Software Release Deployment in Distributed Cloud Overview
|
|
=========================================================
|
|
|
|
You can deploy a new software release on the System Controller then orchestrate
|
|
the software deployment across managed subclouds from the System Controller.
|
|
|
|
A central software release repository exists for each major release on the
|
|
System Controller. This is also used to store all patch releases for each
|
|
respective major release. All software releases must be uploaded to the System
|
|
Controller region i.e. by specifying ``--os-region-name SystemController`` in
|
|
the software upload command, so that they will be available for patch
|
|
application to both the Central Cloud and the managed subclouds.
|
|
|
|
When a new subcloud is deployed, it will be bootstrapped with the latest patch
|
|
that is available in the central software release repository for the specified
|
|
release.
|
|
|
|
Both major and minor software releases can be viewed, uploaded, deployed and
|
|
removed using CLI or Horizon dashboard. The same procedure is used to deploy
|
|
both types of software releases. After a new software release, major or minor,
|
|
has been uploaded to the central repository; it must be deployed first on the
|
|
Central Cloud, then prestaged on the subclouds and finally deployed on the
|
|
subclouds. However, the deployment of a major software release requires more
|
|
preparation which is described in a separate chapter.
|
|
|
|
.. note::
|
|
|
|
For Distributed Cloud, manual updating software of individual subclouds is
|
|
not recommended. |
