Understanding the release cycle
|
|
-------------------------------
|
|
|
|
There is a new stable release cycle every nine (9) months, starting
|
|
after the Luminous release (12.2.0). Each stable release series will
|
|
receive a name (e.g., 'Mimic') and a major release number (e.g., 13
|
|
for Mimic because 'M' is the 13th letter of the alphabet).
|
|
|
|
Releases are named after a species of cephalopod (usually the common
|
|
name, since the latin names are harder to remember or pronounce).
|
|
|
|
Version numbers have three components, *x.y.z*. *x* identifies the release
|
|
cycle (e.g., 13 for Mimic). *y* identifies the release type:
|
|
|
|
* x.0.z - development releases (for early testers and the brave at heart)
|
|
* x.1.z - release candidates (for test clusters, brave users)
|
|
* x.2.z - stable/bugfix releases (for users)
|
|
|
|
This versioning convention started with the 9.y.z Infernalis cycle. Prior to
|
|
that, versions looked with 0.y for development releases and 0.y.z for stable
|
|
series.
|
|
|
|
Development releases (x.0.z)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Each development release (x.0.z) freezes the master development branch
|
|
and applies `integration and upgrade tests
|
|
<https://github.com/ceph/ceph/tree/master/qa/suites/>`_ before it is released. Once
|
|
released, there is no effort to backport fixes; developer focus is on
|
|
the next development release which is usually only a few weeks away.
|
|
|
|
* Development release every 4 to 8 weeks
|
|
* Intended for testing, not production deployments
|
|
* Full integration testing
|
|
* Upgrade testing from the last stable release(s)
|
|
* Every effort is made to allow *offline* upgrades from previous
|
|
development releases (meaning you can stop all daemons, upgrade, and
|
|
restart). No attempt is made to support online rolling upgrades
|
|
between development releases. This facilitates deployment of
|
|
development releases on non-production test clusters without
|
|
repopulating them with data.
|
|
|
|
Release candidates (x.1.z)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
There is a feature release roughly six (6) weeks prior to the planned
|
|
initial stable release, after which focus shifts to stabilization and
|
|
bug fixes only.
|
|
|
|
* Release candidate release every 1-2 weeks
|
|
* Intended for final testing and validation of the upcoming stable release
|
|
|
|
Stable releases (x.2.z)
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Once the initial stable release is made (x.2.0), there are
|
|
semi-regular bug-fix point releases with bug fixes and (occasionally)
|
|
small feature backports. Bug fixes are accumulated and included in
|
|
the next point release.
|
|
|
|
* Stable point release every 4 to 6 weeks
|
|
* Intended for production deployments
|
|
* Bug fix backports for two full release cycles.
|
|
* Online, rolling upgrade support and testing from the last two (2)
|
|
stable release(s) (starting from Luminous).
|
|
* Online, rolling upgrade support and testing from prior stable point
|
|
releases
|
|
|
|
For each stable release:
|
|
|
|
* `Integration and upgrade tests
|
|
<https://github.com/ceph/ceph/tree/master/qa/suites/>`_ are run on a regular basis
|
|
and `their results <http://pulpito.ceph.com/>`_ analyzed by Ceph
|
|
developers.
|
|
* `Issues <http://tracker.ceph.com/projects/ceph/issues?query_id=27>`_
|
|
fixed in the development branch (master) are scheduled to be backported.
|
|
* When an issue found in the stable release is `reported
|
|
<http://tracker.ceph.com/projects/ceph/issues/new>`_, it is
|
|
triaged by Ceph developers.
|
|
* The `stable releases and backport team <http://tracker.ceph.com/projects/ceph-releases/wiki>`_
|
|
publishes ``point releases`` including fixes that have been backported to the stable release.
|
|
|
|
In the timeline above, the life time of a stable release series is
|
|
calculated to be approximately 18 months (i.e., two 9 month release
|
|
cycles) after the month of the first release. For example, Luminous
|
|
(12.2.z) will reach end of life (EOL) shortly after Nautilus (14.2.0) is
|
|
released. The lifetime of a release may vary because it depends on how
|
|
quickly the stable releases are published.
|
|
|
|
The life time for Jewel and Kraken are slightly different. Prior to
|
|
Luminous, only every other stable release was an "LTS" release.
|
|
Therefore,
|
|
|
|
* Upgrades are supported from Jewel -> Kraken -> Luminous and Jewel -> Luminous.
|
|
* Upgrades from Jewel or Kraken must upgrade to Luminous first before proceeding further (e.g., Kraken -> Luminous -> Mimic but not Kraken -> Mimic).
|
|
* Jewel will be maintained until Mimic is released in the spring of 2018.
|
|
* Kraken is no longer maintained.
