1. Deploy the fluentd-papertrail helm chart on Digital Ocean Kubernetes Service


    To deploy the fluentd-papertrail Helm chart on the Digital Ocean Kubernetes Service (DOKS), you must first set up a Kubernetes cluster on DigitalOcean. After the cluster is in place, you can use Pulumi's Kubernetes provider to deploy the Helm chart.

    The process can be divided into two main steps:

    1. Create a Kubernetes Cluster: This involves provisioning infrastructure on DigitalOcean for your Kubernetes cluster.
    2. Deploy the Helm Chart: Once the cluster is up and running, you can deploy the fluentd-papertrail Helm chart to your DOKS.

    Let's begin by writing the Pulumi program in TypeScript that will carry out these steps. I'll walk you through each step with explanations.

    Below is the complete Pulumi TypeScript program to deploy fluentd-papertrail on DOKS:

    import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Step 1: Create a Kubernetes Cluster on DigitalOcean. const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: 'latest', // It's generally a good idea to specify a particular version. nodePool: { name: 'default', size: 's-2vcpu-2gb', // This is a basic node size. Adjust based on your needs. nodeCount: 2, // Start with 2 nodes. This can scale based on requirements. }, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Deploy the `fluentd-papertrail` Helm chart on the cluster. const helmChart = new kubernetes.helm.v3.Chart('fluentd-papertrail', { chart: 'fluentd-papertrail', version: '0.2.0', // Specify the version of the chart you wish to deploy. namespace: 'default', fetchOpts: { repo: 'https://your-repository-url', // Replace with the actual repository URL that contains your chart. }, values: { // Customize any values required for `fluentd-papertrail`. papertrail: { // Example configuration. Use Papertrail's endpoint and port for your account. // You'll need to create your Papertrail account and get these details from there. endpoint: 'logsX.papertrailapp.com', port: 'XXXXX', }, }, }, { provider: new kubernetes.Provider('k8s-provider', { kubeconfig }) }); // Export the Helm chart status url export const fluentdStatus = helmChart.status.url;


    • DigitalOcean Kubernetes Cluster: We are creating a new DOKS with two nodes using the digitalocean.KubernetesCluster class. You need to set the region and node specifications according to your requirements. The latest version is being used in this example, but in a real-world scenario, you would specify a fixed version of Kubernetes for stability.

    • Kubernetes Provider: Pulumi’s Kubernetes provider is used to interact with the Kubernetes cluster. We create an instance of this provider using the exported kubeconfig from the DigitalOcean cluster.

    • Helm Chart: We are deploying the fluentd-papertrail Helm chart using the kubernetes.helm.v3.Chart class from Pulumi. Replace 'https://your-repository-url' with the respective Helm chart repository URL for fluentd-papertrail. Customize the values to reflect your Papertrail configuration.

    • Exports: We export the kubeconfig for potential use with kubectl and other services to manage the Kubernetes cluster outside of Pulumi. We also export the Helm chart status URL for easy access.

    After writing and saving this code in a file (e.g., index.ts), you would run pulumi up to execute it. Make sure you have Pulumi installed and configured with access to DigitalOcean.

    Remember to adjust the program with actual repository URLs, chart versions, and Papertrail settings relevant to your account.
