Common Challenges Faced While Using Ansible Roles and Ways to Overcome Them

Ansible Roles are pre-defined collections of tasks, variables, and handlers that can be employed as the building blocks for creating playbooks. An Ansible Role is composed of the following components: tasks (the set of actions to be undertaken), variables (data utilized by the said tasks), files (which may be accessed by such aforementioned tasks), and handlers (which get executed at certain intervals within or between plays). Whilst making use of Ansible Roles, it is essential to bear in mind some common challenges that could arise. To begin with, one must ensure that any roles created are properly structured.

If a role is not organized effectively, complications may come to the fore when attempting to manage numerous roles and guarantee that they cooperate. A beneficial tactic for structuring the roles created is using a directory structure in which each role has its own ‘tasks’, ‘vars’, ‘templates’, and ‘handlers’ directories. This ascertains that all associated components of any given role are kept as one within an individual directory structure tree – making them easier to locate.

A further challenge may present itself when attempting to transfer variables from one role into another during the execution of a playbook. To effectuate this, it is suggested that Jinja2 filters or outputted variables stored in host facts or group vars files should be employed. Additionally, due consideration should also be given as regards how playbooks will handle sensitive information and all necessary steps must taken to avoid any superfluous exposure of credentials or other data that could potentially compromise the security of your systems.

It is recommended that passwords be stored in an encrypted form within files such as encrypted vault files, utilizing the ansible-vault command line tool, and referenced from there as needed in playbooks via lookup plugins or variable declarations. Furthermore, when constructing roles it is essential to bear potential changes in mind whenever upgrading versions of Ansible which could potentially have a deleterious effect on existing roles created based upon earlier versions. 

As always, the standard practice should dictate testing any updates thoroughly before implementing them into production environments – not only with regards to their functionality but also being mindful of licensing restrictions about proprietary software/packages used, etc. Subsequently, this will help ensure unexpected breakages can be avoided while simultaneously ensuring your deployment environment remains current with the latest features released along with bug fixes for all products managed by Ansible Roles.
