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)
- Helper getthelogs script to download important job logs locally. Then you may want to inspect the logs for known errors and contribute discovered search patterns as the elastic-recheck queries.
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
On March 2017, the ansible quickstart framework was added to TOCI to gradually replace the bash scripts that drove the jobs. Part of the original framework has been changed to allow the new framework to handle jobs, but maintaining backwards compatibility with the original framework while jobs are being transitioned
TOCI entry point
Upon starting a job, based on the configuration of its layout, zuul
will call devstack-gate, which is needed for the basic nodepool node
setup, but will then pass the control to toci_gate_test.sh
.
During the transition, this will be a symbolic link to
toci_gate_test-oooq.sh
.
Quickstart Transition scripts
The initial part of toci_gate_test-oooq.sh
script
decides whether to exec the original workflow or continue with the
quickstart workflow, based on the job type passed down by zuul layout
parameters. To move a job to the new quickstart framework, it is enough
to propose a change to zuul layout to add a "featureset" keyword on its
type. When using the quickstart workflow, the rest of the script will
assemble a set of arguments to pass to quickstart scripts, based on the
components of the job type separated by dashes e.g. a job type value of
"periodic-ovb-featureset001" will make the script assemble arguments to
deal with "ovb" provisioning, and set featurset001 to be the test matrix
for the job. This script will also invoke the test environment broker to
create the proper ovb environment. At the end the
toci_gate_test-oooq.sh
will pass control to
toci_quickstart.sh
script that will actually call
quickstart with its parameters.
Quickstart Framework
toci_quickstart.sh
consists of three parts, setup, invocationo and logs collection.
For more information about feature sets and test matrix please see .. _Featureset Documentation: https://docs.openstack.org/developer/tripleo-quickstart/feature-configuration.html from quickstart documentation The new workflow uses the directory toci-quickstart/ to store TripleO ci specific configurations, roles or playbooks for the quickstart workflow The parts of quickstart under scripts/ are instead handled by the original framework only
Original Framework
Job parameters are configured in toci_gate_test-orig.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. This matrix describes the services that will run in each environment.
