1. Deploy the ibm-websphere-liberty helm chart on Digital Ocean Kubernetes Service


    To deploy the ibm-websphere-liberty Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you would need to create a Kubernetes cluster in Digital Ocean, and then use the Helm chart resource to deploy ibm-websphere-liberty.

    Here's a step-by-step process written in TypeScript, broken down into segments for clarity:

    1. Create a Kubernetes cluster on Digital Ocean: Use the digitalocean.KubernetesCluster resource from the Digital Ocean provider.
    2. Deploy the Helm chart to the cluster: After the cluster is provisioned, use the kubernetes.helm.sh/v3.Chart resource from the Kubernetes provider to deploy the ibm-websphere-liberty Helm chart.

    Below is a Pulumi program in TypeScript:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; const name = "do-cluster"; // Step 1: Create a Kubernetes cluster on Digital Ocean const cluster = new digitalocean.KubernetesCluster(name, { region: "nyc3", version: "latest", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2, }, }); // Step 2: Deploy the Helm chart to the cluster // First, we need to use the kubeconfig from the created cluster to interact with it const provider = new kubernetes.Provider(name, { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Now we can deploy the Helm chart using the Kubernetes provider instance const ibmWebsphereLibertyChart = new kubernetes.helm.v3.Chart("ibm-websphere-liberty", { chart: "ibm-websphere-liberty", // Here you may specify the Helm repository if the chart is not in the default Helm repo // If the chart is in a private repository, you need to add `repo` argument with repository URL // repo: "https://charts.your-repo.com/" // You can specify the version of the chart if necessary // version: "x.x.x", // Values can be provided if required to customize the Helm chart releases // values: { }, }, { provider }); // Export the cluster's kubeconfig and the service URL if it's exposed via a LoadBalancer export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const serviceUrl = ibmWebsphereLibertyChart.getResourceProperty("v1/Service", "ibm-websphere-liberty", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Here's what each part of the program is doing:

    • The digitalocean.KubernetesCluster resource is used to create a new Kubernetes cluster in the "nyc3" region with the latest available version of Kubernetes and a default node pool with 2 nodes of size "s-2vcpu-2gb".
    • The kubernetes.Provider resource sets up the Pulumi Kubernetes provider with the kubeconfig from the Digital Ocean cluster, which allows Pulumi to manage resources in that cluster.
    • The kubernetes.helm.v3.Chart resource deploys the ibm-websphere-liberty Helm chart onto the Kubernetes cluster. It uses the Kubernetes provider we set up earlier.
    • The export statements make the kubeconfig and the IP of the LoadBalancer (if one is created by the chart) accessible outside of Pulumi for use with kubectl or in applications that need to communicate with the cluster.

    Make sure you have Pulumi and the required CLI tools for Digital Ocean (doctl) set up. After running pulumi up, Pulumi will perform the provisioning steps described above.

    The provided Helm chart must be available in a Helm repository that Pulumi can access. If it's a private repository or a custom one, you must provide the repo property with the correct URL value, and if authentication is required, the credentials must be configured accordingly.
