Strategies
|
|
===========
|
|
|
|
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.::
|
|
|
|
- hosts: all
|
|
strategy: free
|
|
tasks:

Strategy Plugins

`````````````````
|
|
|
|
The strategies are implemented as plugins. In the future, new
|
|
execution strategies can be added, either locally by users or to Ansible itself by
|
|
a code contribution.
|
|
|
|
One example is ``debug`` strategy. See :doc:`playbooks_debugger` for details.
