A Detailed Guide on Ansible Tower
By Hamid Akhtar, Community Contributor - August 8, 2023
Ansible Tower, a product of Red Hat, is a powerful automation tool that simplifies complex tasks. It provides a user-friendly dashboard, role-based access control, job scheduling, and graphical inventory management. This guide aims to delve into the intricacies of Ansible Tower, discussing its functionality, administration, and unique features.
It also explores how Ansible Tower enhances the capabilities of Ansible, making it more accessible and manageable. From setting up notifications for job templates to managing playbooks, this guide will provide a comprehensive understanding of Ansible Tower, making it an invaluable resource for both beginners and seasoned users.
What is Ansible Tower?
Consider the role of an air traffic controller at a busy airport. The controller’s job is to manage multiple flights, ensuring they take off, land, and navigate the airspace safely and efficiently. Now, imagine doing this job without a control tower – it would be chaotic, inefficient, and prone to errors.
Ansible Tower is like the control tower in this scenario, but for IT automation. It helps manage, control, and navigate through numerous automation tasks (flights) in a complex IT environment (airspace). It provides a visual dashboard, role-based access control, and features like job scheduling and inventory management to ensure that all your automation tasks are handled efficiently and safely, just like an air traffic controller ensures smooth operation at an airport.
Features of Ansible Tower
Imagine you’re a conductor of a grand orchestra. Each musician has a unique role, and they all need to play in harmony to create beautiful music. Now, consider Ansible Tower as your conductor’s baton, guiding the orchestra of your IT environment.
Let’s dive into the features of Ansible Tower that make it such an effective conductor:
- Visual Dashboard: Think of this as your music score. It gives you a graphical overview of all your automation tasks (musicians), allowing you to see who’s playing what, and when. It’s your go-to place for a quick status check.
- Role-Based Access Control (RBAC): This is like assigning roles to your musicians. You decide who plays the violin, who’s on the drums, and so on. In the same way, RBAC allows you to control who has access to what in your IT environment.
- Job Scheduling: This is your concert schedule. You can plan when each automation task (performance) should run. This is especially useful for tasks that need to be performed regularly.
- Real-Time Job Updates: This is like getting live feedback from your performance. You can see how your automation tasks are progressing in real time, allowing you to spot and fix any issues immediately.
- External Logging Integrations: This is your concert recording. Ansible Tower can integrate with external logging solutions, providing you with a detailed record of your automation ‘performances’.
- Multi-Playbook Workflows: This is your symphony. You can chain together multiple playbooks (musical pieces), creating complex workflows (symphonies) to handle sophisticated automation tasks.
- RESTful API: This feature allows Ansible Tower to ‘play’ with other tools and services, integrating them into your ‘orchestra’ and creating a harmonious IT environment.

Each of these features plays a crucial role in making Ansible Tower a comprehensive and efficient solution for IT automation. Just like a conductor’s baton, Ansible Tower guides your IT environment, ensuring everything works in harmony.
Ansible Tower Basics
Imagine you’re the director of a bustling city. Ansible Tower is like your city’s control center. It’s where you monitor everything that’s happening, make decisions, and implement those decisions. As the director, you use Ansible Tower to keep an eye on your city (IT environment), ensuring everything runs smoothly.
Think of roles as different departments in your city administration. Each department has a specific function and responsibilities. In Ansible Tower, roles are predefined ways for determining what actions are performed by different nodes in your IT infrastructure. As the city director, you assign roles to ensure that all tasks are covered.
Variables are like the different policies and guidelines you set for your city. They define how each department (role) operates and what actions they take. In Ansible Tower, variables are used to manage and control the behavior of your tasks, allowing you to customize your automation scripts according to your needs.
Modules are like the various tools and resources your city departments have at their disposal. Each tool (module) has a specific purpose and helps your departments (roles) carry out their tasks. In Ansible Tower, modules are units of code that Ansible executes. Each module has a specific function, like managing services, handling files, etc.
Tags are like the signs and labels around your city. They help you identify and categorize different areas and services. In Ansible Tower, tags allow you to run a specific part of your configuration without running the whole playbook. They provide you with fine control over what tasks to run and when.
Templates are like the blueprints for your city. They outline how everything should be structured and how it should function. In Ansible Tower, a job template is a definition and set of parameters for running an Ansible job. They are useful to execute the same job many times. As the city director, you use templates to ensure consistency and efficiency in your operations.
