# Google Compute Engine Graceful Shutdown 

This tool monitors an Instance Group for changes. The moment the given Instance Template

is no longer part of the monitored Instance Group, `on-shutdown` is run. Afterwards

the Instance is deleted via an API call.

It does not currently trigger if:

* Instance is deleted

* Instance is restarted

* Instance is re-created during autohealing

## Motivation

Google Shutdown Scripts are unreliable and only run for 60-90s max.

## Usage

```

./gce-graceful-shutdown -on-shutdown 'docker stop --time 30 my-container' -timeout 30s 

```
