1. Deploy the swaggereditor-dashboard helm chart on Digital Ocean Kubernetes Service


    To deploy the Swagger Editor dashboard using the Helm chart on DigitalOcean's Kubernetes service, you need to follow these steps:

    1. Provision a DigitalOcean Kubernetes cluster.
    2. Configure the Kubernetes provider to connect to your newly created cluster.
    3. Use the Helm provider to deploy the Swagger Editor dashboard on your Kubernetes cluster.

    Before proceeding, make sure you have the following prerequisites in place:

    • A Pulumi account and the Pulumi CLI installed.
    • Access to a DigitalOcean account and the doctl CLI, with the necessary permissions to create Kubernetes clusters.
    • The credentials for DigitalOcean and Kubernetes set in your environment or Pulumi stack configuration.

    Below is a Pulumi program written in TypeScript that accomplishes these tasks:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Provision a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-k8s-cluster', { region: 'nyc1', // specify the region you want to deploy your cluster in version: 'latest', // use the latest available version of Kubernetes nodePool: { name: 'default', size: 's-2vcpu-2gb', // select the appropriate size for your workloads nodeCount: 2, // specify the number of nodes in the node pool }, }); // Step 2: Configure the Kubernetes provider using the output from the DO cluster const k8sProvider = new k8s.Provider('do-k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the swaggereditor-dashboard Helm chart on the Kubernetes cluster const swaggerEditorChart = new k8s.helm.v3.Chart('swaggereditor-dashboard', { chart: 'swagger-editor', // ensure that this is the correct name of the Helm chart version: 'latest', // specify the chart version you want to deploy fetchOpts: { repo: 'http://petstore.swagger.io', // replace with the correct repository URL for the Helm chart }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and dashboard service endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const swaggerEditorDashboardEndpoint = swaggerEditorChart.getResourceProperty('v1/Service', 'swaggereditor-dashboard', 'status');

    Let's break down what each part of this program does:

    • Step 1: We create a new DigitalOcean Kubernetes cluster using the digitalocean.KubernetesCluster resource. We need to specify parameters such as the region, Kubernetes version, and details about the node pool like its size and node count.

    • Step 2: Next, we configure the Pulumi Kubernetes provider to connect to the Kubernetes cluster using the kubeconfig output from the newly created cluster. This provider will be used to deploy resources to our cluster.

    • Step 3: Lastly, we deploy the Swagger Editor dashboard Helm chart using k8s.helm.v3.Chart. The chart is identified by its name (swagger-editor) which you might need to change to match the name in the Helm repository. Similarly, you should specify the correct Helm repository URL in the fetchOpts.repo field.

    Lastly, we export the kubeconfig file to easily access our cluster using kubectl and the Swagger Editor dashboard service endpoint, so we know how to access our Swagger Editor once it is deployed.

    Please note: The URLs and names used in the Helm chart and repository configurations are placeholders and should be replaced with the correct ones. You will need to find the appropriate Helm repository where the Swagger Editor chart is hosted or use your own if you have packaged it yourself.
