This introduces three different parts of a job designed to run
on a custom runner managed by Red Hat. The goals include:
a) propose a model for other organizations that want to onboard
their own runners, with their specific platforms, build
configuration and tests.
b) bring awareness to the differences between upstream QEMU and the
version available under CentOS Stream, which is "A preview of
upcoming Red Hat Enterprise Linux minor and major releases".
c) because of b), it should be easier to identify and reduce the gap
between Red Hat's downstream and upstream QEMU.
The components of this custom job are:
I) OS build environment setup code:
- additions to the existing "build-environment.yml" playbook
that can be used to set up CentOS/EL 8 systems.
- a CentOS Stream 8 specific "build-environment.yml" playbook
that adds to the generic one.
II) QEMU build configuration: a script that will produce binaries with
features as similar as possible to the ones built and packaged on
CentOS stream 8.
III) Scripts that define the minimum amount of testing that the
binaries built with the given configuration (point II) under the
given OS build environment (point I) should be subjected to.
IV) Job definition: GitLab CI jobs that will dispatch the build/test
jobs (see points #II and #III) to the machine specifically
configured according to #I.

Custom CI/CD variables
|
|
======================
|
|
|
|
QEMU CI pipelines can be tuned by setting some CI environment variables.
|
|
|
|
Set variable globally in the user's CI namespace
|
|
------------------------------------------------
|
|
|
|
Variables can be set globally in the user's CI namespace setting.
|
|
|
|
For further information about how to set these variables, please refer to::
|
|
|
|
https://docs.gitlab.com/ee/ci/variables/#add-a-cicd-variable-to-a-project
|
|
|
|
Set variable manually when pushing a branch or tag to the user's repository
|
|
---------------------------------------------------------------------------
|
|
|
|
Variables can be set manually when pushing a branch or tag, using
|
|
git-push command line arguments.
|
|
|
|
Example setting the QEMU_CI_EXAMPLE_VAR variable:
|
|
|
|
.. code::
|
|
|
|
git push -o ci.variable="QEMU_CI_EXAMPLE_VAR=value" myrepo mybranch
|
|
|
|
For further information about how to set these variables, please refer to::
|
|
|
|
https://docs.gitlab.com/ee/user/project/push_options.html#push-options-for-gitlab-cicd
|
|
|
|
Here is a list of the most used variables:
|
|
|
|
QEMU_CI_AVOCADO_TESTING
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
By default, tests using the Avocado framework are not run automatically in
|
|
the pipelines (because multiple artifacts have to be downloaded, and if
|
|
these artifacts are not already cached, downloading them make the jobs
|
|
reach the timeout limit). Set this variable to have the tests using the
|
|
Avocado framework run automatically.
|
|
|
|
AARCH64_RUNNER_AVAILABLE
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
If you've got access to an aarch64 host that can be used as a gitlab-CI
|
|
runner, you can set this variable to enable the tests that require this
|
|
kind of host. The runner should be tagged with "aarch64".
|
|
|
|
S390X_RUNNER_AVAILABLE
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
If you've got access to an IBM Z host that can be used as a gitlab-CI
|
|
runner, you can set this variable to enable the tests that require this
|
|
kind of host. The runner should be tagged with "s390x".
|
|
|
|
CENTOS_STREAM_8_x86_64_RUNNER_AVAILABLE
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
If you've got access to a CentOS Stream 8 x86_64 host that can be
|
|
used as a gitlab-CI runner, you can set this variable to enable the
|
|
tests that require this kind of host. The runner should be tagged with
|
|
both "centos_stream_8" and "x86_64".
