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


    To deploy the Zinc Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, we'll need to perform a series of steps. These steps include setting up an OKE cluster, configuring Kubernetes provider to interact with the cluster, and finally deploying the Zinc Helm chart.

    Here's what each step entails:

    1. Setting Up an OKE Cluster: First, we need an OKE cluster where our application will run. This involves using the oci.ContainerEngine.Cluster resource from the oci package. We will define the necessary properties for our OKE cluster, such as its name, Kubernetes version, and the Virtual Cloud Network (VCN) ID it should use.

    2. Configuring Kubernetes Provider: After creating the cluster, we'll instantiate a Kubernetes provider that enables Pulumi to communicate with the Kubernetes cluster. This step may involve setting the provider with the appropriate kubeconfig that allows Pulumi to manage Kubernetes resources on OKE.

    3. Deploying the Zinc Helm Chart: With the provider configured, we'll use the kubernetes.helm.v3.Chart resource from the kubernetes package to deploy the Zinc Helm chart to our cluster. This involves setting the chart name, repository, and any other configuration needed by Zinc.

    Let's write the Pulumi TypeScript program that performs these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Setting up an OKE cluster const cluster = new oci.containerengine.Cluster("my-cluster", { // Replace the following attributes with your actual VCN ID and compartment ID // plus any other specific configurations required for your cluster compartmentId: "YOUR_COMPARTMENT_ID", vcnId: "YOUR_VCN_ID", kubernetesVersion: "v1.20.11", options: { serviceLbSubnetIds: [ "YOUR_SUBNET_ID1", "YOUR_SUBNET_ID2" ] } }); // Step 2: Configuring Kubernetes Provider // This step assumes you have set up your OCI provider configuration with the correct // credentials. It uses the output of the OKE cluster to configure the Kubernetes provider. const k8sProvider = new k8s.Provider("my-k8s-provider", { kubeconfig: cluster.kubeconfig.apply(kubeconfig => kubeconfig.content), }); // Step 3: Deploying the Zinc Helm Chart const zincHelmChart = new k8s.helm.v3.Chart("zinc-chart", { chart: "zinc", // If the chart is from a specific Helm repository, you should also specify the `repo` attribute; // if it's a local chart, use the `path` attribute instead // repo: "https://charts.example.com/", // You can specify the version of the chart and any values that you might want to override // version: "1.2.3", // values: { ... }, }, { provider: k8sProvider }); // Export the kubeconfig to access the cluster with kubectl export const kubeconfigContent = cluster.kubeconfig.apply(kubeconfig => kubeconfig.content);

    Here's a breakdown of the program:

    • We start by importing the necessary Pulumi packages. The oci package is used to interact with Oracle Cloud Infrastructure resources, and the kubernetes package allows us to handle Kubernetes resources.

    • In the first step, we create a new OKE cluster by instantiating an oci.containerengine.Cluster. You need to replace YOUR_COMPARTMENT_ID and YOUR_VCN_ID with the appropriate IDs from your Oracle Cloud account. Also, provide subnet IDs within serviceLbSubnetIds.

    • Next, we configure a Kubernetes provider using the kubeconfig output of the OKE cluster. This kubeconfig is what allows Pulumi to communicate with the Kubernetes cluster and manage resources.

    • In the third step, we deploy the Zinc Helm chart using the k8s.helm.v3.Chart resource. The chart property specifies the name of the Helm chart — in this case, "zinc". If the chart is stored in a Helm repository, specify the repository URL with the repo attribute; otherwise, for a local chart, use the path attribute.

    • Finally, we export the kubeconfig content, which can be used to access the Kubernetes cluster with kubectl. This is useful for manual inspections or for operations that you want to perform outside of Pulumi.

    To run this Pulumi program:

    1. Ensure you have Pulumi CLI installed and configured with access to your Oracle Cloud environment.
    2. Save the above TypeScript code to a file named index.ts.
    3. Run pulumi up in your terminal to preview and deploy the changes. Pulumi CLI will guide you through the process.

    Please replace placeholders such as YOUR_COMPARTMENT_ID, YOUR_VCN_ID, and the subnet IDs with actual values from your Oracle Cloud setup before running the program. Additionally, if the Zinc Helm chart requires specific values, you should include them in the values property of the Helm chart resource.
