how to debug a startup script

[iamjenechka]

Any idea how to debug execution of a startup script?

I already tried

exec 5> >(systemd-cat -t $0)
BASH_XTRACEFD="5"
PS4='$LINENO: '
set -x

without any success

You can check the syslog for details.

Or SSH into the VM and re-excute the script: https://cloud.google.com/compute/docs/startupscript#rerunthescript

I forgot to say, that I already checked journalctl and found nothing.

I'll try the the second thing. Thanks.

google_metadata_script_runner --script-type startup --debug works just fine
