1. Deploy the gitlab-backup helm chart on AWS EKS


    To deploy the GitLab backup Helm chart on an Amazon EKS (Elastic Kubernetes Service) cluster using Pulumi, you'll need to set up a few things:

    1. EKS Cluster: A Kubernetes cluster managed by AWS EKS service.
    2. Helm Chart: Helm is a package manager for Kubernetes, and charts are packages of pre-configured Kubernetes resources.

    Steps to accomplish this task:

    • Define an EKS Cluster where your Helm chart will be deployed.
    • Create or use an existing IAM role for the EKS cluster to interact with other AWS services.
    • Deploy the GitLab backup Helm chart using the kubernetes.helm.v3.Chart resource in Pulumi.

    Here is a detailed program written in TypeScript that demonstrates how to deploy the GitLab backup Helm chart on an EKS cluster. The program uses Pulumi's AWS provider to create an EKS cluster and the Kubernetes provider to deploy a chart:

    import * as eks from '@pulumi/eks'; import * as aws from '@pulumi/aws'; import * as k8s from '@pulumi/kubernetes'; // Create an EKS cluster with the default configuration const cluster = new eks.Cluster('my-gitlab-cluster', {}); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider instance that uses the EKS cluster's kubeconfig const k8sProvider = new k8s.Provider('my-k8s-provider', { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the gitlab-backup Helm chart to the EKS cluster const gitlabBackupChart = new k8s.helm.v3.Chart('gitlab-backup', { // Specify the chart repository and chart name repo: 'gitlab', chart: 'gitlab-backup', // Specify chart values values: { // Specify the necessary values for the chart // For example, you might need to specify persistent volume claims or other configurations. // Check the Helm chart's values.yaml file or documentation for what values are needed. }, // Associate the Helm chart with the EKS cluster's Kubernetes provider }, { provider: k8sProvider } ); // Export the base URL for the GitLab instance export const gitlabBaseUrl = 'http://example.com'; // replace with your actual GitLab instance URL


    • The eks.Cluster creates an EKS cluster named 'my-gitlab-cluster.' The default configuration will provide you with a fully functioning EKS cluster. The eks.Cluster Pulumi resource abstracts a lot of the complexity of creating an EKS cluster.

    • kubeconfig is exported to allow interaction with the cluster using Kubernetes-standard commands like kubectl. This step is crucial for managing the EKS cluster and deploying applications.

    • The k8s.Provider resource is responsible for instantiating a Kubernetes provider that will interact with the EKS cluster we just created. It uses the kubeconfig obtained from the cluster creation process.

    • We then define the GitLab backup Helm chart deployment using k8s.helm.v3.Chart. We specify the repository and chart name corresponding to the GitLab backup Helm chart. You may need to adjust the repo and chart values as well as specify the necessary values based on the Helm chart's configuration options. Make sure to replace placeholders with actual URLs or relevant configuration details where necessary.

    • Finally, we export a dummy gitlabBaseUrl for completeness. In a real-world scenario, you'd replace this with the URL where the deployed GitLab instance is accessible.

    Next Steps:

    • After deploying, you'll likely need to configure your GitLab backup solution further, such as setting up backup schedules, storage destinations, etc.
    • Consult the official documentation of the GitLab backup Helm chart for more configuration options and best practices.
    • Ensure that your EKS cluster nodes have the necessary permissions and resources to run the backup jobs effectively. This might include IAM policies, security groups, and persistent volumes for storage.

    To run this program, ensure you have Pulumi CLI installed, set up your AWS access credentials, and run pulumi up in your terminal. This will start the deployment process where Pulumi will build the resources described in the program.
