Subject [jira] [Commented] (SINGA-430) Rafiki--Creat inference error.
Date Mon, 04 Mar 2019 08:27:00 GMT


Ngin Yun Chuan commented on SINGA-430:

Hi Liu Hui,

Whenever a new inference job is created, Rafiki selects a free port to use for the job's predictor,
starting from port 30000, and it determines which ports are free based on its database of
inference jobs. If there was an existing Docker container/service using a port not captured
in that instance of Rafiki, there'll be that error. 

In Rafiki's code, maybe we should better handle the error to try successive ports, if creation
of a predictor at a port fails. Will be adding this to our list of TODOs.

> The hint is "port '30000' is already in use",I think that the problem happened when docker
swarm try to create new docker for inference.
> Issue  can be tested on the machine
