ansible-mojo

Description

A simple introductory demo of Ansible playbook operations.

For a more in-depth discussion, check out this blog post.

Installation

Clone this repo down to the system you’ll be running Ansible from and make it your working directory
```
$ cd $HOME/code
$ git clone https://github.com/rcrelia/ansible-mojo.git
$ cd ansible-mojo
```
Create a symlink from /etc/ansible to $HOME/code/ansible-mojo
```
$ sudo ln -s /etc/ansible $HOME/code/ansible-mojo
```

Create a Vagrant VM using the image bento/xenial64 and VirtualBox as your provider

$ mkdir ~/vagrant-boxes/bento_ubuntu
$ cd ~/vagrant-boxes/bento_ubuntu
$ vagrant init bento/ubuntu-16.04; vagrant up --provider virtualbox

Configure the VM to be accessible via host lookups on your machine (e.g., add it to your /etc/hosts)
Add the vagrant user’s private key to your authentication chain/agent for passwordless access to the VM
```
$ ssh-add ~/vagrant-boxes/bento_ubuntu/.vagrant/machines/default/virtualbox/private_key
```

Create a RSA key to use for the ansible SSH user and populate $HOME/code/ansible/authorized_keys with it

$ ssh-keygen -t rsa -f ~/.ssh/ansible_key
$ cat ~/.ssh/ansible_key > $HOME/code/ansible-mojo/authorized_keys

Add this new RSA key to your authentication chain/agent for passwordless access to the VM as user “ansible”
```
$ ssh-add ~/.ssh/ansible_key
```

Install Ansible v2.2.0 from source repo on GitHub

$ cd $HOME/src
$ git clone -b stable-2.2 git://github.com/ansible/ansible.git --recursive
$ cd ./ansible
$ source ./hacking/env-setup

Add your Vagrant VM host to Ansible’s host inventory ($HOME/code/ansible-mojo/hosts)

Test Ansible operations with your Vagrant VM

$ ansible yourvmname -m setup -e ansible_ssh_user=vagrant

Usage

First run:

$ ansible-playbook main.yml -e ansible_ssh_user=vagrant

Subsequent runs:

$ ansible-playbook main.yml

Todo

Create more distro-agnostic plays (e.g., same play for both CentOS and Ubuntu)
Roles! Galaxy!
