===========

Strategies are a way to control play execution. By default, plays run with a `` linear `` strategy, in which all hosts will run each task before any host starts the next task, using the number of forks (default 5) to parallelize.

The `` serial `` directive can 'batch' this behaviour to a subset of the hosts, which then run to
completion of the play before the next 'batch' starts.

A second `` strategy `` ships with Ansible - `` free `` - which allows each host to run until the end of

the play as fast as it can.::

The strategies are implemented as plugins. In the future, new
execution strategies can be added, either locally by users or to Ansible itself by
2015-07-17 19:53:13 +02:00
a code contribution.

One example is `` debug `` strategy. See :doc: `playbooks_debugger` for details.
