Learn Ansible

By: Russ McKendrick

Overview of this book

Ansible has grown from a small, open source orchestration tool to a full-blown orchestration and configuration management tool owned by Red Hat. Its powerful core modules cover a wide range of infrastructures, including on-premises systems and public clouds, operating systems, devices, and services—meaning it can be used to manage pretty much your entire end-to-end environment. Trends and surveys say that Ansible is the first choice of tool among system administrators as it is so easy to use. This end-to-end, practical guide will take you on a learning curve from beginner to pro. You'll start by installing and configuring the Ansible to perform various automation tasks. Then, we'll dive deep into the various facets of infrastructure, such as cloud, compute and network infrastructure along with security. By the end of this book, you'll have an end-to-end understanding of Ansible and how you can apply it to your own environments.

Running the WordPress playbook

To run the playbook and install WordPress, we need a few things, starting with the inventory file called production:

box1 ansible_host=192.168.50.5.nip.io

[wordpress]
box1

[wordpress:vars]
ansible_connection=ssh
ansible_user=vagrant
ansible_private_key_file=~/.ssh/id_rsa
host_key_checking=False

As you can see, it takes into account the updated IP address of the Vagrant box we defined at the start of the chapter. Also, we need the playbook itself; site.yml should look as follows:

---

- hosts: wordpress
gather_facts: true
become: yes
become_method: sudo

vars_files:
- group_vars/common.yml

roles:
- roles/stack-install
- roles/stack-config
- roles/wordpress

Now, start the Vagrant box by running one of the following two commands:

$ vagrant up
$ vagrant up --provider=vmware_fusion

Once your Vagrant box is up and running, we can start the playbook...
