Description
|
|
-----------
|
|
|
|
TripleO CI test framework.
|
|
|
|
Tools to help run CI jobs for TripleO. Includes things like:
|
|
|
|
* Shell scripts to help execute jobs on CI slave nodes (Jenkins slaves)
|
|
* A test environment broker framework which uses a client-server
|
|
model to execute jobs on a remote bare metal machine in an isolated
|
|
test environment (using VMs).
|
|
* Image elements to help build images for the test environment
|
|
broker nodes.
|
|
* Heat templates to help deploy and maintain test environment nodes
|
|
using an undercloud.
|
|
* Helper script(s) to generate CI status reports. (tox -ecireport -- -f)
|
|
|
|
|
|
OpenStack Infrastructure is deploying multiple jobs with different scenarios.
|
|
OpenStack services are balanced between different scenarios because OpenStack
|
|
Infastructure Jenkins slaves can not afford the load of running everything on
|
|
the same node.
|
|
|
|
Usage Details
|
|
-------------
|
|
|
|
Job parameters are configured in ``toci_gate_test.sh``. Control passes to
|
|
one of the ``toci_instack_*.sh`` scripts (depending on the type of job being
|
|
run) which do environment-specific setup. These scripts then call
|
|
``scripts/deploy.sh`` to run the actual deployment steps. For most things,
|
|
``deploy.sh`` simply calls ``scripts/tripleo.sh`` with the appropriate
|
|
parameters.
|
|
|
|
In ascii art, the flow of the scripts would look like:
|
|
|
|
toci_gate_test -> toci_instack_* -> deploy.sh -> tripleo.sh
|
|
|
|
There's some additional complexity that this description glosses over, but
|
|
for the most part only tripleo-ci admins need to worry about it.
|
|
|
|
temprevert, cherry-pick, pin
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
There are three functions available in tripleo-ci which can be used to alter
|
|
the git repos of non-tripleo projects that are used in tripleo-ci. They only
|
|
work on projects that are part of OpenStack. Use of these should
|
|
be avoided whenever possible as any changes made during a ci run will not
|
|
apply to regular users of TripleO. However, they can be useful for determining
|
|
which commit broke something, and in rare cases we may want to use them
|
|
until a project can sort out a problem itself.
|
|
|
|
To apply one of these functions during a ci run, add it to the appropriate
|
|
location in the ``toci_instack_*.sh`` script. There should be a comment that
|
|
says "Tempreverts/cherry-picks/pins go here."
|
|
|
|
.. note:: Do not include the bug number in the commit message where you
|
|
propose adding one of these functions. Any change whose commit
|
|
message includes a reference to the bug will not apply the function.
|
|
This is to allow testing of patches intended to fix the bug.
|
|
|
|
.. warning:: As of this writing, these functions all apply against the latest
|
|
master branch of the project in question. They do not respect
|
|
the current-tripleo repo versions.
|
|
|
|
* temprevert
|
|
|
|
Revert a commit from a project. Takes 3 parameters: project, commit id,
|
|
and bug number. Example::
|
|
|
|
temprevert neutron 2ad9c679ed8718633732da1e97307f9fd9647dcc 1654032
|
|
|
|
* pin
|
|
|
|
Pin to a commit from a project. This usually is not necessary now that our
|
|
repos are gated by the promotion jobs. Takes 3 parameters: project,
|
|
commit id, and bug number. Example::
|
|
|
|
pin neutron 2ad9c679ed8718633732da1e97307f9fd9647dcc 1654032
|
|
|
|
* cherrypick
|
|
|
|
Cherry-pick an active review from a project. Takes 3 parameters: project,
|
|
Gerrit refspec, and bug number. The Gerrit refspec can be found under the
|
|
download button of the change in question. Example::
|
|
|
|
cherrypick neutron refs/changes/49/317949/28 1654032

Service testing matrix
|
|
----------------------
|
|
|
|
The CI testing matrix for all scenarios is defined in
|
|
`tripleo-heat-templates <https://git.openstack.org/cgit/openstack/tripleo-heat-templates/tree/README.rst>`_.
|
|
This matrix describes the services that will run in each environment.
