1. Deploy the keycloak-config helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the keycloak-config Helm chart on Oracle Kubernetes Engine (OKE), we'll follow these steps:

    1. Set up an OKE cluster: Before deploying any applications, an OKE cluster must exist. You can create an OKE cluster using Pulumi with the oci.ContainerEngine.Cluster resource.

    2. Configure Kubernetes provider for OKE: After the cluster has been created, we need to set up the Kubernetes provider to point to the newly created OKE cluster.

    3. Deploy the Helm chart: Once the Kubernetes provider is configured with the OKE cluster's credentials, we can use the kubernetes.helm.v3.Chart resource to deploy the keycloak-config Helm chart to the cluster.

    Below is a Pulumi program in TypeScript that outlines these steps. For illustration purposes, I will assume that you have the necessary Oracle Cloud Infrastructure (OCI) permissions and credentials already set up. If you are missing the credentials setup, you need to do that before running this Pulumi program.

    import * as pulumi from "@pulumi/pulumi"; import * as oci from "@pulumi/oci"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create an Oracle Kubernetes Engine (OKE) cluster // Here, we're creating a new VCN and an OKE cluster within it. // Replace compartmentId and other configurations with your own details. const vcn = new oci.core.Vcn("myVcn", { compartmentId: "<Your-Compartment-ID>", cidrBlock: "10.0.0.0/16", displayName: "myVcn", }); const subnet = new oci.core.Subnet("mySubnet", { compartmentId: "<Your-Compartment-ID>", vcnId: vcn.id, cidrBlock: "10.0.1.0/24", displayName: "mySubnet", }); // ... additional VCN and security configuration as needed const cluster = new oci.containerengine.Cluster("myOkeCluster", { compartmentId: "<Your-Compartment-ID>", vcnId: vcn.id, // ... other required OKE cluster configuration }); // Step 2: Set up the Kubernetes provider to connect to the OKE // To obtain the kubeconfig for the cluster, you would typically use the OCI CLI or console. // It is important to ensure that access to the cluster is secured and that the kubeconfig // is stored and handled securely. const k8sProvider = new kubernetes.Provider("myK8sProvider", { kubeconfig: pulumi.interpolate`<Your-Kubeconfig-Contents>`, }); // Step 3: Deploy the keycloak-config Helm chart to the OKE cluster // You need to provide the Helm chart repository that contains the keycloak-config chart // In this example, we're pulling the chart from a hypothetical repository at 'https://charts.myorg.com' const keycloakChart = new kubernetes.helm.v3.Chart("keycloakConfig", { chart: "keycloak-config", version: "<Chart-Version>", // Specify the chart version you want to deploy fetchOpts: { repo: "https://charts.myorg.com", }, }, { provider: k8sProvider }); // Outputs export const kubeconfig = cluster.kubeconfig; export const keycloakChartVersion = keycloakChart.version;

    Here's what each part of this code is doing:

    • The oci.core.Vcn and oci.core.Subnet resources are used to set up the network infrastructure needed for OKE.
    • The oci.containerengine.Cluster is the actual OKE cluster resource. You should replace the placeholder values with your specific OCI configuration details.
    • The kubernetes.Provider in the program is for the OKE cluster. It utilizes the cluster's kubeconfig to interact with the cluster.
    • The kubernetes.helm.v3.Chart resource takes the name of the Helm chart (keycloak-config) and a repository URL where the chart can be found. You'll have to specify the version you want to deploy. It's then associated with the k8sProvider, ensuring that it gets deployed onto the OKE cluster you've provisioned.

    Before you run the above program, ensure that:

    • You replace <Your-Compartment-ID> with the OCI compartment ID where you want the resources created.
    • You replace <Your-Kubeconfig-Contents> with the kubeconfig content for your OKE cluster.
    • You specify the version of the keycloak-config chart you wish to deploy in <Chart-Version>.
    • The Helm repo URL (https://charts.myorg.com) should be the real URL where your desired Helm chart is located.

    Once you apply this Pulumi program with pulumi up, the OKE cluster will be provisioned, and the keycloak-config Helm chart will be deployed to it.
