1. Deploy the uptime-monitor helm chart on Digital Ocean Kubernetes Service


    To deploy the uptime-monitor Helm chart on Digital Ocean Kubernetes Service using Pulumi, you'll first need to set up a Kubernetes cluster on Digital Ocean. Then you can install the chart onto your cluster.

    I'll guide you through the following steps:

    1. Set up the Digital Ocean Kubernetes cluster.
    2. Deploy the uptime-monitor Helm chart to the cluster.

    Step 1: Create a Kubernetes Cluster in Digital Ocean

    To create a Kubernetes cluster in Digital Ocean, you can use the digitalocean.KubernetesCluster resource. You need to specify the region, version, and node pool configuration for your cluster.

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a Digital Ocean Kubernetes Cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", // Choose the region that is close to you or your users version: "1.21.5-do.0", // Specify the version of Kubernetes nodePool: { name: "default-pool", size: "s-2vcpu-2gb", // Choose the size that fits your needs nodeCount: 3, // Number of nodes in the node pool }, }); // Export the kubeconfig and the cluster ID export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterId = cluster.id;

    Step 2: Deploy the Helm Chart to the Kubernetes Cluster

    Since we don't have a specific uptime-monitor Helm chart in the Pulumi registry results, we will use the generic kubernetes.helm.v3.Chart resource which allows you to deploy a Helm chart from a repository. You will need to specify the name of the chart and the repository URL it can be found at.

    Please, make sure you have the correct Helm chart name and repository URL.

    // Ensure to configure the Pulumi Kubernetes provider with the kubeconfig from the created cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the uptime-monitor Helm chart const uptimeMonitorChart = new k8s.helm.v3.Chart("uptime-monitor", { chart: "uptime-monitor", // The name of the chart version: "1.0.0", // The version of the chart, adjust as necessary fetchOpts: { repo: "http://helm-repo-url/", // Replace with the repository URL }, }, { provider: k8sProvider }); // Export the uptime-monitor service endpoint export const serviceEndpoint = uptimeMonitorChart.getResourceProperty("v1/Service", "uptime-monitor", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Here's what happens in the code above:

    • We set up a new Kubernetes cluster with a specific configuration on Digital Ocean using the digitalocean.KubernetesCluster resource.
    • We create a new instance of k8s.Provider configured with the kubeconfig from our deployed Digital Ocean Kubernetes cluster.
    • We deploy the uptime-monitor Helm chart to our Kubernetes cluster by using the generic k8s.helm.v3.Chart resource.

    In this code, http://helm-repo-url/ is a placeholder and should be replaced with the actual Helm chart repository URL where uptime-monitor is hosted. The version property should also be set to the version of the uptime-monitor chart that you want to deploy.

    Before Running the Code

    Before you run this code ensure the following prerequisites are met:

    1. Install Pulumi CLI.
    2. Set up Pulumi to use Digital Ocean.
    3. Replace http://helm-repo-url/ with the actual Helm chart repository URL.
    4. Adjust the Helm chart version property if needed.
    5. Choose the appropriate Digital Ocean region and node size for your Kubernetes cluster.

    After you have the Pulumi program ready, you can run it using the following commands:

    pulumi up

    This command will start the deployment process, and you will be prompted to review the changes before they are applied. Once you confirm, Pulumi will execute the changes and deploy your Kubernetes cluster and the Helm chart.

    To clean up the resources, you can run:

    pulumi destroy

    This will remove all resources that have been deployed, including your Digital Ocean Kubernetes cluster and the uptime-monitor Helm chart.
