What is the difference between Ansible role and module?
Modules can be written in any language, Ansible only ships with python and powershell modules. Roles are 'reusable subsets of a play', mainly they group tasks and resources to accomplish a certain goal, they have no host mapping and require being in a play.While automation tasks can be written exclusively in an Ansible Playbook, Ansible Roles allow you to create bundles of automation content that can be run in 1 or more plays, reused across playbooks, and shared with other users in collections.Ansible Role: Packages Ansible content—including tasks, handlers, variables, plugins, templates, and files—for use inside of a play. Ansible Roles can be imported into a play, reused in other plays or playbooks, and shared for use by other automation users.

What is the difference between Ansible playbook and Ansible module : Ansible modules are standalone scripts that can be used inside an Ansible playbook. A playbook consists of a play, and a play consists of tasks. These concepts may seem confusing if you're new to Ansible, but as you begin writing and working more with playbooks, they will become familiar.

What is basic Ansible role

Roles are sets of Ansible defaults, files, tasks, templates, variables, and other Ansible components that work together. As you saw on Run Your First Command and Playbook, moving from a command to a playbook makes it easy to run multiple tasks and repeat the same tasks in the same order.

What is the difference between terraform module and Ansible role : Terraform vs. Ansible: Highlighting the Differences. Terraform sets up and manages your IT infrastructure, using an infrastructure as code approach. Ansible, on the other hand, focuses on automating IT tasks like provisioning and deployment.

A role: what someone is expected to do (possibly the name of the position). A task is an individual job, a subset of one's responsible role.

How to create roles in Ansible: Step-by-step

  1. Step 1: Create the Ansible role folder.
  2. Step 2: Create the Ansible role using Ansible Galaxy.
  3. Step 3: Define Ansible role default variable.
  4. Step 4: Create a motd template.
  5. Step 5: Create the role task.
  6. Step 6: Create Ansible Playbook to use the role.

What is the difference between a module and a plugin in Ansible

Modules execute on the target system (usually that means on a remote system) in separate processes. Plugins augment Ansible's core functionality and execute on the control node within the /usr/bin/ansible process.Let us start by creating the role folder:

  1. Step 1: Create the Ansible role folder.
  2. Step 2: Create the Ansible role using Ansible Galaxy.
  3. Step 3: Define Ansible role default variable.
  4. Step 4: Create a motd template.
  5. Step 5: Create the role task.
  6. Step 6: Create Ansible Playbook to use the role.
  7. Step 7: Create an inventory file.

Ansible automates application deployment and manages configurations across servers or network devices. DevOps teams define the desired state of their infrastructure or applications using Ansible's declarative language (YAML) in Playbooks, which contains a series of tasks to be performed on target systems.

It is mainly used for configuring servers with the right software and updating already configured resources. Terraform does not support bare metal provisioning by default. Ansible supports the provisioning of bare metal servers. It does not provide better support in terms of packaging and templating.

Which one is better Ansible or Terraform : Both tools serve similar purposes, but they take different techniques and have other functionalities. Ansible is a powerful automation engine that makes configuration management and application deployment easier, whereas Terraform is a tool for building, updating, and versioning infrastructure safely and effectively.

Is roles and activities the same : Roles have a set of cohesive activities that they perform. These activities are closely related and functionally coupled, and are best performed by the same individual. Activities are closely related to artifacts.

What is the purpose of task roles

Task Roles. These are the roles that relate to getting the work done. They represent the different roles needed to take a project step-by-step from initial conception through to action.

Using roles at the play level

  1. If roles/x/tasks/main.yml exists, Ansible adds the tasks in that file to the play.
  2. If roles/x/handlers/main.yml exists, Ansible adds the handlers in that file to the play.
  3. If roles/x/vars/main.yml exists, Ansible adds the variables in that file to the play.

Section 1: Using Ansible Galaxy to initialize a new role

  1. Step 1:Navigate to your project. Navigate to your apache-basic-playbook project.
  2. Step 2: Create a directory. Create a directory called roles and cd into it.
  3. Step 3: Initialize new role.
  4. Step 4: Remove directories.

What is the difference between a module and a plugin : A module a quite generic terminology for a related set of classes that perform a task, and are usually bundled together in a jar file. A plugin is, like its name says, a piece of software that you can plug into an application to provide new functionality.
