1. Deploy the openshift-jenkins helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the openshift-jenkins Helm chart on Oracle Kubernetes Engine (OKE), we'll use the oci Pulumi provider to interact with Oracle Cloud Infrastructure and the kubernetes provider to manage the Kubernetes resources, including the Helm chart.

    First, you will need to set up your Oracle Cloud Infrastructure account and create an OKE cluster if you don't already have one. Once you have your OKE cluster ready, you will also need to configure kubectl with your cluster's access details. Make sure the ~/.kube/config file contains the necessary configuration.

    Here's a detailed breakdown of the steps we're going to follow in the Pulumi program:

    1. Set up the OCI provider so that Pulumi can communicate with your Oracle Cloud account.
    2. Create a Kubernetes provider instance that points to your previously configured OKE cluster. This provider instance will be used to deploy resources to your cluster.
    3. Deploy the openshift-jenkins Helm chart to your OKE cluster using the kubernetes.helm.v3.Chart resource.

    The program below is written in TypeScript, and you should be running it in a directory where a Pulumi project is set up. The Pulumi CLI provides commands to create a new project and to perform deployments.

    Here's what the Pulumi program looks like:

    import * as pulumi from '@pulumi/pulumi'; import * as oci from '@pulumi/oci'; import * as k8s from '@pulumi/kubernetes'; // Set your OKE cluster OCID here const okeClusterId = 'ocid1.cluster.oc1..exampleuniqueID'; // Get the kubeconfig for the existing OKE cluster const kubeconfig = oci.containerengine.getClusterKubeconfig({ clusterId: okeClusterId, }); // Create a Kubernetes provider pointing to the cluster provided by OCI const k8sProvider = new k8s.Provider('okeK8sProvider', { kubeconfig: kubeconfig.config, }); // Specify the chart details for the openshift-jenkins Helm chart. const openshiftJenkinsChart = new k8s.helm.v3.Chart('openshift-jenkins', { repo: 'the-repository', // Replace with the actual Helm repository chart: 'openshift-jenkins', version: 'the-version', // Replace with the specific chart version, if required // You can specify the values for the chart using 'values' or 'valueYamlFiles' values: { // Provide any specific configuration values here // For example: // master: { adminPassword: 'secret123' } }, }, { provider: k8sProvider }); // Export the Chart status export const helmChartStatus = openshiftJenkinsChart.status;

    Please update repo, chart, and version accordingly to match the Helm repository where the openshift-jenkins chart is located. Additionally, you'll need to provide the actual ocid for the cluster in okeClusterId. You can customize the values object to configure openshift-jenkins as per your requirements.

    Note that if your OKE Kubernetes cluster required specific credentials or setup outside of the kubeconfig, such as a Tiller service account or specific namespaces, you would need to include those in the script as well. The Helm chart repository URL should be replaced by the actual URL where the openshift-jenkins chart is hosted.

    To run this program, you will execute it through the Pulumi CLI:

    1. Run pulumi up to preview and deploy the changes.
    2. Confirm the deployment to proceed when prompted.

    If you have not previously selected a stack, you'd need to run pulumi stack init to create a new stack. A stack in Pulumi is an isolated, independently configurable instance of a Pulumi program.

    Remember, you must have Pulumi installed and configured on your machine to run this code, along with an account and the OCI CLI configured for Oracle Cloud Infrastructure.
