Installation
|
|
------------
|
|
|
|
Fuel Octane is installed on the Fuel Master node. Version of ``fuel-octane``
|
|
package must match the version of Fuel.
|
|
|
|
To download the latest version of ``fuel-octane`` package on the Fuel Master
|
|
node, use the following command:
|
|
|
|
::
|
|
|
|
yum instal fuel-octane
|
|
|
|
Usage
|
|
-----
|
|
|
|
Backup Fuel configuration
|
|
=========================
|
|
|
|
Use this command to backup configuration of the Fuel Master node, environments
|
|
and target nodes:
|
|
|
|
::
|
|
|
|
octane fuel-backup --to=/path/to/backup.file.tar.gz
|
|
|
|
Backup Fuel repos and images
|
|
============================
|
|
|
|
Use this command to backup packages and images for all supported OpenStack
|
|
release bundles from the Fuel Master node:
|
|
|
|
::
|
|
|
|
octane fuel-repo-backup --full --to=/path/to/repo-backup.file.tar.gz
|
|
|
|
Restore Fuel configuration
|
|
==========================
|
|
|
|
Use this command to restore configuration of the Fuel Master node, environments
|
|
and target nodes:
|
|
|
|
::
|
|
|
|
octane fuel-restore --from=/path/to/backup.file.tar.gz --admin-password=<passwod>
|
|
|
|
Replace ``<password>`` with appropriate password for user ``admin`` in your
|
|
installation of Fuel.
|
|
|
|
Restore Fuel repos and images
|
|
=============================
|
|
|
|
Use this command to restore package repositories and images for OpenStack
|
|
release bundbles from backup file:
|
|
|
|
::
|
|
|
|
octane fuel-repo-restore --from=/path/to/repo-backup.file.tar.gz
|
|
|
|
Upgrade Fuel Master node
|
|
========================
|
|
|
|
Upgrade of Fuel Master node requires making both backups of configuration
|
|
and repos and images from older Fuel, as described above. Copy those files
|
|
to a secure location. After you create two backup files, install a new
|
|
(9.1) version of Fuel on the same physical node or on a new one.
|
|
|
|
.. note::
|
|
|
|
Please, note that you must specify the same IP address for the new
|
|
installation of the Fuel Master node as for the old one. Otherwise,
|
|
target nodes won't be able to communicate with the new Fuel Master
|
|
node.
|
|
|
|
Copy backup files to a new node from the secure location. Use ``octane`` to
|
|
restore Fuel configuration and packages from backup files. Database schema
|
|
will be upgraded according to migration scripts. See detailed commands above.
|
|
|
|
The Fuel Master node of new version must now have all configuration data from
|
|
an old version of the Fuel Master node.
|
|
|
|
Upgrade OpenStack cluster
|
|
=========================
|
|
|
|
Install 9.0 Seed environment
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

|
|
command and remember an ID of the environment you picked:
|
|
|
