Workshop summary:

The Workshop is a lightweight introduction to Ansible for Windows deployments automation and configuration tasks. Things were simplified for the purpose of 2 hour workshop format. We will utilize Microsoft Azure resources (courtesy of Microsoft).

Prerequisites:

The Workshop is a hands-on experience and requires you to bring your own device.

You will need:

• Laptop (or other type of terminal with Internet access)
• Web browser
• ssh client
• RDP client

Prepare for the Workshop:

Register Microsoft Azure Pass with new Azure account and setup access privileges

For the purpose of the workshop we will utilize Azure Passes that enable free consumption of selected resources up to 100$ credit limit. You will be able to continue your journey into Ansible on Windows after the Workshop. Azure Passes can be consumed once per account so the safest way is to create a new Azure account. You will find detailed instruction below and a generic how to for reference.

Register new Azure account (takes ~ 2 minutes)

• Enter https://azure.microsoft.com/en-us/free/ and Start Free account.
• (Optional - if you already have another account) Use another account.
• Choose to create a new Azure account - Create one!.
• Apply for a new email address in @outlook.com domain by choosing - Get a new email address.
• Enter the username of your choice (should be relatively short).
• Set the password and confirm with 'Next'.
• Solve the captcha and confirm that you would like to stay signed in.
• STOP! Do not continue with account setup.

Redeem Azure Pass promo code (takes ~ 5 minutes)

• Enter https://www.microsoftazurepass.com/ and Start evaluation.
• Double check that your are using just created Azure account - Confirm Microsoft Account.
• Enter Azure Pass promo code provided by Instructor and hit Claim promo Code and then Activate.
• Fill in the forms, accept the policy (first checkbox) and confirm with Sign up.
• Wait for confirmation.
• Verify that the trial subscription was successfully added to your Azure account by checking Subscriptions in Azure Portal (Or get started with your Azure subscription).

Deploy Red Hat Enterprise Linux (RHEL) host with Ansible (takes ~ 1 minute)

Next step is to prepare our basic Ansible environment. You will deploy RHEL based VM with all necessary dependencies.

Just click Deploy to Azure button and provide additional information through Azure Portal form:

• Subscription: Azure Pass
• Resource group: Create new : ansiblerg
• Location: East US
• Admin Password: choose your password.

Check Agree to the terms and conditions stated above and confirm with Purchase.

Note: these resources will be covered with Free Azure Pass credits.

Create MS Azure app credentials and set required privileges

The following workshop exercises require us to provision Azure resources with Ansible modules. To enable Azure resource provisioning with Ansible we need to enable application access via Azure API. You will find detailed instructions below with a generic instructions for reference purposes.

Register the ansible application with Azure Active Directory (takes ~ 3 minutes)

• In Azure Portal enter Azure Active Directory / App registrations / New App Registration and fill in the form with:
  • name: ansible,
  • type: Web app / API,
  • url: http://ansible.net (or any URL).
• Hit Create.
• Write down application id (for future reference it will be azure_client_id).
• Enter Settings / Keys and fill in the first row with:
  • description: ansible,
  • expires: Never expires.
• Hit Save and write down key Value (for future reference it will be azure_secret)
• Enter Azure Active Directory / Properties and write down Directory ID (for future reference it will be azure_tenant)

Authorize the ansible application to manage resources (takes ~ 1 minute)

• Enter Subscriptions / Azure Pass and write down Subscription ID (for future reference it will be azure_subscription_id).
• Enter Access Control (IAM) / Add and fill in the form with:
  • Role: owner,
  • Assign access to: Azure AD user, group, or application,
  • Select: ansible,
• Click ansible and hit Save.

Your ansible application credentials will enable you to provision Azure resources with Ansible.

Verify written down "ansible" application credentials (takes ~ 1 minute)

Azure property name	Ansible module parameter	written down value
application id	azure_client_id
Key Value	azure_secret
Subscription ID	azure_subscription_id
Directory ID	azure_tenant

Verify that all resources are set correctly (takes ~ 2 minute)

The Azure deployment template should prepare a single RHEL virtual machine rhel7ansible and install the necessary tools.

You can check the VM in Azure Portal entering Virtual Machines and selecting rhel7ansible. Ssh access is available via public IP as ansible user with password of your choice. Azure template installs Python, Ansible with Windows modules and dependencies. It also clones this github repository.

Workshop Labs

Lab 01 Azure Resources Provisioning with Ansible

Ansible enables you to provision IaaS resources. This gives You an ability to automate Windows Server provisioning. Let's prepare a set of Windows VMs on Azure. We will use them for the rest of the workshop.

Lab 02 Installing software on Windows with Ansible and Chocolatey

You will install some software on your Windows VMs. We'll use Chocolatey package manager and download the software from public repository. Thanks to win_chocolatey Ansible module the operation is simple and the module handles all necessary prerequisites and dependencies for us.

Lab 03 Troubleshooting Ansible Windows modules

Let's go through some Windows specific module challenges that you may encounter during your adventure with Ansible in the Windows realm.

Lab 04 Create local Chocolatey repository

In most corporate environments we need to maintain internal repositories with software that we use for deployments. You will deploy local Chocolatey repository on workshop-w2 Windows VM and install Firefox on workshop-w1.

Lab 05 Explore idempotence

Idempotence is a term that describes a quality that enables us to run Ansible playbook consecutively and get the same predictable result every time.

There is usually more than one way to achieve desired results. Let's explore different approaches to deploying an IIS site and their consequences for idempotence.

After the Workshop

Stoping and starting Azure resources

You may wish to stop your Azure VMs to decrease the pace at which your credits are being depleted. Please inspect Azure Portal's Virtual Machines and check your options for stopping and starting the VMs.

Clean up

Remove deployed Azure resources

Go to lab01-azure_provisioning and run ./teardown.sh script.

In Azure Portal choose Resource Groups and remove the ansiblerg resource group.

Close Azure account

Please use the instructions from Cancel your subscription for Azure to close your Azure account.

Close outlook.com account

Please use the instructions from How to close your Microsoft account to close your Outlook.com account.
