Azure Kubernetes Service (AKS) Cluster

View Code Deploy

Stands up an Azure Kubernetes Service (AKS) cluster and deploys an application to it.

Deploying the App

To deploy your infrastructure, follow the below steps.

Prerequisites

  1. Install Pulumi
  2. Configure Azure

Steps

  1. Create a new stack:

    $ pulumi stack init dev
  2. Login to Azure CLI (you will be prompted to do this during deployment if you forget this step):

    $ az login
  3. Set the azure location in which to run the test:

    $ pulumi config set azure:location westus
  4. Stand up the AKS cluster:

    Note: Due to an issue in Azure Terraform Provider, the creation of an Azure Service Principal, which is needed to create the Kubernetes cluster, is delayed and may not be available when the cluster is created. If you get a “Service Principal not found” error, as a work around, you should be able to run pulumi up again, at which time the Service Principal replication should have been completed. See this issue and this doc for further details.

    $ pulumi up
  5. After 10-15 minutes, your cluster will be ready, and the kubeconfig YAML you’ll use to connect to the cluster will be available as an output. You can save this kubeconfig to a file like so:

    $ pulumi stack output kubeconfig > kubeconfig.yaml

    Once you have this file in hand, you can interact with your new cluster as usual via kubectl:

    $ KUBECONFIG=./kubeconfig.yaml kubectl get nodes
  6. You can check that the application is loadbalanced across all of the pods:

    $ for i in {0..10}; do curl $(pulumi stack output url); done
  7. From there, feel free to experiment. Simply making edits and running pulumi up will incrementally update your stack.

  8. Once you’ve finished experimenting, tear down your stack’s resources by destroying and removing it:

    $ pulumi destroy --yes
    $ pulumi stack rm --yes
