Ansible is an open-source automation tool that allows users to configure and manage IT infrastructure efficiently; with Ansible, users can automate tasks such as deploying applications, configuring servers, and managing network devices.
This powerful tool uses a simple and intuitive syntax to define complex workflows and make it easy to automate repetitive tasks.
1. What is Ansible?
Ansible is a powerful tool for managing servers in DevOps environments, particularly in the operations side of the DevOps equation; it allows system administrators to maintain infrastructure for various servers within their company, such as web servers running Apache and database servers running MySQL.
2. What is Ansible designed to do?
Ansible is designed to help organisations with large infrastructures with hundreds of systems, making manual work tedious and prone to errors by automating configuration management, orchestration, and deployment of applications.
3. What is a group name in the Ansible host file?
A group name in the Ansible host file is used to add details for the client system, and the IP address of the client machine should follow it.
4. What is SSH in Ansible?
SSH (Secure Shell) is used for secure communication between the server or master system and the client or node system in Ansible.
5. What is YAML used for in Ansible?
YAML (YAML Yet Another Markup Language) is used to write playbooks in Ansible, playbooks are written in YAML, which is easy to write and understand.
6. What is a playbook in Ansible?
A playbook is a technical term for all configuration files written in Ansible, and playbooks specify the details of the configuration file or playbook that will be executed on the selected host systems.
7. What are the benefits of using Ansible?
Ansible allows small teams of system administrators to write simple codes and deploy them onto hundreds of servers, streamlining the process and reducing errors; this can help organisations streamline their processes and IT operations.
8. What is the purpose of creating the playbook using YAML?
Creating the playbook using YAML is to execute a script on a client machine.
9. What are the first and second tasks in the playbook?
The first task in the playbook is installing HTTPD, a patchy server, and the second is running an Apache service.
10. What is the third task in the playbook?
The third task in the playbook is to create a webpage that will be hosted, with the content being copied to a specific file location on the node system.
11. What happens if everything is fine after checking the syntax of the playbook?
The syntax of the playbook, the playbook, can be pushed onto the node or client machine.
12. How are the tasks in the playbook executed on the client machine?
The tasks in the playbook are executed on the client machine by Ansible, which gathers the client machine’s current state and checks what needs to be done; the tasks will be performed if the client machine is reachable and the content is available.
The Ansible documentation provides information on which tasks were executed and whether the client machine was reachable or unreachable.
13. What is Ansible Tower?
Ansible Tower is a secret source solution that can improve the speed and performance of creating Ansible environments; it allows for consistent deployment of servers into multiple areas, eliminating the need for manual setup procedures.
10. What are the three key areas within an operations environment that Ansible automates?
Ansible automates three critical areas within an operations environment: IT automation, which allows for creating and controlling IT setup instructions that would typically be done manually.
A consistent configuration ensures each Apache server is set up identically; deployment process automation allows for automatic deployment of different servers as the server environment scales up.
11. What is the pull configuration in Ansible?
Pull configuration in Ansible involves having a key server with instructions; on each server connected to it, a client is installed to communicate with the primary controller server and update or change the agent server’s configuration.
12. What is the push configuration in Ansible?
The push configuration in Ansible has a controller server where instructions are put up, but no client is installed on remote servers. Instead, the configuration is pushed out to those servers, forcing a restructure or fresh, clean installation in the environment.
13. How is an Ansible environment set up?
First, to set up an Ansible environment, create a local machine with all the instructions and controls pushed out to the remote server, connected from the local machine, and different nodes push out the configured configurations.
These configurations are written within modules and consistent playbooks on the local machine; the local machine also manages the inventory of nodes in the environment.
14. What specific tasks are executed in each server environment in Ansible?
In the server environment, specific tasks are executed, such as installing Apache, setting the state of the Apache environment, starting the Apache environment, and setting up and running the MySQL environment.
15. How does the inventory management part of Ansible maintain the structure of your network environment?
The inventory management part of Ansible maintains the structure of your network environment by creating two different nodes: a web server node and a database server node.
Under the web server node, the names are pointed to specific machines within that environment; when writing scripts, only the web server or database server will have the instructions from the Yammer script executed, making it easier to point to new services without writing complex instructions.
16. How does Ansible work in the real world?
In the real world, Ansible connects to different network nodes on a local machine. The first playbook on the local machine contains instructions for setting up remote nodes.
An inventory is created using secure SSH connections to each server to identify how to connect to these nodes; encrypting communication to those servers allows for basic information on each server, enabling remote configuration.
17. What does Ansible offer the significant opportunities over Chef and Puppet?
Ansible offers several significant opportunities over Chef and Puppet, including the ability to create consistent environments.
