1. Deploy the rabbitmq-ha helm chart on Azure Kubernetes Service (AKS)


    To deploy the RabbitMQ HA Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, we will follow these steps:

    1. Set up an AKS cluster if you haven't already done so.
    2. Use the Pulumi kubernetes package to deploy RabbitMQ HA using the Helm chart.

    We will use the kubernetes.helm.v3.Chart resource which allows us to deploy a Helm chart within our Kubernetes cluster. Helm is a package manager for Kubernetes, and the HA (high-availability) version of RabbitMQ is a popular chart for setting up a RabbitMQ cluster with replication and failover configured.

    Below is a TypeScript program that uses Pulumi to deploy the RabbitMQ HA helm chart into an existing AKS cluster:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create a provider for the existing AKS cluster. const aksCluster = new k8s.Provider("aksProvider", { kubeconfig: "<Your AKS cluster kubeconfig>", }); // Deploy the RabbitMQ HA Helm chart using the kubernetes.helm.v3.Chart resource. const rabbitmqHelmChart = new k8s.helm.v3.Chart("rabbitmq-ha", { chart: "rabbitmq-ha", version: "1.39.4", // Specify the version of the chart you wish to deploy. fetchOpts: { repo: "https://kubernetes-charts.storage.googleapis.com/", }, // Values from the default Helm chart values may be overridden here. values: { replicaCount: 3, rabbitmqUsername: "admin", rabbitmqPassword: "password", // Consider using secrets for sensitive data. persistence: { enabled: true, storageClass: "default", size: "10Gi", }, }, }, { provider: aksCluster }); // Export the name of the chart deployment export const chartName = rabbitmqHelmChart.metadata.apply(metadata => metadata.name);

    Before running this code, be sure you have the following prerequisites met:

    • An existing AKS cluster
    • Pulumi CLI installed
    • Kubeconfig file for accessing your Kubernetes cluster
    • Knowledge of Helm and the RabbitMQ Helm chart values for customization

    In the example above, we are deploying the RabbitMQ HA Helm chart with some basic values. Keep in mind that you should secure your RabbitMQ setup, especially with respect to the credentials (rabbitmqUsername and rabbitmqPassword). In a production setting, use Pulumi's secret management instead of plain strings. You might also need to adjust the persistence settings or any other configurations depending on your specific requirements.

    Finally, run the following commands to deploy your infrastructure with Pulumi:

    pulumi up

    This will show you a preview of the changes and prompt you to confirm before applying them. Once confirmed, Pulumi will provision the specified resources in your cloud provider.
