System administrators can use the :command:`openstack` and
|
|
:command:`euca2ools` commands to manage their clouds.
|
|
|
|
The ``openstack`` client and ``euca2ools`` can be used by all users, though
|
|
specific commands might be restricted by the Identity service.
|
|
|
|
**Managing the cloud with the openstack client**
|
|
|
|
#. The ``python-openstackclient`` package provides an ``openstack`` shell that
|
|
enables Compute API interactions from the command line. Install the client,
|
|
and provide your user name and password (which can be set as environment
|
|
variables for convenience), for the ability to administer the cloud from
|
|
the command line.
|
|
|
|
To install python-openstackclient, follow the instructions in the
|
|
`OpenStack User Guide
|
|
<https://docs.openstack.org/user-guide/common/cli-install-openstack-command-line-clients.html>`_.
|
|
|
|
#. Confirm the installation was successful:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack help
|
|
usage: openstack [--version] [-v | -q] [--log-file LOG_FILE] [-h] [--debug]
|
|
[--os-cloud <cloud-config-name>]
|
|
[--os-region-name <auth-region-name>]
|
|
[--os-cacert <ca-bundle-file>] [--verify | --insecure]
|
|
[--os-default-domain <auth-domain>]
|
|
...
|
|
|
|
Running :command:`openstack help` returns a list of ``openstack`` commands
|
|
and parameters. To get help for a subcommand, run:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack help SUBCOMMAND
|
|
|
|
For a complete list of ``openstack`` commands and parameters, see the
|
|
`OpenStack Command-Line Reference
|
|
<https://docs.openstack.org/cli-reference/openstack.html>`__.
|
|
|
|
#. Set the required parameters as environment variables to make running
|
|
commands easier. For example, you can add ``--os-username`` as an
|
|
``openstack`` option, or set it as an environment variable. To set the user
|
|
name, password, and project as environment variables, use:
|
|
|
|
.. code-block:: console
|
|
|
|
$ export OS_USERNAME=joecool
|
|
$ export OS_PASSWORD=coolword
|
|
$ export OS_TENANT_NAME=coolu
|
|
|
|
#. The Identity service gives you an authentication endpoint,
|
|
which Compute recognizes as ``OS_AUTH_URL``:
|
|
|
|
.. code-block:: console
|
|
|
|
$ export OS_AUTH_URL=http://hostname:5000/v2.0
