After doing it a few times I came to the conclusion ( +[genius](https://i.imgur.com/BtWuQgT.png)) that It would be nice to +automate this chore. And as a result, I could tinker a little more with +my system and not be afraid of spending a weekend reinstalling +everything (which have happened more time that I'd like) + +So after a few attempts using python and bash, I couldn't get something +that scales and ended with many files and keep the files organized and +concise turned to be more tedious than the setup itself. So it comes +[Ansible](https://www.ansible.com/). It is an enterprise-grade software +used to automate tasks. It has many features I can be really helpful as +a sysadmin but what we gonna focus here is cliente side of thing using +[Ansible Pull](https://docs.ansible.com/ansible/latest/user_guide/playbooks_intro.html#ansible-pull) +and +[Playbooks](https://docs.ansible.com/ansible/latest/user_guide/playbooks.html) +as better describe: + +> Ansible-Pull is used to up a remote copy of ansible on each managed +> node, each set to run via cron and update playbook source via a source +> repository. This inverts the default push architecture of ansible into +> a pull architecture, which has near-limitless scaling potential. + +> Playbooks are Ansible’s configuration, deployment, and orchestration +> language. They can describe a policy you want your remote systems to +> enforce, or a set of steps in a general IT process. + +So what we're gonna do is pull a playbook from a git account a run on +the host, that playbook will have the tasks that we need to setup our +machine. + +To run it locally first we need localhost to all hosts list, to do so we +only the following text to `/etc/ansible/hosts`: + +{% highlight text %} +[all] +localhost +{% endhighlight %} + +As an experiment we're gonna make tasks to install vim. Currently, I +using +[Fedora](https://getfedora.org/) thus we going to use +[dnf modeule](https://docs.ansible.com/ansible/latest/modules/dnf_module.html) +to install packages + +The playbook to install is quite simple: + +{% highlight yml %} +# main.yml +- hosts: all tasks: + - name: install vim + dnf: + name: vim + state: latest +{% endhighlight %} + +Fist `hosts:` it is required and it has to match our hosts so we are +able to run that playbook. Then `tasks:` which is a list of task that +the playbook will perform that in this case will be `dnf install` for +the package vim. + +Ansible pull requires a repository but for the first example I want to +keep it simple so we will use `ansible-playbook` commando to run +`main.yml` direct from disk, do to so just run the following command: + +{% highlight bash %} +sudo ansible-playbook --connection=local main.yml +{% endhighlight %} + +After a few seconds, vim will be installed on your machine. +{% highlight bash %} +PLAY [all] ************************************************************* + +TASK [Gathering Facts] ************************************************* +ok: [localhost] + +TASK [install vim] ***************************************************** +ok: [localhost] + +PLAY RECAP ************************************************************* +localhost : ok=2 changed=0 unreachable=0 failed=0 +{% endhighlight %} + +This is the first step, next part we shall create a more complex +playbook and setup repo and actually use `ansible-pull` + + + + + + |
