ohad israeli commented on TINKERPOP-2359:
-----------------------------------------

I did use g.io by the end which was fine for saving data on demand but i am 
still looking for a way to persist in mem data upon process termination to the 
disk without the need for one to ondemand to the save.

I did spot the blog post that you've mentioned and i have been able to make it 
work with simple node express process but not with tinkerpop server shell 
script 

> onShutDown not being called when docker container stopped

>             Project: TinkerPop
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.4.6
>            Reporter: ohad israeli
>            Priority: Minor
>
> When one uses groovy hooks with tinkerpop server hosted within the official 
> docker the onStartUp hook will be called at server startup but the onShutDown 
> will not be called.
> I am using tinkergraph server for local testing and i would like to persist 
> the data upon the server exit. i've added a graph.close to the onShutDown 
> hook but i havent been able to get it called.
> It will be called of course if you use the server start / server stop shell 
> script but not if you kill / stop the docker container.
> If there is some other way to persist the date i.e. call the graph.close from 
> code and note via the console it would also be great as using it from node 
> javascript i havent been able to find a way to call the graph.close directly.
