1. Deploy the workshop-operator helm chart on Digital Ocean Kubernetes Service


    Deploying a Helm chart to a Kubernetes cluster on Digital Ocean is a two-step process:

    1. Provision a Kubernetes cluster on Digital Ocean.
    2. Deploy the Helm chart to the provisioned cluster.

    To provision a Digital Ocean Kubernetes (DOKS) cluster, we'll use the digitalocean.KubernetesCluster resource from Digital Ocean's Pulumi provider. Once the cluster is up and running, we'll configure kubectl to connect to it by setting the kubeconfig.

    Then, to deploy the Helm chart, we'll use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. We'll specify the name of the Helm chart (workshop-operator in this case) along with any values you would like to customize.

    Below is a full TypeScript program that demonstrates how to perform these steps. Each part is commented to help you understand the process:

    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 your cluster version: 'latest', // Specify the version of Kubernetes you want to use nodePool: { name: 'default', size: 's-2vcpu-2gb', // Choose the size of your nodes nodeCount: 2, // Specify the number of nodes in the node pool }, }); // Export the kubeconfig to access the cluster. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Create a Kubernetes provider instance using the kubeconfig from the Digital Ocean cluster. const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the workshop-operator Helm chart on the Digital Ocean cluster. const helmChart = new kubernetes.helm.v3.Chart('workshop-operator-chart', { chart: 'workshop-operator', // The name of the chart in the Helm repository fetchOpts: { repo: 'http://charts.your-company.com', // Replace with the URL of your Helm chart's repository, }, }, { provider: k8sProvider }); // Associate the Helm chart with the Kubernetes provider. // Optionally, you can export the Helm chart deployment status export const helmChartStatus = helmChart.status;

    In this program:

    • We first create a Digital Ocean Kubernetes cluster in the nyc3 region with the latest version of Kubernetes. We specify the node size and count which can be adjusted to your needs.
    • We export the kubeconfig from the newly created cluster, which you'll need to interact with your Kubernetes cluster using kubectl.
    • We create a Pulumi Kubernetes provider that uses the kubeconfig from our DOKS cluster.
    • Finally, we define a Chart resource which represents the Helm chart we wish to deploy. We specify the chart name workshop-operator and the repository where the chart is located.

    The fetchOpts property in the Chart resource definition should be replaced with the specific details of your Helm chart's location. Ensure to put the URL of the repository where your workshop-operator Helm chart is hosted. If you have additional configuration values you would like to provide to your Helm chart, you can specify them in the values property of the Chart resource.

    Remember to install the necessary Pulumi packages and setup pulumi CLI before running the code. Also, you'll need to have access to a Digital Ocean account and Kubernetes configured with the necessary credentials.

    This is a general program and modifications may be required depending on the specifics of the Helm chart you are deploying and your Digital Ocean settings.
