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".
