The problem I reported seems to be gone. But now there is another. In the
start-worker.sh script I have:
#!/bin/sh
I=$1
P=...
Z=...
# According to `gcloud compute instances start --help` this is sync.
gcloud compute --project $P instances start --zone $Z $I || exit 1
finish() {
# Shutdown.
echo 3 >> /tmp/x
gcloud compute --project $P instances stop --zone $Z $I >> /tmp/x
}
trap finish EXIT
# "What Jenkins expects from your script is that, in the end, it has to
execute
# the agent program like java -jar agent.jar, on the right computer, and
have
# its stdin/stdout connect to your script's stdin/stdout."

echo 1 >> /tmp/x
gcloud compute --project $P ssh --zone $Z $I --command 'wget "
http://10.132.0.20:8080/jnlpJars/agent.jar"; -O agent.jar && java -jar
agent.jar'
echo 2 >> /tmp/x
The agent is started fine, the job being run fails as expected, but then
"echo 2" is never executed. Not even "echo 3" which should be executed when
the scripts exits. It seems as if the script process is killed -9. This is
a problem because the instance I started cannot be brought down using this
nice synchronous mechanism provided by "gcloud compute instances
start/stop".
This is what I see in the node log:

Any idea what's going on? Should I file a bug or am I using it incorrectly?
