Current Series Release Notes¶

18.0.0.0b1-160¶

Support and documentation is added to the ceph_client role for enabling the Ceph Immutable Object Cache and the Peristent Write Log cache.

Added possibility to override ceph.conf partially by defining ceph_client_ceph_conf_overrides variable. It uses regular format of OpenStack-Ansible overrides. From now on, config_template plugin should be present for ansible.

Added variable ceph_cluster_name that allows ceph_client role to work with clusters that have non-default cluster name. It defaults to ceph.

Get ceph keyrings from files, if variable``ceph_keyrings_dir`` is defined the keyrings will be extracted from files. All files in the directory must have .keyring extention and be named with its corresponding ceph_client name. For example, if cinder_ceph_client is cinder the cinder keyring file must be named cinder.keyring. Each file must contain username and the key and nothing more, below an example for cinder.keyring content.
[client.cinder] key = XXXXXXXXXXX

The ceph_client role will now look for and configure manila services to work with ceph and cephfs.

Variable libvirt_package in ceph_client role has been renamed to libvirt_packages and converted from string to a list.

The data structure for ceph_gpg_keys has been changed to be a list of dicts, each of which is passed directly to the applicable apt_key/rpm_key module. As such any overrides would need to be reviewed to ensure that they do not pass any key/value pairs which would cause the module to fail.

The default values for ceph_gpg_keys have been changed for all supported platforms and now use vendored keys. This means that the task execution will no longer reach out to the internet to add the keys, making offline or proxy-based installations easier and more reliable.

A new value epel_gpg_keys can be overridden to use a different GPG key for the EPEL-7 RPM package repo instead of the vendored key used by default.

In the ceph_client role, the only valid values for ceph_pkg_source are now ceph and distro. For Ubuntu, the Ubuntu Cloud Archive apt source is already setup by the openstack_hosts role, so there is no need for it to also be setup by the ceph_client role.

Format of client key inside ceph_extra_components variable has been deprecated in favor of a mapping with one required attribute name. Having client key defined as a simple list is kept for backwards compatibility but will be removed in future releases.

Backwards compatibility of client key inside ceph_extra_components variable has been fixed to support both a list and a list of mappings.
