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


    To deploy the jh-gitlab Helm chart on AWS Elastic Kubernetes Service (EKS), you will need to perform several steps:

    1. Set up an EKS cluster where your applications will run.
    2. Configure your Kubernetes provider to connect to your EKS cluster.
    3. Use the Helm chart to deploy your application (jh-gitlab in this case) to your EKS cluster.

    Here's a high-level overview of the steps in the Pulumi program:

    • EKS Cluster: Without an existing cluster, you will create an EKS cluster by defining aws.eks.Cluster resource. This represents your Kubernetes cluster in AWS.
    • Kubernetes Provider: You will then create a Kubernetes provider to interact with the EKS cluster. This provider uses the output from the EKS cluster to connect to your Kubernetes cluster.
    • Helm Chart: With the Kubernetes provider in place, you will define a kubernetes.helm.v3.Chart resource to deploy the jh-gitlab chart from its respective Helm repository.

    Let's get into the detailed Pulumi program written in TypeScript that can accomplish this:

    import * as pulumi from '@pulumi/pulumi'; import * as aws from '@pulumi/aws'; import * as awsx from '@pulumi/awsx'; import * as eks from '@pulumi/eks'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create an EKS cluster. // Refer to https://www.pulumi.com/docs/reference/pkg/aws/eks/cluster/ const cluster = new eks.Cluster("my-eks-cluster", { // You can specify additional options here to customize your EKS cluster. // For instance, you might want to define the `instanceType` or `desiredCapacity` for its node group. }); // Step 2: Use the kubeconfig from the generated EKS cluster to create a Kubernetes provider instance. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Step 3: Deploy the jh-gitlab Helm chart onto the EKS cluster using the Kubernetes provider. // Refer to https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/ const gitlabChart = new k8s.helm.v3.Chart("jh-gitlab-chart", { chart: "jh-gitlab", // You need to specify the repository that contains the jh-gitlab helm chart. // For example: repo: "https://charts.gitlab.io/" // Include the version if you want to deploy a specific version of the Helm chart. // You can also provide `values` to customize the deployment. }, { provider: k8sProvider }); // Export the kubeconfig to access the cluster with kubectl. export const kubeconfig = cluster.kubeconfig;

    How to Use the Program:

    1. Save the above code in a file named index.ts.

    2. Install the necessary Pulumi packages if you haven't already, through npm or yarn.

      npm install @pulumi/pulumi @pulumi/aws @pulumi/awsx @pulumi/eks @pulumi/kubernetes
    3. Run pulumi up to preview and deploy the changes. Pulumi CLI will show you a preview of the resources that will be created. After reviewing, select "yes" to deploy the resources.

    4. Once deployed, Pulumi will output the kubeconfig needed to interact with your EKS cluster using kubectl.


    In this program:

    • You're creating an EKS cluster with a default configuration. Real-world usage might require more detailed setup, such as defining VPC, subnets, and security groups.
    • With the EKS cluster created, a Kubernetes provider is defined, which is needed for the Helm chart to interact with the cluster.
    • Finally, the jh-gitlab Helm chart is deployed to the cluster using the parameters specified.

    Make sure to replace stubbed values like the Helm chart repository with actual information corresponding to the jh-gitlab Helm chart.

    Keep in mind that you need AWS credentials configured, either through the AWS CLI or by setting environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, etc.), for Pulumi to deploy resources to your AWS account. Similarly, ensure you have Pulumi CLI installed and set up.
