Deploy the sipp helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

Deploying the SIPp Helm chart on Oracle Kubernetes Engine (OKE) is a task that involves setting up the Kubernetes environment within the Oracle Cloud Infrastructure (OCI) and then using the Helm package manager to deploy the SIPp application.

Here is a step-by-step guide and Pulumi program in TypeScript that demonstrates how to accomplish this:

Setting up the Kubernetes Cluster: We'll start by creating an Oracle Kubernetes Engine (OKE) cluster using the oci.ContainerEngine.Cluster resource. Make sure you have the right OCI configuration set up for authentication.
Deploying the SIPp Helm Chart: We will use the kubernetes.helm.v3.Chart from the Pulumi Kubernetes provider, which represents a Helm chart in a Kubernetes cluster.
Configuring the Helm Chart: Helm charts can be configured with values that dictate how the application should be set up in the cluster. These configurations will be passed to the values property.

Let's begin by writing the Pulumi program:

import * as pulumi from '@pulumi/pulumi';
import * as oci from '@pulumi/oci';
import * as k8s from '@pulumi/kubernetes';

// Step 1: Create an OKE cluster
const okeCluster = new oci.containerengine.Cluster("okeCluster", {
    // Define necessary details for the OKE cluster
    name: "my-oke-cluster",
    compartmentId: ociCompartmentId, // replace with your compartment ID
    kubernetesVersion: "v1.20.8",    // Provide a compatible Kubernetes version
    vcnId: ociVcnId,                 // replace with your VCN ID
    options: {
        serviceLbSubnetIds: [subnetId1, subnetId2], // replace with your subnet IDs
    },
    // ...and additional configuration as necessary.
});

// Step 1.1: Create a Node Pool for the cluster
const nodePool = new oci.containerengine.NodePool("nodePool", {
    clusterId: okeCluster.id,
    compartmentId: ociCompartmentId, // replace with your compartment ID
    nodeShape: "VM.Standard2.1",    // Node shape determines the amount of CPU and memory for each node
    // ...and additional configuration as necessary.
});

// Once the cluster is created, we need to configure kubectl and the Pulumi Kubernetes Provider to communicate with the cluster.
// Normally in an automated script, this would involve fetching the kubeconfig file from OCI and using it to create a Kubernetes provider instance.

// Fetch kubeconfig from OCI - This is typically a manual step
// Command: oci ce cluster create-kubeconfig --cluster-id <cluster-id> --file <kubeconfig-path> --region <region> --token-version 2.0.0

// Note: In this demonstration, we assume that you have set up the kubeconfig manually.

// Create a Kubernetes provider instance using the kubeconfig obtained from OCI
const provider = new k8s.Provider("okeK8s", {
    kubeconfig: '<kubeconfig-content>', // Your cluster kubeconfig content
});

// Step 2: Deploy the SIPp Helm Chart using Pulumi
const sippHelmChart = new k8s.helm.v3.Chart("sipp-helm-chart", {
    chart: "sipp",                // Provide the name of the Helm chart
    version: "1.0.0",             // Specify the version of the Helm chart
    fetchOpts: {
        repo: "https://example.com/helm-charts", // Provide the Helm chart repository URL
    },
    // Define any custom values required by the SIPp Helm chart
    values: {
        // Custom values for the SIPp Helm chart
    },
}, { provider });

// Step 3: Perform necessary exports
export const okeClusterName = okeCluster.name;
export const okeClusterEndpoint = okeCluster.endpoints.apply(endpoints => endpoints.publicEndpoint);

// Expose the SIPp Service endpoint if the Helm chart creates a Kubernetes Service of type LoadBalancer or NodePort.
// This is dependent on SIPp Helm chart specifics.

Please replace ociCompartmentId, ociVcnId, subnetId1, subnetId2 and other placeholder values with appropriate IDs from your OCI environment. Also, you need to provide your kubeconfig content or a way to obtain it, as well as any specific configurations you desire for your node pool or SIPp chart.

After these resources are defined in your Pulumi program, running pulumi up will initiate the process of creating your cluster and deploying your SIPp application on OCI. Make sure that the Helm chart for SIPp is available and that you point to the correct repository where the Helm chart is hosted.

Keep in mind to install Pulumi CLI and configure OCI credentials before running this program. The Pulumi CLI is used to deploy and manage infrastructure through code.OCI credentials are needed for the Pulumi CLI to authenticate with your Oracle Cloud Infrastructure account and create the resources.

Please note that the specifics of the Helm chart for SIPp could vary, and you would need to consult the documentation of that specific chart for what values are required or allowed.

Once applied, you can retrieve the OKE cluster endpoint and explore additional resources, like the cluster's node pool, using Pulumi's exported values.
