1. Deploy the sipp helm chart on Digital Ocean Kubernetes Service


    To deploy the SIPp Helm chart on the DigitalOcean Kubernetes Service (DOKS), you'll need to accomplish the following steps:

    1. Create a Kubernetes cluster: Set up a DOKS cluster where your Helm chart will be deployed.
    2. Install the Helm chart: Use Pulumi's Kubernetes provider to deploy the SIPp Helm chart to the cluster.

    Firstly, make sure you have the following prerequisites:

    • A Pulumi account with the CLI installed and set up.
    • DigitalOcean access token with necessary permissions to create resources.
    • Helm and kubectl installed locally, though Pulumi can manage Helm charts without them.

    Let's begin with the Pulumi code in TypeScript:

    import * as digitalocean from "@pulumi/digitalocean"; import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC1, // Choose the region that is closest to you version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default", size: digitalocean.DropletSlugs.DOKS_2vCPU_4GB, // Choose the droplet size as per your requirement nodeCount: 2, // Number of nodes in the node pool }, }); // Step 2: Use the cluster to create a Kubernetes provider const k8sProvider = new kubernetes.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the SIPp Helm chart using the Kubernetes provider const sippChart = new kubernetes.helm.v3.Chart("sipp", { chart: "sipp", // Specify the Helm repository here if SIPp Helm chart is hosted on a specific Helm repo // e.g., `repo: "https://helm.example.com/",` // version: "x.y.z", // Specify the chart version if necessary values: { // Provide any custom values file here if needed // service: { // type: "NodePort", // }, }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Export the public IP to access the SIPp application // The service type must be LoadBalancer to get a public IP, ensure that your Helm chart deploys a service with type LoadBalancer // export const sippPublicIp = sippChart.getResourceProperty("v1/Service", "sipp-service", "status").apply(status => status.loadBalancer.ingress[0].ip);

    This sample Pulumi program does the following:

    • It declares a DOKS cluster in the specified region with the desired version and node pool configuration.
    • Thereafter, a Pulumi Kubernetes provider is instantiated, using the kubeconfig of the newly created DOKS cluster.
    • Finally, the SIPp Helm chart is deployed using this Kubernetes provider. You'll need to replace placeholder comments with actual values relevant to your chart, including any custom configurations through the values argument.

    Please note that we commented out the export for sippPublicIp as it assumes SIPp service is of type LoadBalancer. If your SIPp Helm chart includes a service with type LoadBalancer, then uncomment and adapt accordingly to expose the application.

    Also, keep in mind the actual name of the Helm chart and necessary configurations for SIPp might differ based on the repository hosting the chart.

    Make any necessary adjustments to the program to cater to your specific SIPp Helm chart values and configurations before running it.

    To apply this Pulumi program:

    1. Save the above code to a file called index.ts.
    2. Run pulumi up in the directory containing the file to create the resources. Confirm the preview looks correct, and then select "yes" to perform the deployment.

    This will create a Kubernetes cluster in DigitalOcean, configure Pulumi to use it, and deploy your Helm chart all in one go!

    Remember, Helm charts are versioned, so it's a good practice to specify a version for stability. If you have a values.yaml file that you want to use to configure the Helm chart, you can point to it with a file path or embed the content directly in the values property.
