I was following the guide on https://servercheck.in/blog/running-ansible-within-windows.

I may have misunderstood what was meant by "if you would like to use Ansible as a provisioner for Vagrant..." I thought that meant standing up a Vagrant guest OS. I was starting my own Vagrant guest, so I didn't think this applied to me. I thought the only hurdle I was running into was that the line endings were CRLF rather than just LF. I changed that in Git. I can SSH into the Vagrant guest, so I was surprised when running the playbook failed. Turning on verbose logging -vvvv the error looks different than what you were describing in the blog post:

$ ansible-playbook -vvvv <playbook.yml> -i host_inventories/hosts.yml --tags "" --private-key=/cygdrive/c/Users//.vagrant.d/insecure_private_key -u vagrant

This is one of the reasons I gave up on using Ansible provisioners in windows, and using this project (on GitHub) instead. See http://cygwin.com/ml/cygwin/2010-08/msg00088.html. Basically, Cygwin doesn't support the way Ansible does SSH. You may be able to work around this using a different connection method or something, but it's hard (if not impossible) to get Ansible working from within Windows/Cygwin.

It's better to create another VM with Vagrant, install Ansible on that, then use that VM to connect to and provision the original VM. Or you can use this script (JJG-Ansible-Windows) as a shell provisioner within Vagrant to launch Ansible from within your VM and run it through the shell (rather than directly within Cygwin/Windows).

@rbeesley @geerlingguy The reason you are having this issue is you have to use "power shell" not cygwin and you have to add this to your provision shell script.

pip install http://github.com/diyan/pywinrm/archive/master.zip#egg=pywinrm

This will install the tools needed to communicate properly

my error message:
$ ansible hp -m raw -a "hostname"
hp | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: mux_client_request_session: read from master failed: Connection reset by peer\r\nFailed to connect to new control master\r\n",
"unreachable": true
}

according to this: http://everythingshouldbevirtual.com/ansible-using-ansible-on-windows-via-cygwin ,It works.
This error above is from using Cygwin and can easily be solved by creating an ansible.cfg file in your playbook folder with the following.
nano ansible.cfg
....
[ssh_connection]
ssh_args = -o ControlMaster=no

Hi webloginwu, Your,

This error above is from using Cygwin and can easily be solved by creating an ansible.cfg file in your playbook folder with the following.

suggestion helped me to solve my problem. Thank you so much.

@Secrole6789 - Awesome! Glad that @webloginwu helped. Note that this particular project is no longer maintained, but I'm going to keep it up so people can continue to use it for reference.

I succeeded with alternative ssh connectivity option in inventory file:

all:
  hosts:
    lighttpd:
      ansible_host: 192.168.33.10
      ansible_port: 22
      ansible_user: root
      ansible_connection: paramiko

Although local ansible.cfg fixes connectivity too.

I don't understand why following inventory options are not passed to ssh:

  ansible_ssh_common_args: "-o ControlMaster=no"
  ansible_ssh_extra_args: "-o ControlMaster=no"

Another easy fix is adding env var:

export ANSIBLE_SSH_ARGS='-o ControlMaster=no'
