1. Deploy the gitlab-backup helm chart on Digital Ocean Kubernetes Service


    To deploy the GitLab backup Helm chart on Digital Ocean Kubernetes Service (DOKS), you will first need to set up a Kubernetes cluster on Digital Ocean. After that, you will deploy the Helm chart to the cluster. Here's how to accomplish this using Pulumi with TypeScript.

    Step 1: Set up a Kubernetes cluster on Digital Ocean

    You use the digitalocean.KubernetesCluster resource from the Digital Ocean Pulumi provider to create a new Kubernetes cluster. The nodePool property specifies the details about the node pool within the cluster, including the size which refers to the type of Droplet, the number of nodes in the pool, and the name of the node pool.

    Step 2: Deploy the GitLab backup Helm chart

    Once you have the cluster, you will use the kubernetes.helm.v3.Chart resource from the Kubernetes Pulumi provider, which allows us to deploy a Helm chart to the Kubernetes cluster. If your GitLab backup Helm chart is stored in a custom repository, you need to specify the repo and chart properties accordingly.

    Here's the Pulumi TypeScript program for these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a Kubernetes cluster on Digital Ocean const cluster = new digitalocean.KubernetesCluster("gitlab-backup-cluster", { // Replace with the desired region and Kubernetes version. region: "nyc1", version: "latest", // Create a node pool with desired configuration. nodePool: { name: "gitlab-backup-pool", size: "s-2vcpu-2gb", // Droplet size: 2 vCPUs, 2GB RAM nodeCount: 2, // Number of nodes in the node pool } }); // Once the cluster is provisioned, configure Pulumi to use the new cluster. const kubeconfig = cluster.kubeConfigs[0].rawConfig; const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 2: Deploy the GitLab backup Helm chart to the cluster const gitlabBackupChart = new kubernetes.helm.v3.Chart("gitlab-backup", { // Specify the Helm chart repository and the chart name. // NOTE: You might need to update these values to point to the gitlab-backup Helm chart. // For example: If the chart is in Helm stable repository, then use `repo: "https://kubernetes-charts.storage.googleapis.com/"`. repo: "<Your Helm chart repository URL>", chart: "gitlab-backup", // Ensure the chart name matches that in the Helm repository // Configure the chart values as needed. values: { // Your specific GitLab backup chart values go here. // For example: persistence.size: "10Gi" }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the chart deployment status. export const kubeconfigOutput = cluster.kubeConfigs[0].rawConfig; export const deployedChart = gitlabBackupChart.status;

    This program will create a Kubernetes cluster and deploy the GitLab backup Helm chart to it. Make sure to replace "<Your Helm chart repository URL>" with the actual URL of the repository where the GitLab backup Helm chart can be found. Furthermore, adjust the values object to include any necessary configurations that the chart requires.

    Note that provisioning the cluster and deploying the chart will often take several minutes. You can watch the progress in the Pulumi CLI as the changes are being applied.

    After deployment, the Kubernetes cluster configuration (kubeconfig) is exported so you can use it with kubectl to interact with your cluster. The deployedChart variable will provide you with information on the status of the Helm chart deployment on the Kubernetes cluster.
