# ISTIO_API_GIT_SOURCE allows to override the default Istio API repository, https://github.com/istio/api@$(SOURCE_BRANCH_NAME)
# with, for example, a mapped local directory: file:///work/istio/api@branch-name when running `update_ref_docs`.
#
# The format for ISTIO_API_GIT_SOURCE value is {GIT_URL}@{TARGET_BRANCH_NAME}.
#
# Note that when running with BUILD_WITH_CONTAINER=1, we can map the local directory by setting
# the ADDITIONAL_CONTAINER_OPTIONS environment variable as shown in the below example:
#
# $ BUILD_WITH_CONTAINER=1 \
#   ISTIO_API_GIT_SOURCE="file:///work/istio/api@branchname" \
#   ADDITIONAL_CONTAINER_OPTIONS="-v /path/to/local/istio/api:/work/istio/api" \
