Software Updates

|
|
|
|prod-long| software updates \(also known as patches\) must be applied to the
|
|
system in order to keep your system updated with feature enhancements, free of
|
|
known bugs, and security vulnerabilities.
|
|
|
|
|org| provides software updates that are cryptographically signed to ensure
|
|
integrity and authenticity. The |prod-long| REST APIs, CLIs and GUI validate
|
|
the signature of software updates before loading it into the system.
|
|
|
|
An update typically modifies a small portion of your system to address the
|
|
following items:
|
|
|
|
.. _software-updates-and-upgrades-software-updates-ul-gcd-smn-xw:
|
|
|
|
- bugs
|
|
|
|
- security vulnerabilities
|
|
|
|
- feature enhancements
|
|
|
|
Software updates can be installed manually or by the Update Orchestrator, which
|
|
automates a rolling install of an update across all of the |prod-long| hosts.
|
|
For more information on manual updates, see :ref:`Manage Software Updates
|
|
<managing-software-updates>`. For more information on upgrade orchestration,
|
|
see :ref:`Orchestrated Software Update <update-orchestration-overview>`.
|
|
|
|
.. warning::
|
|
Do NOT use the |updates-doc| guide for |prod-dc| orchestrated
|
|
software updates. The |prod-dc| Update Orchestrator automates a
|
|
recursive rolling install of an update across all subclouds and all hosts
|
|
within the subclouds.
|

.. xbooklink For more information, see, |distcloud-doc|: :ref:`Update Management for
|
|
Distributed Cloud <update-management-for-distributed-cloud>`.
|
|
|
|
|prod| handles multiple updates being applied and removed at once. Software
|
|
updates can modify and update any area of |prod| software, including the kernel
|
|
itself. For information on populating, installing and removing software
|
|
updates, see :ref:`Manage Software Updates <managing-software-updates>`.
|
|
|
|
There are two different kinds of Software updates that you can use to update
|
|
the |prod| software:

#. **Software Updates**
|
|
|
|
These software updates deliver |prod| software updates containing ostree
|
|
commits for updating the |prod| software running directly on the hosts.
|
|
|
|
Software updates can be installed manually or by the Update Orchestrator
|
|
which automates a rolling install of an update across all of the
|
|
|prod-long| hosts.
|
|
|
|
The |prod| handles multiple updates being applied and removed at once.
|
|
Software updates can modify and update any area of |prod| software,
|
|
including the kernel itself.
|
|
|
|
For information on populating, installing and removing software updates,
|
|
see :ref:`Manage Software Updates <managing-software-updates>`.
|
|
|
|
.. note::
|
|
A 10 GB internal management network is required for reboot-required
|
|
software update operations.
|
|
|
|
#. **Application Software Updates**
|
|
|
|
These software updates apply to software being managed through the
|
|
StarlingX Application Package Manager, that is, :command:`system
|
|
application-upload/apply/remove/delete`. |prod| delivers some software
|
|
through this mechanism, for example, ``platform-integ-apps``.
|
|
|
|
For software updates for these applications, download the updated
|
|
application tarball, containing the updated FluxCD manifest, and updated
|
|
Helm charts for the application, and apply the updates using the
|
|
:command:`system application-update` command.
