At its most basic, this is nothing more than an array or hash lookup,
but when used in conjunction with map, it is very useful. For example,
while constructing an "ssh-keyscan …" command to update known_hosts on
all hosts in a group, one can get a list of IP addresses with:
groups['x']|map('extract', hostvars, 'ec2_ip_address')|list
This returns hostvars[a].ec2_ip_address, hostvars[b].ec2_ip_address, and
so on. You can even specify an array of keys for a recursive lookup, and
mix string and integer keys depending on what you're looking up:
['localhost']|map('extract', hostvars, ['vars','group_names',0])|first
== hostvars['localhost']['vars']['group_names'][0]
== 'ungrouped'
Includes documentation and tests.

Homepage and documentation source for Ansible
This project hosts the source behind docs.ansible.com
Contributions to the documentation are welcome. To make changes, submit a pull request that changes the reStructuredText files in the "rst/" directory only, and the core team can do a docs build and push the static files.
If you wish to verify output from the markup
such as link references, you may install sphinx and build the documentation by running
make viewdocs from the ansible/docsite directory.
To include module documentation you'll need to run make webdocs at the top level of the repository. The generated
html files are in docsite/htmlout/.
If you do not want to learn the reStructuredText format, you can also file issues about documentation problems on the Ansible GitHub project.
Note that module documentation can actually be generated from a DOCUMENTATION docstring in the modules directory, so corrections to modules written as such need to be made in the module source, rather than in docsite source.
To install sphinx and the required theme, install pip and then "pip install sphinx sphinx_rtd_theme"
