Lookup Plugins
|
||||
--------------
|
||||
|
||||
Lookup plugins allow Ansible to access data from outside sources.
|
||||
This can include reading the filesystem in addition to contacting external datastores and services.
|
||||
Like all templating, these plugins are evaluated on the Ansible control machine, not on the target/remote.
|
||||
|
||||
The data returned by a lookup plugin is made available using the standard templating system in Ansible,
|
||||
and are typically used to load variables or templates with information from those systems.
|
||||
|
||||
Lookups are an Ansible-specific extension to the Jinja2 templating language.
|
||||
|
||||
.. note::
|
||||
- Lookups are executed with a working directory relative to the role or play,
|
||||
as opposed to local tasks, which are executed relative the executed script.
|
||||
- Since Ansible version 1.9, you can pass wantlist=True to lookups to use in Jinja2 template "for" loops.
|
||||
- Lookup plugins are an advanced feature; to best leverage them you should have a good working knowledge of how to use Ansible plays.
|
||||
|
||||
.. warning::
|
||||
- Some lookups pass arguments to a shell. When using variables from a remote/untrusted source, use the `|quote` filter to ensure safe usage.
|
||||
|
||||
|
||||
.. _enabling_lookup:
|
||||
|
||||
Enabling Lookup Plugins
|
||||
+++++++++++++++++++++++
|
||||
|
||||
You can activate a custom lookup by either dropping it into a ``lookup_plugins`` directory adjacent to your play, inside a role, or by putting it in one of the lookup directory sources configured in :doc:`ansible.cfg <../config>`.
|
||||
|
||||
|
||||
.. _using_lookup:
|
||||
|
||||
Using Lookup Plugins
|
||||
++++++++++++++++++++
|
||||
|
||||
Lookup plugins can be used anywhere you can use templating in Ansible: in a play, in variables file, or in a Jinja2 template for the :doc:`template <../template_module>` module.
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
vars:
|
||||
file_contents: "{{lookup('file', 'path/to/file.txt')}}"
|
||||
|
||||
Lookups are an integral part of loops. Wherever you see ``with_``, the part after the underscore is the name of a lookup.
|
||||
This is also the reason most lookups output lists and take lists as input; for example, ``with_items`` uses the :doc:`items <lookup/items>` lookup:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
tasks:
|
||||
- name: count to 3
|
||||
debug: msg={{item}}
|
||||
with_items: [1, 2, 3]
|
||||
|
||||
You can combine lookups with :doc:`../playbooks_filters`, :doc:`../playbooks_tests` and even each other to do some complex data generation and maniplulation. For example:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
tasks:
|
||||
- name: valid but useless and over complicated chained lookups and filters
|
||||
debug: msg="find the answer here:\n{{ lookup('url', 'http://google.com/search/?q=' + item|urlencode)|join(' ') }}"
|
||||
with_nested:
|
||||
- "{{lookup('consul_kv', 'bcs/' + lookup('file', '/the/question') + ', host=localhost, port=2000')|shuffle}}"
|
||||
- "{{lookup('sequence', 'end=42 start=2 step=2')|map('log', 4)|list)}}"
|
||||
- ['a', 'c', 'd', 'c']
