Compute drivers now expose capabilities via traits in the
|
|
Placement API. Capabilities must map to standard traits defined
|
|
in `the os-traits project
|
|
<https://docs.openstack.org/os-traits/latest/>`_; for now these
|
|
are:
|
|
|
|
* ``COMPUTE_NET_ATTACH_INTERFACE``
|
|
* ``COMPUTE_DEVICE_TAGGING``
|
|
* ``COMPUTE_NET_ATTACH_INTERFACE_WITH_TAG``
|
|
* ``COMPUTE_VOLUME_ATTACH_WITH_TAG``
|
|
* ``COMPUTE_VOLUME_EXTEND``
|
|
* ``COMPUTE_VOLUME_MULTI_ATTACH``
|
|
* ``COMPUTE_TRUSTED_CERTS``
|
|
|
|
Any traits provided by the driver will be automatically added
|
|
during startup or a periodic update of a compute node. Similarly
|
|
any traits later retracted by the driver will be automatically
|
|
removed.
|
|
|
|
However any traits which are removed by the admin from the compute
|
|
node resource provider via the Placement API will not be
|
|
reinstated until the compute service's provider cache is reset.
|
|
This can be triggered via a ``SIGHUP``.
