By: Fabio Alessandro Locati

Overview of this book

Ansible is an open source automation platform that assists organizations with tasks such as application deployment, orchestration, and task automation. With the release of Ansible 2.7, even complex tasks can be handled much more easily than before. Learning Ansible 2.7 will help you take your first steps toward understanding the fundamentals and practical aspects of Ansible by introducing you to topics such as playbooks, modules, and the installation of Linux, Berkeley Software Distribution (BSD), and Windows support. In addition to this, you will focus on various testing strategies, deployment, and orchestration to build on your knowledge. The book will then help you get accustomed to features including cleaner architecture, task blocks, and playbook parsing, which can help you to streamline automation processes. Next, you will learn how to integrate Ansible with cloud platforms such as Amazon Web Services (AWS) before gaining insights into the enterprise versions of Ansible, Ansible Tower and Ansible Galaxy. This will help you to use Ansible to interact with different operating systems and improve your working efficiency. By the end of this book, you will be equipped with the Ansible skills you need to automate complex tasks for your organization.

Using no_log

Ansible will hide your passwords only if you are using a specific set of keys. However, this might not be the case every time; moreover, you might also want to hide some other confidential data. The no_log feature of Ansible will hide your entire task from logging it to the syslog file. It will still print your task on stdout and log it to other Ansible log files.

At the time of writing this book, Ansible did not support hiding tasks from stdout using no_log.

Let's now see how you can hide an entire task with no_log:

- name: Running a script
  shell: script.sh
password: my_password no_log: True

By passing no_log: True to your task, Ansible will prevent the entire task from hitting syslog.
