Install applications in workers

[karimDev13]

Please i've a question , can i install other applications in each worker on graphscope ?

Definitely yes.

You could build a docker image from the graphscope's image: registry.cn-hongkong.aliyuncs.com/graphscope/graphscope:0.16.0.

e.g.,

FROM registry.cn-hongkong.aliyuncs.com/graphscope/graphscope:0.16.0

RUN pip3 install ...

And then use your own image to launch graphscope session by:

session = graphscope.session("k8s_gs_image=...")

Hi @karimDev13,

May I know more details about your "applications"? e.g., which component your application want to connect to? Vineyard?

[karimDev13]

@sighingnow the application is a new interactive engine (with python library) that must be connected to each worker.

[sighingnow]

that must be connected to each worker.

Which worker? GAE or GIE or GLE?

[karimDev13]

graph interactive engine (GIE) exactly each node containing fragment of the partitioned graph instance must be connected to this interactive engine for parallel execution.

How would you like to connect to the GIE worker process inside the pod? As far as I know GIE engine process doesn't expose something like TCP socket or HTTP server to allow establishing external connections.
