1. Deploy the bitwarden helm chart on Google Kubernetes Engine (GKE)


    To deploy the Bitwarden Helm chart on Google Kubernetes Engine (GKE), you will need to perform the following steps:

    1. Create a new GKE cluster or use an existing one.
    2. Install and configure Helm on your local machine, if it is not already installed.
    3. Add the necessary Helm repository for Bitwarden.
    4. Create a Kubernetes namespace for Bitwarden if a specific one is desired.
    5. Install the Bitwarden Helm chart into the GKE cluster using Helm.

    The Pulumi program below goes through these steps programmatically. It uses Pulumi's GKE support and the Helm support in Pulumi's Kubernetes provider to stand up a new GKE cluster and install Bitwarden.

    Pulumi Program (TypeScript)

    Here's a complete Pulumi program that creates a GKE cluster and deploys the Bitwarden Helm chart onto that cluster. Comments in the code will guide you through what each section does:

    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a GKE cluster. const cluster = new gcp.container.Cluster("bitwarden-cluster", { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring", ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig to access your cluster export const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Step 2: Configure Kubernetes provider to use the created cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 3: Add the Bitwarden Helm chart repository and install the chart. const bitwardenNamespace = new k8s.core.v1.Namespace("bitwarden-ns", { metadata: { name: "bitwarden" } }, { provider: k8sProvider }); const bitwardenChart = new k8s.helm.v3.Chart("bitwarden", { chart: "bitwarden", version: "1.2.0", // Replace with the version of the chart you wish to deploy fetchOpts: { repo: "https://helm.bitnami.com/bitnami", // Bitwarden Helm repo }, namespace: bitwardenNamespace.metadata.name, }, { provider: k8sProvider }); // Export the Bitwarden Helm chart name export const bitwardenChartName = bitwardenChart.name;

    Make sure you have Pulumi and gcloud CLI installed and configured. To deploy this Pulumi program you would save the code to a file (e.g., index.ts), and then run pulumi up from the same directory. Pulumi CLI will orchestrate the deployment.

    Explanation of the Pulumi Program

    1. The program starts by importing dependencies for Pulumi, GCP, and the Kubernetes package.
    2. It defines a GKE cluster with a basic configuration, including the initial number of nodes, the version to use for the nodes and the master, and OAuth Scopes that allow nodes to interact with other GCP services.
    3. It exports the cluster name and kubeconfig. The kubeconfig will be used to interact with the cluster via kubectl or other Kubernetes tooling.
    4. A Kubernetes provider is instantiated using the kubeconfig, allowing Pulumi to communicate with our new GKE cluster.
    5. It creates a Kubernetes namespace for Bitwarden using the Pulumi Kubernetes provider.
    6. Finally, it installs the Bitwarden Helm chart from Bitnami's repository into our GKE cluster. It specifies the version of Bitwarden to install and the repository URL.

    Now you have Bitwarden deployed on a Google Kubernetes Engine cluster, managed by Pulumi!

    Note: While the Bitwarden chart version is hard-coded into the Pulumi program as 1.2.0, you would typically make this a configuration value that can be passed when invoking Pulumi. This way, you don't need to manually update the program each time you want to change the chart version.
