How to use Ansible Loops ?

This article covers Ansible Loops and examples of using Loops in Ansible. In fact, to avoid repeating the task several times in your playbook file, it's better to use loops instead. A loop allows you to repeat instructions, typically until a certain condition is met. Ansible offers different looping methods, with the loop keyword being the most recommended option for longer term compatibility.


Ansible 'When' Conditionals - More about it ?

This article covers how to use the "when" clause in Ansible. In fact, In Ansible, you can define conditions that will be evaluated before a task is executed. When a condition is not met, the task is then skipped. This is done with the when keyword, which accepts expressions that are typically based on a variable or a fact.


Replace a String in a File Using Ansible

This article covers the usage of the 'replace' module in Ansible for replacing a string in a file. In fact, Ansible provide multiple ways that you can use to replace a string, an entire line or words that match a certain pattern. There are two modules that you can use to achieve this: the replace module and the inline module. 


How Tags in Ansible Playbook works running Ubuntu 22.04 (Jammy Jellyfish) ?

This article covers how to Use Tags in Ansible Playbook. In fact, you might want to run specific tasks instead of running an entire playbook file.  This helps to reduce the total playbook execution time, especially when dealing with a large playbook file.


Ansible "Debug" Module - Explained with Examples with Ubuntu

This article covers how to use the "debug" module with some examples. In fact, the Ansible "debug" module is very useful for actively debugging operations as we seen in the given examples. It is equally helpful for getting a verbose output from a playbook.


How do Ansible Debug works ?

  • msg: – This parameter accepts strings as inputs. This is used to print a customized message. If no message is given, then a generic message like “Hello World!” is
  • var: – This accepts strings as input and this is the variable that has been set either by Ansible facts or by the playbook. Also, the values written here will be having implicit double interpolation, as this option runs in the jinja2 context. So, you don’t need to use jinja2 delimiter unless you want to print double interpolation as well. You can use double interpolation when you print a variable in a
  • verbosity: – This has default as 0. This parameter is used to control when debug is in a run. For example if value 3 is given then debug will only run if -v or above is given while running the playbook.


Working with Variables in Ansible running Ubuntu 22.04 (Jammy Jellyfish)

This article covers the various types of variables used in Ansible. In fact, they are very useful for increasing the flexibility and comprehensibility of a code when used in an appropriate manner.

Basically, The use of variables simplifies the management of dynamic values throughout an Ansible project and can potentially reduce the number of human errors. 


Different types of variables in Ansible:
  • Global: this is set by config, environment variables and the command line. 
  • Play: each play and contained structures, vars entries, include_vars, role defaults and vars.
