Gurobi with Docker Image

[Akhilesh Soni]

Hi,

I am trying to build a docker image based on python and integrating Gurobi with that. Can someone provide any insight as of how to proceed?

[Akhilesh Soni]

FROM python:3.6

COPY gurobi8.1.0_linux64.tar.gz /

RUN tar -xzf /gurobi8.1.0_linux64.tar.gz -C /opt/ \

  && python :/opt/gurobi810/linux64/setup.py install 

ENV PATH $PATH:/opt/gurobi810/linux64/bin

I started with python as a base image and copied gurobi zip file. The process runs as fllowing:

Step 1/5 : FROM python:3.6

 ---> 70f6aab434cf

Step 2/5 : MAINTAINER Akhilesh Soni

 ---> Using cache

 ---> 998a0c3fd988

Step 3/5 : COPY gurobi8.1.0_linux64.tar.gz /

 ---> Using cache

 ---> 69284ff22a6f

Step 4/5 : RUN tar -xzf /gurobi8.1.0_linux64.tar.gz -C /opt/   && python :/opt/gurobi810/linux64/setup.py install

 ---> Running in 9e33d51227e3

python: can't open file ':/opt/gurobi810/linux64/setup.py': [Errno 2] No such file or directory

The command '/bin/sh -c tar -xzf /gurobi8.1.0_linux64.tar.gz -C /opt/   && python :/opt/gurobi810/linux64/setup.py install' returned a non-zero code: 2

Hi Akhilesh,

You may have an extra ':' in your command.

Here is what I usually do:

FROM python:3.6

COPY gurobi8.1.0_linux64.tar.gz /tmp

RUN mkdir -p /opt && tar xfz /tmp/gurobi8.1.0_linux64.tar.gz -C /opt

ENV GUROBI_HOME /opt/gurobi810/linux64

ENV PATH $PATH:$GUROBI_HOME/bin

ENV LD_LIBRARY_PATH $GUROBI_HOME/lib

RUN cd $GUROBI_HOME && python setup.py install

Note that in order to use Gurobi in a Docker container, you will need to use one of these options:

- a token server running outside Docker (floating license) 

- or compute server running outside Docker (compute server license),

- or Gurobi Instant Cloud (cloud license).

Thanks, Michel. Yes : was redundant but I got the same error even after removing : I am not sure what am I doing wrong.

However, I tried with your code and I got the error "No License Found". Hence, I think at least the image creation went fine.

We are going to use a token server running outside Docker(floating license).

Thanks for your prompt response.
