1. Deploy the vipien helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the vipien Helm chart on Oracle Kubernetes Engine (OKE), we'll follow these steps using Pulumi:

    1. Set up the Oracle Kubernetes cluster resource using oci.ContainerEngine.Cluster.
    2. Install the Helm chart on the cluster using kubernetes.helm.sh/v3.Chart.

    We'll begin by creating a new Pulumi project and importing the necessary packages. Ensure you have Pulumi installed, appropriate oci cloud account credentials are set, and the OKE cluster is already provisioned or that you have the required permissions to create one.

    Below is the Pulumi program written in TypeScript which:

    • Defines an OKE cluster (skipped if already provisioned)
    • Configures Kubernetes provider to deploy resources on OKE
    • Deploys the vipien Helm chart to the cluster

    First, install the necessary dependencies:

    # Install the Pulumi OCI provider package $ npm install @pulumi/oci # Install the Pulumi Kubernetes provider package $ npm install @pulumi/kubernetes

    Now you can use the following TypeScript code:

    import * as oci from "@pulumi/oci"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Define the OCI cluster - this assumes an existing VCN and subnet ids configured. const cluster = new oci.ContainerEngine.Cluster("okeCluster", { compartmentId: pulumi.config.require("compartmentId"), kubernetesVersion: "v1.20.8", name: "vipienOkeCluster", options: { // Add your specific options here serviceLbSubnetIds: ["<subnet-id-1>", "<subnet-id-2>"], // Replace with actual subnet IDs }, vcnId: pulumi.config.require("vcnId"), // ... Add any other required and optional properties }); // Configure the Kubernetes provider to connect to the OCI cluster const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: cluster.kubeConfig.content.apply(JSON.stringify), }); // Deploy the vipien Helm chart on the OKE cluster const vipienChart = new kubernetes.helm.v3.Chart("vipienChart", { chart: "vipien", // Optionally, specify the Helm repo where your chart is located if it's not a public one // repo: "<your-helm-repo-url>", values: { // Specify values for the Helm chart as needed // service: { // type: "LoadBalancer" // }, // ... more value overrides for your chart }, }, { provider: k8sProvider }); // Make sure to pass the k8s provider we configured above // Export the Kubeconfig and VIPien service endpoint if needed export const kubeconfig = cluster.kubeConfig.content; export const vipienEndpoint = vipienChart.getResourceProperty("v1/Service", "vipien", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Make sure to replace placeholders like <subnet-id-1>, <subnet-id-2>, and provide the actual compartmentId and vcnId as necessary. If your Helm chart is in a private repository, provide the repository's URL in the repo field.

    This program achieves the following:

    • Defines a new Oracle Kubernetes Engine cluster named "vipienOkeCluster" using the OCI provider.
    • Sets up a Kubernetes provider to manage resources in the newly created OKE cluster, which requires the kubeConfig generated by the cluster resource.
    • Deploys the vipien Helm chart to the OKE cluster using the standard Helm Chart resource provided by Pulumi's Kubernetes provider. If additional customization is needed for the Helm chart deployment (commonly through values), they can be specified in the values parameter.

    Remember to adjust your configurations based on the actual requirements of your setup. You may need to modify the configurations, such as version numbers or subnet IDs, depending on your use case and Oracle cloud environment setup.

    After you've tested and verified that the program meets your requirements, run the Pulumi CLI commands to deploy the resources:

    # Login to Pulumi. This stores the Pulumi state, which tracks resource deployment status $ pulumi login # Create a new Pulumi Stack, which is an isolated environment for your resources $ pulumi stack init dev # Preview the changes that would be made by your program $ pulumi preview # Deploy the resources specified in your program $ pulumi up

    You’ll be prompted to confirm the deployment. On approval, Pulumi will carry out the deployment, and you will see updates in your terminal detailing the deployment process. After it’s complete, you can access your deployed vipien service using the endpoint that was exported by the program.
