1. Deploy the provider-openstack helm chart on Digital Ocean Kubernetes Service


    To deploy the provider-openstack Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you will need to follow the given steps:

    1. Set up a Digital Ocean Kubernetes Cluster: First, you'll create a Kubernetes cluster on Digital Ocean. Pulumi's Digital Ocean provider lets you create a cluster declaratively.

    2. Deploy the Helm Chart: After you have a Kubernetes cluster, you will use Pulumi's Kubernetes provider to deploy the Helm chart for provider-openstack.

    Here is a step-by-step guide with a program written in TypeScript which accomplishes this:

    Step 1: Installing Pulumi and Setting Up the Environment

    Before running the code, make sure to install Pulumi CLI and configure it with Digital Ocean as your cloud provider. This involves setting up the Digital Ocean access token. Follow the instructions on Pulumi's DigitalOcean setup page.

    Step 2: Writing the Pulumi Program

    First, install the necessary dependencies using npm or yarn:

    npm install @pulumi/digitalocean @pulumi/kubernetes


    yarn add @pulumi/digitalocean @pulumi/kubernetes

    Then write the following TypeScript code into a file named index.ts which you will run with Pulumi later.

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a Digital Ocean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "latest", nodePool: { name: "default", size: "s-1vcpu-2gb", nodeCount: 2, }, }); // Step 2: Using the cluster credentials to configure the Kubernetes provider const k8sProvider = new k8s.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploying the provider-openstack Helm chart const chart = new k8s.helm.v3.Chart( "openstack-provider", { chart: "provider-openstack", // Make sure to replace the `repo` value with the correct Helm chart repo URL fetchOpts: { repo: "https://charts.example.com/" }, }, { provider: k8sProvider } ); // Export the K8s cluster name and Kubeconfig export const clusterName = cluster.name; export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    This Pulumi program performs the following actions:

    • It creates a new Digital Ocean Kubernetes cluster in the nyc3 region with the latest Kubernetes version available on Digital Ocean. The node pool is set to have two nodes of the s-1vcpu-2gb size. (See DigitalOcean KubernetesCluster)

    • It initializes a Pulumi Kubernetes provider with the kubeconfig from the created cluster. This provider will be used for deploying the Helm chart to the cluster. (See Pulumi Kubernetes Provider)

    • It deploys a Helm chart provider-openstack from a given Helm chart repository to the Kubernetes cluster. You need to replace https://charts.example.com/ with the actual URL of the Helm chart repository containing provider-openstack. (See Pulumi Helm Chart)

    Step 3: Running the Pulumi Program

    To create the infrastructure, run these commands:

    pulumi up

    Pulumi will show you a preview of the resources that will be created and prompt you to confirm the deployment.

    Step 4: Accessing the Deployed Resources

    After deployment, the Pulumi program exports the name of the Kubernetes cluster and the kubeconfig required to access it. You can use these to interact with your cluster using kubectl or other Kubernetes management tools.

    To see the outputs after the deployment, run:

    pulumi stack output clusterName pulumi stack output kubeconfig

    This will give you the cluster's name and kubeconfig which you can use to check on your Helm deployment, or to manage your cluster further.

    Remember to modify the Helm chart repository URL in the code with the correct one that hosts the provider-openstack Helm chart. If you don't have a specific Helm chart for OpenStack provider, you'll need to create or find one that suits your needs, as this code assumes such a chart exists and is accessible.
