python-brickclient
==================
* This element is aimed for providing cinder local attach/detach
functionality.
* Currently the feature has a dependency on a known bug
`<https://launchpad.net/bugs/1623549>`__, which has been resolved
and will be part of the upstream with the next release of
``python-brick-cinderclient-ext``. Note: Current version of
``python-brick-cinderclient-ext`` i.e. 0.2.0 requires and update to
be made in Line32 for
``/usr/share/python-brickclient/venv/lib/python2.7/site-packages/brick_cinderclient_ext/__init__.py``:
update ``brick-python-cinderclient-ext`` to
``python-brick-cinderclient-ext``.
Usage
-----
Pass the below shell script to parameter ``user-data`` and set
``config-drive=true`` at the time of provisioning the node via
nova-boot to make cinder local attach/detach commands talk to your
cloud controller.
.. code-block:: bash
#!/bin/bash
FILE="/etc/bash.bashrc"
[ ! -f "$FILE" ] && touch "$FILE"
echo 'export OS_AUTH_URL="http://<controller_ip>:5000/v2.0"' >> "$FILE"
echo 'export OS_PASSWORD="password"' >> "$FILE"
echo 'export OS_USERNAME="demo"' >> "$FILE"
echo 'export OS_TENANT_NAME="demo"' >> "$FILE"
echo 'export OS_PROJECT_NAME="demo"' >> "$FILE"
exec bash
To attach: ``/usr/share/python-brickclient/venv/bin/cinder local-attach <volume_id>``
To detach: ``/usr/share/python-brickclient/venv/bin/cinder local-detach <volume_id>``
Alternatively, the same action can be completed manually at the node
which does not require setting up of config drive such as:
.. code-block:: bash
/usr/share/python-brickclient/venv/bin/cinder \
--os-username demo --os-password password \
--os-tenant-name demo --os-project-name demo \
--os-auth-url=http://<controller_ip>:5000/v2.0 local-attach <volume_id>
