Settings

Introduction

Playbook comes with plethora of knobs to turn and tune.

Variable catalog

See default.yml.

Variable ordering

To understand how settings are applied it is important to know in which order Ansible evaluates different variables and configuration files.

Generally the order is this

• In vars section of your playbook.yml you put the basic settings which cannot be deduced from the context (git_repository)

• Then we include secrets.yml vault with all passwords and API tokens

• Then we apply defaults.yml which generates a lot of variables based on vars input which you usually don’t want to tune (database name, username, log file locations, etc.)

• If you are unhappy with defaults.yml results, you can create and include yet another file local-config.yml which overrides these

• Now you can still apply host and group specific variables as per Ansible manual
