1. Deploy the fluentd-kubernetes-aws helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the fluentd-kubernetes-aws Helm chart on Oracle Kubernetes Engine (OKE), you will use Pulumi's Kubernetes and OCI (Oracle Cloud Infrastructure) providers. The Kubernetes provider is used to deploy Helm charts, whereas the OCI provider is required to work with Oracle Cloud resources such as OKE.

    Here's the process:

    1. Set up and configure an Oracle Kubernetes Engine cluster using the oci.ContainerEngine.Cluster resource.
    2. Deploy the fluentd-kubernetes-aws Helm chart to the OKE cluster with the kubernetes.helm.v3.Chart resource.

    Below is a TypeScript program that demonstrates how to perform these steps. This Pulumi program assumes that you have set up Pulumi with the appropriate credentials for Oracle Cloud Infrastructure.

    import * as pulumi from "@pulumi/pulumi"; import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; // Create an Oracle Kubernetes Engine (OKE) cluster const okeCluster = new oci.containerengine.Cluster("myOkeCluster", { compartmentId: oci.config.compartmentId, // Your OCI compartment ID kubernetesVersion: "v1.21.5", // Specify your desired K8s version name: "fluentd-cluster", // Name your cluster vcnId: "<YOUR_VCN_ID>", // Specify your VCN ID options: { // Service and networking options // Add required options like serviceLbSubnetIds, kubernetesNetworkConfig, etc. } // Add other necessary properties like `kmsKeyId`, `endpointConfig`, etc. }); // Output the kubeconfig for the OCI OKE cluster const kubeconfig = pulumi.all([okeCluster.id]).apply(([clusterId]) => { return oci.containerengine.getClusterKubeconfig({ clusterId: clusterId, }); }); // Create a Kubernetes provider instance using the kubeconfig const k8sProvider = new k8s.Provider("okeK8sProvider", { kubeconfig: kubeconfig.rawConfig, }); // Deploy the fluentd-kubernetes-aws helm chart to the OKE cluster const fluentdHelmChart = new k8s.helm.v3.Chart("fluentd-chart", { chart: "fluentd-kubernetes-aws", values: { // Provide any specific configuration values here }, fetchOpts: { repo: "https://helm-repository/fluentd-helm-charts", // Replace with the actual Helm repo URL }, }, { provider: k8sProvider }); // Export the cluster name and kubeconfig export const clusterName = okeCluster.name; export const clusterKubeconfig = kubeconfig.rawConfig;

    In this program:

    • We first create an Oracle Kubernetes Engine cluster with the oci.ContainerEngine.Cluster resource. Be sure to replace "<YOUR_VCN_ID>" with your actual VCN ID and add any other required configurations like subnets, Kubernetes networking options, etc.
    • We then obtain the kubeconfig for the created OKE cluster using the oci.containerengine.getClusterKubeconfig function. This kubeconfig is used to communicate with your Kubernetes cluster.
    • With the kubeconfig, we set up a Pulumi Kubernetes provider, k8s.Provider, which is needed to deploy resources to the Kubernetes cluster.
    • Finally, we deploy the fluentd-kubernetes-aws Helm chart using the k8s.helm.v3.Chart resource. Make sure to provide the actual repository URL in fetchOpts where the Helm chart is located and any values you want to configure for the chart.

    Please replace placeholders and add the required configurations that match your specific OCI environment and your fluentd-kubernetes-aws Helm chart requirements.

    Since you're a novice, remember that Pulumi programs are written in familiar programming languages. You define desired state (like our Kubernetes cluster and Helm chart), and Pulumi understands how to create, update, and delete resources in the correct order with the correct dependencies.

    The Pulumi CLI performs the actual work of orchestrating the required changes upon running pulumi up. After you have written your Pulumi program and reviewed the execution plan, this CLI command will apply the changes to your cloud provider.
