Ansible’s documentation indicates that inventory variables (in .yml files) are assigned with colons (“:”) and not equals (“=”) signs.

AWS used to have a separate API package from their CLI package; now the two are the same. OpenStack components’ command line interface activity is captured in a log when proper thresholds are set (e.g., nova.conf, glance.conf etc.) and later met. CLI activity (which bypasses Horizon) as well as GUI API activity (e.g., mouse clicks on buttons in Horizon) is written to a file named api.log. The location of this api.log file follows this convention: /var/log/OpenStackComponentName/api.log (where “OpenStackComponentName” is nova,
