What is Ansible? Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy. Avoid writing scripts or custom code to deploy and update your applications— automate in a language that approaches plain English, using SSH, with no agents to install on remote systems. For anyone in the IT automation or DevOps engineering fields, learning the basics of Ansible is important. What Are the Benefits to Learning Ansible Basics? - A free and open-source community project with a huge audience. - Battle-tested over many years as the preferred tool of IT wizards. - Easy to start and use from day one, without the need for any special coding skills. - Simple deployment workflow without any extra agents. - Includes some sophisticated features around modularity and reusability that come in handy as users become more proficient. - Extensive and comprehensive official documentation that is complemented by a plethora of online material produced by its community. Ansible Basics Course Details This course introduces a beginner to the basic fundamentals of Ansible with easy-to-do hands-on exercises that you can practice right in the browser. The course helps users learn Ansible’s basics, followed by an introduction to * Ansible Inventory: A list of managed nodes provided by one or more ‘inventory sources’. Your inventory can specify information specific to each node, like IP address. It is also used for assigning groups, that both allow for node selection in the Play and bulk variable assignment. * Ansible Playbooks: A playbook is composed of one or more ‘plays’ in an ordered list. The terms ‘playbook’ and ‘play’ are sports analogies. Each play executes part of the overall goal of the playbook, running one or more tasks. Each task is called an Ansible module. Playbooks are expressed in YAML format with a minimum of syntax. * Ansible Modules: The code or binaries that Ansible copies and executes on each managed node (when needed) to accomplish the action defined in each Task. Each module has a particular use, from administering users on a specific type of database to managing VLAN interfaces on a specific type of network device. You can invoke a single module with a task or invoke several different modules in a playbook. Ansible modules are grouped in collections. * Ansible Variables: Ansible uses variables to manage differences between systems. With Ansible, you can execute tasks and playbooks on multiple different systems with a single command. To represent the variations among those different systems, you can create variables with standard YAML syntax, including lists and dictionaries. You can define these variables in your playbooks, in your , in re-usable or , or at the command line. You can also create variables during a playbook run by registering the return value or values of a task as a new variable. * Ansible Conditionals: In a playbook, you may want to execute different tasks or have different goals depending on the value of a fact (data about the remote system), a variable, or the result of a previous task. You may want the value of some variables to depend on the value of other variables. Or you may want to create additional groups of hosts based on whether the hosts match other criteria. You can do all of these things with conditionals. * Ansible Loops : Ansible offers the , , and `` keywords to execute a task multiple times. * Ansible Roles: A limited distribution of reusable Ansible content (tasks, handlers, variables, plugins, templates, and files) for use inside of a Play. To use any Role resource, the Role itself must be imported into the Play.

Those new to the Cloud and DevOps world often find it difficult to start their journey due to missing basic prerequisites. For example, issues with setting up a basic lab environment using VirtualBox, networking issues, or working with the Linux CLI or text editors like vi editor. Sometimes, it's issues with applications – like getting a sample application to work, getting the dependencies to install properly, or getting a webserver to communicate with a database server. Or at other times, it's working with data formats like JSON or YAML. So we have identified a gap, and we believe that this is because some of the basic prerequisites are missing, such as knowing the basics of Linux, the basics of tools like VirtualBox, the basics of the most commonly used applications like Java, Python, NodeJS, or web servers like Apache, NGINX, etc. As a DevOps or Cloud Engineer it is important to have these basics cleared. And that’s why we built this course to bridge that gap. With this course, anyone can kick start their DevOps or Cloud Journey. This is the course you must take before you start with any of the DevOps or Cloud courses out there. This course helps you get your basics right so the rest of the journey is smooth. What are the prerequisites to attend this course? - There are no pre-requisites for this pre-requisites course - Good to have (Not Mandatory) a laptop to practice by yourself

What is GIT? What is the single most important tool that Developers and Operations teams must know alike today? Git! Git is a distributed version control system that allows developers and operations teams to collaborate and keep track of the changes made on a project. GIT, as a DevOps tool, empowers collaboration and faster release cycles. Anyone willing to start their DevOps career or level up should start from the basics, and GIT is the most fundamental requirement of all. Why You Should Use GIT Many of the most popular open-source projects today are developed on Github – Kubernetes, Ansible, Tensor Flow, Rust, Node.js, Go, Terraform, and Helm Charts being some of the top ones among the 100 million repositories. If you would like to learn and contribute to these projects, understanding Git is a must, and our GIT for beginners course is here to help!

Jenkins is one of the most popular tools used worldwide for continuous integration and continuous delivery. Jenkins is a free and open-source automation server. It enables developers to build, integrate, and test code automatically as soon as it is committed to the source repository. This enables developers to detect errors and bugs at an early stage and deploy more swiftly. It helps in better collaboration between the developers as it takes the latest code and triggers a build as soon as it is added to the shared repository by any developer and notifies if the build was successful or not saving the time and effort by not wasting time looking for bugs. In this course, you will learn with demos at each step for better visualization of the concepts about what CI/CD is, why we should use Jenkins, how to create pipelines, use of different plugins, Jenkins security and much more along with the hands-on practice for these concepts to give you a solid foundation of Jenkins. Some of the concepts covered in this course are listed below: - What is CI/CD - Why Jenkins? - Installing Jenkins - Jenkins CLI - Plugins - Managing users and teams - Managing the system and credentials - Administering Jenkins - Backup Jenkins - Restore Jenkins - Jenkins Pipelines
