1. Deploy the anaconda-nginx helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the Anaconda-Nginx Helm chart on Oracle Kubernetes Engine (OKE), you'll first need to ensure you have an OKE cluster running and that you have configured kubeconfig correctly to communicate with your cluster.

    In this Pulumi program, we'll make use of the oci.ContainerEngine.Cluster resource to define an OKE cluster and then use the kubernetes.helm.sh/v3.Chart resource to deploy the Anaconda-Nginx Helm chart to that cluster.

    First, let's look at the high-level steps:

    1. Create the OKE Cluster: Define an OKE cluster using Pulumi's OCI provider.
    2. Deploy the Helm Chart: Deploy the Anaconda-Nginx Helm chart to the cluster using Pulumi's Kubernetes provider.

    Here's a detailed 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: Define your OKE Cluster // Replace the following placeholders with the actual values: const compartmentId = "ocid1.compartment.oc1..your-compartment-id"; const vcnId = "ocid1.vcn.oc1..your-vcn-id"; const kubernetesVersion = "v1.21.5"; // choose a version that OKE supports const okeCluster = new oci.ContainerEngine.Cluster("anacondaCluster", { compartmentId: compartmentId, kubernetesVersion: kubernetesVersion, name: "anaconda-cluster", vcnId: vcnId, options: { serviceLbSubnetIds: [], // Fill in with actual subnet OCIDs admissionControllerOptions: { isPodSecurityPolicyEnabled: false, }, }, }); // Step 2: Define a Kubernetes Provider that uses kubeconfig from the generated OKE Cluster const k8sProvider = new k8s.Provider("okeK8s", { kubeconfig: okeCluster.kubeConfigs.apply(kubeConfig => kubeConfig[0].content), }); // Step 3: Deploy the Helm Chart using the kubernetes.helm.sh/v3.Chart resource const anacondaHelmChart = new k8s.helm.v3.Chart("anacondaNginx", { chart: "anaconda-nginx", fetchOpts: { repo: "https://charts.example.com/", // The URL of the Helm chart repository }, version: "1.0.0", // The version of the Helm chart }, { provider: k8sProvider }); // Use the OKE based k8s provider // Export the cluster's name and Kubeconfig (as a secret) export const clusterName = okeCluster.name; export const kubeconfig = pulumi.secret(okeCluster.kubeConfigs.apply(kc => kc[0].content));

    Explanation:

    • OCI OKE Cluster: The oci.ContainerEngine.Cluster resource is used to create an OKE cluster. You'll have to provide the compartmentId, vcnId, and other properties as per your requirements and Oracle's policies.

    • Kubernetes Provider: The k8s.Provider resource sets up the Kubernetes provider with the kubeconfig generated by the OKE cluster, paving the way for you to deploy applications.

    • Helm Chart Deployment: The k8s.helm.v3.Chart resource manages the deployment of the Helm chart. You will provide the name of the chart (anaconda-nginx), and optionally the repo URL where the chart is hosted, as well as the chart's version.

    • Exports: We export the cluster name and kubeconfig so that you can easily retrieve them from the command line using pulumi stack output. The kubeconfig is marked as a secret because it contains sensitive information.

    Before you run this program, make sure that you are logged in to the OCI provider with appropriate permissions. You can execute this Pulumi program by running pulumi up, which will provision the resources as per your specifications in the code above.
