1. Deploy the ibm-process-mining-operator helm chart on Digital Ocean Kubernetes Service


    To deploy the ibm-process-mining-operator Helm chart on Digital Ocean's Kubernetes service using Pulumi, we will first need to create a Kubernetes cluster on Digital Ocean. After we've set up our cluster, we can then proceed to deploy the Helm chart to it.

    Here is the high-level overview of the steps we'll take to achieve this with Pulumi and TypeScript:

    1. Create a new Digital Ocean Kubernetes cluster using Pulumi's Digital Ocean provider.
    2. Use the Pulumi Kubernetes provider to install the ibm-process-mining-operator Helm chart on the cluster we created.

    Before you run Pulumi code, ensure you have the following prerequisites met:

    • Pulumi CLI installed.
    • Digital Ocean access token configured for Pulumi, typically using pulumi config set digitalocean:token <YOUR_TOKEN> command.
    • Authenticated with Kubernetes cluster, usually by setting the KUBECONFIG environment variable or using default location ~/.kube/config.

    Now, let's go through the Pulumi code required for each step. I'll include comments explaining each part of the program.

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Creating the Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "latest", nodePool: { name: "default", size: "s-2vcpu-2gb", // You can change the size as per your requirement nodeCount: 2, // The number of nodes you want in your node pool }, }); // Step 2: Deploying the Helm chart on the Kubernetes cluster const chart = new k8s.helm.v3.Chart("ibm-process-mining-operator", { chart: "ibm-process-mining-operator", version: "1.0.0", // specify the version, if known // If the Helm chart is hosted in a custom Helm repo, specify the `repo` property here namespace: "default", // specify the Kubernetes namespace }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Exporting the Kubernetes cluster name and endpoint export const clusterName = cluster.name; export const clusterEndpoint = cluster.endpoint;

    In the code above:

    • We create a Digital Ocean Kubernetes cluster with the name do-cluster. The size of the nodes is s-2vcpu-2gb, and we want 2 nodes in our node pool. The region is set to nyc3, but you can select your desired region.
    • Once the cluster is created, we set up a Pulumi Kubernetes provider that uses the kubeconfig of the new Digital Ocean cluster.
    • We then deploy the ibm-process-mining-operator Helm chart to the cluster. Please replace 1.0.0 with the actual version of the Helm chart that you want to use. If the Helm chart is not available in the default Helm repo, you may need to pass the repo property to specify the Helm repository URL.
    • Finally, we export the name and endpoint of the Kubernetes cluster so that they can be easily retrieved after deployment.

    To deploy this code, save it to a file called index.ts and then run pulumi up from the command line, which will set up the Digital Ocean Kubernetes cluster and deploy the Helm chart into it.
