Deploy the hydra-maester helm chart on Azure Kubernetes Service (AKS)
TypeScriptTo deploy the "hydra-maester" Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, we will complete the following steps:
- Set up an AKS cluster using the
azure-native
provider. - Deploy the "hydra-maester" Helm chart to the cluster.
We're going to use the
azure-native
provider because it is a more finely grained, resource-level access to Azure services, andkubernetes
provider to deploy Helm chart to the AKS cluster.Below is a Pulumi program written in TypeScript that accomplishes these steps.
Detailed Explanation
Before we begin writing the code, make sure you have the Pulumi CLI installed and are logged in. You also need to be authenticated with Azure, which can typically be done via the Azure CLI with
az login
.First, we will create an AKS cluster. To do so, we will define an AKS cluster resource using Pulumi's
azure-native.containerservice.ManagedCluster
class.Once the AKS cluster is provisioned, we'll use Pulumi's
kubernetes
provider, particularly thehelm.v3.Chart
class, to deploy "hydra-maester" Helm chart. This class allows us to specify the chart name, default values for our configuration, and the chart repository where "hydra-maester" is located if it's not a part of the default Helm repository.Note that I'm assuming "hydra-maester" is a Helm chart available in a public repository; replace the repository URL "repo_url_here" with the actual URL of the chart's repository. Additionally, set up the appropriate values for your Helm release under
values
. If "hydra-maester" requires specific configurations, you'll need to include them in thevalues
object.Here's how the complete program looks:
import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an AKS cluster const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup"); const cluster = new azure.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, identity: { type: "SystemAssigned", }, agentPoolProfiles: [{ count: 1, vmSize: "Standard_DS2_v2", name: "agentpool", mode: "System", osType: "Linux", }], dnsPrefix: "myakscluster", }); const creds = pulumi.all([resourceGroup.name, cluster.name]).apply(([resourceGroupName, clusterName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: resourceGroupName, resourceName: clusterName, }); }); const kubeconfig = creds.kubeconfigs[0].value.apply(c => Buffer.from(c, "base64").toString()); // Step 2: Deploy the "hydra-maester" Helm chart to the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); const hydraMaesterChart = new k8s.helm.v3.Chart("hydraMaester", { chart: "hydra-maester", // Specify the repository URL if "hydra-maester" is not a part of the default helm repo fetchOpts: { repo: "repo_url_here", }, // Set the appropriate values for your chart deployment here values: { /* ... */ }, }, { provider: k8sProvider }); // Outputs export const aksClusterName = cluster.name; export const kubeconfigOutput = pulumi.secret(kubeconfig);
How to Run the Program
- Save the above code in a file named
index.ts
. - Ensure you have the
@pulumi/azure-native
and@pulumi/kubernetes
packages installed in your Node.js project:
npm install @pulumi/azure-native @pulumi/kubernetes
- Run
pulumi up
to preview and deploy the changes. Pulumi will automatically run this TypeScript program to provision the resources specified.
Remember to replace placeholder strings like "repo_url_here" with actual values for your particular scenario. The helm chart values should also be specified based on the needs of "hydra-maester". If it requires sensitive information like passwords, consider using Pulumi's secret for storing such values.
After running the Pulumi program, the AKS cluster should be up and running, and the "hydra-maester" Helm chart will be deployed to it.
