* Due to the takeover of freenode we're moving to a different irc network. * Our channels updated to point at the same channel name on libera.chat * Some links went to webchat.freenode.net. At this time, libera.chat doesn't point you to an official webchat client so I changed these to https://libera.chat. (kiwi irc does work with libera.chat so that could be another option). * In general, I used the name irc.libera.net for link names and https://libera.chat for link targets. This is because the irc service is hosted on irc.libera.chat but the project web server is hosted on libera.chat. (This appears to also be true for freenode but we were using http://irc.freenode.net which doesn't seem to work. Oops). * Removed http://irc.freenode.net from the linkcheck exceptions. linkcheck was actually correct to flag that as invalid (should have been http://frenode.net instead). * Looks like hte important people in #yaml are now in libera.chat * Link to where contributors should get help Add a link target and then link to where contributors should get support for developing groups of modules. * Update docs/docsite/rst/dev_guide/developing_modules_in_groups.rst Co-authored-by: Felix Fontein <felix@fontein.de> Co-authored-by: John R Barker <john@johnrbarker.com> Co-authored-by: Felix Fontein <felix@fontein.de>

Lookups

Lookup plugins retrieve data from outside sources such as files, databases, key/value stores, APIs, and other services. Like all templating, lookups execute and are evaluated on the Ansible control machine. Ansible makes the data returned by a lookup plugin available using the standard templating system. Before Ansible 2.5, lookups were mostly used indirectly in ``with_<lookup>`` constructs for looping. Starting with Ansible 2.5, lookups are used more explicitly as part of Jinja2 expressions fed into the ``loop`` keyword.

Using lookups in variables
|
|
==========================
|
|
|
|
You can populate variables using lookups. Ansible evaluates the value each time it is executed in a task (or template)::
|
|
|
|
vars:
|
|
motd_value: "{{ lookup('file', '/etc/motd') }}"
|
|
tasks:
|
|
- debug:
|
|
msg: "motd value is {{ motd_value }}"
|
|
|
|
For more details and a list of lookup plugins in ansible-core, see :ref:`plugins_lookup`. You may also find lookup plugins in collections. You can review a list of lookup plugins installed on your control machine with the command ``ansible-doc -l -t lookup``.
