1. Deploy the rancher-vsphere-cpi helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the rancher-vsphere-cpi Helm chart on Oracle Kubernetes Engine (OKE), you will need to follow these high-level steps:

    1. Set up an OKE cluster where you'll deploy the Helm chart.
    2. Install and configure the Pulumi Kubernetes provider to interact with your OKE cluster.
    3. Use the Pulumi Kubernetes provider to deploy the rancher-vsphere-cpi Helm chart to the OKE cluster.

    Below is a Pulumi program written in TypeScript that demonstrates how to accomplish these steps. It assumes that you have already configured the Pulumi CLI and the Oracle Cloud Infrastructure (OCI) provider. This will include creating an OKE cluster, then deploying a Helm chart to it.

    Step-by-Step Guide:

    Install Pulumi CLI and Setup OCI

    Before running the below program, ensure you have the Pulumi CLI installed and that you have correctly set up your Oracle Cloud Infrastructure configuration with the required credentials.

    The Pulumi Program

    This program will:

    • Create a Kubernetes cluster on OKE using the oci.ContainerEngine.Cluster resource.
    • Then, it will deploy the rancher-vsphere-cpi Helm chart on the created cluster using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider.

    Please replace "my-cluster-id" with the appropriate ID for your environment. Also, ensure the Helm chart version and values are set as needed for your specific deployment.

    import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; // Create an OKE cluster. const cluster = new oci.ContainerEngine.Cluster("okeCluster", { // Specify the required properties for your OKE cluster. // Replace placeholder values with the actual data. compartmentId: "oci-compartment-id", kubernetesVersion: "v1.20.8", name: "my-cluster-name", vcnId: "oci-vcn-id", options: { // Define your OKE options. serviceLbSubnetIds: ["oci-lb-subnet-id-1", "oci-lb-subnet-id-2"], // Additional configuration options if needed... }, }); // Once the cluster is ready, we interact with it using the Kubernetes provider. const kubeconfig = cluster.kubeconfig.getContent(); // Using the resulting kubeconfig, create a Provider resource for Pulumi to use. const k8sProvider = new k8s.Provider("okeK8sProvider", { kubeconfig: kubeconfig, }); // Specify the details of the Helm chart, such as repository and version. const rancherVsphereCpiChart = new k8s.helm.v3.Chart("rancher-vsphere-cpi", { chart: "rancher-vsphere-cpi", version: "1.0.0", // Specify the appropriate chart version. fetchOpts: { repo: "https://charts.example.com/", // Specify the Helm chart repository URL. }, namespace: "kube-system", // Rancher typically deploys into the kube-system namespace. }, { provider: k8sProvider }); // Export the kubeconfig and OKE cluster details to interact with the cluster using kubectl. export const kubeconfigOutput = kubeconfig; export const clusterId = cluster.id; export const clusterName = cluster.name;

    Make sure you review and adjust the above program according to your specific Rancher and OCI configurations. This includes the compartmentId, kubernetesVersion, vcnId, and the subnets under serviceLbSubnetIds.

    After the code is ready, you can deploy your infrastructure by running pulumi up from your command line within the directory of your Pulumi project. This will provision the cluster and then deploy the specified Helm chart.

    For additional details on using OCI with Pulumi:

    • Visit the OCI Container Engine for Kubernetes resource documentation for more options and information.
    • Check out the Helm Chart resource documentation from Pulumi's Kubernetes provider to learn more about deploying Helm charts with Pulumi.
