1. Deploy the postgresql-backup-to-minio helm chart on Kubernetes


    To deploy the postgresql-backup-to-minio Helm chart on a Kubernetes cluster using Pulumi, we will leverage the kubernetes.helm.v3.Chart resource. This resource allows us to deploy Helm charts in a Kubernetes cluster by specifying the chart name, repository, version, and any necessary values required by the chart.

    Before you start writing the Pulumi program, ensure that you have the following prerequisites ready:

    1. Kubernetes Cluster: A running Kubernetes cluster where you intend to deploy the Helm chart. Make sure you have kubectl configured to communicate with this cluster.
    2. Helm Chart Information: Know the chart details such as name, repository URL, and the version if you want to deploy a specific one.
    3. Helm Configuration: Helm values that are required to customize the PostgreSQL backup to MinIO, such as credentials, locations, and schedules.
    4. Pulumi Setup: Have Pulumi installed and configured for TypeScript.

    In the Pulumi program below, we'll import the necessary packages, create a new Kubernetes provider, and deploy the Helm chart. We'll assume that you've already set up and authenticated to your Kubernetes cluster outside of the Pulumi program, as the default provider will use the kubeconfig file from your local machine to communicate with the Kubernetes cluster.

    import * as k8s from "@pulumi/kubernetes"; // Define the Helm chart release for the PostgreSQL backup to MinIO const postgresBackupToMinio = new k8s.helm.v3.Chart("postgresql-backup-to-minio", { // Specify the Chart name here, and make sure you have added the correct repository // that contains your desired chart using the `helm repo add` command. chart: "postgresql-backup-to-minio", // Replace with the actual repository URL where the chart is hosted. fetchOpts: { repo: "https://charts.example.com/minio", }, // Specify the namespace where you want the release to be deployed. namespace: "backup", // Specify the version of the chart you want to deploy, or remove this line to deploy the latest version. version: "1.2.3", // Include any required Helm values here. This is dependent on the chart's values.yaml file. values: { minio: { // You should replace these values with actual configuration details suitable for your environment. serverUrl: "http://minio-service.minio.svc.cluster.local:9000", accessKey: "minio-access-key", secretKey: "minio-secret-key", defaultBucket: { enabled: true, name: "postgresql-backups", policy: "public", } }, // Additional configuration for PostgreSQL backups could go here. }, }); // Export the resources created by the Helm chart, which could include the URL for MinIO dashboard, // access keys, or any other important data. The actual data to export would depend on the chart's outputs. export const backupEndpoint = postgresBackupToMinio.getResourceProperty("v1/Service", "minio-service", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    This program creates a Helm chart deployment using Pulumi's Kubernetes provider. You would need to replace the placeholder values with the actual configuration that the postgresql-backup-to-minio chart expects. Always refer to the chart's values.yaml file or its documentation for the proper values configuration. After running this program with Pulumi, it will initiate a Helm release on your Kubernetes cluster.

    To run the Pulumi program:

    1. Save the above code in a file named index.ts.
    2. Run pulumi up in the same directory where your index.ts file is located. Pulumi will then perform the deployment based on the code.

    Remember to check Pulumi's documentation on Helm charts for more details on using the Chart resource and other related configurations for your deployment needs.
