Deploy the tmf-component helm chart on Azure Kubernetes Service (AKS)
TypeScriptTo deploy the
tmf-component
Helm chart on Azure Kubernetes Service (AKS), you'll need to go through several steps using Pulumi. These include setting up the necessary Azure infrastructure, configuring Kubernetes on AKS, and finally deploying the Helm chart.Below is a brief explanation of the process and the code you could use to deploy the
tmf-component
Helm chart:-
Creating an AKS Cluster: Before deploying the Helm chart, you need to have a Kubernetes cluster running on AKS. You'll create an AKS cluster using the
azure-native
provider, which allows you to declare the Azure resources in a Pulumi program. -
Configuring the Kubernetes Provider: To interact with the Kubernetes cluster and apply the Helm chart, you need to configure the Kubernetes provider. The provider will use the kubeconfig obtained from the AKS cluster setup.
-
Deploying the Helm Chart: Once you have the cluster and the Kubernetes provider set up, you can deploy the Helm chart to your AKS cluster.
-
Exporting Output: After the deployment, it's helpful to output the Kubernetes cluster name or other relevant information, which can be done using
export
in Pulumi.
Let's first install the necessary dependencies with npm:
npm install @pulumi/azure-native @pulumi/kubernetes @pulumi/pulumi
Now, here's the Pulumi TypeScript program that encapsulates these steps:
import * as azure from "@pulumi/azure-native"; import * as pulumi from "@pulumi/pulumi"; 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, agentPoolProfiles: [{ count: 3, // Example node count, adjust as needed vmSize: azure.containerservice.VMSizeTypes.Standard_DS2_v2, // Example size, adjust as needed mode: "System", name: "agentpool" }], dnsPrefix: "myakscluster", identity: { type: "SystemAssigned", } }); // Obtain the Kubeconfig after the cluster is created to configure the Kubernetes provider const creds = pulumi.all([cluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, })); const kubeconfig = creds.apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Step 2: Configure the Kubernetes provider const k8sProvider = new k8s.Provider("myK8sProvider", { kubeconfig: kubeconfig, }); // Step 3: Deploy the Helm Chart to AKS const tmfComponentChart = new k8s.helm.v3.Chart("tmf-component", { chart: "tmf-component", version: "1.0.0", // Example version, adjust as needed fetchOpts: { repo: "http://myhelmrepo.com/", // Example repository, adjust to where your chart is located }, }, { provider: k8sProvider }); // Step 4: Export the kubeconfig and cluster name export const aksClusterName = cluster.name; export const kubeConfigOutput = kubeconfig;
Explanation:
- We start by creating an Azure resource group to hold the AKS cluster using the
azure-native
provider. - Next, we create an AKS cluster within the resource group and define the size and number of nodes in the agent pool.
- Once the cluster is created, we get the credentials to generate the kubeconfig file, which is necessary for Pulumi to communicate with the AKS cluster.
- We instantiate the Kubernetes provider with the kubeconfig from the AKS cluster.
- Then, we deploy the
tmf-component
Helm chart using Pulumi’sk8s.helm.v3.Chart
class. - Finally, we export the cluster name and kubeconfig so you can access your cluster using
kubectl
or other Kubernetes tools.
Make sure to replace the placeholder values — such as the Helm chart version and repository URL(
http://myhelmrepo.com/
) — with the actual values for thetmf-component
chart.To run this Pulumi program, save it to a file (e.g.,
index.ts
), and execute the following commands:pulumi up
The
pulumi up
command will preview and deploy the changes described by the program. It will create an AKS cluster and deploy the specified Helm chart into it. After execution, you'll see the exported outputs, which you can use to interact with your AKS cluster.-
