1. Deploy the postgresql-backup-to-minio helm chart on Azure Kubernetes Service (AKS)


    To deploy the postgresql-backup-to-minio Helm chart on Azure Kubernetes Service (AKS), you need to follow these steps:

    1. Provision an AKS cluster: First, you need to provision an Azure Kubernetes Service cluster. You can do this by using the azure-native.containerservice.KubernetesCluster resource which will allow you to create a new AKS cluster in your Azure account.

    2. Integrate MinIO: You would typically run MinIO as a separate service, either within the same Kubernetes cluster or outside. If you need MinIO deployed within the cluster, you can do this using a Helm chart for MinIO as well or deploying it as a separate deployment.

    3. Deploy the PostgreSQL backup Helm chart: Finally, you can deploy the postgresql-backup-to-minio Helm chart. You will need to have Helm configured on your local system and added the chart's repository beforehand.

    The following example assumes that you have the Pulumi CLI installed and configured with your Azure account credentials. This program is in TypeScript and will use the Pulumi Azure Native and Kubernetes providers to deploy the resources.

    Before running this code, ensure to install the required packages by running:

    $ npm install @pulumi/azure-native @pulumi/kubernetes

    Here is a complete Pulumi program that you can use to deploy the postgresql-backup-to-minio Helm chart on an AKS cluster:

    import * as azure from "@pulumi/azure-native"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create a new resource group const resourceGroup = new azure.resources.ResourceGroup("my-resource-group"); // Create an AKS cluster const cluster = new azure.containerservice.KubernetesCluster("my-aks-cluster", { resourceGroupName: resourceGroup.name, managedClusterName: "myakscluster", identity: { type: "SystemAssigned" }, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: "mykube", enableRBAC: true, kubernetesVersion: "1.20.7", // For simplicity, we're using a public network profile. // Production workloads typically require a private cluster and network configuration. networkProfile: { networkPlugin: "kubenet", }, }); // Export the kubeconfig export const kubeconfig = cluster.kubeConfigRaw; // Create a Kubernetes provider instance that uses the kubeconfig from the AKS cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Write your MinIO deployment here if needed... // Deploy the PostgreSQL backup Helm chart using the k8s Provider const postgresBackupChart = new k8s.helm.v3.Chart("postgresql-backup", { chart: "postgresql-backup-to-minio", version: "<chart-version>", // Replace with the chart version fetchOpts: { repo: "https://charts.bitnami.com/bitnami", }, // You will need to specify the appropriate values for the chart here. values: { // Add your values for setting up the backup configuration here }, }, { provider: k8sProvider }); // Export the Chart name of the PostgreSQL backup export const postgresBackupChartName = postgresBackupChart.status.name;


    1. Resource Group: The azure.resources.ResourceGroup resource is used to create a new resource group in which all the resources like AKS will live.

    2. AKS Cluster: azure.containerservice.KubernetesCluster creates the AKS cluster. We've specified some properties like the number of nodes, VM size, and Kubernetes version. The kubeConfigRaw output is used to interact with the AKS cluster.

    3. Kubernetes Provider: Using the kubeconfig, we create an instance of the Pulumi Kubernetes provider. This allows us to deploy Kubernetes resources to the provisioned AKS cluster.

    4. MinIO Deployment: Before deploying the backup chart, you'd need a MinIO instance. This isn't included, as it's based on your specific configuration and setup. For a production setup, consider deploying MinIO with security and persistent storage configured.

    5. Helm Chart: We deploy the postgresql-backup-to-minio Helm chart using the k8s.helm.v3.Chart resource. The repo and version specify where to fetch the chart from and which version to use. The values field is where you would put the necessary values for configuring the backup setup. You'll need to fill this in with configuration that points to your MinIO instance, how often backups should run, and so forth.

    6. Chart Name: We export the Chart name, which can be useful for operations tasks like upgrades or rollbacks.

    After deploying this program, make sure to manage post-deployment activities and monitor your backups in the MinIO location you have configured. Always ensure that your Helm Chart, MinIO, and any sensitive data like passwords or access keys are handled securely and follow best practices when deploying to production environments.
