Configuring single-process ironic
|
|
---------------------------------
|
|
|
|
As an alternative to starting separate API and conductor instances, you can
|
|
start ``ironic`` services that combine an API and a conductor in the same
|
|
process. This may be particularly beneficial in environments with limited
|
|
resources and low number of nodes to handle.
|
|
|
|
.. note:: This feature is available starting with the Yoga release series.
|
|
|
|
#. Start with setting up the environment as described in both `Configuring
|
|
ironic-api service`_ and `Configuring ironic-conductor service`_, but do not
|
|
start any services. Merge configuration options into a single configuration
|
|
file.
|
|
|
|
.. note::
|
|
Any RPC settings will only take effect if you have more than one combined
|
|
service started or if you have additional conductors.
|
|
|
|
If you don't plan to have more than one conductor, you can disable the
|
|
RPC completely:
|
|
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
rpc_transport = none
|
|
|
|
#. Stop existing services if they are already started:
|
|
|
|
Fedora/RHEL/CentOS/SUSE::
|
|
|
|
sudo systemctl stop openstack-ironic-api
|
|
sudo systemctl stop openstack-ironic-conductor
|
|
|
|
Ubuntu::
|
|
|
|
sudo service ironic-api stop
|
|
sudo service ironic-conductor stop
|
|
|
|
#. Start or restart the ironic service:
|
|
|
|
Fedora/RHEL8/CentOS8/SUSE::
|
|
|
|
sudo systemctl restart openstack-ironic
|
|
|
|
Ubuntu::
|
|
|
|
sudo service ironic restart
