1. Deploy the kubeseal-webgui helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the kubeseal-webgui Helm chart on Oracle Kubernetes Engine (OKE), you would need to perform the following steps:

    1. Set up the OKE cluster and OCI (Oracle Cloud Infrastructure) configuration.
    2. Install the Helm chart for your application, kubeseal-webgui, onto the OKE cluster.

    This Pulumi program in TypeScript below demonstrates these steps. The program assumes that you have already configured your Oracle Cloud Infrastructure (OCI) provider and Pulumi to use your OCI credentials.

    First, we make sure to import the necessary Pulumi packages:

    • @pulumi/oci is used to work with Oracle Cloud Infrastructure, which includes creating and managing a Kubernetes cluster.
    • @pulumi/kubernetes allows us to work with Kubernetes resources and Helm charts easily.

    In the Pulumi program, we define an OCI Kubernetes cluster by creating an instance of oci.ContainerEngine.Cluster. This resource will configure the Kubernetes cluster in Oracle's cloud.

    Next, we install the kubeseal-webgui Helm chart onto our cluster. We do this by creating a kubernetes.helm.v3.Chart resource in Pulumi. This Pulumi resource represents a Helm chart, and it includes properties such as repo, chart, and version that specify where to find the Helm chart and which version to use.

    Inside the program, comments explain what each step is doing. At the end of the program, we will export the Kubernetes cluster endpoint and the Helm chart name as stack outputs, which can be used to access the deployed application.

    Let's proceed with the Pulumi TypeScript program:

    import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; // Create an OCI Kubernetes cluster (OKE) const cluster = new oci.ContainerEngine.Cluster("myCluster", { // Specify necessary configuration for OKE cluster compartmentId: "<OCI Compartment ID>", // replace with your OCI Compartment ID kubernetesVersion: "v1.21.4", // specify the version of Kubernetes to use name: "kubeseal-webgui-oke-cluster", options: { // Define options for the cluster // ...add OKE cluster options here }, vcnId: "<VcnId>", // replace with your VCN ID // ...add additional OKE configuration options as needed }); // Define the provider for deploying the Helm chart into our OKE cluster const k8sProvider = new k8s.Provider("okeK8sProvider", { kubeconfig: cluster.kubeconfig, // Use the kubeconfig output from the OKE cluster }); // Deploy the `kubeseal-webgui` Helm chart onto the OKE cluster const chart = new k8s.helm.v3.Chart("kubesealWebguiChart", { chart: "kubeseal-webgui", // Specify the Helm repository URL that hosts the `kubeseal-webgui` chart fetchOpts: { repo: "<Helm Repository URL>", // replace with Helm repository URL hosting `kubeseal-webgui` }, // Set any required Helm values here; for example: // values: { // service: { // type: "LoadBalancer" // } // }, // The following property specifies that the Helm chart resources // should be managed by the k8sProvider we defined, which is linked // to the OKE cluster we created }, { provider: k8sProvider } ); // Output the Kubernetes cluster endpoint and the Helm chart name export const clusterEndpoint = cluster.endpoints.apply(e => e.kubernetes); export const helmChartName = chart.metadata.apply(m => m.name);

    To run this Pulumi program:

    • Install the required Pulumi packages by running npm install @pulumi/oci @pulumi/kubernetes.
    • Replace placeholders in the code with appropriate OCI compartment and VCN IDs, and if required, Helm repository URL.
    • Run pulumi up to deploy the resources specified in the program.

    Please note that this code assumes the kubeseal-webgui chart is available in the specified Helm repository and that all necessary values and configurations for the OKE cluster and the Helm chart are specified correctly. If kubeseal-webgui requires specific configuration, be sure to provide it within the values property of the Helm chart resource in the Pulumi program.
