Purpose

I want ansible to provision virtual box vm's on my windows 8 machine [via Vagrant]. Everything needs to run locally and since Ansible doesn't run on Windows, I bootstrap a debian vm with ansible as the control machine. This code served as an example. After struggling with the system I got it somewhat working, but not completely (although ansible doesn't tell me).

Question

What configuration is required for a multi-machine setup using ansible [in a vm], vagrant and virtualbox [on windows host] if we want:

ssh acces from the host machine to the ansible-vm as well as all the slaves
ssh acces from the ansible-vm to all the slaves
being able to shield the multi-machine network from the host's network, if possible

Problem

Running ansible -m ping -all -i path-to-hosts yields ssh errors. It seems ansible tries to reach the machines named web1 and db1, but can't find such hosts.

回答1:

To answer my own question: the problem was resolved by upgrading ansible and importing the ssh keys of the other machines in Provision.sh.

# fix permissions on private key file
chmod 600 /home/vagrant/.ssh/id_rsa

# add web/database hosts to known_hosts (IP is defined in Vagrantfile)
ssh-keyscan -H 192.168.51.4 >> /home/vagrant/.ssh/known_hosts
ssh-keyscan -H 192.168.52.4 >> /home/vagrant/.ssh/known_hosts
chown vagrant:vagrant /home/vagrant/.ssh/known_hosts

# reload ssh in order to load the known hosts
/etc/init.d/ssh reload

回答2:

Thats a really long question problem. Ansible cant figure out the dns "ssh: Could not resolve hostname web1: Name or service not known"

Option 1

I like to simplify i boot my vagrant vm with static ip vm.network :private_network, ip: "xxx.xxx.xxx.xxx" and i edit my ansible host file

provsioning/hosts/dev_hosts

[webservers]
web1     ansible_ssh_host=xxx.xxx.xxx.xxx

[dbservers]
db1     ansible_ssh_host=xxx.xxx.xxx.yyy

Option 2

Use DNS or hostsfile

Hope that helps

Using "normal" Ansible modules to manage Windows boxes isn´t possible. Instead you have to use one of the windows modules. That´s the same for ping. It tries to connect via SSH to the Windows box, which doesn´t work.

Like skinnedknuckles already said, Ansible uses native Powershell remoting (and WinRM) instead of SSH to communicate with a Windows machine. So the win_ping module is the right way to do a ping with Ansible onto a Windows box:

ansible -m win_ping -all -i path-to-hosts

I assume you prepared your Windows 8 VM, like the docs are describing!?! If not, there´s this blog post explaining how to do all the steps incl. Vagrant setup with winrm connectivity in quite compact form.
