# We use https://gitlab.freedesktop.org/freedesktop/ci-templates
# to build the images used by the ci.
#
# Here is how to properly update those images:
# - new Rust stable version: update GST_RS_IMG_TAG and update Rust version
# - add dependencies: update FDO_DISTRIBUTION_PACKAGES and update GST_RS_IMG_TAG
# - update GStreamer version: update the tag in ci/install-gst.sh and update GST_RS_IMG_TAG
#
# GST_RS_IMG_TAG is defined in ci/images_template.yml and should be updated
# either by:
# - setting it to the current date and the version suffix to 0
# - incrementing the version suffix
#
# After each update commit your changes and push to your personal repo.
# After review and ci approval merge the branch as usual.
#
# Updating the nightly image should be done by simply running a scheduled ci
# pipeline on the upstream repo with the $UPDATE_NIGHTLY variable defined.
