SimpleNLG Docker deployment

[Suresh Babu Golla]

Hi Saad Mahamood,

I am impressed about simpleNLG service.  

I am trying to dockerize the simpleNLG service and host in one of our central server of my organisation so that my team can use it.

The docker image is working fine in my local system, but when I deploy it in the server, we are not able to hit the service. it is throwing connection lost issue.

FYI, we are using ant to build and run the service.

Please let me know if any changes are required from config files.

Thanks & Regards

Suresh

Hi Suresh,

Just to clarify. Are you trying to use the SimpleServer to take in an XML realisation request with SimpleNLG? If so, could the issue be a port configuration issue on the remote side? The default socket port is 5007, which may not available on a cloud deployment. A different port number can be used by passing as an argument to the main method of the SimpleServer class. 

Saad.

Hi Saad,

Saad: Are you trying to use the SimpleServer to take in an XML realisation request with SimpleNLG?

Yes

I changed default socket port to 8585. still it is not working.

Thanks & Regards

Hi Suresh,

I don’t have a solution to hand unfortunately. Can I take a look at your DockerFile? Also where are you deploying the container to? AWS? GCP? Or is it a local network server?

Also can you give me the exact error message when trying to make you connection.

Hi Saad,

Please find my docker file content below:

FROM alpine

WORKDIR /nlgservice

RUN apk update && apk add openjdk8 && apk add apache-ant

# copy the content of the local directory to the working directory

COPY / .

# Publish port

EXPOSE 8585

ENTRYPOINT ["ant"]

Please find the error below:

Please suggest if any changes required in docker file

Hi Saad,

To add some more context to the above.

When I check the reachability of pod, below error I am getting

E1013 11:57:19.163871 10803 portforward.go:372] error copying from remote stream to local connection: readfrom tcp4 127.0.0.1:8585->127.0.0.1:57895: write tcp4 127.0.0.1:8585->127.0.0.1:57895: write: broken pipe

Thanks
