upgrade:
- |
In order to collect the default files used for various templates, the
implementation has been changed from using a git source to rather
using the built-in templates from the venv build based on the setup.cfg
file. As such, the following variables have been removed.
* ``keystone_git_config_lookup_location``
* ``keystone_paste_git_file_path``
* ``keystone_sso_callback_git_file_path``
Instead, a location on the deployment host where the venv defaults are
stored is now configurable using the variable
``keystone_config_cache_path`` which defaults to ``cache/keystone`` in
the deploy user home directory. This location is used as a template
source when deploying the file to the target host.

features:
- |
This consolidates the amphora image tasks in a common file and adds a way
to download an amphora image from an artefact storage over http(s). With
the Octavia team providing test images the tests were modified to not
build images any longer but download them.
security:
- |
It is commonly considered bad practice to downlaod random images from the
Internet expecially the test images the Octavia team provides which could
potentially include unpatched operating system packages - so for any
production deploy adjust the download url to an artifact storage your
organization controls. The system also does not authenticate the image
(e.g. with an md5) so should only be used on networks your organization
controls.

---
features:
- In a greenfield deployment containers will now bind link
their journals to the physical host machine in the
``/var/log/journal/{{ machine_id }}`` location. During an
upgrade this change will be added to the container config but
will not go into effect until the container is restarted.
Because the restart is not forced the operator can perform
restarts to best suit the needs of their environment.
Journal linking provides operators the ability to log stream
and health check containerized systems without having to
attach or otherwise login. If this feature is not needed or
desired it can be disabled by setting the option
``lxc_container_journal_link`` to *false*.

features:
- Within the lxc-container-create role the legacy networking scripts have been

single, common, networking functionality to across multiple distros.
- All of the pre/post up, and pre/post down adhoc command options have been

supported distros to benifit from the ability to run adhoc commands before

---
features:
- The option ``lxc_hosts_container_image_url`` has been added allowing
deployers to define their base image url to whatever it needs to be
removing the requirement for operators to maintain an internal LXC
index in the event they want to host a private repository.
- The option ``lxc_hosts_container_image_download_legacy`` has been
added allowing a deployer to enable the use of the legacy lxc image
repository. This option is a Boolean and has a default of **false**.
deprecations:
- The variable ``lxc_image_cache_server_mirrors`` has been deprecated
in the "lxc_hosts" role. This option has been replaced by the static
variable ``lxc_hosts_container_image_url``. This variable will continue
to function as a single element list allowing existing automation to
function when in legacy image mode but should not be considered in use
by default.
- The variable ``lxc_image_cache_server`` has been deprecated in the
``lxc_hosts`` role. This option has been replaced by the static
variable ``lxc_hosts_container_image_url``.
other:
- The use of **images.linuxcontainers.org** is no longer required. While
the images provided by that build system are perfectly functional they
have been less than optimal in a lot ways for a very long time. The
``lxc_hosts`` role will now pull a base image from the upstream distro
being deployed. If a deployer wishes to continue using the images from
**images.linuxcontainers.org** they are welcome to but it is no longer
forced.

The internal variable ``python_ceph_package`` has been renamed to
``python_ceph_packages`` and is now a list instead of a string.
If you are using gnocchi with ceph and are using this internal
variable in your ``ceph_extra_components`` overrides,
please update it to ``python_ceph_packages``.

features:
- The variable ``lxc_user_defined_container`` has been added to the lxc_hosts
role allowing deployers to define the variable file loaded when preparing a
base container image. This option defaults to using a base image most
closely associated with the underlying OS however should a deployer need,
this option can be used to customize the base container image for a given
host.

upgrade:
- The variable ``lxc_host_machine_volume_size`` now accepts any valid size
modifier acceptable by ``truncate -s`` and ``machinectl set-limit``.
prior to this change the option assumed an integer was set for some value
in gigabytes. All acceptable values can be seen within the
`documentation for machinectl <https://www.freedesktop.org/software/systemd/man/machinectl.html#set-limit%20%5BNAME%5D%20BYTES>`_
features:
- An option to disable the ``machinectl`` quota system has been added. The
variable ``lxc_host_machine_quota_disabled`` is a Boolean with a default of
**true**. When this option is set to **true** it will disable the
``machinectl`` quota system.
other:
- The variable ``lxc_host_machine_volume_size`` is used to set the size of
the default sparse file as well as define a limit within the ``machinectl``
quota system. When the ``machinectl`` quota system is enabled deployers
should appropriately set this value to the size of the container volume,
even when not using a sparse file.
- The container image cache within machinectl has been set to "64G" by
default.

deprecations:
- The option ``cache_prep_commands`` from ``lxc_cache_map`` has been
removed. This option has been converted to a template file within
the **lxc_hosts** role. In order to set specific cache commands within
the template it is recommended that deployers set
``lxc_cache_prep_pre_commands`` or ``lxc_cache_prep_post_commands``. If the
entire prep script needs to be overridden deployers can set
``lxc_cache_prep_template`` to the full local path of the prep template and
the role will use this script irrespective of the base container type.
