1. Deploy the haproxy-postgres helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the haproxy-postgres Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you need to set up a couple of resources. First, you'll need an OKE cluster where your Helm chart will be deployed. Once you have a Kubernetes cluster ready, you will use the Pulumi Kubernetes provider to deploy the Helm chart.

    Below is a TypeScript program that demonstrates how to perform these tasks using Pulumi. The following steps are carried out by the code:

    1. Set up an Oracle Kubernetes Engine (OKE) cluster using the oci.ContainerEngine.Cluster resource. For simplicity, we assume that the Virtual Cloud Network (VCN) and other dependencies are already in place and their identifiers are provided.
    2. Create a Kubernetes provider instance to interact with the OKE cluster.
    3. Use the kubernetes.helm.v3.Chart resource to deploy the haproxy-postgres Helm chart onto the OKE cluster.
    import * as pulumi from "@pulumi/pulumi"; import * as oci from "@pulumi/oci"; import * as k8s from "@pulumi/kubernetes"; // Configuration variables for the OKE cluster const name = "haproxy-postgres-oke-cluster"; const compartmentId = "<your-compartment-id>"; // Replace with your Compartment ID const vcnId = "<your-vcn-id>"; // Replace with your VCN ID const kubernetesVersion = "v1.20.11"; // Specify the desired Kubernetes version // Create an OKE cluster const cluster = new oci.containerengine.Cluster("cluster", { compartmentId: compartmentId, kubernetesVersion: kubernetesVersion, name: name, vcnId: vcnId, options: { serviceLbSubnetIds: ["<your-lb-subnet-id-1>", "<your-lb-subnet-id-2>"], // Replace with your Load Balancer Subnet IDs // Other options can be specified according to your need }, }); // Create a Kubernetes provider instance using the kubeconfig from the OKE cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the haproxy-postgres Helm chart on the OKE cluster const chart = new k8s.helm.v3.Chart("haproxy-postgres", { chart: "haproxy-postgres", version: "1.0.0", // Replace with the desired Helm chart version // Optionally customize the chart values values: { // Specify any values required for the haproxy-postgres chart }, fetchOpts: { repo: "https://<your-repo>", // Specify the chart's Helm repository URL }, }, { provider: k8sProvider }); // Export the cluster name and chart status export const clusterName = cluster.name; export const chartStatus = chart.status;

    In this program:

    • We create an OCI Kubernetes cluster with the oci.ContainerEngine.Cluster resource.
    • Then, we instantiate a Kubernetes provider to interact with the OKE cluster using its kubeconfig.
    • We use the kubernetes.helm.v3.Chart resource to deploy the haproxy-postgres chart. You will need to replace <your-repo> with the URL to the Helm repository that contains the haproxy-postgres chart, and specify the version you want to deploy.
    • The values object in the Helm chart resource is where you can provide any custom configurations necessary for the haproxy-postgres Helm chart. Replace the placeholders with actual values.
    • Replace the placeholder <your-compartment-id>, <your-vcn-id>, <your-lb-subnet-id-1>, and <your-lb-subnet-id-2> with your actual OCI identifiers.
    • The outputs at the end are used to export the name of the created OKE cluster and the status of the Helm chart, so you can verify that everything is set up correctly after running the Pulumi program.

    Before running the Pulumi program, make sure you have the correct OCI credentials and the Pulumi CLI installed and configured. You can then run the following commands to deploy your Kubernetes resources:

    pulumi stack init haproxy-postgres-on-oke pulumi up

    Remember to review the Pulumi plan output carefully before confirming the deployment, as the above commands will provision resources in your cloud account that may result in charges.
