Deploy the hivemq-platform helm chart on Azure Kubernetes Service (AKS)
TypeScriptIn order to deploy the
hivemq-platform
Helm chart on Azure Kubernetes Service (AKS), you'll need to accomplish a few steps:-
Create an AKS cluster: This is the environment where your Kubernetes resources will live. You'll need to specify the version of Kubernetes you want to run, as well as node size and count.
-
Install the Helm chart: Helm is a package manager for Kubernetes that allows you to define, install, and upgrade even the most complex Kubernetes applications.
Here is a Pulumi program written in TypeScript that demonstrates how to create an AKS cluster and deploy a Helm chart to it:
import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure resource group const resourceGroup = new azure.core.ResourceGroup("resourceGroup", { location: "East US", }); // Create an AKS cluster const cluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, vmSize: "Standard_D2_v2", }], dnsPrefix: `${pulumi.getStack()}-kube`, // Ensure that the latest Kubernetes version is used kubernetesVersion: azure.containerservice.getLatestKubernetesVersion({ location: resourceGroup.location, }).then(version => version.latestVersion), // Default Node Pool settings including availability to use Virtual Machine Scale Sets and one node // This default node pool is named "agentpool" defaultNodePool: { name: "agentpool", nodeCount: 1, vmSize: "Standard_DS2_v2", enableAutoScaling: true, minCount: 1, maxCount: 3, }, identity: { type: "SystemAssigned", }, }); // Export the Kubeconfig const exportedKubeConfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, rgName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }). apply(creds => creds.kubeconfigs[0].value). apply(enc => Buffer.from(enc, 'base64').toString()); // Create a provider for the Kubernetes cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: exportedKubeConfig, }); // Deploy the hivemq-platform helm chart const hivemqChart = new k8s.helm.v3.Chart("hivemq-platform", { chart: "hivemq-platform", version: "4.7.0", // Replace with actual chart version fetchOpts: { repo: "https://www.hivemq.com/helm/", // Replace with the actual repo URL for hivemq helm charts }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeConfig = exportedKubeConfig;
Detailed Explanation
-
Resource Group: In Azure, a resource group is a container that holds related resources for an Azure solution. The
ResourceGroup
resource provides a way to deploy and manage a set of resources as a unit. -
AKS Cluster: This is a managed Kubernetes service that simplifies deploying, managing, and operating Kubernetes clusters in Azure. The
KubernetesCluster
resource specifies the details of your cluster, such as the node size and the count of nodes. -
Kubeconfig Export: After the AKS cluster is created, we need to retrieve the
kubeconfig
file that will allow us to interact with our Kubernetes cluster using tools likekubectl
or the Kubernetes client library. -
Kubernetes Provider: The
k8s.Provider
resource uses the exportedkubeconfig
to create a Pulumi Kubernetes provider that knows how to communicate with your AKS cluster. -
Helm Chart: Finally, we deploy the
hivemq-platform
Helm chart usingChart
resource from Pulumi's Kubernetes package. You may need to change theversion
andrepo
parameters to match the version of the chart you intend to deploy.
What Happens When You Run This Program
- Pulumi will reach out to Azure and create the resources defined in the program.
- It will create a Kubernetes cluster in AKS.
- The program will obtain the kubeconfig for the newly created AKS cluster.
- Using this kubeconfig, Pulumi will deploy the
hivemq-platform
Helm chart to your AKS cluster.
Once the Pulumi program is finished running, you'll have a running instance of
hivemq-platform
on your AKS cluster. You can use thekubectl
command-line tool to interact with your Kubernetes resources or any other compatible Kubernetes management tool.-
