Manage Windows machines with Ansible (winrm)

Ansible is a very powerful automation tool that is developed from RedHat. Many large organizations rely on Ansible to automate tasks and procedures. In this article I will explain how one can use ansible to manage windows clients and servers.

In order to manage windows hosts ansible winrm plugin should be used to communicate with the client/server machine.

The first step is to verify that ansible is installed.

Alongside with ansible, on the control node the pywinrm module should be also installed. By default this one is not installed and one should do it manually.

The managed Windows client/server machines should be configured to allow remote connections. A very useful power shell script is already developed from other users and it needs only to be executed on the managed host.

If your execution policy is prohibiting this script to be executed, you should set-execution policy to RemoteSigned as shown below and then execute the powershell.

Control node should have network connectivity with the managed hosts.

Some environmental variables should be used, so that ansible knows how the connection will be performed (winrm). I included those variables in my inventory file as I created this lab just for demonstration. My inventory file looks like below:

Lastly make sure that the user that is used for the connection has administrative rights on the managed windows hosts. Otherwise some error codes will be returned.

Lastly confirm ansible on managed host is working by using win_ping module.
