Hello
I want to run a docker compose with 1 matlab container and 1 app container. Running the matlab container on its own works - it interactively prompts for username, I sign in on the browser and enter OTA license in the terminal and it connects. This is the dockerfile:
```
ARG MATLAB_RELEASE=R2023b
ARG ADDITIONAL_PRODUCTS="Simulink"
FROM mathworks/matlab:$MATLAB_RELEASE
ARG MATLAB_RELEASE
ARG ADDITIONAL_PRODUCTS
USER root
RUN export DEBIAN_FRONTEND=noninteractive \
&& apt-get update \
&& apt-get install --no-install-recommends --yes \
wget \
unzip \
ca-certificates \
&& apt-get clean \
&& apt-get autoremove \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /tmp
USER matlab
RUN wget -q https://www.mathworks.com/mpm/glnxa64/mpm \
&& chmod +x mpm \
&& EXISTING_MATLAB_LOCATION=$(dirname $(dirname $(readlink -f $(which matlab)))) \
&& sudo HOME=${HOME} ./mpm install \
--destination=${EXISTING_MATLAB_LOCATION} \
--release=${MATLAB_RELEASE} \
--products ${ADDITIONAL_PRODUCTS} \
|| (echo "MPM Installation Failure. See below for more information:" && cat /tmp/mathworks_root.log && false) \
&& sudo rm -rf mpm /tmp/mathworks_root.log ${HOME}/.MathWorks
USER root
RUN apt-get update && apt-get install -y software-properties-common && \
add-apt-repository ppa:deadsnakes/ppa && \
apt-get update && apt-get install -y python3.9 python3-pip
RUN cd /opt/matlab/$MATLAB_RELEASE/extern/engines/python && \
python3 setup.py install
USER matlab
ENV MW_DDUX_FORCE_ENABLE=true MW_CONTEXT_TAGS=$MW_CONTEXT_TAGS,MATLAB:TOOLBOXES:DOCKERFILE:V1
WORKDIR /home/matlab
```
However, when I run in as part of a docker compose, it prompts me for my password and it fails infinite times:
```

✔ Container dev-app-1 Created 0.1s

I am not able to download a license file. Is there any other way to solve this?

Hi @Hud Bin
The issue here is with your docker compose file. It needs to be configured to notify the container to run in interactively.
# docker-compose.yml
version: "3"
services:
matlab:
image: mathworks/matlab:r2023b
stdin_open: true # docker run -i
tty: true # docker run -t
app:
image: nginx
ports:
- "81:80"
depends_on:
- matlab
restart: always
Then start the services using:
docker compose up -d
[+] Building 0.0s (0/0)
[+] Running 3/2
✔ Network 2105411_default Created 0.1s
✔ Container 2105411-matlab-1 Created 0.0s
✔ Container 2105411-app-1 Created 0.0s
Finally, attach to the running matlab container using:
docker attach 2105411-matlab-1
Replace 2105411-matlab-1 with the name of the running container in your environment
When you are attached here, you will see an empty screen because the text prompting you for the email address was already printed before you could attach.
To continue, enter your email address and follow the prompts as shown below:
docker attach 2105411-matlab-1
your-email-address@mathworks.com
Single-Sign-On(SSO) is not available in this environment. You need a one-time password to sign in to MATLAB.
Step 1. Visit https://www.mathworks.com/mwa/otp
Step 2. Copy the password.
Step 3. Return here, and input the password.
Please enter the one-time password:

To avoid the empty screen when you attach to the matlab container you could update the entrypoint in the docker compose file to /usr/bin/bash so that when you attach into the container, you will be presented with a BASH prompt. There you could execute the default entrypoint for the mathworks/matlab container ie: run.sh
# docker-compose.yml
version: "3"
services:
matlab:
image: mathworks/matlab:r2023b
entrypoint: /usr/bin/bash
stdin_open: true # docker run -i
tty: true # docker run -t
app:
image: nginx
ports:
- "81:80"
depends_on:
- matlab
restart: always
Start the services in detached mode:
docker compose -d
[+] Building 0.0s (0/0)
[+] Running 3/3
✔ Network 2105411_default Created 0.1s
✔ Container 2105411-matlab-1 Started 0.8s
✔ Container 2105411-app-1 Started 1.4s
Attach to the matlab container
docker attach 2105411-matlab-1
matlab@35ded52975da:~/Documents/MATLAB$ run.sh

Thank you @Prabhakar - I kinda solved it by interactively authenticating via the web and committing to a new docker container image
