Hi Team,
- We want to learn how to pass user name and password for MATLAB via bash script.
- Once the container job rub is completed, we want to end the MATLAB session. We are facing below session error when re-running the container probably as the session has not ended in previous run.
ERROR:
License Manager Error -4
Maximum number of users for MATLAB reached. Try again later

Hi Shyamal Agarwal,
I understand you want to launch MATLAB docker container non-interactively.
By default MATLAB container is configured to use Online Licensing so if you have an individual license or your organization is setup to use Online Licensing it prompts to enter your MathWorks Account username and password.
Online Licensing isn't always an option and in some cases isn't a desired workflow. Instead you can use run the container using license server instead.
You can specify the license server you want the container to acquire licenses from by passing an environment variable with the "-e" option when you launch a container. This will set up an environment variable within the container. MATLAB conveniently looks for MLM_LICENSE_FILE when starting and will use it for license authentication.
docker run -it --rm -e MLM_LICENSE_FILE=27000@<IP of your License server> mathworks/matlab
