Exercise - Deploy applications to Azure Kubernetes Service (AKS)

Objectives

This guided project consist of the following exercises:

  • Exercise 1: Provision Azure Container Registry (ACR) and Azure Kubernetes Service (AKS).
  • Exercise 2: Build a Linux and Windows container images and store them in Azure Container Registry.
  • Exercise 3: Deploy container images to Azure Kubernetes Service.
  • Exercise 4: Review the deployment and deprovision all resources.

In this exercise you provision Azure Container Registry and Azure Kubernetes Service resources.

Exercise 1: Provision Azure Container Registry (ACR) and Azure Kubernetes Service (AKS)

In this exercise, you will create an Azure Container registry and an AKS cluster.

Note: To complete this exercise you will need an Azure subscription. For any properties that are not specified, use the default value.

Task 1: Create an Azure Container registry

In this task, you will create an Azure Container registry

  1. From your computer, open a web browser window and navigate to the Azure portal at https://portal.azure.com.
  2. When prompted, sign in by using a user account that has the Owner role in the Azure subscription you will be using in this lab.
  3. Sign in to the Azure portal.
  4. In the Azure portal, in the Search text box, search for and select Container registries.

  5. On the Container registries page, select + Create and specify the following settings:

    Setting Value
    Subscription The name of the Azure subscription you will be using in this lab
    Resource Group The name of a new resource group acr-01-RG
    Registry name Any valid, globally unique name consisting of between 5 and 50 alphanumeric characters
    Location Any Azure region in which you can create an Azure Container registry and an AKS cluster
    Use availability zones Disabled
    Pricing plan Basic

  6. On the Container registries page, select Review + create and, on the Review + create tab, select Create.

    Note: Proceed to the next exercise without waiting for the provisioning of the Azure Container registry to complete.

Task 2: Create an Azure virtual network and an AKS cluster

In this task, you will create an Azure virtual network and deploy an AKS cluster including a Windows node pool into it.

Note: While you could create a virtual network when provisioning an AKS cluster, deploying AKS clusters into an existing virtual network requires some additional considerations that you should be familiar with.

  1. In the Azure portal, in the Search text box, search for and select Virtual networks.

  2. On the Virtual networks page, select + Create and then, on the Basics tab of the Create virtual network page, specify the following settings:

    Setting Value
    Subscription The name of the Azure subscription you selected in the first exercise of this lab
    Resource Group The name of a new resource group aks-01-RG
    Virtual network name vnet-01
    Region The same Azure region you selected in the first exercise of this lab
  3. On the Basics tab of the Create virtual network page, select Next.
  4. On the Security tab of the Create virtual network page, accept the default settings and select Next.

  5. On the IP addresses tab of the Create virtual network page, ensure that the IP address space is set to 10.0.0.0/16, delete the default subnet, select Review + create and, on the Review + create tab, select Create.

    Note: Creating a virtual network should take only a few seconds, so you should be able to proceed directly to the next step.

  6. In the Azure portal, in the Search text box, search for and select Kubernetes services.

  7. On the Kubernetes services page, select + Create, in the dropdown list, select Create a Kubernetes cluster, and then, on the Basics tab of the Create Kubernetes cluster page, specify the following settings and then select Next:

    Setting Value
    Subscription The name of the Azure subscription you selected in the first exercise of this lab
    Resource Group aks-01-RG
    Cluster preset configuration Dev/Test
    Kubernetes cluster name aks-01
    Region The same Azure region you selected in the first exercise of this lab
    Availability zones None
    AKS pricing tier Free
    Kubernetes version Accept the default value
    Automatic upgrade Disabled
    Node security channel type None
    Authentication and Authorization Local accounts with Kubernetes RBAC

  8. On the Node pools tab of the Create Kubernetes cluster page, perform the following tasks:

    • In the Node pools section, select the agentpool link.
    • On the Update node pool page, in the Node size section, select the Choose a size link.
    • On the Select a VM size page, in the list of VM sizes, select D2s_v3 and then click Select.
    • Back on the Update node pool page, set Scale method to Manual and Node count to 2.
    • On the Update node pool page, select Update.

    Note: You might need to increase vCPU quotas or change the VM SKU to accommodate the node size and node count values. For information regarding the procedure to increase vCPU quotas, refer to the Microsoft Learn article Increase VM-family vCPU quotas.

    Note: You will add a Windows node pool to the cluster. This required changing the network configuration to Azure CNI from the default Kubenet. The Kubenet network configuration does not support Windows node pools.

  9. Back on the Node pools tab of the Create Kubernetes cluster page, select Next.
  10. On the Networking tab of the Create Kubernetes cluster page, ensure that the Azure CNI option is selected, select the Bring your own virtual network checkbox, in the Virtual network dropdown list, select vnet-01, and below the Cluster subnet textbox, select Manage subnet configuration.
  11. On the vnet-01 | Subnets page, select + Subnet.

  12. On the Add subnets page, specify the following settings and select Save:

    Setting Value
    Name aks-subnet
    Subnet address range 10.0.0.0/20
  13. Back on the vnet-01 | Subnets page, in the breadcrumb trail in the top-left part of the page, select Create Kubernetes cluster.

  14. Back on the Networking tab of the Create Kubernetes cluster page, specify the following settings:

    Setting Value
    Virtual network vnet-01
    Cluster subnet aks-subnet (10.0.0.0/20)
    Kubernetes service address range 172.16.0.0/22
    Kubernetes DNS service IP address 172.16.3.254
    DNS name prefix aks-01-dns
    Network policy None
  15. On the Networking tab of the Create Kubernetes cluster page, select Previous.
  16. Back on the Node pools tab of the Create Kubernetes cluster page, select + Add node pool.

  17. On the Add node pool page, specify the following settings:

    Setting Value
    Node pool name w1pool
    Mode User
    OS type Windows 2022
    Availability zone None
    Enable Azure spot instances Disabled
    Node size D2s_v3
    Scale method Manual
    Node count 2
    Max pods per node 30
    Enable public IP per node Disabled

    Note: Here as well you might need to increase vCPU quotas or change the VM SKU to accommodate the node size and node count values.

  18. On the Add node pool page, select Add.
  19. Back on the Node pools tab of the Create Kubernetes cluster page, select Next.
  20. On the Networking tab of the Create Kubernetes cluster page, select Next.
  21. On the Integration tab of the Create Kubernetes cluster page, in the Container registry dropdown list, select the entry representing the Azure Container registry you created in the previous exercise, ensure that Azure Policy option is disabled, and select Next.
  22. On the Monitoring tab of the Create Kubernetes cluster page, de-select the Enable Prometheus metrics checkbox, de-select the Enable recommended alert rules checkbox, and then select Review + create.

  23. On the Review + create tab of the Create Kubernetes cluster page, select Create.

    Note: Proceed to the next exercise without waiting for the provisioning of AKS cluster to complete. The provisioning process might take about 5 minutes.
