Ansible provides dynamic inventory scripts for many cloud providers and allows us to create dynamic inventory scripts as per our need for non-standard setups. We will use dynamic inventory in this book since it is better suited to cloud based environments. There are many ways to install Ansible. Most of the Linux distributions has Ansible packages in their repositories.
Compiling from source is also an option. However, for the sake of uniformity, we are going to use Python pip to install the same version of Ansible for all the readers. The following command will fetch the Ansible source and install Ansible 2. We have used this version of Ansible throughout the book and we urge our readers to install the same:.
The simplest form in which we can use Ansible with Ansible ad hoc command line tool. We can execute the tasks using modules without actually writing code in the file.
This is great for quick testing or for one off tasks but we should not turn this into a habit since this type of usage is not easily documented and auditable. We just have to use the Ansible command and pass the ping module as an argument to parameter -m. A successful execution will return the string pong. It signifies that Ansible can reach the server and execute tasks, subject to the authorization level of the user, of course:. Under normal circumstances, users execute the ansible-playbook command from a system, say A.
This system has inventory, playbooks, roles, variable definitions and other information required to configure a remote system, say B, to a desired state. When we talk about building infrastructure using Ansible, things change a bit.
Now, we are not configuring a remote system. We are actually interacting with a cloud provider to create or allocate certain resources to us. We may, at a later point in time, choose to configure these resources using Ansible as well. Interacting with a cloud provider is slightly different from executing a regular playbook. There are two important points that we need to keep in mind:.
Most of the time, during the course of this book, our playbooks will be running locally and interacting with a cloud provider. Generally, we need an inventory file, which has a record of all the hosts, for Ansible to run the playbooks. Let us try to work around it. The easiest way of running a playbook locally is by using the keyword localhost in the playbook as a value for the hosts key. This will save us from creating and managing the inventory file altogether.
Secret management is an important aspect of any configuration management tool. Ansible comes with a tool called Ansible Vault which encrypts secrets technically, it can encrypt any arbitrary file but we will focus on secrets at rest with bit AES encryption.
These secrets can be used in tasks in various ways. To understand this better, let us create a sample secret and use it in a task. We will begin with a standard variable file, let us call it secret. To use this in a playbook, we can include the file as a variable and call it in a task:.
Our goal is to protect the content of secret. So let us use ansible-vault and encrypt it:.
