Execute a Matlab script from Docker container

Hello,

I have a very basic matlab file called hello_world.m that just create a simple .csv file. My goal is now to try to execute this matlab script from a Docker container. This is my Dockerfile:

FROM mathworks/matlab:r2024a
ENV MLM_LICENSE_FILE /licenses
USER root
RUN mkdir -p /licenses /matlab_script
COPY license.lic /licenses/license.lic
COPY hello_world.m /matlab_script/hello_world.m
WORKDIR /matlab_script
CMD ["matlab", "-batch", "hello_world"]

The license.lic attatched is a "DEMO" license.

This is the command I use to run my container:

docker run --rm -v $(pwd)/license.lic:/licenses/license.lic matlab-demo

Error l

ogs: 

License checkout failed.
License Manager Error -9
Your username does not match the username in the license file. 
To run on this computer, you must run the Activation client to reactivate your license.

Is it because I am using a "demo"license?

You can refer to the following MATLAB Answer to help troubleshoot license related issues:

I hope this helps!

Thanks, The activation is not present under the bin folder and nowhere else:

find . -name "activate_matlab.sh"
# no results 

Also, 1 licence = 1 machine, so how can I take a license that was installed on my windows destop to a docker image since the host_id will be different?
