Volume 2: Playbooks, Roles & Collections¶

Who This Volume Is For¶

Readers who understand why Ansible exists (Volume 1) and now need to actually build and organize real automation: inventories, variables, playbooks, reusable roles, and shareable collections.

Prerequisites¶

Volume 1: Fundamentals & History — particularly the declarative/idempotency mental model and a working Ansible install.

Chapters¶

1. CLI Deep Dive — ansible, ansible-playbook, ansible-config, ansible-doc, ansible-console, ansible-galaxy, ansible-vault
2. Inventory — static and dynamic inventory, INI and YAML formats, cloud inventory plugins, groups and patterns
3. Variables and Precedence — every variable source and the full precedence order, visualized
4. ansible.cfg — every major setting, search order, and performance-relevant tuning
5. Playbooks — every keyword: tasks, handlers, blocks, loops, conditionals, strategy, delegation, tags
6. Roles — role structure, Galaxy layout, and reusable role architecture
7. Collections — why collections were introduced, namespaces, versioning, dependencies
8. Galaxy — publishing, installing, requirements files, semantic versioning, signing

What You Will Be Able to Do After This Volume¶

• Write a production-shaped playbook using roles and collections rather than one giant flat file
• Reason confidently about which of a dozen possible sources set a given variable's final value
• Read and tune ansible.cfg instead of copy-pasting a stranger's config
• Publish and consume content from Ansible Galaxy correctly, with version pins
