|
# Note: on buildbot VMs (where there is no environment cleanup), the
|
|
# kubernetes test server may be kept running if the script aborts or
|
|
# is aborted (buildbot master failure!) for some reason. As such we
|
|
# execute it under "timeout" control, which ensure it always is
|
|
# terminated. It's not a 100% great method, but hopefully does the
|
|
# trick. -- rgerhards, 2018-07-21
