I set variables right in my playbooks to make tasks adapt on the fly. You pass them from inventory files too when servers differ a lot. And sometimes facts from the system fill in gaps without extra work. But precedence trips you up if hosts share names across groups. Also you override them during runs for quick checks on changes. Now templates pull these values to build config files cleanly. Perhaps you register output from one task and feed it forward next.
You keep secrets in vault files so they stay hidden during shares. I encrypt those early to avoid leaks in repos. And group vars let whole clusters inherit common settings fast. But host vars pin specifics to single machines without clutter. Also facts gather runtime details like memory sizes automatically. Then conditionals check variable states before skipping steps. Maybe loops repeat actions using lists stored in vars.
I debug by printing vars with debug calls to spot mismatches. You test overrides on command lines before committing edits. And roles import vars from defaults or vars folders easily. But extra vars from cli take highest priority always. Also you combine them with set fact for dynamic updates mid play. Perhaps environment vars from the shell influence behavior too. Now complex vars hold dicts for structured data handling.
You structure everything to reuse across projects without rewrites. I avoid hardcoding to prevent breaks on new hosts. And delegation passes vars between machines during runs. But filters transform values like joining paths or uppercasing strings. Also you source from external files for large datasets. Perhaps include vars from other roles to share logic. Then validate with assertions to catch bad values early.
