[[{{< ref "2019-03-07-ansible-part-1.org " >}}][See part 1]]
Now we're going to setup ansible to work with a git repository. The process is
quite similar to ~ansible-playbook~, the only difference is that the source for
the playbook will be a remote repository and not a local file. Following the
previous example we'll get vim setup automated.
Create a git repository wherever you see fit, [[https://about.gitlab.com/][gitlab]] and [[https://github.com/][github]] offer free
repositories. For this task we 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 [[https://gitlab.com/gabrielgio/homestation/-/blob/debcf3458df511aef9f7dca0cb73f6cf6baddd5d/.vimrc][over here]], it is
pretty simple as I don't use it but for simple text editing (like this post) so
you can start with that if you don't have one.
The ~yml~ file will have two tasks, one is to install vim, just like we did in
the part 1.
#+BEGIN_SRC yaml
# main.yml
---
- name: install vim
dnf:
name: vim
state: latest
#+END_SRC
To copy ~.vimrc~ file to your ~$HOME~ we going to use [[https://docs.ansible.com/ansible/latest/modules/copy_module.html][copy module]]:
#+BEGIN_SRC yaml
# main.yml
---
- name: copy vimrc file
copy:
src: config/.vimrc
dest: ~/
mode: 0644
#+END_SRC
After we've added those two files to repository you will have be something [[https://gitlab.com/gabrielgio/homestation/-/tree/debcf3458df511aef9f7dca0cb73f6cf6baddd5d][like
this]].
And now we just need to run ~ansible-pull~ command
#+BEGIN_SRC shell
# you may need run it as a sudo
ansible-pull -U $YOUR_REPO -i all main.yml
#+END_SRC
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 its parameters.
The best part you can quickly test and see the result by running my sample:
#+BEGIN_SRC shell
ansible-pull -U https://gitlab.com/gabrielgio/homestation.git -C debcf3458df511aef9f7dca0cb73f6cf6baddd5d -i all main.yml
#+END_SRC
The idea here is to keep your repository as a source of truth when comes to
configuration, you can add ~ansible-pull~ to a 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 run the playbooks. You can use this
method as a simple way to install software, update machines or even distribute
tooling company-wise.
