1. Deploy the grafana-misc-dashboards helm chart on Digital Ocean Kubernetes Service


    To deploy the grafana-misc-dashboards Helm chart on the Digital Ocean Kubernetes service using Pulumi, you will need to follow these steps:

    1. Create a Digital Ocean Kubernetes Cluster: This resource is required to run the Kubernetes workloads. It stands up a Kubernetes cluster in Digital Ocean with the specified configuration.

    2. Deploy Helm Chart on Kubernetes Cluster: Once the Kubernetes cluster is running, you can deploy the grafana-misc-dashboards Helm chart onto the cluster. You'll use the Kubernetes Helm Chart resource provided by Pulumi for this purpose.

    Here is a Pulumi TypeScript program that achieves these goals:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // You can change the region as per your requirement version: "latest", // This will use the latest available version of Kubernetes nodePool: { name: "default", size: "s-1vcpu-2gb", // This is the size for each node in the node pool nodeCount: 2, // Number of nodes in the node pool }, }); // Kubeconfig to access the created Kubernetes cluster const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Using the kubeconfig to install Helm chart const k8sProvider = new kubernetes.Provider("do-k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the Grafana Helm chart const grafanaChart = new kubernetes.helm.v3.Chart("grafana-misc-dashboards", { chart: "grafana", version: "6.1.9", // Specify the version of the Helm chart fetchOpts: { repo: "https://grafana.github.io/helm-charts", // Repository where the Helm chart is located }, values: { // Specify any values needed for the grafana-misc-dashboards chart. // This would be the equivalent of what you would put into a values.yaml file // or pass via '--set' flags to 'helm install'. }, }, { provider: k8sProvider }); // Export the Digital Ocean Kubernetes cluster endpoint export const kubeClusterEndpoint = cluster.endpoint; // Run `$ pulumi up` to start deployment and see the logs for running this application // After deployment, you can use the exported KubeClusterEndpoint to interact with your // Grafana instance using `kubectl`.

    In this program:

    • Digital Ocean Kubernetes Cluster: We create a Kubernetes cluster using the digitalocean.KubernetesCluster component. The region, version, and nodePool properties configure the location, Kubernetes version, and the type and number of nodes, respectively.

    • KubeConfig: The kubeconfig is retrieved from the created Kubernetes cluster, which will allow you to interact with the cluster using kubectl and other tools.

    • Kubernetes Provider: We then instantiate a Pulumi Kubernetes Provider, passing in the kubeconfig. This sets up the Pulumi context to use our new DigitalOcean Kubernetes cluster.

    • Grafana Helm Chart: The Grafa Chart resource specifies the Helm chart we want to deploy ('grafana') from the specified repository. You would typically customize the values property with the specific settings you need for your Grafana deployment. Here, we use the default values.

    • Exported Endpoint: After deployment, the Kubernetes cluster's endpoint is exported, which you can use to interact with your cluster using kubectl.

    Remember to replace "6.1.9" with the version of the Helm chart you wish to deploy and set any values specific to the grafana-misc-dashboards chart you might need.

    To deploy this Pulumi program:

    1. Install Pulumi: Follow the instructions at Pulumi's installation guide.

    2. Configure Digital Ocean: Configure Pulumi to access your Digital Ocean account by setting the DIGITALOCEAN_TOKEN environment variable with your Digital Ocean access token, which you can generate from the Digital Ocean control panel.

    3. Run Pulumi Program:

      • Navigate to the directory containing your Pulumi program.
      • Install dependencies: npm install
      • Run pulumi up to preview and deploy the changes.

    This will set up the infrastructure and the Grafana dashboards on your Digital Ocean Kubernetes cluster.
