1. Deploy the logrotate helm chart on AWS EKS


    To deploy the logrotate Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster using Pulumi, we will first need to set up the EKS cluster and then deploy the Helm chart to it. Pulumi supports a high-level eks package that simplifies the process of creating and managing EKS clusters.

    We will use the following Pulumi resources:

    1. eks.Cluster: This resource creates an EKS cluster. You can define the cluster's properties, such as its version, the subnets it should run in, and the instance type for the worker nodes.

    2. kubernetes.helm.v3.Chart: After the EKS cluster is up and running, we'll use the Helm chart resource to deploy the logrotate application onto the cluster. For this, we assume the chart is available in a Helm repository.

    Here's a brief program in TypeScript that sets up an EKS cluster and deploys the logrotate Helm chart to it:

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", {}); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Once the cluster is created, we can deploy applications to it, like the logrotate Helm chart. // Create a Kubernetes provider instance that uses our cluster from above. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Use the Helm Chart resource to deploy logrotate. const logrotateChart = new k8s.helm.v3.Chart("logrotate", { chart: "logrotate", // NOTE: You should specify the repository where the logrotate chart is hosted. // For this example, we use a placeholder URL. fetchOpts: { repo: "https://charts.example.com/", }, // Specify the version of the Helm chart you want to deploy. version: "1.0.0", }, { provider }); // Export the URL for the load balancer created by the Helm chart (if applicable). export const logrotateUrl = logrotateChart.getResourceProperty("v1/Service", "logrotate", "status") .apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);

    The example sets up an EKS cluster with default settings using eks.Cluster. It then defines a Helm chart deployment using kubernetes.helm.v3.Chart. logrotateChart represents the logrotate Helm chart; you'll need to replace "https://charts.example.com/" with the actual repository URL for the logrotate chart.

    Once the logrotate Helm chart is installed, if the service type is LoadBalancer, the external URL for the logrotate service is exported. You can access logrotate through this URL, assuming the chart exposes an external service.

    Please ensure you have Pulumi and the necessary AWS credentials installed and configured before running this program. With the Pulumi CLI, you can deploy this stack using the following commands:

    1. Create a new Pulumi project and stack.
    2. Place the TypeScript code into an index.ts file.
    3. Run pulumi up to review and deploy the changes.

    Remember to replace the Helm chart repository and version number with the actual ones for the logrotate Helm chart you wish to deploy. If you are using a private repository or need specific values in the Helm chart, you might have to modify the fetchOpts and add values properties accordingly.
