1. Deploy the amazon-ec2-metadata-mock helm chart on Kubernetes

    TypeScript

    To deploy the amazon-ec2-metadata-mock Helm chart on a Kubernetes cluster using Pulumi, you will need to use the @pulumi/kubernetes package. This package is used to interact with Kubernetes resources within a Pulumi program.

    The amazon-ec2-metadata-mock Helm chart is a tool from AWS which is used to simulate the EC2 metadata service. This can be particularly useful when you're running your applications on Kubernetes and need to emulate AWS EC2 metadata for testing or development purposes.

    Below you will find a Pulumi program that sets up the necessary steps to deploy this Helm chart to a Kubernetes cluster:

    1. Create a new Chart resource using the Pulumi Kubernetes provider. The Chart resource is a representation of a Helm chart, which is a package of pre-configured Kubernetes resources.
    2. When initializing the Chart resource, specify the chart name, version, and any custom values you want to pass into your Helm chart.

    Here's the TypeScript Pulumi program that performs the deployment:

    import * as k8s from "@pulumi/kubernetes"; // Define the amazon-ec2-metadata-mock Helm chart details. const chartName = "amazon-ec2-metadata-mock"; const chartVersion = "<VERSION>"; // Replace with the desired chart version const chartRepo = "https://aws.github.io/eks-charts/"; // Create an instance of the amazon-ec2-metadata-mock Helm chart in the default namespace. const metadataMockChart = new k8s.helm.v3.Chart("amazon-ec2-metadata-mock-chart", { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo, // Specify the repository where the chart is hosted. }, // In case you need to override chart values, specify them here. values: { // Provide any values you need to customize the behavior of the Helm chart. }, namespace: "default", // Optional: specify the namespace where you want to deploy the chart. }); // Export the name of the chart deployment. export const chartNameDeployment = metadataMockChart.metadata.apply(meta => meta.name);

    In the code above:

    • We import the @pulumi/kubernetes package to interact with Kubernetes in Pulumi.

    • We set the chartName, chartVersion, and chartRepo variables. Ensure you replace <VERSION> with the actual version number of the chart you wish to deploy.

    • We create a new Helm Chart resource named amazon-ec2-metadata-mock-chart that references the amazon-ec2-metadata-mock Helm chart from the provided repository.

    • We specify the values property in case you need to configure any specific settings for your Helm chart deployment. Helm charts come with default values, but they can be overridden based on your requirements.

    • The namespace property is optionally used to specify the Kubernetes namespace in which to deploy the resources. If not specified, the default namespace is used.

    • Finally, we use Pulumi's export statement to output the name of the deployment, which you can use to reference the deployment in your Kubernetes cluster after it has been created.

    Remember to replace <VERSION> with the actual chart version you want to deploy. To find available versions for the chart, you can browse the Helm chart repository or use Helm CLI commands like helm search repo.

    Before running this program, ensure you have:

    • Installed Pulumi CLI
    • Configured the Pulumi Kubernetes provider (i.e., you're authenticated with your Kubernetes cluster)
    • Installed the required node modules by running npm install in your Pulumi project directory

    To run this program, navigate to your Pulumi project directory and execute:

    pulumi up

    This will preview the changes and, upon confirmation, apply them to your cluster. The output will include the name of the deployment, which you can then use to verify the resources deployed in your Kubernetes cluster.
