1. Deploy the push-notifications helm chart on Digital Ocean Kubernetes Service


    To deploy a Helm chart on a DigitalOcean Kubernetes cluster, you'll need to go through several steps. Below I will guide you through creating a cluster on DigitalOcean, adding a Helm chart, and deploying it.

    Firstly, you need to set up a DigitalOcean Kubernetes cluster. For this, you'll use the digitalocean.KubernetesCluster resource. Then, once the cluster is set up, you'll deploy a Helm chart to this cluster using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider.


    • Make sure you have Pulumi CLI installed.
    • You have set up the DigitalOcean provider for Pulumi.
    • You have configured access to your DigitalOcean account via a token.
    • kubectl installed on your local machine, configured with the context to connect to your DigitalOcean cluster.

    Here's your Pulumi TypeScript program to deploy a DigitalOcean Kubernetes cluster and then deploy a Helm chart to it:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a DigitalOcean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // You can choose a region that's closer to you version: "latest", // Specify the version of Kubernetes you want to use nodePool: { name: "default", size: "s-1vcpu-2gb", // Choose the Droplet size that fits your needs nodeCount: 2, // Decide how many nodes you'd like in your node pool } }); // Export the kubeconfig file of the cluster. export const kubeconfig = cluster.kubeConfigs.apply(kubeConfig => kubeConfig[0].rawConfig); // Create a Kubernetes provider that uses the kubeconfig from the DigitalOcean cluster. const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Define the Helm chart for push-notifications. // Make sure you have the correct values like 'repo' and 'chart'. const pushNotificationsChart = new kubernetes.helm.v3.Chart("push-notifications-chart", { chart: "push-notifications", // Replace with the correct chart name // If your chart is in a specific Helm repository, configure the repo attribute. // repo: "https://charts.example.com/", // Uncomment this line and replace with the Helm chart's repository URL values: { // Place your values here or reference a values YAML file. // Example value: // service: { // type: "ClusterIP", // }, }, }, { provider: k8sProvider }); // Export the endpoint to access the push-notifications service export const endpoint = pushNotificationsChart.getResourceProperty("v1/Service", "push-notifications-service", "status").apply(status => status.loadBalancer.ingress[0]);


    1. We import the necessary packages from Pulumi's library that allows us to work with DigitalOcean and Kubernetes.

    2. A new DigitalOcean Kubernetes cluster is created using the digitalocean.KubernetesCluster class. We specify the region where the cluster will be deployed, the version of Kubernetes, and the details of the node pool.

    3. We export the kubeconfig which will be needed to interact with your Kubernetes cluster using kubectl.

    4. We then create a Kubernetes provider instance that utilizes this kubeconfig. This provider will facilitate the communication with your cluster.

    5. Following the setup of the provider, we define the Helm chart resource. We specify the chart's name and other optional properties like the repository URL and any values that you want to override in the default chart configuration. The values property is where you can provide custom configuration for your chart. Replace the placeholders accordingly based on your Helm chart's requirements.

    6. Finally, we export an endpoint that can be used to access the push-notifications service when it's up and running. Note that this assumes your Helm chart creates a Service resource named push-notifications-service which provides an external endpoint. If the chart creates resources with different names or if there are multiple services, you'll need to adjust the code.

    By running this program with Pulumi, your cluster will be provisioned, and the push-notifications Helm chart will be deployed on it. Remember to replace placeholders and configurations with the actual values regarding your chart and the desired DigitalOcean cluster configuration.
