============
clouds2env
============
A tool to convert from an OpenStack ``clouds.yaml`` file to environment
variables. This can be useful when all you have is a ``clouds.yaml`` file but
you need to work with a legacy tool like *novaclient*.
Like *openstacksdk*, *clouds2env* will look in the following location for
``clouds.yaml`` files:
* ``.`` (the current directory)
* ``$HOME/.config/openstack``
* ``/etc/openstack``
The first file found wins.
You can also set the environment variable ``OS_CLIENT_CONFIG_FILE`` to an
absolute path of a file to look for and that location will be inserted at the
front of the file search list.
You can specify the cloud to generate environment variables for by setting the
``OS_CLOUD`` environment variable. Alternatively, you may provide the cloud
name as an argument to tool.
Usage
-----
.. code-block:: shell
$ clouds2env --help
usage: clouds2env [-h] [--set | --unset] [cloud]
A tool to convert from an OpenStack 'clouds.yaml' file to 'OS_'-prefixed
environment variables suitable for use with legacy tooling like novaclient.
positional arguments:
cloud the cloud to use
options:
-h, --help show this help message and exit
--set set environment variables (default)
--unset unset environment variables
Example
-------
.. code-block:: shell
$ export OS_CLOUD=devstack-admin
$ clouds2env

export OS_PASSWORD=password
export OS_PROJECT_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_ID=default
