Ansible Roles & Galaxy Flashcards

How are role dependencies defined so they are automatically executed before the parent role?

Answer: In meta/main.yml under the 'dependencies' key

Role dependencies listed under 'dependencies' in meta/main.yml are automatically resolved and executed before the role that declares them.

What is the difference between 'include_role' and 'import_role' in Ansible?

Answer: include_role is dynamic (evaluated at runtime); import_role is static (evaluated at parse time)

import_role is statically processed before playbook execution begins, while include_role is dynamically loaded during runtime allowing conditional inclusion.

What variable file in a role takes higher precedence than defaults/main.yml?

Answer: vars/main.yml

vars/main.yml has higher precedence than defaults/main.yml and is intended for internal role variables that should not be overridden.

How do you pass a variable to a role when including it in a playbook?

Answer: Under the role entry using 'vars:' or as key-value pairs inline

You can pass role-specific variables inline using key-value pairs or a vars: block under the role entry in the roles list.

What naming convention must a Galaxy role follow for its namespace and role name?

Answer: namespace.role_name using only letters, numbers, and underscores

Galaxy roles use the format namespace.role_name where both parts contain only alphanumeric characters and underscores.

Which file at the root of an Ansible Collection defines its namespace, name, and version?

Answer: galaxy.yml

galaxy.yml at the collection root defines the namespace, name, version, description, and dependencies of the collection.
