1. Deploy the mev-boost helm chart on Linode Kubernetes Engine


    Deploying a Helm Chart on a Kubernetes cluster involves several steps:

    1. Set up a Kubernetes Cluster: This would involve provisioning a Kubernetes cluster with your cloud provider—in this case, Linode Kubernetes Engine (LKE).

    2. Install Helm: Helm is a package manager for Kubernetes which allows users to easily deploy applications using a pre-defined chart, which is a bundle of necessary resources and configurations.

    3. Configure kubectl: Ensuring your local kubectl is configured to communicate with your Kubernetes cluster.

    4. Add Helm repository: Helm charts are often stored in repositories. You'll need to add the repository which contains the mev-boost chart.

    5. Deploy the Chart: Once you have access to the chart through the repository, you can deploy it to your Kubernetes cluster using Helm commands.

    6. Verify the deployment: After the deployment, you'll want to check the status of your Helm release and ensure that the application is running correctly.

    The Pulumi toolset can be used to automate the provisioning of the Linode Kubernetes Engine cluster and the deployment of the mev-boost Helm chart. Below is a Pulumi program written in TypeScript that sets up an LKE cluster and deploys the mev-boost Helm chart to it.

    This program will do the following:

    • Provision a Linode Kubernetes Engine cluster using Pulumi's Linode provider.
    • Use Pulumi's Kubernetes provider to install the mev-boost Helm chart on the LKE cluster.

    Before running this program, you should have Pulumi installed and configured on your machine, a Linode account, and the necessary APIs enabled and authenticated.

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a Linode Kubernetes Engine (LKE) cluster const cluster = new linode.LkeCluster("mev-boost-cluster", { // Parameters for the cluster, such as region and Kubernetes version, go here. // These values are placeholders and should be replaced with appropriate ones. region: "us-central", k8sVersion: "1.20", label: "mev-boost-cluster", nodePools: [{ count: 2, // Number of nodes to deploy in the node pool type: "g6-standard-2", // Type of nodes used in the node pool }], }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeconfig; // A Kubernetes provider instance is created using the kubeconfig // from the newly created Linode Kubernetes cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Add the repository which contains the mev-boost Helm chart // Replace the 'repositoryURL' with the actual URL of the mev-boost Helm chart repository const repo = "https://repository.url"; // Deploy the mev-boost Helm chart const mevBoostChart = new k8s.helm.v3.Chart("mev-boost", { chart: "mev-boost", version: "chartVersion", // Specify the version of the chart fetchOpts: { repo: repo, }, }, { provider: k8sProvider }); // Export the name of the chart deployment export const mevBoostChartName = mevBoostChart.metadata.name;

    To run the above program:

    1. Save the code to a file with a .ts extension, for example, deploy-mev-boost.ts.
    2. Run pulumi up from the command line in the same directory as your file. Pulumi will perform the deployment as defined in the code.
    3. To check the status of your Kubernetes resources, use kubectl command-line tools with the exported kubeconfig.

    Please ensure that the repositoryURL and chartVersion are updated with the actual values for the mev-boost Helm chart repository and its version.

    Remember, managing infrastructure as code using Pulumi can involve costs pertaining to the cloud resources provisioned. Make sure to clean up resources after use if they are no longer needed to avoid unnecessary charges. Use pulumi destroy to tear down all resources managed by the Pulumi program.
