This patch refactors the ceph_client role to add support for multiple
operating system distros and multiple sources for Ceph packages.
The support of multiple sources for the Ceph packages is important
to organizations that must get packages from Canonical for service and
support. The current Ceph repo setup goes to upstream ceph.com
repositories and does not work with the UCA.
The use of UCA is also important when running OpenStack on the ppc64le
architecture because ceph.com does not have Debian packages available
for this architecture and the default trusty and trusty-updates repos
only have Ceph Giant, whereas the user can get later releases such as
Ceph Jewel from UCA.
The multiple operating system support for Trusty and Xenial also plays
into this since Xenial has Ceph Jewel by default. For Xenial OSA
deployments users may want to use the modern ceph client already
available for the distro.
The choice of which Ceph source to use is simple for deployers. They
simply set it with the ceph_pkg_source variable but have additional
variables they can tweak to pick specific Ceph versions from the
sources:
The ceph_pkg_source variable controls the install source for the
Ceph packages.
Valid values include:
* ceph This option installs Ceph from a ceph.com repo. Additional
variables to adjust items such as Ceph release and regional
download mirror can be found in vars/*.yml
* uca This option installs Ceph from the Ubuntu Cloud Archive.
Additional variables to adjust items such as the
OpenStack/Ceph release can be found in vars/*.yml.
* distro This options installs Ceph from the operating system's
default repository and unlike the other options does not
attempt to manage package keys or add additional package
repositories.

# to use Ceph in OSA, you need to
|
|
# - have the needed pools and a client user (for glance, cinder and/or nova)
|
|
# pre-provisioned in your ceph cluster; OSA assumes to have root access to
|
|
# the monitor hosts
|
|
# - configure / overrules following defaults in osa's user config
|
|
# - some ceph specific vars are (also) part of other role defaults:
|
|
# * glance
|
|
# * nova
|
|
