GCE shutdown-script with CoreOS

[Chad Autry]

I've entered a shutdown-script and a startup-script into the Custom Metadata of my GCE instance running CoreOS.

The startup-script executes perfectly, but I don't see any evidence the shutdown-script is even invoked. I've tried shutting down from the console, and by executing 'sudo shutdown' 

I've attached a picture of me Custom Metadata.

Anyone else have the same issue or spot what my problem is?

Hey Chad,

The following command in shut-down script kills the container:

sudo docker exec mc_server /bin/sh /usr/bin/containerizedMinecraftServer.sh exec "say The Virtual Machine is being shut down. Turning off saves and backing up the world."

It seems a line in containerizedMinecraftServer.sh script which writes to a named pipe file ( /tmp/srv-input) inside the container is causing of the issue.

Sincerely,

[Chad Autry]

That command works as expected when executed from the console and not invoked from a shutdown-script.

Anyways, to take the internals of the command out of the question, I edited my shutdown-script to have

echo 'shutdown-script test' | sudo tee --append /minecraft/shutdownTest.log

as the first line.

When shutting down the VM, then restarting I don't see the file. /minecraft is a mounted persistent disk if that matters.
