1. Deploy the gitlab-backup helm chart on Kubernetes

    TypeScript

    Deploying a Helm chart with Pulumi involves a few steps which include setting up a Kubernetes cluster context (if not existing), and then utilizing the Helm package to deploy the chart to the cluster.

    The following Pulumi TypeScript program demonstrates how to deploy a Helm chart, specifically the gitlab-backup chart. It assumes that you have a Kubernetes cluster running and that you have kubectl configured to connect to your cluster. Additionally, it presumes that the Helm chart you want to deploy is available in a Helm repository.

    In this program, we are using the Chart resource from the Pulumi Kubernetes package. This resource represents a single Helm chart that can be deployed to a Kubernetes cluster. Its properties include parameters like chart (name of the Helm chart), version (the version of the chart you want to deploy), and values (any custom values you want to pass to the chart).

    Here's how you can use Pulumi to deploy a Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // The Chart resource allows us to install a Helm chart from any source. // You can point to the chart either via a local path, a repository URL, or just the chart name with repository options. const gitlabBackupChart = new k8s.helm.v3.Chart("gitlab-backup", { // Replace with the correct repository URL or alias that contains the 'gitlab-backup' chart. repo: "gitlab", chart: "gitlab-backup", // Specify the version of the chart you want to deploy, or leave it out to deploy the latest version. version: "1.2.3", // Custom values for the GitLab backup Helm chart. values: { // These values will be specific to the 'gitlab-backup' chart. You'll need to check the chart's documentation to find which values are required. // For example: backup: { cron: { schedule: "0 */12 * * *", // Run the backup every 12 hours. }, storage: { size: "10Gi", // Size of the storage used for backups. }, }, // ... add other custom configuration values as needed. }, // Optionally, specify the namespace to deploy into. Defaults to 'default' if not provided. namespace: "gitlab-backups", }); // Export the name of the chart, if you want to reference it from outside the program. export const chartName = gitlabBackupChart.metadata.apply(m => m.name);

    In this program:

    • We import the Pulumi Kubernetes package, which contains helpers for deploying resources to Kubernetes using Pulumi.
    • We create a new instance of the Chart class, which represents the Helm chart we are deploying.
    • In the Chart constructor, we specify the name of the Helm chart, the repository where it is stored, and optionally a chart version.
    • The values property is used to override default settings with custom values defined in your Helm chart. You need to review the specific Helm chart you are deploying to find out what values are necessary or configurable.
    • The namespace property allows you to specify the Kubernetes namespace where the Helm chart should be deployed. This is optional, and if not set, the Helm chart will be deployed in the "default" namespace.

    Please replace the placeholder values like repo, version, and especially within values with the actual information specific to the gitlab-backup Helm chart you want to install.

    To use this program:

    1. Install Pulumi: Follow Installing Pulumi.
    2. Set up a Kubernetes cluster and configure kubectl to connect to it.
    3. Create a new Pulumi project: pulumi new kubernetes-typescript.
    4. Replace the contents of index.ts in the new project with the code provided above.
    5. Run pulumi up to preview and deploy the changes.

    After successfully running the program with Pulumi, the specified gitlab-backup Helm chart will be deployed into your Kubernetes cluster. You can then check the resources created by Helm using kubectl get all -n gitlab-backups, if you used the namespace gitlab-backups like in the example.
