1. Deploy the gitlab-backup helm chart on Azure Kubernetes Service (AKS)


    To deploy the GitLab backup Helm chart to an Azure Kubernetes Service (AKS) cluster using Pulumi, you'll need to follow several steps:

    1. Provision an AKS cluster.
    2. Install Helm and Tiller on your AKS cluster if not already available.
    3. Deploy the GitLab backup Helm chart to the AKS cluster.

    For step 1, we'll use the azure.containerservice.KubernetesCluster Pulumi resource to create an AKS cluster. This resource allows you to define an AKS cluster with specified properties such as node count, node size, and Kubernetes version.

    For step 2, Helm 3, the package manager for Kubernetes, does not require Tiller to be installed on the cluster. Therefore, you can skip the Tiller installation part if you're using Helm 3.

    For step 3, we'll use the Pulumi Kubernetes provider to apply a Helm chart to the AKS cluster. Make sure you have the Helm chart available for GitLab backup.

    Below is a TypeScript program using Pulumi to accomplish these tasks.

    First, install the necessary Pulumi and Kubernetes packages if you haven't already:

    npm install @pulumi/pulumi @pulumi/azure-native @pulumi/kubernetes

    Now, create a new Pulumi project and replace its index.ts content with the following:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an AKS cluster const cluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: "<YOUR_RESOURCE_GROUP_NAME>", // For other properties like location and cluster details, refer to the Azure Native documentation // https://www.pulumi.com/registry/packages/azure-native/api-docs/containerservice/kubernetescluster/ }); // Export the kubeconfig export const kubeconfig = cluster.kubeConfig; // Helm Chart for GitLab backup. Modify the chart name and version as needed. const gitlabBackupChart = new k8s.helm.v3.Chart("gitlab-backup", { chart: "gitlab-backup", version: "<CHART_VERSION>", fetchOpts: { repo: "https://charts.gitlab.io/", // Make sure this is the correct repository URL for the GitLab backup chart. }, // You should provide additional configuration parameters for the GitLab backup chart here. // For example, you might need to specify the GitLab instance URL, access tokens, and backup schedule. values: { gitlabUrl: "https://<your-gitlab-url>", accessToken: "<your-access-token>", // ... more chart values as needed } }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfig }) }); // When running `pulumi up`, the AKS cluster will be provisioned first. After the AKS cluster is up and running, // the GitLab backup Helm chart will be deployed to the cluster.

    Please replace <YOUR_RESOURCE_GROUP_NAME>, <CHART_VERSION>, <your-gitlab-url>, and <your-access-token> with appropriate values for your setup.

    This Pulumi program defines an AKS cluster and then uses a Chart resource from the @pulumi/kubernetes package to deploy the GitLab backup Helm chart to your cluster. The kubeConfig is exported so you can interact with your AKS cluster using the kubectl command-line tool.

    To run the above Pulumi program:

    1. Set up Azure credentials with Pulumi.
    2. Use the pulumi up command to provision the resources. This will create the AKS cluster and deploy the specified Helm chart.

    Keep in mind that managing secrets like GitLab access tokens within your Pulumi program should be done securely. Consider using Pulumi's secret management or Azure's Key Vault to handle sensitive data.

    Lastly, make sure you refer to the official documentation of the GitLab backup Helm chart to configure it correctly based on your specific backup requirements and GitLab setup.
