Build and Set-Up WWTP container based on Matlab

Create your own Matlab Simulink Docker image

Run the MATLAB container using this command: docker run -it -p 5901:5901 -p 6080:6080 --shm-size=512M mathworks/matlab:r20XYz -vnc
- :r20XYz chooses the release version of the MATLAB container. E.g.: r2022a
- Open a bash for the Matlab container: e.g.: docker exec -it <containerID> bash.
- Run Matlab with root permissions: sudo matlab.
- Install Industrial Control Communication Toolbox as add-on:
- Install Matlab Simulink as add-on:
- Install gcc, g++, foltran:
  - sudo apt-get update
  - sudo apt-get install -y gcc g++ gfortran
- Save changes in container
  - docker ps
  - docker commit <containerID> <repository>:<tag>
    - E.g.: docker commit 3d555451f07a mymatlab:r2020a.

Use the matlab simulink image created for the project

Open docker-compose file cd ~/ICSVirtual/network/ICSNetwork.
Change the image of the matlab service by sflorenz05/matlab_simulink:v0.3.

Reference to the Modbus Module used

Build final image

It has been created a Dockerfile that ADD the source code into the container base image: sflorenz05/matlab_simulink:v0.3.
In this way, the image sflorenz05/matlab_simulink:v0.4 has been built.

Troubleshootings Matlab on Docker

Import Project Files into the PATH before start simulation

Compile all `*.c` using mex compiler of Matlab

The *.c version of all of the following folders must be compiled using mex:
All files has been compiled by default.
- E.g.: If we go inside the ASU Unit folder (see the PATH in the following image) we only need to compile the *.c, using the command mex ASU_UNIT.c. Important: *.mexa64 files are generated.

Run Simulink Project

Once all the code has been successfully compiled the Simulink Project is executed with double clic in the *.slx. E.g.: Remedy_WWTP.slx.
The values displayed on the displays should be close to the values highlighted in the following figure.
