# kubernetes-e2e-{gce, gke, gke-ci} jobs: This script is triggered by
# the kubernetes-build job, or runs every half hour. We abort this job
# if it takes more than 75m. As of initial commit, it typically runs
# in about half an hour.
#
# The "Workspace Cleanup Plugin" is installed and in use for this job,
# so the ${WORKSPACE} directory (the current directory) is currently
# empty.
