1. Deploy the zebrands helm chart on Digital Ocean Kubernetes Service


    To deploy the Zebrands Helm chart on the Digital Ocean Kubernetes Service using Pulumi, we will follow these steps:

    1. Set up the Digital Ocean Kubernetes cluster.
    2. Deploy the Helm chart onto the Kubernetes cluster.

    Step 1: Define a Digital Ocean Kubernetes Cluster

    We use the digitalocean.KubernetesCluster resource to create a Kubernetes cluster on Digital Ocean. This resource specifies the configurations like region, version, and node pool details.

    Node Pool details:

    • Size: The size of the droplets.
    • Node count: The initial number of nodes.

    Step 2: Deploy the Helm Chart

    Using the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider, we deploy the Zebrands Helm chart onto our Digital Ocean Kubernetes cluster.

    This resource requires that we have a Kubernetes provider configured with the context of the cluster we created. It also specifies the Helm chart by its name, which in this case is 'zebrands'. You may need to specify a chart version or additional configuration values, depending on the Helm chart you are using.

    Here's the complete Pulumi program to accomplish this:

    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('zebrands-cluster', { // Set the region for your cluster region: 'nyc3', // Specify the version of Kubernetes version: '1.21.5-do.0', // Configure the node pool nodePool: { size: 's-2vcpu-2gb', name: 'default', // Adjust the number of nodes as necessary nodeCount: 2, }, }); // Use the cluster's kubeconfig to create a Kubernetes Provider const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the Helm chart on the Digital Ocean Kubernetes cluster const zebrandsChart = new kubernetes.helm.v3.Chart('zebrands-chart', { chart: 'zebrands', // Name of the Helm chart // Use the version field if you need to pin to a specific chart version // version: "<version-number>", // Add any required custom values here values: { // Example: setting a custom value for the chart // key: "value", }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Export the public IP to access the Helm chart application if available // Sometimes Helm charts have a service of type LoadBalancer that // provides a public IP to access your application. If that's the case, // you can fetch the IP from the service object in the Helm chart like this: // // export const appPublicIP = zebrandsChart.getResourceProperty( // "v1/Service", // "<service-name>", // The name of the service with the LoadBalancer type // "status" // ).apply(status => status.loadBalancer.ingress[0].ip);

    To understand the entire process, let's explain what we did:

    1. We imported the necessary Pulumi providers for Digital Ocean and Kubernetes.
    2. We defined a Digital Ocean Kubernetes cluster with the desired configuration.
    3. We instantiated a Kubernetes Provider using the kubeconfig of the created cluster.
    4. We declared a Helm chart resource, specifying the chart details and values.
    5. Finally, we exported the kubeconfig, which you would use to interact with the cluster using kubectl.

    Be sure to replace any placeholder values, such as <version-number> or <service-name>, with actual values meant for your deployment. If additional configuration is required for the Zebrands chart, you should include such configurations in the values field of the Helm chart resource.

    This program will set up your Kubernetes cluster on Digital Ocean and deploy the Zebrands Helm chart when you run it using Pulumi's CLI. Make sure to have the Pulumi CLI installed and configured to use your Digital Ocean access token. Once your environment is set up correctly, you can run pulumi up to start the deployment process.
