OpenStack packages for Ubuntu
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Ubuntu releases OpenStack packages as part of each Ubuntu release and for
Ubuntu LTS releases via the Ubuntu Cloud Archive.
.. note::
The set up of OpenStack packages described here needs to be done on
all nodes: controller, compute, and Block Storage nodes.
.. warning::
Your hosts must contain the latest versions of base installation
packages available for your distribution before proceeding further.
.. note::
Disable or remove any automatic update services because they can
impact your OpenStack environment.
Enable the OpenStack repository
-------------------------------
**OpenStack Queens:**
.. code-block:: console
# apt install software-properties-common
# add-apt-repository cloud-archive:queens
**OpenStack Pike:**
.. code-block:: console
# apt install software-properties-common
# add-apt-repository cloud-archive:pike
.. note::
The Ubuntu Cloud Archive pockets for Pike and Queens provide
OpenStack packages for Ubuntu 16.04 LTS; OpenStack Queens is
installable direct using Ubuntu 18.04 LTS (due for release in
April 2018).
Finalize the installation
-------------------------
1. Upgrade the packages on all nodes:
.. code-block:: console
# apt update && apt dist-upgrade
.. note::
If the upgrade process includes a new kernel, reboot your host
to activate it.
2. Install the OpenStack client:
.. code-block:: console
# apt install python-openstackclient
