1. Deploy the voltha-adapter-simulated helm chart on Digital Ocean Kubernetes Service


    To deploy the voltha-adapter-simulated Helm chart on a DigitalOcean Kubernetes Service (DOKS) using Pulumi, you'll first need to create a DOKS cluster and then deploy the chart to it. Below is a detailed guide and a Pulumi TypeScript program to accomplish this.


    Before you begin, make sure you have the following prerequisites met:

    1. Pulumi CLI installed and configured with your DigitalOcean token.
    2. Access to the voltha-adapter-simulated Helm chart and its repository information.

    Creating a DigitalOcean Kubernetes Cluster:

    The first resource we will define is a KubernetesCluster from the digitalocean package. This represents a Kubernetes cluster in DigitalOcean. The cluster will be configured with a name, region, version, and node pool details.

    Deploying the Helm Chart:

    Once the Kubernetes cluster is up and running, we'll deploy the Helm chart using the Chart resource from the kubernetes package.

    The Chart resource requires several inputs:

    • chart: The name of the chart, in this case, voltha-adapter-simulated.
    • repo: The Helm chart repository URL where the chart can be found.
    • version: (Optional) The specific version of the Helm chart to deploy.
    • values: (Optional) Configuration overrides that correspond to the contents of the Helm chart's values.yaml file.

    Pulumi Program Structure:

    Here's the structure of our Pulumi program:

    1. Import necessary Pulumi libraries.
    2. Create a new DigitalOcean Kubernetes cluster.
    3. Deploy the voltha-adapter-simulated Helm chart to the cluster.

    Let's look at the complete program:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; // Step 1: Create a new DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: '1.21.5-do.0', nodePool: { name: 'default', size: 's-2vcpu-2gb', nodeCount: 2, // Specify the number of nodes in the node pool }, }); // Step 2: Configure the DigitalOcean provider to deploy resources in the created cluster const kubeProvider = new kubernetes.Provider('do-k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the `voltha-adapter-simulated` Helm chart on the created cluster const helmChart = new kubernetes.helm.v3.Chart('voltha-simulated-chart', { chart: 'voltha-adapter-simulated', // Replace `REPO_URL` with the actual repository URL of the `voltha-adapter-simulated` Helm chart fetchOpts: { repo: 'REPO_URL', }, // Uncomment and modify the following if you need to pass specific values to the Helm chart // values: { // key: "value", // Replace with actual configuration keys and values // }, }, { provider: kubeProvider }); // Export the kubeconfig and the public endpoint of the Kubernetes cluster export const kubeConfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;

    In this program:

    • A DigitalOcean Kubernetes cluster named do-cluster is created with the specified version and node count.
    • A kubeProvider is initialized using the cluster's kubeconfig. This provider is used for deploying Kubernetes resources into the cluster.
    • The voltha-adapter-simulated Helm chart is deployed using the Chart resource. Make sure to replace 'REPO_URL' with the actual Helm repository URL.
    • The Kubeconfig and cluster endpoint are exported, which can be used to interact with the cluster using tools like kubectl.

    To run this Pulumi program, save the code to a index.ts file, run pulumi up, and follow the prompts from the Pulumi CLI to deploy your infrastructure.
