1. Deploy the postgresql-imagestreams helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the postgresql-imagestreams Helm chart on the Oracle Kubernetes Engine (OKE), you'll need to have an OKE cluster up and running. With Pulumi, you can create and configure Kubernetes resources using familiar programming languages – in this case, TypeScript.

    Here's a step-by-step guide, followed by a Pulumi TypeScript program, which demonstrates how you can deploy the postgresql-imagestreams Helm chart onto an existing OKE cluster:

    1. Setting up the OKE cluster: Before you can deploy the Helm chart, ensure that you have an active Oracle Kubernetes Engine cluster. This program assumes that the cluster is already configured and available for deployment.

    2. Installing the Pulumi CLI: You must have Pulumi CLI installed on your local machine. The Pulumi CLI will interact with your cloud providers and manage resources.

    3. Configuring Oracle Cloud Infrastructure (OCI) provider: In your local setup, ensure that you've configured the Pulumi with Oracle credentials. You can typically set the credentials in the environment or via the Pulumi configuration command.

    4. Helm Chart deployment: With Pulumi's Kubernetes provider, you can deploy a Helm chart directly. The Pulumi program will interact with your Kubernetes cluster and apply the Helm chart.

    Now let's dive into the TypeScript program which will deploy the postgresql-imagestreams Helm chart to your OKE cluster:

    import * as k8s from "@pulumi/kubernetes"; // Ensure that you have configured your Oracle Cloud Infrastructure provider with the required // credentials before running this program. // Create a chart resource to deploy postgresql-imagestreams helm chart. const postgresqlImagestreams = new k8s.helm.v3.Chart("postgresql-imagestreams", { // Replace `repo` with the URL of the Helm repository containing the `postgresql-imagestreams` chart. // Replace `version` with the chart version you want to deploy. chart: "postgresql-imagestreams", version: "<chart-version>", namespace: "<target-namespace>", // Set the Kubernetes namespace where you want to deploy the chart. // As part of the Helm values, you may configure the necessary parameters for the postgresql chart. // This includes setting various configurations such as the number of replicas, resource constraints, // persistent volume claims, etc. Below is an example of setting the replicaCount. // Refer to the chart's values.yaml file for the complete list of configurable values. values: { replicaCount: 1, }, // If you need to fetch the chart from a private Helm repository, set the `fetchOpts` with the // necessary credentials. fetchOpts: { repo: "<helm-repository-url>", }, }, { // If your Kubernetes cluster resides in a provider that is different from where you are running Pulumi, // you must specify the provider here. Otherwise, you can omit this. // provider: oracleProvider, }); // Export the status URL, which can be used to check the status of the Helm release. // Note: Make sure to replace 'http' with 'https' if your Helm chart is accessible via HTTPS. export const postgreSqlStatusUrl = `http://<oke-cluster-endpoint>/status/${postgresqlImagestreams.status.namespace}/${postgresqlImagestreams.status.name}`;

    Replace placeholders like <chart-version>, <target-namespace>, <helm-repository-url>, and <oke-cluster-endpoint> according to your specific settings and the Helm chart details.

    This program defines a Helm chart resource called postgresqlImagestreams. It specifies the Helm chart to deploy (postgresql-imagestreams), along with options like the chart version, namespace, and values, which are settings that can be configured in the Helm chart.

    After you set up this program:

    • Run pulumi up to preview and deploy these changes. It will show an output of what resources will be created.
    • Confirm the deployment to proceed, and Pulumi will deploy the Helm chart to your OKE cluster.
    • Once the deployment is successful, Pulumi will provide an output of the postgreSqlStatusUrl, which you can use to visit and check the Postgres status.

    Remember to consult the documentation of the postgresql-imagestreams Helm chart to understand all the configurable settings and adapt the values object in the program to match your needs.
