Not able to login form docker image for 1 month trail subscription?

Hi Support team.

I am trying to do MATLAB login from docker image, but my login is failing.

Note:- I am using 1 month free trial login credetials.

Docker file and error image I have given below.

Docker File:-

# Use MATLAB base image from MathWorks

FROM mathworks/matlab:r2023b

# Set the working directory inside the container

WORKDIR /usr/src/matlab

# Copy your MATLAB conversion script to the container

COPY convert_mf4_to_csv.m .

## Environment varibales for MathWorks credentials

ENV MW_USERNAME = "{User_email}"

ENV MW_PASSWORD = "{password}"

# Expose the port for communication (if needed)

EXPOSE 8080

# The default command will pass arguments for input and output paths

CMD ["matlab", "-batch", "convert_mf4_to_csv('/x_input_folder/input_file.mf4', '/x_output_folder/output_file.csv')"]

Error:-

MATLAB is selecting SOFTWARE OPENGL rendering.

Please enter your MathWorks Account email address and press Enter:

Sign-in failed. Would you like to retry? y/n [n]

Docker command I am runing given below:-

docker run --rm -v C:\\Users\\vdube\\Desktop\\workplace\\mf4tocsv\\input_mf4_files:/x_input_folder -v C:\\Users\\vdube\\Desktop\\workplace\\mf4tocsv\\output_csv_folder:/x_output_folder -e MW_USERNAME={email} -e MW_PASSWORD={password} matlab-mf4-converter

Hi @Viplav

AFAIK, It is not possible for you to use your Online Licensing credentials non-interactively.

I also do not recognize these environment variables:

ENV MW_USERNAME = "{User_email}"
ENV MW_PASSWORD = "{password}"

Could you please verify that you are able to run the container interactively using your online licensing credentials? By running the container as shown below:

docker build -t mymatlab .
docker run -it --rm mymatlab

Thanks AFAIK for responce!

After building and running the docker I can able to sign in. I cant see any sign in message. Below is the screen shot attached.

I had less confidence on below env variable too. I removed it from my dockerfile and passing cred from docker ru command as given below

ENV MW_USERNAME = "{User_email}"

ENV MW_PASSWORD = "{password}"

docker run --rm -v C:\\Users\\vdube\\Desktop\\workplace\\mf4tocsv\\input_mf4_files:/x_input_folder -v C:\\Users\\vdube\\Desktop\\workplace\\mf4tocsv\\output_csv_folder:/x_output_folder -e MW_USERNAME={email} -e MW_PASSWORD={password} matlab-mf4-converter
