[See part 1]({% post_url 2019-03-07-ansible-part-1 %})

Now we're gonna setup ansible to work with a git repository. The process is quite similar with `ansible-playbook` the only difference is that command will get a repository instead of a folder. Following the previews example we'll get vim setup automated.

Do create a git repository wherever you see fit ([gitlab](https://about.gitlab.com/) and [github](https://github.com/) offer free repositories). For this task we're gonna need to add only two file: one for the `yml` file describing the tasks and the `.vimrc` file.

In the `.vimrc` add your own configuration, you can see mine [over here](https://github.com/gabrielgio/homestation/blob/241b27285d8cba8548277f3508e097439831a6eb/config/.vimrc), it is pretty simple as I don't use it but for simple text editing (like this post) so you can start with it if you don't have one.

The `yml` file will have two tasks, one is to install vim itself, identical as it is in the part 1.

{% highlight yml %}
# main.yml
---
- name: install vim
  dnf:
    name: vim
    state: latest
{% endhighlight %}

The second task it to copy `.vimrc` file to your `$HOME`, for it we shall use [copy module](https://docs.ansible.com/ansible/latest/modules/copy_module.html):

{% highlight yml %}
---
- name: copy vimrc file
  copy:
    src: config/.vimrc
    dest: ~/
    mode: 0644
{% endhighlight %}

After adding those two files your repository will be something [like this](https://github.com/gabrielgio/homestation/tree/debcf3458df511aef9f7dca0cb73f6cf6baddd5d).

And now we just need to run `ansible-pull` command

{% highlight bash %}
#you may need run it as a sudo
ansible-pull -U <YOUR_REPO> -i all main.yml
{% endhighlight %} 

Params:
* `-i` is a list of hosts. 
* `-U` is the git repository url.

Remember `man` is your best friend take a look at `man ansible-pull` to know more about the params.

The best part if you want to test quickly you can just run my sample and see the result:
{% highlight bash %}
ansible-pull -U https://github.com/gabrielgio/homestation.git -C debcf3458df511aef9f7dca0cb73f6cf6baddd5d -i all main.yml
{% endhighlight %}

The idea here is to keep your repository as a source of truth when comes to configuration, you can add this task to your cron tab, so you just need to push something to your repository and after a few minutes not only your machine but all the machines that have it setup will receive an update. You can use this method as a simple way to install software, update machines or even distribute tools company-wise.
