This page will show how to install a minimal non-HA OpenStack cloud. See
`Infrastructure high availability`_ for guidance on that subject.
Specification of software versions
----------------------------------
The cloud deployment involves two levels of software:
* charms (e.g. keystone charm)
* charm payload (e.g. Keystone service)
A charm's software version (its revision) is expressed via its channel (e.g.
'yoga/stable') whereas its payload is specified via its ``openstack-origin``
configuration option (e.g. 'distro' or 'cloud:focal-yoga'). See the Charm Guide
for more information:
* :doc:`cg:project/charm-delivery` for charms (channels)
* :doc:`cg:admin/upgrades/openstack` for charm payload (OpenStack software
sources)
.. note::
For a successful deployment, both the charm channel and the charm payload
must be compatible. Note also that the Ubuntu version is incorporated in the
charm payload value.
