Update Management for Distributed Cloud
|
|
=======================================
|
|
|
|
You can apply software updates (also known as 'patches') to the Central Cloud
|
|
and subclouds from the System Controller.
|
|
|
|
A central update repository on the Central Cloud is introduced for |prod-dc|.
|
|
This is used to store all updates (patches) so that unmanaged subclouds can
|
|
be synchronized with any required updates when they are brought into a managed
|
|
state.
|
|
|
|
To ensure the integrity of the |prod-dc| system, all updating must be done from
|
|
the Central Cloud.
|
|
|
|
.. caution::
|
|
|
|
Any updates that were applied to the Central Cloud prior to running
|
|
:command:`ansible bootstrap playbook`, including updates incorporated in
|
|
the installation ISO file and updates installed using :command:`sw-patch`
|
|
commands, must be uploaded to the System Controller. This ensures that the
|
|
updates are in the central update repository and the subclouds can be
|
|
updated with them.
|
|
|
|
You can use the Horizon Web interface or the command line interface to manage
|
|
updates. The workflow for patching is as follows:
|
|
|
|
|
|
.. _update-management-for-distributed-cloud-ul-pz2-gwd-rdb:
|
|
|
|
#. Review the update status of the systems in the |prod-dc|.
|
|
|
|
See :ref:`reviewing-update-status-for-distributed-cloud-using-horizon`.
|
|
|
|
#. Upload and apply any required updates to the System Controller. This adds
|
|
them to a Central Update Repository, making them available to the
|
|
SystemController and all subclouds.
|
|
|
|
See :ref:`uploading-and-applying-updates-to-systemcontroller-using-horizon`.
|
|
|
|
#. Update the Central Cloud's RegionOne and all subclouds with the updates
|
|
using update orchestration.
|
|
|
|
See :ref:`update-orchestration-of-central-clouds-regionone-and-subclouds`.
|
|
|
|
.. note::
|
|
For |prod-dc|, manual updating of individual subclouds is not recommended.
