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.

WordPress on DigitalOcean

Now we have a playbook that launches a Droplet, we are going to make a slight adaptation and install WordPress on the Droplet we launch. To do this, make a copy of the folder that holds the playbook we just ran and call it digitalocean-wordpress. Copy the three roles, stack-install, stack-config, and wordpress, from the Chapter06/lemp-multi/roles folder.

The host inventory

The first file we are going to change is the host inventory file called production; this needs to be updated to be the following:

[droplets]

[digitalocean:children]
droplets

[digitalocean:vars]
ansible_ssh_user=root
ansible_ssh_private_key_file=~/.ssh/id_rsa
host_key_checking=False
ansible_python_interpreter=/usr/bin/python
