======================
Ceph Release Process
======================
1. Build environment
====================
There are multiple build environments, debian based packages are built via pbuilder for multiple distributions. The build hosts are listed in the ``deb_hosts`` file, and the list of distributions are in ``deb_dist``. All distributions are build on each of the build hosts. Currently there is 1 64 bit and 1 32 bit build host.
The RPM based packages are built natively, so one distribution per build host. The list of hosts is found in ``rpm_hosts``.
Prior to building, it's necessary to update the pbuilder seed tarballs::
./update_all_pbuilders.sh
2. Setup keyring for signing packages
=====================================
::
export GNUPGHOME=<path to keyring dir>
# verify it's accessible
gpg --list-keys
The release key should be present::
pub 4096R/17ED316D 2012-05-20
uid Ceph Release Key <sage@newdream.net>
3. Set up build area
====================
Clone the ceph and ceph-build source trees::
git clone http://github.com/ceph/ceph.git
git clone http://github.com/ceph/ceph-build.git
In the ceph source directory, checkout next branch (for point releases use the {codename} branch)::
git checkout next
Checkout the submodules::
git submodule update --force --init --recursive
4. Update Build version numbers
================================
Substitute the ceph release number where indicated below by the string ``0.xx``.
Edit configure.ac and update the version number. Example diff::
-AC_INIT([ceph], [0.54], [ceph-devel@vger.kernel.org])
+AC_INIT([ceph], [0.55], [ceph-devel@vger.kernel.org])
Update the version number in the debian change log::
DEBEMAIL user@host dch -v 0.xx-1
Commit the changes::
git commit -a
Tag the release::
../ceph-build/tag-release v0.xx
5. Create Makefiles
===================
The actual configure options used to build packages are in the
``ceph.spec.in`` and ``debian/rules`` files. At this point we just
need to create a Makefile.::
./do_autogen.sh
6. Run the release scripts
==========================
This creates tarballs and copies them, with other needed files to
the build hosts listed in deb_hosts and rpm_hosts, runs a local build
script, then rsyncs the results back to the specified release directory.::
../ceph-build/do_release.sh /tmp/release
7. Create RPM Repo
==================
Copy the rpms to the destination repo::
mkdir /tmp/rpm-repo
../ceph-build/push_to_rpm_repo.sh /tmp/release /tmp/rpm-repo 0.xx
Next add any additional rpms to the repo that are needed such as leveldb and
and ceph-deploy. See RPM Backports section
Finally, sign the rpms and build the repo indexes::
../ceph-build/sign_and_index_rpm_repo.sh /tmp/release /tmp/rpm-repo 0.xx
8. Create Debian repo
=====================
The key-id used below is the id of the ceph release key from step 2::
mkdir /tmp/debian-repo
../ceph-build/gen_reprepro_conf.sh /tmp/debian-repo key-id
../ceph-build/push_to_deb_repo.sh /tmp/release /tmp/debian-repo 0.xx main
Next add any addition debian packages that are needed such as leveldb and
ceph-deploy. See the Debian Backports section below.
Debian packages are signed when added to the repo, so no further action is
needed.
9. Push repos to ceph.org
==========================
For a development release::
rcp ceph-0.xx.tar.bz2 ceph-0.xx.tar.gz \
ceph_site@ceph.com:ceph.com/downloads/.
rsync -av /tmp/rpm-repo/0.xx/ ceph_site@ceph.com:ceph.com/rpm-testing
rsync -av /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-testing
For a stable release, replace {CODENAME} with the release codename (e.g., ``argonaut`` or ``bobtail``)::
rcp ceph-0.xx.tar.bz2 \
ceph_site@ceph.com:ceph.com/downloads/ceph-0.xx.tar.bz2
rcp ceph-0.xx.tar.gz \
ceph_site@ceph.com:ceph.com/downloads/ceph-0.xx.tar.gz
rsync -av /tmp/rpm-repo/0.xx/ ceph_site@ceph.com:ceph.com/rpm-{CODENAME}
rsync -auv /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-{CODENAME}
10. Update Git
==============
Point release
-------------
For point releases just push the version number update to the
branch and the new tag::
git push origin {codename}
git push origin v0.xx
Development and Stable releases
-------------------------------
For a development release, update tags for ``ceph.git``::
git push origin v0.xx
git push origin HEAD:last
git checkout master
git merge next
git push origin master
git push origin HEAD:next
Similarly, for a development release, for both ``teuthology.git`` and ``ceph-qa-suite.git``::
git checkout master
git reset --hard origin/master
git branch -f last origin/next
git push -f origin last
git push -f origin master:next
