1. Deploy the aws-rds-postgresql-database helm chart on Opensshift


    To deploy an AWS RDS PostgreSQL database using a Helm chart on OpenShift, you'll need to perform the following steps:

    1. Set up an OpenShift cluster where you have administrative privileges.
    2. Configure your local environment to interact with your OpenShift cluster using kubectl or oc.
    3. Ensure helm is installed on your local machine to manage Helm chart deployments.
    4. Install the RDS PostgreSQL Helm chart into your OpenShift cluster.

    Below is a Pulumi program that demonstrates how to use Pulumi with the Kubernetes provider to deploy a Helm chart for an AWS RDS PostgreSQL database in an OpenShift cluster. The program assumes that you have credentials configured for both AWS and your OpenShift cluster.

    Make sure that you have the necessary aws and kubernetes Pulumi packages installed in your project.

    Here is the program in TypeScript that you can use as a starting point:

    import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Replace these values with the correct ones for your OpenShift cluster and AWS RDS details. const config = new pulumi.Config(); const kubeconfig = config.requireSecret("kubeconfig"); // Your OpenShift kubeconfig const namespace = config.get("namespace") || "default"; // Target namespace for the Helm chart deployment // Create a provider for the OpenShift cluster. const openshiftProvider = new k8s.Provider("openshiftProvider", { kubeconfig: kubeconfig, }); // Define the Helm chart for the AWS RDS PostgreSQL instance. const postgresChart = new k8s.helm.v3.Chart("aws-rds-postgres", { repo: "bitnami", // The repository where the chart is located, replace with the correct one if different chart: "postgresql-ha", // Assuming the RDS PostgreSQL Helm chart is in this path; you may need to adjust this. namespace: namespace, // Specify the values for the Helm chart. values: { // Example: Replace with the actual values required for your AWS RDS PostgreSQL Helm chart postgresql: { replicaCount: 1, image: { registry: "docker.io", repository: "bitnami/postgresql", tag: "latest", }, }, // More AWS RDS PostgreSQL configuration here }, }, { provider: openshiftProvider }); export const postgresChartName = postgresChart.metadata.apply(meta => meta.name);

    The kubeconfig variable is a secret and should be set in your Pulumi configuration as such for security purposes.

    Before running this program with Pulumi CLI, replace the placeholder strings in the values object with the actual values required by the RDS PostgreSQL Helm chart you intend to deploy.

    The Chart resource in the program defines a new Helm chart installation using the specified Helm chart and values. We're setting up a new provider that points to the OpenShift cluster using its kubeconfig. This way, Pulumi knows where to deploy the Helm chart.

    Remember to install Pulumi and configure AWS and Kubernetes credentials before running the program. To deploy this to your OpenShift cluster, navigate to the directory containing this program and run:

    pulumi up

    This will initiate the deployment process where Pulumi will create a plan and ask for your confirmation before proceeding to apply the changes. If everything is configured properly, the AWS RDS PostgreSQL database service will be deployed on your OpenShift cluster using the specified Helm chart.
