===========
|
|
|
|
In 2.0 we added a new way to control play execution, ``strategy``, by default plays will
|
|
still run as they used to, with what we call the ``linear`` strategy. All hosts will run each
|
|
task befor 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:
|
|
...

|
|
|
|
The strategies are implelented via a new type of plugin, this means that in the future new
|
|
execution types can be added in the future, either locally by users or to Ansible itself by
|
|
a code contribution.
