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


    To deploy a Helm chart on the Digital Ocean Kubernetes Service using Pulumi, we'll need to use two main resources:

    1. digitalocean.KubernetesCluster: This resource is used to create a managed Kubernetes cluster on Digital Ocean. It allows us to define the number of nodes, the node size, and other configurations related to networking and maintenance.

    2. kubernetes.helm.v3.Chart: This resource is used to deploy a Helm chart into a Kubernetes cluster. It packages all the resources needed for a typical application into a single deployable unit.

    In the following program, we'll define a Digital Ocean Kubernetes cluster and deploy the "uui" Helm chart onto it. We'll assume that "uui" is a Helm chart available in a public or private chart repository.

    Make sure to replace the repo and chart properties with the appropriate values for your "uui" Helm chart. If the "uui" chart requires specific configuration values, you can provide them as a dictionary to the values property.

    Here's how you can do it in Pulumi with TypeScript:

    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: "nyc3", // Choose the region where you want to deploy your cluster version: "1.21.5-do.0", // Specify the version of Kubernetes nodePool: { name: "default", size: "s-2vcpu-2gb", // Choose the size of the nodes based on your requirements nodeCount: 2, // The number of nodes in the Kubernetes cluster }, }); // Create a Kubernetes provider instance that uses the kubeconfig from the newly-created cluster const k8sProvider = new kubernetes.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the "uui" Helm chart into the Kubernetes cluster const uuiChart = new kubernetes.helm.v3.Chart("uui-chart", { chart: "uui", version: "1.0.0", // Use the version of the chart you want to deploy namespace: "default", // The Kubernetes namespace to deploy the chart. You may create a new namespace if required. // `repo` property is optional and it is used only if the chart is in a remote repository fetchOpts: { repo: "http://charts.example.com/", // Replace with the actual repository URL }, values: { // Add any values here to configure the chart installation key1: "value1", key2: "value2", // ... }, }, {provider: k8sProvider}); // Specify the provider created from the cluster's kubeconfig // Export the cluster's kubeconfig and the endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const endpoint = cluster.endpoint;

    In this program:

    • We set up a new Digital Ocean Kubernetes cluster (digitalocean.KubernetesCluster) in New York City 3 region with 2 nodes that have 2 vCPUs and 2GB of RAM each. You can modify these values to match your specific requirements.
    • We instantiate the Kubernetes provider (kubernetes.Provider) using the kubeconfig from the newly created cluster.
    • We deploy the "uui" chart (kubernetes.helm.v3.Chart) into the default namespace of our cluster. We specify that the chart comes from a Helm repository at http://charts.example.com/, and we pass some placeholder values.
    • We export the kubeconfig and endpoint for convenience, allowing you to interact with the cluster using kubectl or other Kubernetes tools.

    Remember to change the chart details and values to match the specifics of the "uui" chart you are deploying. If the chart is stored locally instead of a repository, you'll need to provide a path property rather than repo and fetchOpts.
