Have You interested in automation using Ansible?
But don’t know where from You start?
Well, this course will learn You, how You can Know Automation within few months.This is a professional video course, created by an Automation Experts having 5+ years of experience in this field.This course starts with the architecture of Ansible. Ansible automation engine that’s automated cloud Multi-tier deployments provisioning configuration management application deployment intra service orchestration and many other IT needs.
Radically simple IT automation about practical, abstracts items.Playbook in Ansible is written in YAML format, commonly used for configuration files.Ansible defines a rich set up of variables, individual for each system.The course divided into six sections, starting with initial installation and foundation concepts.
Ansible used for many applications where data is being stored. Most of them which are defined previously to enable more flexibility in playbooks and roles. Apart from this uses values, Access various information like the hostname of the system and replace certain strings in templates with specific values. There is naming variable. Variable Names should be letters, numbers or underscores.
Mastering Ansible is a step by step journey of learning Ansible for configuration management and orchestration.Interesting Ansible course is designed by a journey through configuring a practical application stack from the ground.In addition the concepts of configuration management of Ansible we spent the time to build some tools to maintain troubleshoot our application.
The course is designed mainly for the introduction of Ansible but at the same time its a guide for Engineers interested in configuration management and orchestration, IT automation, infrastructure as code DevOps principles.Here is no required for previous programming and automation experience.
What is in this course?
The course introduces a beginner to basic fundamental of Ansible that you can easily do hands-on exercises right in the browser.The course provides basic use cases of Ansible followed by the introduction of an Ansible inventory, Configuration Management, patterns,
Playbooks, Modules, Conditionals, Loops and Roles, Ansible With Vagrant.
Let’s have a quick look what you are going to discuss throughout the whole course!
Ansible Inventory: At the same time Ansible works against multiple systems in your infrastructure. It does this by selecting portions of systems listed in Ansible inventory.
Ansible Configuration Management: Ansible is the simplest solution for configuration management.The descriptive data (both human readable and machine parsable) ensuring everyone and able to understand the meaning of each Configuration task.configuration management designed for consistent secure and highly reliable with the extremely low learning curve for Administrators, developers and IT manager.
Ansible Playbooks: Playbooks are Ansible’s configuration, deployment, and orchestration language. Many Ansible’s application which defined previously to enable more flexibility in playbooks.
Ansible With Vagrant: Ansible With Vagrant allows to provides the guest using Ansible Playbooks by executing Ansible Playbook from Vagrant host.General Ansible concepts like playbook or inventory are shortly explained in the introduction of Ansible With Vagrant.
Ansible Modules: The section discuss how to develop, debug, review and test modules. A number of Modules in Ansible ship called The Modules Library which can be executed mainly on a remote host or through playbooks.
What is so special in this course?
The course is very simple, awesome, easy to understand, agentless, parallel execution, automatic reporting easy to use and at the same time it is a time saver, In a few months you know the course and become more productive in your own goal. This is the one and the only course that provisions coding exercise were you can practice Ansible Playbook right in your browser.
How does Ansible work?
Ansible connecting your nodes and pushing out small programs.Ansible works very simple and different way of setting up the Architecture, SSH keys and their roles and Managing Inventory.
How does Ansible Playbook work?
Ansible playbook works as an Ansible configuration, deployment, and orchestration language.The playbook can finely orchestrate multiple slices of your infrastructure topology with very detail control over how many machines to tackle at the same time.
How does Ansible Tower work?
Ansible tower works as a scale IT automation, manage complex deployments and speed productivity.The Ansible tower allows us to easily streamline the delivery of applications and service to both OpenStack and Amazon clouds in a cost-effective simple and secure manner.
How does Ansible Vault work?
Ansible Vault is a feature of Ansible that keeps sensitive data such as password or keys in encrypted files rather than a plaintext in playbook or role.Ansible Vault encrypts anything inside a YAML file, with a password in your own choice.The vault file can distribute or place in source control.
What are the steps to start Ansible?
At first, Ansible installs your local machine.In order for Ansible to connect your VPS, you need to specify its IP address within Ansible host file.Test out your configuration by pinging your VPS for

In a previous guide, we discussed how to install the Ansible software and learn basic commands. In this guide, we will discuss Ansible playbooks, which are Ansible’s way of creating automated scripts to configure client computers.
We will assume that you have a configured Ansible server and a few clients, just as we left off in the last tutorial. In our guide, the server is a Ubuntu 12.04 machine, and the clients that we are going to be configuring are also Ubuntu 12.04 machines, for ease of explanation.
What are Ansible Playbooks?
Ansible playbooks are a way to send commands to remote computers in a scripted way. Instead of using Ansible commands individually to remotely configure computers from the command line, you can configure entire complex environments by passing a script to one or more systems.
Ansible playbooks are written in the YAML data serialization format. If you don’t know what a data serialization format is, think of it as a way to translate a programmatic data structure (lists, arrays, dictionaries, etc) into a format that can be easily stored to disk. The file can then be used to recreate the structure at a later point. JSON is another popular data serialization format, but YAML is much easier to read.
Each playbook contains one or more plays, which map hosts to a certain function. Ansible does this through something called tasks, which are basically module calls.
Note: We have not configured our host to handle PHP files at this time, so even if you did upload a PHP file, it would not be processed correctly.
This new version tries to upload a PHP index file to the host. It registers the success of the operation into a variable called “php”.
If this operation was successful, the task to remove the index.html file is run next.
If the operation failed, the index.html file is uploaded instead.
Now, you should have a good handle on how to automate complex tasks using Ansible. This is a basic example of how you can begin to build your configuration library.
Combining host and group definitions as we learned about in the first tutorial, and using available variables to fill in information, we can begin to put together complex computer systems that interact with each other. In a future article, we will discuss how to implement variables into our playbooks and create roles to help manage complex tasks.
