Environment sdb Module
:maintainer: SaltStack
:maturity: New
:depends: None
:platform: all
This module allows access to environment variables using an ``sdb://`` URI.
Example configuration for this module:
.. code-block:: yaml
osenv:
driver: env
WARNING:
--------
OS environment variables will be available
to read via SDB.
Please make sure you don't have any sensitive data
in your environment variables!!
Example usage of sdb env module:
.. code-block:: jinja
set some env var:
cmd.run:
- name: echo {{ salt['sdb.set']('sdb://osenv/foo', 'bar') }}
- order: 1
{% if salt['sdb.get']('sdb://osenv/foo') == 'bar' %}
always-changes-and-succeeds:
test.succeed_with_changes:
- name: foo
{% else %}
always-changes-and-fails:
test.fail_with_changes:
- name: foo
{% endif %}
The above example will return success.
The ``env`` sdb module can also be used with salt cloud.
Assuming you have exported the environment variable named
``compute`` (and have ``osenv`` defined).
The example below will look for the salt cloud config key ``compute_name``
in the environment:
.. code-block:: yaml
my-openstack-config:
compute_name: sdb://osenv/compute
