1. Deploy the pgdump-to-s3 helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the pgdump-to-s3 Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you'll need to perform a few steps:

    1. Set up your Pulumi project and write the code to deploy the Helm chart.
    2. Ensure that your OKE cluster is already configured and accessible with kubectl.
    3. Use the Pulumi's Kubernetes provider to deploy the Helm chart to your OKE cluster.

    The following Pulumi program in TypeScript will allow you to do this:

    • First, you need to install the necessary packages:
      • @pulumi/pulumi: The core Pulumi SDK.
      • @pulumi/oci: The Pulumi provider for Oracle Cloud Infrastructure (OCI).
      • @pulumi/kubernetes: The Pulumi provider to interact with Kubernetes.

    You can install them using npm or yarn:

    npm install @pulumi/pulumi @pulumi/oci @pulumi/kubernetes


    yarn add @pulumi/pulumi @pulumi/oci @pulumi/kubernetes
    • After installing the packages, write a Pulumi program like the one below:
    import * as pulumi from '@pulumi/pulumi'; import * as oci from '@pulumi/oci'; import * as k8s from '@pulumi/kubernetes'; // Initialize OCI provider with necessary configs // You would need to have appropriate credentials and configuration for the OCI provider const provider = new oci.Provider('oci-provider', { // Provide your OCI configuration details here: // region: 'us-ashburn-1', // tenancyOcid: '', // userOcid: '', // privateKey: '', // fingerprint: '', // compartmentOcid: '' }); // Here you should reference your existing OKE cluster const okeCluster = oci.containerengine.getCluster({ // You should provide your existing OKE cluster ID clusterId: 'YOUR_OKE_CLUSTER_ID', }, { provider }); // Assume the kubeconfig is available or can be constructed from other available sources const kubeconfig = okeCluster.kubeconfig; // Create a Kubernetes provider instance using the kubeconfig from the OKE cluster const k8sProvider = new k8s.Provider('oke-k8s-provider', { kubeconfig: kubeconfig, }); // Deploy the `pgdump-to-s3` Helm chart const pgdumpToS3Chart = new k8s.helm.v3.Chart('pgdump-to-s3', { // Replace with the correct repository and chart details chart: 'pgdump-to-s3', version: 'CHART_VERSION', // specify the version of chart fetchOpts: { // If the Helm chart is in a custom repository, provide repo URL // repo: 'https://charts.my-org.com/', }, // Provide appropriate values for the Helm chart values: { // These would be specific to the `pgdump-to-s3` chart you are deploying // database: { // host: 'db.example.com', // name: 'mydb', // }, // s3: { // bucket: 'my-s3-bucket', // accessKey: 'AKIAIOSFODNN7EXAMPLE', // secretKey: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY', // region: 'us-west-2', // }, }, }, { provider: k8sProvider }); // To access the Helm chart after deployment, you can export any relevant endpoint details export const chartName = pgdumpToS3Chart.metadata.name;

    This Pulumi program starts by importing the necessary Pulumi packages. It then initializes an OCI provider with the appropriate credentials and configurations. Make sure you fill in your details in the OCI provider configuration, such as the region, tenancy OCID, user OCID, etc.

    Next, the program grabs the kubeconfig from your OKE cluster. This config is used to set up a Kubernetes provider, which Pulumi uses to communicate with your Kubernetes cluster to deploy resources.

    The pgdump-to-s3 Helm chart is deployed using the k8s.helm.v3.Chart class. You have to specify the chart and version, along with any custom fetchOpts if your Helm chart is hosted in a custom repository. The values object should be populated with the configuration required by the pgdump-to-s3 chart, such as database credentials and S3 details.

    Finally, the program exports the name of the Helm chart as a stack output, which can be used for reference.

    Keep in mind that the above program assumes you have preconfigured your Pulumi CLI with OCI credentials and configured kubectl to communicate with the OKE cluster.

    You'll run this program by executing Pulumi commands pulumi up to deploy the changes and pulumi stack output chartName to retrieve the exported chart name. Make sure you validate the Helm chart name pgdump-to-s3 and include the correct version for the chart you want to deploy.
