MRMCD2024 Entwicklung von Ansible Collections

Ansible Collections bundle roles, plugins, modules and other resources into reusable packages

Collections need proper namespaces and metadata to be published on Ansible Galaxy

Collections provide better error handling and validation compared to standalone roles

Key features include:

• Built-in “block” and “rescue” functionality
• First-found plugin for variable handling
• Integration with GitHub and other source control systems

Collections help standardize role structures and dependencies

Metadata defines important collection properties like:

• Platform compatibility
• Dependencies
• Role configurations
• Version requirements

Collections improve reusability and maintainability of Ansible code

Proper collection structure includes:

• Roles directory
• Plugin modules
• Documentation
• Galaxy metadata
• Task definitions

Collections enable better dependency management between different Ansible components

Collections support both community and custom private roles/modules

Variables and configurations can be better organized and validated within collections
