1. Deploy the dbmate helm chart on AWS EKS

    TypeScript

    To deploy the dbmate Helm chart on AWS EKS, you’ll need to create an EKS cluster and then deploy the chart to it using Pulumi's Kubernetes and EKS packages.

    Here are the high-level steps:

    1. Create an EKS cluster.
    2. Configure the Kubernetes provider to communicate with the EKS cluster.
    3. Deploy the dbmate Helm chart onto the EKS cluster.

    The following Pulumi TypeScript program accomplishes these steps:

    import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster const cluster = new eks.Cluster("my-cluster", { // Specify the desired Kubernetes version and other settings for the cluster here version: "1.21", instanceType: "t2.medium", desiredCapacity: 2, minSize: 1, maxSize: 3, }); // Export the clusters' kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider instance that uses our EKS cluster's kubeconfig const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the dbmate Helm chart const dbmateChart = new k8s.helm.v3.Chart("dbmate-chart", { chart: "dbmate", // You need to specify the correct repository that contains the dbmate chart fetchOpts: { repo: "https://<helm_chart_repository>", }, version: "1.0.0", // Specify the version of the Helm chart you wish to deploy // Include any custom values you want to set for the dbmate chart }, { provider }); // Export the URL for the dbmate deployment if applicable // This depends on the specifics of the dbmate Helm chart and what it exposes

    Explanation:

    • The eks.Cluster class from the @pulumi/eks package is used to create a new Amazon EKS cluster. You define the Kubernetes version, instance size, and scaling configurations for your worker nodes in the cluster. (EKS Cluster documentation)

    • A k8s.Provider is instantiated using the kubeconfig provided by the EKS cluster. This provider is what tells Pulumi how to communicate with your new EKS cluster. (Kubernetes Provider documentation)

    • The k8s.helm.v3.Chart class is then used to deploy the dbmate Helm chart. For this to work, you need to know the correct repository URL for the Helm chart. The version parameter specifies the chart version you want to deploy. You can pass additional settings through the values parameter if required. (Helm Chart documentation)

    Make sure to replace https://<helm_chart_repository> with the actual Helm chart repository URL that hosts the dbmate chart.

    The export statements make kubeconfig and other outputs available on the command line after deployment, which is useful for connecting to your cluster using kubectl.

    Assuming you already have Pulumi and AWS CLI configured, save the above code to a file with a .ts extension, and navigate to the directory containing this file on the command line. Run pulumi up to execute the code and set up the EKS cluster with the dbmate helm chart.
