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.
Currently, this can be avoided by killing all applications using ports > 30000
on the deployed machine.
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.
Thanks!

> Issue Type: Bug
> Reporter: Liu Hui
> Priority: Major
> Attachments: err.log
>
>
> When I ran a task of image identification on rafiki which showed in Rafiki's
> User Guide.
> I have created and trained model successfully.
> But a error occurred when I try to create an inference.The error log shows in
> attachment.
> 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 221.224.36.165:/home/liuhui/rafiki.
