1. Deploy the nuxt2-spa helm chart on Oracle Kubernetes Engine (OKE)


    To deploy a Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, we need to understand a few core components:

    1. Oracle Kubernetes Engine (OKE) Cluster: This is the Oracle Cloud managed Kubernetes service where we will deploy our Helm Chart.
    2. Helm Chart: This is a packaged set of pre-configured Kubernetes resources that can be deployed as a single unit. In your case, you want to deploy a nuxt2-spa Helm chart, which will contain the configuration for a Nuxt.js SPA (Single Page Application).

    Steps to Deploy a Helm Chart on OKE

    1. Provision an OKE Cluster: First, we need to create an OKE cluster. If you already have one, you can skip this step and use your existing cluster's kubeconfig.

    2. Setup Helm Release Resource: After setting up the OKE cluster, we use the kubernetes.helm.v3.Chart resource to deploy the nuxt2-spa Helm chart into our cluster. This resource allows us to specify the details of the Helm release like chart name, version, and any custom values we want to override.

    Pulumi Program

    Here is a Pulumi TypeScript program that illustrates deploying the nuxt2-spa Helm chart on OKE:

    import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; // Replace these with the appropriate values for your environment. const compartmentId = "your-compartment-id"; const chartRepo = "your-chart-repo"; const chartVersion = "your-chart-version"; const releaseName = "nuxt2-spa-release"; // Create an OKE cluster (if necessary). const cluster = new oci.containerengine.Cluster("my-cluster", { // Cluster configuration ... compartmentId: compartmentId, // Other cluster configurations such as VCN, subnet, etc. }); // Once the cluster is provisioned, we use the kubeconfig to interact with it via Pulumi. const kubeconfig = cluster.kubeconfig.getContent(); // Create a provider instance that uses the above kubeconfig. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig }); // Deploy the 'nuxt2-spa' Helm chart to the cluster. const nuxt2Spa = new k8s.helm.v3.Chart(releaseName, { chart: "nuxt2-spa", version: chartVersion, fetchOpts:{ repo: chartRepo, }, }, { provider: k8sProvider }); // Export the URL of the deployed Nuxt.js SPA (assuming the service type is LoadBalancer). export const spaUrl = nuxt2Spa.getResourceProperty("v1/Service", "nuxt2-spa-svc", "status").apply(status => status.loadBalancer.ingress[0].ip);


    The program begins by importing the necessary Pulumi oci and kubernetes packages. We've defined a few placeholders such as compartmentId, chartRepo, and chartVersion which should be filled with your specific details.

    • We create an OKE cluster using the oci.containerengine.Cluster resource. This step involves setting various OKE-specific configurations like compartment ID, networking, and others. You'll need to fill in those details based on your OCI setup.

    • We obtain the kubeconfig from the created cluster, which allows us to interact with the Kubernetes API server hosted on OCI.

    • We set up the Kubernetes provider using the obtained kubeconfig. This tells Pulumi how to communicate with your cluster.

    • We then declare a Helm chart resource using k8s.helm.v3.Chart. In this resource, we specify the details for the Helm release including the name of the chart (nuxt2-spa), its version, and the repository where it can be found.

    • Once the chart is deployed, we export the URL where the SPA is accessible. This assumes that your Helm chart creates a Kubernetes Service of type LoadBalancer which provides an external IP to access your application.

    Before Running the Program

    Make sure you have:

    • Installed Pulumi CLI and set up the OCI provider.
    • Authenticated with OCI (Oracle Cloud Infrastructure).
    • Access to an OCI compartment and permissions to create resources.

    To run the above Pulumi program, you would execute the following commands:

    pulumi stack init dev # Initialize a new stack called 'dev' pulumi up # Deploy the stack

    This will prompt you for confirmation before proceeding to make any changes. Once confirmed, Pulumi will execute the program and display the progress and results in the terminal.
