vmSize: "Standard_D4s_v3",
   },
   agentPoolProfiles: [{
       name: "agentpool",
       count: 3,
       vmSize: "Standard_D4s_v3",
       role: "compute", // this defines the role for the agent pool
   }],
}, {dependsOn: resourceGroup});

// Get cluster credentials to use with the Helm provider
const creds = pulumi.all([resourceGroup.name, cluster.name]).apply(([resourceGroupName, clusterResourceName]) => 
   azureNative.containerservice.listOpenShiftManagedClusterAdminCredentials({
       resourceGroupName,
       resourceName: clusterResourceName,
   })
);

// // Now, we will define a Pulumi Kubernetes provider to interact with the OpenShift cluster.
const k8sProvider = new k8s.Provider("openshiftK8s", {
   kubeconfig: creds.kubeConfigRaw,
});

// Finally, deploy the Grafana dashboards using the Rancher Helm chart
const grafanaDashboardChart = new k8s.helm.v3.Chart("grafanaDashboards", {
   chart: "grafana-dashboards-rancher", // This should be the name of the chart in the Helm repository
   fetchOpts:{
      repo: "https://helm.rancher.io/", // This is the Rancher Helm chart repository URL
   },
   // If there are specific configurations you need to override, specify it in `values`
   values: {
       // Specify any custom values for your Grafana dashboards here
       // This might include aspects like service types, annotations, resources, etc.
   },
}, {provider: k8sProvider});

// Export the endpoint of the Grafana dashboard service
export const grafanaDashboardUrl = grafanaDashboardChart.getResourceProperty("v1/Service", "grafana-dashboards-rancher", "status")
   .apply(status => status.loadBalancer.ingress[0].ip);
```

This Pulumi program does the following:

- **Define a Resource Group:** Create a resource group in Azure to contain all related resources for your OpenShift cluster.
- **Provision the OpenShift Managed Cluster:** Set up Azure Red Hat OpenShift, defining the node sizes and counts.
- **Retrieve Credentials:** Fetch the necessary kubeconfig to interact with your OpenShift cluster upon its creation.
- **Set up a Kubernetes Provider with OpenShift Credentials:** Configure Pulumi's Kubernetes provider with the credentials to manage the cluster.
- **Deploy the Grafana Dashboard Helm Chart:** Use the Kubernetes provider to deploy the `grafana-dashboards-rancher` Helm chart from the Rancher chart repository.

Make sure to replace any placeholders or configurations within the code with values specific to your environment, such as specifying the right OpenShift version, region, node sizes, and chart values. After deploying with Pulumi, you'll get the endpoint of the Grafana dashboard service as an exported URL.

To run this Pulumi program, you would need to have Pulumi installed and configured:

1. Install the Pulumi CLI: [Pulumi Installation Guide](https://www.pulumi.com/docs/get-started/install/).
2. Log in to Pulumi CLI: `pulumi login`.
3. Set up your Azure Credentials: [Pulumi with Azure](https://www.pulumi.com/docs/intro/cloud-providers/azure/setup/).
4. Run `pulumi up` to create and apply the deployment.

This is a basic guide to get you started, and you might need to adjust parameters such as the size and number of master and agent nodes, or OpenShift version based on your requirements and the Helm chart values to fit the configuration that you need for the Grafana dashboards.
