1. Deploy the bitwarden helm chart on Oracle Kubernetes Engine (OKE)


    Deploying the Bitwarden Helm Chart on Oracle Kubernetes Engine (OKE) requires several steps: setting up the Kubernetes cluster, configuring Helm for deployment, and then deploying the Bitwarden Helm chart. In this Pulumi program written in TypeScript, we will use the Oracle Cloud Infrastructure (OCI) provider to manage OKE resources, and the Kubernetes provider to deploy the Bitwarden Helm chart.

    Here’s a high-level overview of the steps we’ll follow in the program:

    1. Set up OKE Cluster: We’ll define an OKE cluster using oci.ContainerEngine.Cluster resource. This is where our Bitwarden service will run.
    2. Configure Helm: We will set up Helm to deploy Bitwarden. For this, we use the kubernetes.helm.v3.Chart resource, which allows us to deploy Helm charts in a Kubernetes cluster.
    3. Deploy Bitwarden Helm Chart: Using the Helm Chart resource, we will specify the Bitwarden Helm chart to be deployed on our Kubernetes cluster.

    Let's go through the detailed program that performs these steps.

    import * as pulumi from '@pulumi/pulumi'; import * as oci from '@pulumi/oci'; import * as kubernetes from '@pulumi/kubernetes'; // Create the Oracle Cloud Infrastructure provider configuration const provider = new oci.Provider('oci', { region: 'us-phoenix-1', // Change to your OCI region }); // Define an Oracle Container Engine for Kubernetes (OKE) cluster const cluster = new oci.ContainerEngine.Cluster('bitwarden-cluster', { // Required configuration for the OKE cluster compartmentId: oci.config.compartmentId, vcnId: 'your-vcn-id', // Replace with your VCN ID where the cluster should be provisioned kubernetesVersion: 'v1.20.8', // Specify the desired Kubernetes version options: { // Optional configurations, set according to needs kubernetesNetworkConfig: { podsCidr: '', servicesCidr: '', }, serviceLbConfig: { subnetIds: ['your-subnet-id'], // Replace with the subnet IDs }, // Additional options can be set as required. }, }, { provider }); // Generate kubeconfig for OKE cluster const kubeconfig = pulumi.all([cluster.name, oci.config.compartmentId]).apply(([clusterName, compartmentId]) => oci.containerengine.getClusterKubeconfig({ name: clusterName, compartmentId: compartmentId, }, { async: true })); // Create a Kubernetes provider instance using the kubeconfig const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: kubeconfig.rawConfig, }); // Define the Helm chart resource for Bitwarden const bitwardenChart = new kubernetes.helm.v3.Chart('bitwarden', { chart: 'bitwarden', version: '2.1.1', // Specify the chart version you want to deploy fetchOpts: { repo: 'https://charts.bitwarden.net/', // The Helm repository URL }, }, { provider: k8sProvider }); // Export the cluster name and kubeconfig export const clusterName = cluster.name; export const kubeconfigContent = kubeconfig.rawConfig;

    In the preceding code:

    • We create an instance of the OKE cluster by defining oci.ContainerEngine.Cluster with the necessary configurations.
    • We obtain the kubeconfig file for the OKE cluster, which is required to interact with the cluster via the Kubernetes API.
    • We create a Kubernetes provider instance using the kubeconfig. This provider instance is used to create and manage Kubernetes resources.
    • We then define the Helm chart resource using kubernetes.helm.v3.Chart to deploy the Bitwarden chart. We specify the version and Helm repository URL for Bitwarden.
    • Lastly, we export the cluster name and the kubeconfig content, which can be used to access the cluster with kubectl or other Kubernetes tooling.

    To run the program:

    1. Ensure you have Pulumi installed and configured with your OCI credentials.
    2. Replace placeholders (e.g., 'your-vcn-id') in the code with actual values from your OCI setup.
    3. Run pulumi up to provision the resources and deploy the Bitwarden Helm chart.

    Note that you will need to provide the correct OCI compartment ID and the VCN ID along with any other necessary configurations tailored to your environment. This Pulumi program sets up a fully functional OKE cluster and deploys Bitwarden, ready for use. After deployment, you can configure Bitwarden further according to your needs.
