1. Deploy the notification-consumer helm chart on Oracle Kubernetes Engine (OKE)


    To deploy a Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you would need to set up an OKE cluster and then deploy the Helm chart to that cluster. We will walk through both of these steps. Firstly, we'll create an OKE cluster using the oci.ContainerEngine.Cluster resource. Once the cluster is provisioned, we will deploy the notification-consumer Helm chart using the kubernetes.helm.v3.Chart resource.

    Below is a TypeScript program for Pulumi that accomplishes these tasks. The comments in the code will explain what each part does.

    import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // This is the OCI compartment ID where the cluster will be created. // You should replace this with your actual compartment ID. const compartmentId = "ocid1.compartment.oc1..exampleUniqueID"; // Create an Oracle Kubernetes Engine (OKE) cluster. const okeCluster = new oci.ContainerEngine.Cluster("okeCluster", { // Replace with your desired name and settings for the OKE cluster name: "notification-consumer-cluster", compartmentId: compartmentId, kubernetesVersion: "v1.20.8", // Choose a supported version vcnId: "ocid1.vcn.oc1..exampleUniqueID", // This should be the OCID of an existing VCN options: { // Depending on your requirements, you might need to adjust the options serviceLbSubnetIds: ["ocid1.subnet.oc1..exampleUniqueID1", "ocid1.subnet.oc1..exampleUniqueID2"], }, }); // Set up a Kubernetes provider to interact with the OKE cluster. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: okeCluster.kubeconfigs.apply(kubeconfigs => kubeconfigs[0].content), }); // Define the Helm chart for the notification-consumer. const notificationConsumerChart = new k8s.helm.v3.Chart("notification-consumer-chart", { // Replace with the chart name, version, and repository specifics chart: "notification-consumer", version: "1.0.0", // specify the chart version fetchOpts: { // You might need to specify a repository if it's not a stable Helm chart repo: "https://charts.example.com/", }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig. export const kubeconfig = okeCluster.kubeconfigs.apply(kubeconfigs => kubeconfigs[0].content); // Once deployed, you can use the `kubeconfig` file to interact with your Kubernetes cluster using `kubectl`.

    To explain the program:

    • We import the necessary Pulumi packages for working with Oracle Cloud Infrastructure and Kubernetes.
    • The oci.ContainerEngine.Cluster resource initializes an OKE cluster within the specified compartment and virtual cloud network (VCN).
    • After the cluster is created, we set up a k8s.Provider which is how Pulumi interacts with Kubernetes clusters. We pass the cluster's kubeconfig to the provider so Pulumi can authenticate with the cluster.
    • The kubernetes.helm.v3.Chart resource deploys the notification-consumer Helm chart onto our OKE cluster. We specify the version and repository of the chart, but you need to replace these values with the actual chart details.
    • Finally, we export the kubeconfig, allowing you to interact with the OKE cluster using your local kubectl tool.

    To use this Pulumi program:

    1. Replace the placeholder values with your actual OCI identifiers and Helm chart specifications.
    2. Deploy the program using Pulumi CLI commands:
      • Run pulumi up to preview and deploy the changes.
    3. Once deployed, you can use the exported kubeconfig to manage your Kubernetes cluster with kubectl.

    Please ensure that you have the OCI Pulumi provider set up and configured with your credentials before running this program.
